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 "Agglomerated Stone”. 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 the Executive Director, 

Regulations and Rulings, Office of International Trade, U.S. Customs and Border Protection,

INTRODUCTION 

Heading 6810 of the Harmonized Tariff Schedule of the United States (HTSUS) covers 

both articles of artificial stone and articles of concrete or cement. This Informed 

Compliance Publication will focus on the articles of artificial stone – more commonly 

referred to as agglomerated stone – provided for in heading 6810. 

This type of merchandise has become very significant. In recent years, many articles of 

agglomerated stone classifiable in heading 6810 have been imported into the United 

States. In addition, products that are not properly classifiable in heading 6810 are often 

entered incorrectly in this provision. 

Therefore, importers who believe that their merchandise may include articles of 

“agglomerated stone” should have a clear understanding of the definition of this term. 

They should understand the precise nature of the merchandise that is classified as 

“artificial stone” in heading 6810. They should also have a clear understanding of the 

types of products that do not meet the definition of artificial stone but are often entered 

incorrectly as artificial stone in heading 6810. 

DEFINITION OF AGGLOMERATED STONE 

Agglomerated stone classifiable in heading 6810 consists of natural stone uniformly 

bound or agglomerated with a binding material.

July 26, 1993; 887033, August 9, 1993; E85426, August 20, 1999; and many others. 

The binding material in an agglomerated stone product can be plastics, cement, lime, 

etc. The stone can be in the form of pieces, chunks, pebbles, powder, etc. 

 An article is regarded as “agglomerated” when both components - binder and stone - 

run together throughout the body of the article. If one cuts into a product that is truly 

agglomerated stone at any point in the body of the article, one would consistently find 

both components blended together. 

 On the other hand, if one section of a product consists of plastics while another distinct 

section consists of stone, this item would not be regarded as agglomerated stone. In 

this example, the merchandise cannot be defined as agglomerated stone because the 

7
Agglomerated Stone 

March 2009 

natural stone and the binding material do not run together throughout the body of the 

article. When we classify this type of product with distinct plastic and stone components 

(which are not blended together), we are dealing with a composite good classifiable 

based on the guidelines of General Rule of Interpretation (3) [GRI (3)], not 

agglomerated stone classifiable in heading 6810. Under GRI (3), composite goods are 

classified under the provision applicable to the component that imparts the essential 

character to the product or - if no single component imparts essential character - under 

the provision that appears last in the HTSUS. Thus, when GRI (3) is applied, a product 

with separate stone and plastic sections will be classified either in heading 6802 as 

building stone or in Chapter 39 as plastics, not as agglomerated stone in heading 6810. 

 

 If an article consists of different types of natural stone attached to each other with 

binding material and forming a pattern, this conglomerated stone item could not be 

regarded as agglomerated stone, because the stone and the binding material are not 

blended together throughout the body of the article. This type of article will be classified 

as building stone in heading 6802, not as agglomerated stone in heading 6810. (When 

we classify an article consisting of different types of stone attached to each other, the 

applicable subheading under heading 6802 will be determined based on the application 

of GRI (3).) 

The provision for artificial stone in heading 6810 can only be applied to a product when 

natural stone and a binding material (e.g., plastic resin, cement or lime) are uniformly 

agglomerated together throughout the body of the article. 

THE ARTICLES OF AGGLOMERATED STONE COVERED BY HEADING 

6810 SHOULD NOT BE CONFUSED WITH DIFFERENT TYPES OF 

ARTICLES PROVIDED FOR IN OTHER HEADINGS 

 The agglomerated stone products classifiable in heading 6810 (“artificial stone”) should 

not be confused with the worked natural (i.e., unagglomerated) monumental/building 

stone classifiable in heading 6802. 

 In addition, the agglomerated stone articles classifiable in heading 6810 should not be 

confused with the articles of worked vegetable or mineral carving material classifiable in 

heading 9602. These products of heading 9602 include articles of vegetable materials 

of a kind used for carving. They also include articles of mineral carving material 

including amber, meerschaum, agglomerated amber, agglomerated meerschaum, jet 

and mineral substitutes for jet. Articles of agglomerated amber, articles of 

agglomerated meerschaum and other products covered by heading 9602 should not be 

entered as articles of agglomerated stone in heading 6810.

STONE MATERIAL IN AGGLOMERATED STONE MUST BE NATURAL 

STONE 

The provision for artificial stone products in heading 6810 covers articles of 

agglomerated stone, not simply articles of any agglomerated material. 

