PREFACE 

On December 8, 1993, Title VI of the North American Free Trade Agreement Implementation 

Act (Pub. L. 103-182, 107 Stat. 2057), also known as the Customs Modernization or “Mod” Act, 

became effective. These provisions amended many sections of the Tariff Act of 1930 and 

related laws. 

Two new concepts that emerge from the Mod Act are “informed compliance” and “shared 

responsibility,” which are premised on the idea that in order to maximize voluntary compliance 

with laws and regulations of U.S. Customs and Border Protection, the trade community needs to 

be clearly and completely informed of its legal obligations. Accordingly, the Mod Act imposes a 

greater obligation on CBP to provide the public with improved information concerning the trade 

community's rights and responsibilities under customs regulations and related laws. In addition, 

both the trade and U.S. Customs and Border Protection share responsibility for carrying out 

these requirements. For example, under Section 484 of the Tariff Act, as amended (19 U.S.C. 

1484), the importer of record is responsible for using reasonable care to enter, classify and 

determine the value of imported merchandise and to provide any other information necessary to 

enable U.S. Customs and Border Protection to properly assess duties, collect accurate 

statistics, and determine whether other applicable legal requirements, if any, have been met. 

CBP is then responsible for fixing the final classification and value of the merchandise. An 

importer of record’s failure to exercise reasonable care could delay release of the merchandise 

and, in some cases, could result in the imposition of penalties. 

Regulations and Rulings (RR) of the Office of International Trade has been given a major role in 

meeting the informed compliance responsibilities of U.S. Customs and Border Protection. In 

order to provide information to the public, CBP has issued a series of informed compliance 

publications on new or revised requirements, regulations or procedures, and a variety of 

classification and valuation issues. 

This publication, prepared by the National Commodity Specialist Division of Regulations and 

Rulings is entitled "Table and Kitchen Glassware”. It provides guidance regarding the 

classification of these items. We sincerely hope that this material, together with seminars and 

increased access to rulings of U.S. Customs and Border Protection, will help the trade 

community to improve voluntary compliance with customs laws and to understand the relevant 

administrative processes. 

The material in this publication is provided for general information purposes only. Because 

many complicated factors can be involved in customs issues, an importer may wish to obtain a 

ruling under Regulations of U.S. Customs and Border Protection, 19 C.F.R. Part 177, or to 

obtain advice from an expert who specializes in customs matters, for example, a licensed 

customs broker, attorney or consultant. 

Comments and suggestions are welcomed and should be addressed to U.S. Customs and 

Border Protection, Office of International Trade, Executive Director, Regulations and Rulings, 

799 9th Street N.W. 7th floor, Washington, D.C. 20229-1177.

INTRODUCTION 

This informed compliance publication focuses on the classification of glassware used for 

table or kitchen purposes. These types of products are imported in great quantities and 

are often classified incorrectly. The publication will discuss many of the classification 

issues connected with this merchandise and will provide guidance to enable importers 

and Customs brokers to avoid classifying these products incorrectly. 

 

Household glassware is classifiable in heading 7013 of the Harmonized Tariff Schedule 

of the United States (HTSUS). This heading provides for drinking glasses; other 

glassware for table and kitchen purposes; and glassware for toilet, office, indoor 

decoration or similar purposes. The following chart indicates the broad categories of 

glassware covered by heading 7013. 

Stemware Drinking Glasses of Lead Crystal Subheading 7013.22 

Other Stemware Drinking Glasses Subheading 7013.28 

Other Drinking Glasses of Lead Crystal Subheading 7013.33

SUBHEADINGS BASED ON UNIT VALUE 

 

Most of the eight digit subheadings that appear under heading 7013 of the HTSUS 

provide for glassware based on the unit value of a single glass article. The following 

chart indicates the subheadings based on unit value which apply to table and kitchen 

glassware, other than lead crystal.

Table and Kitchen Glassware 

March 2010 

Importers and Customs brokers often enter glassware incorrectly under subheadings 

based on the value of several glass articles packed together. In fact, the heading 7013 

subheadings based on value are dependent on the unit value of a single glass 

article, not the value of several articles packed together. 