A product consisting of agglomerated material can be classified as artificial stone in 

heading 6810 only if this material is natural stone. If the agglomerated material is a 

synthetic chemical or a mineral other than stone, heading 6810 would not apply. 

A synthetic chemical combined with plastics would be classified as plastics in Chapter 

39, not as agglomerated stone in heading 6810. This scenario is not uncommon. 

Products classifiable in Chapter 39 are often entered incorrectly in heading 6810. 

For an example of this situation, see NY ruling 889036, dated August 26, 1993. This 

ruling covered various articles - counter sheets, kitchen sinks, vanity tops and lavatory 

bowls – consisting of plastics combined with a synthetic chemical. The merchandise 

was classified as plastics in various headings of Chapter 39, not as agglomerated stone 

in heading 6810. 

A mineral material (other than stone) combined with plastics would be classified as 

plastics in Chapter 39 if the plastics imparted the essential character to the product, or 

as articles of other mineral substances in heading 6815 if the mineral material imparted 

the essential character to the product. (Other Chapter 68 provisions could apply 

depending on the precise mineral present in the product.) 

DERIVATION OF PURPORTED STONE MATERIAL MUST BE VERIFIED 

Since the agglomerated material in products classifiable as artificial stone in heading 

6810 must be natural stone, verification of the precise derivation of this material 

becomes crucial. Information from the producer on the exact nature of the material is 

necessary. 

Even if an article consists of an agglomerated material that is chemically identical to a 

specific stone, the article will not be regarded as agglomerated stone unless the 

material is physically in the form of stone. The agglomerated material must meet the 

geological definition of stone. Therefore, it is clearly not sufficient for the producer to 

indicate merely the chemical name of the purported stone material in an agglomerated 

product. We require information confirming that this material is in fact natural stone. 

Products that are purported to consist of agglomerated stone are often described as 

“calcium carbonate” or “calcite” agglomerated with plastics material. Since 

agglomerated stone classifiable in heading 6810 must consist of natural stone

agglomerated with binding materials, the term “calcium carbonate” alone does not tell 

us whether the product is agglomerated stone. 

9
Agglomerated Stone 

March 2009 

Calcium carbonate or calcite can be in the form of granules, pebbles, chunks or powder 

of natural stone such as marble or limestone. When calcium carbonate in the form of 

limestone, marble or another natural stone is uniformly agglomerated with a binding 

material such as plastics or cement, the agglomerated product may be classified as 

artificial stone in heading 6810. 

However, calcium carbonate can also be in the form of a synthetic chemical or a mineral 

other than stone. When this is the case, the agglomerated calcium carbonate will not 

be classified in heading 6810, because the product does not contain natural stone. 

(See section above entitled “Stone Material in Agglomerated Stone Must Be Natural 

Stone.”) 

The merchandise should be entered in accordance with the derivation of the calcium 

carbonate. If the calcium carbonate is derived from natural stone, heading 6810 could 

be applied. 

However, if the calcium carbonate is in the form of a synthetic chemical, Chapter 39 

would be applicable to the article of synthetic calcium carbonate agglomerated with 

plastics material. Since the product does not contain natural stone, heading 6810 could 

not be applied in this case. 

If the calcium carbonate is in the form of a mineral other than stone (the least likely 

scenario), classification of the calcium carbonate agglomerated with plastics will be 

determined based on the component (plastics or mineral) that imparts the essential 

character to the product. Depending on the determination regarding essential 

character, a mineral (other than stone) agglomerated with plastics could be classified 

either as an article of plastics in Chapter 39 or as an article of mineral substances in 

heading 6815 (or possibly another Chapter 68 provision depending on the specific 

mineral). 

PERCENTAGE OF STONE VS. PERCENTAGE OF BINDING MATERIAL 

IN AN AGGLOMERATED ARTICLE 

A frequently asked question regarding agglomerated stone concerns the percentage of 

stone vs. the percentage of binding material in the product. In order for a product to be 

regarded as agglomerated stone classifiable in heading 6810, assuming we have 

verified that the agglomerated material is natural stone, is there a requirement that the 

stone constitute a greater percentage by weight within the product than the binding 

material? The answer is no. 

Often agglomerated stone consists of stone powder agglomerated with plastics resins. 

In this situation, the plastics material will frequently weigh more than the natural stone. 

Thus, we cannot require a greater percentage by weight for the stone material in 

agglomerated stone products. 