Example 1: Eight drinking glasses (not stemware) are packed together and sold by the 

foreign firm to the American importer at a price of $5.60 for the set of eight. However, 

the value of a single glass is only seventy cents. How is the merchandise classified? 

Answer: The drinking glasses are classified in subheading 7013.37.20, HTSUS, under 

the provision for drinking glasses...valued over thirty cents but not over three dollars 

each. The unit value of a single glass determines the applicable subheading, not the 

value of the eight glasses packed together.

Example 2: A punch bowl and six drinking glasses are packaged together as a set. The 

set is sold by the foreign firm to the American importer for a price of $5.50. The value of 

the punch bowl is $2.50. The value of each drinking glass is fifty cents. How is the set 

classified? 

Answer: The set is classified in subheading 7013.49.20, HTSUS, as other table/kitchen 

glassware valued not over three dollars each. Under General Rule of Interpretation 

(3)(b) [GRI (3)(b)] of the HTSUS, the punch bowl represents the essential character of 

the set. Therefore, the entire set is classified based on the six digit subheading that 

applies to the punch bowl (7013.49, HTSUS), not the six digit subheading that provides 

for the drinking glasses (7013.37 HTSUS). The unit value of the punch bowl alone 

determines the applicable eight digit subheading (7013.49.20, HTSUS), not the 

combined value of the bowl and glasses. 

TYPES OF TABLE AND KITCHEN GLASSWARE 

The provisions for drinking glasses in subheadings 7013.28 and 7013.37, HTSUS cover 

ordinary drinking glasses, glass goblets, glass mugs (other than purely decorative glass 

mugs covered by subheading 7013.99, HTSUS), glass tankards, etc. 

The provision for other table/kitchen glassware in subheading 7013.49, HTSUS covers 

a wide variety of glass articles used in the kitchen or on the table including pitchers, 

decanters, jugs, glass storage articles, dishes, bowls, plates, egg cups, basins, trays, 

ice buckets, infants’ feeding bottles, salt and pepper shakers, plate warmers, coasters, 

cruets and numerous other table and kitchen products. 

Glass-Ceramics 

Subheading 7013.10 of the HTSUS provides for glassware of glass-ceramics. Material 

referred to as “glass-ceramics” is produced when glass is converted into an almost 

wholly crystalline substance by a process of controlled crystallization. 

9
Table and Kitchen Glassware 

March 2010 

These types of articles are produced when the manufacturer adds nucleating agents 

(e.g., metal oxides such as titanium dioxide and zirconium oxide or metals such as 

copper powder) to the glass batch. After the product is shaped by ordinary glassmaking methods, it is maintained at a temperature that allows the glassy body to 

crystallize around the nucleating agents (devitrification). 

Analysis of a sample by the U.S. Customs laboratory is necessary to enable U.S. 

Customs to determine whether a product consists of glass-ceramics. 

Lead Crystal Glassware 

Lead crystal glassware classifiable in the HTSUS subheadings 7013.22 (stemware 

drinking glasses), 7013.33 (other drinking glasses), 7013.41 (other table/kitchen 

glassware) and 7013.91 (decorative glassware) must contain at least 24 percent lead 

monoxide by weight. See Subheading Note 1 to Chapter 70 of the HTSUS. 

Frequently glass products that contain less than 24 percent lead monoxide by weight 

are entered incorrectly under the provisions for lead crystal glassware. Samples of 

glass articles claimed to be lead crystal are sent to the U.S. Customs laboratory to verify 

their composition. An importer who claims that a product is lead crystal should 

ascertain before entry whether the item truly contains at least 24 percent lead monoxide 

by weight. 

Like the provisions for ordinary glassware (subheadings 7013.28, 7013.37, 7013.49 and 

7013.99, HTSUS), the provisions for lead crystal glassware (subheadings 7013.22, 

7013.33, 7013.41 and 7013.91, HTSUS) are subdivided into various eight digit 

subheadings which describe the products based on the unit value of a single glass 

article. 

Specially Tempered Glassware 

The HTSUS subheadings 7013.28.05, 7013.37.05. 7013.49.10 and 7013.99.20 provide 

for specially tempered glassware. These provisions cover glass articles which have 

been pressed and toughened; this process makes these articles considerably 

stronger than ordinary glassware. Often glass articles which might have been 

“tempered” (i.e., strengthened in some way) have not been “specially tempered” 

(strengthened by means of pressing and toughening). 