Stone agglomerated with plastics is classifiable in heading 6810 on the basis of General 

Rule of Interpretation (1) [GRI (1)]. Under this rule, merchandise is classified based on 

10
Agglomerated Stone 

March 2009 

the language of the HTSUS provisions and notes. Artificial stone is provided for 

specifically in the HTSUS. The unique combination of plastics and stone that comprises 

agglomerated stone is described clearly in heading 6810. This heading provides for the 

product more clearly than heading 6802 which covers unagglomerated building stone or 

the Chapter 39 provisions which cover plastics articles. 

General Rule of Interpretation (3) [GRI (3)] – the rule which addresses the classification 

of composite goods and sets that cannot be classified based on GRI (1) – is usually not 

applicable to our consideration of agglomerated stone. Since agglomerated stone is 

specifically provided for in the HTSUS, we do not regard the classification of stone 

agglomerated with plastics as a GRI (3) question. 

When we classify an agglomerated stone product, we are not seeking to find which 

component (plastics or stone) is more substantial and imparts the essential character to 

the item. As explained above, the classification of agglomerated stone is usually 

determined based on GRI (1), not GRI (3). If the stone and plastics components are 

uniformly agglomerated throughout the body of the article, the product will generally be 

regarded as agglomerated stone. This will usually be the case whether the plastic 

component or the stone component comprises a greater portion of the product’s weight. 

Nevertheless, if there is very little stone in a product that contains both plastics and 

stone, there is the possibility that the merchandise is not agglomerated stone but 

plastics containing filler. 

Floor and wall tiles of stone agglomerated with plastics usually contain substantial 

amounts of stone. In these products, the stone generally constitutes the greatest 

component of the product by weight. In these articles, the stone is generally in the form 

of heavy chunks. 

However, in figurines and other decorative articles consisting of stone agglomerated 

with plastics, the percentage (by weight) of the stone is often less than the percentage 

of plastics. In these articles the stone is frequently in the form of powder. Although the 

percentage by weight of stone in a figurine of agglomerated stone may be 50 percent or 

more, frequently this percentage is in the 30’s or 40’s. Nevertheless, as long as the 

stone component and the plastics component are uniformly blended together 

throughout the body of the figurine, the article will be regarded as agglomerated stone 

classifiable in heading 6810. This will be the case even when the stone does not 

represent a greater percentage of the figurine’s weight than the binding material. 

When a product consists of agglomerated stone, it may feel heavier than a plastics 

article. In addition, when one touches an agglomerated stone article, the product will 

often have a “stone-like” feel, as opposed to the smooth feeling we experience when we 

touch a plastics article. When an item feels light and smooth, it is more likely to be a 

plastics product classifiable in Chapter 39 than an article of artificial stone classifiable in 

heading 6810. (Of course, some items that actually consist of agglomerated stone may 

be covered with a layer of plastics or plaster above the agglomerated stone. This layer 

11
Agglomerated Stone 

March 2009 

will mask the “stone-like” feel of the agglomerated stone. In addition, some items that 

actually consist of fine stone powder agglomerated with plastics may feel relatively light 

and smooth.) 

When is there so little stone in an article purported to be “agglomerated stone” that we 

cannot regard the item as artificial stone? Although there is no absolute standard, 

generally when an article consisting of stone and plastics contains 20 percent or less of 

natural stone by weight, we will not consider the product to be agglomerated stone 

classifiable in heading 6810. Rather, we will regard the item as plastics (containing 

filler) classifiable in Chapter 39. Products containing such a low amount of stone 

generally will be very light and will not have the “stone-like” feel that often characterizes 

agglomerated stone. 

When an article consisting of stone and plastics contains between 21 and 30 percent 

natural stone by weight, the product may or may not be regarded as agglomerated 

stone. This product falls into a gray area. Depending on how heavy or light the item is 

and depending on whether or not it has a “stone-like” feel, we may regard this article 

either as agglomerated stone or plastics. 

An importer of products purported to be agglomerated stone may be asked to provide 

information from the foreign manufacturer indicating the percentage by weight of stone 

and the percentage by weight of binding material in the article. 

CONFUSING TERMINOLOGY 

There is always the possibility that plastics products classifiable in Chapter 39 and 

agglomerated stone products classifiable in heading 6810 will be confused. The use of 

confusing designations in the industry contributes to this problem. The names used in 

the trade for products purported to be agglomerated stone are frequently misleading. 

Often these names fail to clarify the true nature of the merchandise. 

The word “polyresin” is a scientific or technical term that refers to a type of plastics 

material. Generally, when this term is used in the industry (e.g., on an invoice), it refers 

to plastics material classifiable in Chapter 39. When this word is used properly, it 

should not refer to anything other than a plastics product. 

However, the word “polyresin” is often used incorrectly (e.g., on invoices) to refer to an 

agglomerated stone product - classifiable in heading 6810 - consisting of a combination 

of plastics resins (polyresin) and natural stone. Sometimes, the term “polyresin” is used 

to refer to a combination of plastics material and a synthetic chemical classifiable in 

Chapter 39. 

When one hears the word “polyresin,” one can easily assume that the merchandise is 

simply plastics, since the accepted scientific meaning of the term is a type of plastics. 

Absent specific information on the precise nature of the merchandise at issue, we have 

no way of knowing whether this term is being used properly to refer to a plastics article 

12
Agglomerated Stone 

March 2009 

or whether the word is being used to designate an article of stone agglomerated with 

plastics. Since the terminology used is often confusing, it is crucial for importers of 

articles that may consist of artificial stone to obtain clear information from their suppliers 

regarding the precise components in this merchandise. 

Of course, it would be best if products consisting of agglomerated stone were not 

referred to as “polyresin.” To whatever extent possible, it would be helpful if importers 

could advise their suppliers to limit the use of this term to plastics articles. However, as 

long as some companies continue to use the term “polyresin” for products purported to 

be agglomerated stone, it is essential that importers obtain clear information on the 

exact nature of these articles. The importer should obtain complete details from his or 

her supplier on the precise derivation of each component in any article claimed to be 

agglomerated stone as well as the percentage by weight of each component. (See 

sections above entitled “Derivation of Purported Stone Material Must Be Verified” and 

“Percentage of Stone vs. Percentage of Plastics Material in an Agglomerated Article.”) 

Another name often used in industry to refer to stone agglomerated with plastics resins 

is “polystone.” The term “polystone” - a combination of the words polyresin and stone – 

can also be confusing. This term is sometimes used to refer to products consisting of 

natural stone agglomerated with plastic binders – merchandise classifiable as artificial 

stone in heading 6810. However, the word “polystone” has also been used to refer to 

merchandise classifiable in Chapter 39 such as a wholly plastics article (or an article 

consisting of a combination of plastics and a synthetic chemical) that has been painted 

or otherwise constructed to resemble stone. Since this term may or may not refer to 

agglomerated stone, importers must obtain information from their suppliers on the 

derivation and weight of each ingredient in any product invoiced as “polystone” that is 

claimed to be agglomerated stone. 

LABORATORY ANALYSIS 

U.S. Customs and Border Protection will often send samples to our laboratory to 

confirm both the nature and percentages of the materials in products purported to 

consist of agglomerated stone. 

Since products which are not actually agglomerated stone are often entered incorrectly 

under the provision for this merchandise in heading 6810, analysis by our Customs 

laboratory to verify the composition of products entered as artificial stone is very 

significant. 

SUBHEADINGS COVERING DIFFERENT TYPES OF AGGLOMERATED 

STONE ARTICLES 

Tiles, flagstones, bricks and similar articles of agglomerated stone are provided for in 

subheadings 6810.11.00, 6810.19.12, 6810.19.14 and 6810.19.50. Thus, this group of 

subheadings (along with subheading 6810.91.00 which provides for prefabricated 

13
Agglomerated Stone 

March 2009 

structural components used in building or civil engineering) covers those agglomerated 

stone items that are used in the building industry. 

Subheading 6810.11.00 covers building blocks and bricks of agglomerated stone. 

Subheadings 6810.19.12 and 6810.19.14 cover floor and wall tiles of agglomerated 

stone. These are the only subheadings for agglomerated stone that make a distinction 

based on the nature of the binder. 

When the binding material in a floor or wall tile is other than cement (generally, plastics 

resins), the product is classifiable in subheading 6810.19.12. When the binding material 

in a floor or wall tile is cement, the product is classifiable in subheading 6810.19.14. 

While the majority of agglomerated stone floor and wall tiles probably employ plastic 

resins as binders, many of these products use cement binders. The distinction between 

subheadings 6810.19.12 and 6810.19.14 requires an importer of artificial stone floor 

and wall tiles to obtain information from the manufacturer regarding the binding material 

used in the merchandise. 

Note NY rulings I80354, April 26, 2002; I80355, April 26, 2002; I80356, April 26, 2002; 

I80361, April 26, 2002; I80363, April 30, 2002; I80364, April 26, 2002; I80365, April 26,

F82654, April 17, 2000. 