Items that have not been specially tempered are frequently entered incorrectly under 

the provisions for specially tempered glassware. These products are correctly 

classifiable under the appropriate heading 7013 subheading based on unit value. 

Analysis by our U.S. Customs laboratory is crucial to verify claims that glass 

articles are specially tempered. 

10
Table and Kitchen Glassware 

March 2010 

The U.S. Customs laboratory protocols for testing glass articles to determine whether 

they are specially tempered are found in Treasury Decision 94-26 (TD 94-26), Customs 

Bulletin, vol. 28, no. 13, March 30, 1994; Federal Register, March 22, 1994 (59 FR 

13531). 

When testing to determine whether a product is pressed and toughened (specially 

tempered), the laboratory analyst initially does a visual examination. The presence of 

mold marks, ribs, handles or flutes in a glass article often indicates that an article has 

been “pressed.” The absence of these characteristics makes it much less likely that the 

item has been pressed. 

The analyst then measures both the minimum diameter of the mouth, opening or upper 

rim of the sample and the maximum inside diameter. This process is known as the 

dimensional test. A sample that has a maximum inside diameter greater than the 

minimum diameter of the mouth, opening or upper rim is not likely to have been 

“pressed.” If the dimensional test indicates the sample is not pressed, additional tests 

are not necessary. However, if the dimensional test does not negate the possibility that 

the article has been pressed, the analyst should perform the following additional tests. 

The sample is heated in an oven at a temperature of 160 degrees Centigrade for thirty 

minutes. Afterwards the sample is removed and immersed in a water bath set at a 

temperature of 25 degrees Centigrade. This effects a difference in temperature of 135 

degrees. If the sample breaks in response to this thermal shock test, this would indicate 

that the product has not been toughened and the analyst need not perform any further 

tests. However, if the sample does not break when subjected to the thermal shock test, 

the following additional test should be performed. 

The glass article is subjected to polariscopic examination. If a pattern of colors forms in 

response to polarized light, this would be evidence that the product is specially 

tempered. On the other hand, if the sample exhibits uniform coloration in response to 

the polarized light, this would indicate that the item is not specially tempered. 

The polarized light test can only be performed on transparent articles and certain 

translucent items. It cannot be performed on opaque products and those translucent 

products where there is inadequate transmission of polarized light. Therefore, for 

opaque articles and certain translucent items, the cutting test is substituted for the 

polarized light test. 

Under the cutting test, a tile saw or similar table-mounted circular saw is equipped with 

an 8 to 12 inch diameter continuous rim diamond blade designed for wet cutting glass. 

When subjected to wet cutting by this saw, a product which is specially tempered will 

break into pieces; however if the product is not specially tempered, it will be cleanly cut 

in half by the saw.

Glassware of Subheading 7013.42 

Table/kitchen glassware having a linear coefficient of expansion not exceeding five 

times ten to the minus sixth power per Kelvin within a temperature range of zero to 

three hundred degrees Centigrade is classifiable in subheading 7013.42, HTSUS. 

Analysis of a sample by the U.S. Customs Laboratory is necessary to verify that a 

product is properly classifiable in this provision. 

As in the other provisions for glassware discussed above, subheading 7013.42 is 

subdivided into various eight digit subheadings which describe the merchandise based 

on the unit value of a single glass article (subheadings 7013.42.20, 7013.42.30 and 

7013.42.40, HTSUS) as well as a subheading (7013.42.10, HTSUS) for pressed and 

toughened (specially tempered) glassware. 

As stated above, glass products that are not specially tempered are often entered 

incorrectly as pressed and toughened (specially tempered) glassware in subheadings 

7013.28.05, 7013.37.05, 7013.49.10 and 7013.99.20, HTSUS. In the same manner, 

merchandise is frequently entered incorrectly as specially tempered in subheading 

7013.42.10, HTSUS. Very few products are correctly classifiable in this provision. It is 

unusual for a product to be both specially tempered and have a linear coefficient of 

expansion not exceeding five times ten to the minus sixth power per Kelvin within a 

temperature range of zero to three hundred degrees Centigrade. Therefore, an 

importer or broker who wishes to enter a product in subheading 7013.42.10 should be 

certain that the product has all the characteristics described in this provision. 

Analysis of a sample by the U. S. Customs Laboratory is essential to verify that 

merchandise entered in subheading 7013.42.10 is properly classified in that 

subheading. Articles correctly classifiable in subheading 7013.42.10 are very rare. 

HEADING 7010: GLASS CONTAINERS AND PRESERVING JARS 

Glass Preserving Jars 

Heading 7010 of the HTSUS provides for glass containers and preserving jars. 

Products classifiable as table and kitchen glassware in subheading 7013.49, HTSUS, 

are often entered incorrectly in heading 7010. Therefore, it is important for an importer 

of glassware to have an understanding of the types of products that are deemed to be 

preserving jars or containers classifiable in heading 7010 and the types of articles that 

would not be covered by this provision. 

12
Table and Kitchen Glassware 

March 2010 

There are only two types of products that U.S. Customs currently regards as 

preserving jars: 

1) Mason type preserving jars have always been regarded as preserving 

jars. The common self-sealing lid of a Mason type jar consists of a flat metal 

lid held in place by a metal screw band during processing. The lid is crimped 

around its bottom edge to form a trough filled with a colored gasket 

compound. 

2) Since the case of Mark D. Myers v. United States (the “Myers” case) was 

decided, glass storage articles with bail and trigger closures are 

generally regarded as preserving jars. Mark D. Myers v. United States, 

969 F. Supp. 66 (CIT 1997), published in the Customs Bulletin, vol. 31, no. 

27, July 2, 1997. 

Although glass storage articles with bail and trigger closures are generally regarded as 

preserving jars classifiable in heading 7010, tall pasta jars (a.k.a., spaghetti jars) will be 

classified as table/kitchen glassware in subheading 7013.49, not as preserving jars in 

heading 7010, even if these items have bail and trigger closures. 

Although glass storage articles with bail and trigger closures are generally regarded as 

preserving jars classifiable in heading 7010, storage articles with spouts or spigots for 

dispensing liquid will be classified as table/kitchen glassware in subheading 7013.49, 

not as preserving jars in heading 7010, even if these items have bail and trigger 

closures. 

The Myers case only addressed the issue of preserving jars. It did not discuss other 

products covered by heading 7010 (i.e., containers). 

Prior to the Myers case only Mason type jars were regarded as preserving jars. This 

case expanded the universe of preserving jars from one to two. Now both the Mason 

type jar and the glass storage article with a bail and trigger closure will be regarded as 

preserving jars. 

The Myers decision is often referred to incorrectly by importers or their representatives 

who are arguing that particular products should be classified in heading 7010. People 

often refer to this case erroneously when speaking of products that do not have bail and 

trigger closures. The Myers decision is totally irrelevant to products other than those 

glass storage articles that have bail and trigger closures. 

While Mason type jars and storage articles with bail and trigger closures will be 

regarded as preserving jars classifiable in heading 7010, other glass storage articles are 

regarded as table and kitchen glassware classifiable in subheading 7013.49, HTSUS. 

Thus, subheading 7013.49 (not heading 7010) will be applied to glass articles that 

are principally used as storage articles and have cork closures, metal closures 

13
Table and Kitchen Glassware 

March 2010 

(other than the bail and trigger type), glass closures, or other closures (which are 

different than the Mason type seal or bail and trigger closure). 

 7013.49

Glass Containers 

Glass containers provided for in heading 7010 of the HTSUS are products which are

principally used to convey and pack merchandise which will be sold 

commercially (i.e., to the consumer). 

The Myers case indicated that the reference to preserving jars in heading 7010 is to be 

regarded as an eo nomine provision, i.e., a provision which describes particular 

products by name. As stated above, the types of items regarded as preserving jars are 

Mason type jars and storage articles with bail and trigger closures. 

14
Table and Kitchen Glassware 

March 2010 

The Myers decision held that the reference to preserving jars in heading 7010 is not to 

be regarded as a principal use provision. Under Myers, we do not decide whether a 

product is classified as a preserving jar in heading 7010 based on a determination of 

whether the item is principally used as a preserving jar. 