 

Subheading 6810.19.50 covers tiles, flagstones, bricks and similar articles: other. 

Subheading 6810.91.00 covers prefabricated structural components for building or civil 

engineering. 

Subheading 6810.99.00 covers other articles of agglomerated stone. 

Floor and wall tiles classifiable in subheadings 6810.19.12 and 6810.19.14 are often 

entered incorrectly in other subheadings of heading 6810. The size of a typical floor or 

wall tile is twelve inches by twelve inches, although floor and wall tiles can be as large 

as twenty-four inches by twenty-four inches. Additional U.S. Note 2 to Chapter 68 

precludes any item that is 3.2 centimeters or more in thickness from being regarded as 

a tile. 

Rectangular items of agglomerated stone that are larger than tiles are regarded as 

slabs. 

When a slab is a building component that can be regarded as a flagstone, brick or 

similar article, it is classifiable under the provision for other tiles, flagstones, bricks and 

similar articles in subheading 6810.19.50. However, when a slab is a general-purpose 

stone piece that can be used either as a countertop or as a building component, 

subheading 6810.99.00 will generally apply.

Note NY rulings I84858, October 10, 2002; L81391, March 3, 2005; L81680, March 3, 

2005. 

In addition to general-purpose stone slabs, subheading 6810.99.00 (the “basket” 

provision for articles of artificial stone) covers decorative or ornamental articles of 

agglomerated stone. This is the single largest category of agglomerated stone products 

imported into the United States. 

Subheading 6810.99.00 is the subheading of heading 6810 that is most likely to be 

applied incorrectly (e.g., plastics products classifiable in Chapter 39 are often entered 

incorrectly in this provision). 

THE IMPORTER’S RESPONSIBILITIES 

The importer should understand the definition of artificial stone. See section above 

entitled “Definition of Agglomerated Stone.” 

Plastics products of Chapter 39 and articles of agglomerated stone classifiable in 

heading 6810 should not be confused. 

Worked monumental or building stone and articles thereof of natural (i.e., 

unagglomerated) stone classifiable in heading 6802 should not be confused with articles 

of agglomerated stone classifiable as artificial stone in heading 6810. 

The importer should be prepared to provide information regarding the foreign firm (to be 

submitted to U.S. Customs and Border Protection) documenting the identity and the 

percentages by weight of the purported stone material and the binding material in a 

product claimed to be agglomerated stone and documenting the derivation of the 

purported stone component in a product claimed to be agglomerated stone. This 

information should indicate whether the material is derived from natural stone, a 

synthetic chemical or a mineral source other than stone. 

The importer should be aware of the distinctions between different types of articles 

classifiable in different subheadings of heading 6810. See section above entitled 

“Subheadings Covering Different Types of Agglomerated Stone Articles.” 

U.S. Customs and Border Protection may request precise information on the uses of 

articles of agglomerated stone imported into the United States. 

For slabs, tiles and other building components, the importer should be prepared to 

provide information on dimensions and thickness.

Prior to the importation of the merchandise, an importer may request a binding tariff 

classification ruling on the product from U.S. Customs and Border Protection. Ruling 

requests should be sent to: 

 U.S. Customs and Border Protection 

 Customs Information Exchange (CIE) 

 One Penn Plaza 10th Floor 

 New York, NY 10119 

 

 Attention: Binding Rulings Section 

A ruling request on a stone product should include information on the uses, dimensions 

and thickness of the article. When an importer believes that the product is 

agglomerated stone, the ruling request should include information on the precise 

chemical and geological names of each component, the percentage by weight of each 

component, and whether or not the components are uniformly agglomerated throughout 

the body of the article. The ruling request should indicate whether the agglomerated 

material is natural stone, a synthetic chemical or a mineral other than stone. 

If possible, a complete sample of the product should be submitted with the ruling 

request. However, if the product is very large (e.g., a very large slab), a section of the 

complete article should be submitted as a sample. This section should be at least 

twelve inches by twelve inches and should include portions of the face as well as the 

side or edge (including the corner) of the complete product. 

If a portion of the complete product is submitted as a sample, the ruling request should 

indicate the dimensions and thickness of the complete article as well as the precise 

nature and use of the complete article.

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 

between importers and U.S. Customs and Border Protection by shifting to the importer 

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. 

Single copies may be obtained from local offices of U.S. Customs and Border 

Protection, or from the Office of Public Affairs, U.S. Customs and Border Protection, 

1300 Pennsylvania Avenue NW, Washington, DC 20229. An on-line version is