However, the Myers case only dealt with preserving jars and is irrelevant to the question 

of whether a product is to be regarded as a container in heading 7010. Another court 

case (the Italglass decision) indicated that the reference to containers in heading 7010 

is a principal use provision. Unlike the provision for preserving jars, the provision for 

containers in heading 7010 is dependent on a determination of principal use. Note 

Group Italglass U.S.A. v. United States, 17 CIT 226 (1993). 

Principal use is defined as that use which exceeds each other single use in the 

United States for merchandise of the same class or kind as the imported product. 

The form of the article as imported is the most important criterion for determining 

class or kind which determines principal use. The actual use of the specific 

imported article is irrelevant if this does not conform to its principal use. 

Thus, even if an imported article will actually be used as a container, it cannot be 

classified as a container unless it is principally used as a container (i.e., 

principally used to convey and pack merchandise sold commercially). If it is not 

principally used as a container, it cannot be classified as a container in heading 

7010, HTSUS. 

Containers are usually disposable. Genuine containers are principally sold by importers 

to wholesalers and distributors who will pack them with goods to be marketed to 

consumers. In many instances, the importer of a container will be the one to pack the 

container with goods to be marketed to the consumers. 

Containers are principally sold to consumers filled with goods. A product will be 

regarded as a container only if its form indicates that it will be principally marketed to 

consumers filled with goods. If the form of the item does not indicate that it belongs to a 

class or kind of merchandise that will be principally used in this manner, the product 

cannot be classified as a container in heading 7010 even if the specific imported article 

will actually be used this way. 

HEADING 7010 VS. HEADING 7013 

Glass Containers vs. Glass Storage Articles 

Products that are not principally used as containers are often entered incorrectly as 

containers in heading 7010, HTSUS. 

Only glass items which will be principally used to convey and pack merchandise 

that will be sold commercially (i.e., to the consumer) may be classified as 

containers in heading 7010. On the other hand, glass storage articles principally 

15
Table and Kitchen Glassware 

March 2010 

used to store food in the home or other indoor settings will be classified as 

table/kitchen glassware in subheading 7013.49, HTSUS. The distinction which is 

made between glass storage articles (heading 7013) and glass containers (heading 

7010) based on principal use is explained in the Italglass court case cited above. 

While containers are principally sold to consumers filled with goods, glass storage 

articles are principally sold to consumers empty. 

If the form of an imported glass item indicates that it belongs to the class or kind of 

merchandise principally used as storage articles, the item is classified as table/kitchen 

glassware in subheading 7013.49, HTSUS, not as a container in heading 7010. A 

product with the form of a storage article would be classified in subheading 7013.49 

even if the item were actually used as a container since classification is based on 

principal use, not actual use. 

 

While some glass items with cork closures are regarded as containers 

classifiable in heading 7010, many (probably most) of these items are regarded as 

storage articles classifiable in subheading 7013.49. This type of article is often 

entered incorrectly as a container in heading 7010. 

Apothecary jars, cruets, cookie jars, candy jars, decanters, pasta or spaghetti 

jars, and numerous other types of glass articles principally used to store food or 

beverages in the home are classifiable as table/kitchen glassware in subheading 

7013.49. These storage articles are often entered incorrectly as containers in heading 

7010. 

While bottles principally used to convey beverages (e.g., wine) to the consumer 

are classifiable as containers, bottles that will be principally used to store 

beverages in the home are classifiable as table and kitchen glassware in 

subheading 7013.49, HTSUS. Bottles principally used as decorative articles are 

classifiable as glassware for indoor decoration in subheading 7013.99, HTSUS. 

The types of bottles classifiable in heading 7013 are often entered incorrectly as 

containers in heading 7010. 

The distinction between products principally used as containers and products principally 

used as storage articles is discussed in numerous Headquarters rulings. These rulings 

have consistently held that a glass item with a form that indicates principal use 

as a storage article is classifiable as table/kitchen glassware in subheading 

7013.49, not as a container in heading 7010. 

Note HQ rulings 959639, 10-21-97; 959941, 10-27-97; 959942, 10-27-97; 960162, 10-

17-97; 960163, 10-22-97; 959637, 12-04-97; 959751, 10-15-97; 959638, 10-10-97; and 

many more.

GLASS STOPPERS, LIDS AND OTHER CLOSURES 

Glass containers classifiable in heading 7010 of the HTSUS may be imported with or 

without their closures. In the same manner glass storage articles classifiable in 

subheading 7013.49, HTSUS, may be imported with or without their closures. 

Heading 7010 includes a provision – subheading 7010.20, HTSUS – which provides for 

glass stoppers, lids and other closures imported separately. When a stopper, lid or 

other closure of glass is imported separately from the article which it will be used to 

close, subheading 7010.20 applies; there is no requirement that the closure be used to 

cover a preserving jar or container of heading 7010. 

The closure could be intended for any type of article (including items of heading 7013 or 

items classifiable in other parts of the HTSUS). As long as the closure itself is made of 

17

glass and is not imported with the article which it will be used to close, subheading 

7010.20 is applicable. 

Note Commercial Aluminum Cookware v. United States, 20 CIT 1007, 938 F.Supp. 875 

(1996). 

GLASS VS. METAL 

Glass storage articles with metal stands, glass plates on metal racks and glass 

storage articles with metal lids or stoppers are often entered incorrectly as 

articles of metal. They are properly classifiable as glassware in heading 7013, 

HTSUS. 

Under General Rule of Interpretation (3)(b) of the HTSUS [GRI (3)(b)], the essential 

character of a glass storage article on a metal stand is generally represented by the 

glass storage article, not the metal stand. Under GRI (3)(b), the essential character of a 

glass storage article with a metal lid or closure is generally represented by the glass 

body, not the metal lid. Consequently these products are correctly classifiable as 

table/kitchen glassware in subheading 7013.49, HTSUS, not as articles of metal. 

In the same manner, glass plates or other table/kitchen glassware on metal racks, 

stands or bases are classifiable as table/kitchen glassware in subheading 7013.49, not 

as articles of metal.

26-97; 961039; 07-01-98. 

THE IMPORTER’S RESPONSIBILITIES 

Since the enactment of the Customs Modernization Act in December 1993, the legal 

burden of correctly classifying merchandise has shifted from U.S. Customs to the 

importer, who must use reasonable care in carrying out this responsibility. Prior to 

importation, the importer of record is responsible for determining the nature, size, 

material composition, principal use and unit value of the merchandise in question. 

The importer of table/kitchen glassware should be aware of the distinctions between the 

various subheadings of heading 7013 that are based on unit value. The importer must 

understand that the value referred to in these subheadings is the value of a single glass 

article. Merchandise should not be entered under a subheading based on the value of 

several glass articles packed together. 

An importer of glass articles who intends to claim that the merchandise consists of lead 

crystal must verify that the articles contain at least 24 percent lead monoxide by weight. 

Anyone who wishes to claim that merchandise consists of pressed and toughened 

(specially tempered) glassware should verify that the product meets the tests for 

18
Table and Kitchen Glassware 

March 2010 

specially tempered glass explained earlier in this publication (see the section entitled 

Specially Tempered Glassware). 

Importers of glassware should understand the distinction between products classifiable 

in heading 7010 and products classifiable in heading 7013. Glass preserving jars 

classifiable in heading 7010 are limited to Mason type jars with self-sealing lids and 

glass storage articles with bail and trigger closures. Glass containers classifiable in 

heading 7010 are limited to items principally used to pack and convey merchandise for 

sale to consumers. Glass items principally used to store food in the home or other 

indoor contexts are regarded as storage articles classifiable as table/kitchen glassware 

in subheading 7013.49, HTSUS. Importers of this type of merchandise should be 

careful not to enter subheading 7013.49 items incorrectly in heading 7010. 

The importer should understand the concept of principal use - i.e., that use which 

exceeds each other single use in the United States for merchandise of the same class 

or kind as the imported product. The form of the article as imported determines its class 

or kind, which determines its principal use. The shape and the size of an imported 

article are both factors that contribute to the definition of its form. The importer should 

understand that the actual use of the imported article might not be the same as its 

principal use. If the form of an imported article indicates that it belongs to a class or 

kind of merchandise principally used as storage articles, the product must be classified 

as table/kitchen glassware in subheading 7013.49. It should not be classified as a 

container in heading 7010 even if it is actually used as a container, since classification 

is determined based on principal use, not actual use. 

It may be helpful for the importer to submit marketing and advertising literature 

indicating how the merchandise will be marketed and used. However, the importer 

should understand that this information might not be the deciding factor in any 

determination regarding classification. Although the information will assist U.S. 

Customs in its analysis, classification is based on principal use, not actual use. The 

form of the article as imported will ultimately be more significant in the determination of 

principal use than advertising or marketing material that simply documents actual use. 

The importer should remember that glass storage articles on metal stands, glass plates 

on metal racks and glass storage articles with metal lids or stoppers are classifiable as 

glassware in heading 7013. These products should not be entered as articles of metal. 

Prior to the importation of a particular glass article, an importer or a foreign supplier who 

wishes to verify the classification of the product may request a binding ruling from U.S. 

Customs. See Part 177 of the Customs Regulations (19 CFR 177). A ruling request 

should include a sample of the item as well as information on its use and precise 

composition. 

The request should indicate the unit value at which the glass article will be sold by the 

foreign seller to the American importer. If the inquirer believes that the product consists 

of a special type of glass (e.g., specially tempered glassware, lead crystal glassware or 

19
Table and Kitchen Glassware 

March 2010 

glass-ceramics), the ruling request should include a statement indicating this belief. 

The ruling request should state the brand name or style number of the glass article, the 

country of origin and the port at which the product will be imported. 

If a prospective importer or foreign supplier of a specific glass article is uncertain about 

any of the classification issues discussed in this publication, a request for a tariff 

classification ruling on this product may be sent to U.S. Customs prior to importation. 

Thus, if an importer or foreign supplier is uncertain whether a specific glass article is a 

container classifiable in heading 7010 or a storage article classifiable in subheading 

7013.49, a request for a binding ruling may be sent to U.S. Customs prior to 

importation. Similarly, if an importer or foreign supplier wishes to verify whether a 

specific product consists of a special type of glass (e.g., specially tempered glassware, 

lead crystal glassware or glass-ceramics), a ruling request may be sent to U.S. 

Customs prior to importation. In the same manner, any other classification question 

raised by a specific glass article can be addressed in a ruling if an importer or foreign 

supplier sends a request to U.S. Customs prior to importation. 

INVOICING REQUIREMENTS 

In accordance with Section 141.86 of the Customs Regulations (19 CFR 141.86), 

invoices should describe the precise nature and use of the merchandise. Each 

component material of the article should be identified. 

The precise form of the article should be described (e.g., drinking glass, decanter, 

pitcher, bowl, plate, cruet, apothecary jar, glass storage article with cork stopper, etc.). 

The height of the product should be indicated. For articles that will be used to hold food 

or beverages, the invoice should indicate depth and capacity (volume). 

The invoice should indicate the unit value at which the article is sold by the foreign firm 

to the American importer, the quantity of the merchandise imported and the total value 

of this merchandise. 

The importer must remember that the applicable eight digit subheading for most 

products classifiable in heading 7013 is dependent on the unit value of a single glass 

article. The invoice should indicate the unit value of a single article, not the value of 

several items packed together. 

If the article is made of a special type of glass (e.g., specially tempered glassware, lead 

crystal glassware or glass ceramics), the invoice should state this information. A 

product should be invoiced as pressed and toughened (specially tempered) only if it 

meets the standards described above in the section entitled Specially Tempered 

Glassware. A product should be invoiced as lead crystal glassware only if it contains at 

least 24 percent lead monoxide by weight.

Importing into the United States 

This publication provides an overview of the importing process and contains general 

information about import requirements. The current edition of Importing Into the United 

States contains much new and revised material brought about pursuant to the Customs 

Modernization Act (“Mod Act”). The Mod Act has fundamentally altered the relationship

the legal responsibility for declaring the value, classification, and rate of duty applicable 

to entered merchandise. 

The current edition contains a section entitled "Informed Compliance." A key component 

of informed compliance is the shared responsibility between U.S. Customs and Border 

Protection and the import community, wherein CBP communicates its requirements to 

the importer, and the importer, in turn, uses reasonable care to assure that CBP is 

provided accurate and timely data pertaining to his or her importation.
