1. PURPOSE

This directive establishes uniform procedures for the factor analysis of safflower seed 

under the Agricultural Marketing Act of 1946, as amended (AMA)

2. REPLACEMENT HIGHLIGHTS

This directive is revised to specify that any moisture meter listed as approved in 

the Moisture Handbook can be used to determine moisture content. This directive

supersedes FGIS Program Directive 9180.53, “Inspection of Safflower Seed”, dated 

5/01/13

3. GENERAL INFORMATION

There are no classes, subclasses, or grades for safflower seed. The inspection of 

safflower seed is performed on a factor-only basis. The factors analyzed are: kind of 

grain, infestation, heating, odor, animal filth, glass, unknown foreign substances, other 

grains, moisture, dockage, damaged kernels (total), other-damaged kernels, heatdamaged kernels, sprout-damaged kernels, stones, oil content, free fatty acid level, and 

iodine value

The AMA regulations provide for three inspection service levels

For all analytical tests, as outlined in section 17 of this directive, the following three 

inspection service levels apply: original, retest, and appeal.

For all other factors, the following inspection service levels apply: original, appeal, and 

Board appeal

a. Retests. Official personnel shall perform only one retest inspection service on

any original inspection. An applicant may request one retest of any one or more

quality factors included in the original inspection. Quality factors included in the

original inspection but not included in the retest request may not be retested at a 

later date

b. Appeals. Official personnel shall perform only one appeal inspection on an

original or retest inspection service. An applicant may request an appeal inspection

on (1) any of the kinds of inspection services performed for an original inspection, 

or (2) a retest inspection. For appeal inspections, the field office must analyze the 

sample for all of the quality factors included in the original inspection

For appeals of analytical factors, however, the Quality Systems and Services Unit 

(QSS) must perform the analyses

c. Board Appeal. An applicant who is dissatisfied with the original or the appeal

inspection results may appeal to the FGIS Board of Appeals and Review (BAR). 

The Board appeal shall be limited to an analysis of the file sample. When a request 

for a Board appeal inspection is filed, the file sample(s) and all other pertinent 

information shall be immediately submitted to the BAR. The field office shall act as 

a liaison between the BAR and the applicant.

7. DEFINITION OF SAFFLOWER SEED

Safflower seed (Carthamus tinctorius) shall consist of 50.0 percent or more of whole or 

broken safflower seed before the removal of dockage.

A hull alone does not constitute a safflower seed.

According to the following definition, a safflower seed can be either a combination of the 

hull and kernel (the size of either is irrelevant as long as they are connected) or just the 

kernel with no hull attached.

Basis of Determination. Normally, a visual appraisal of the sample is sufficient 

to determine if it meets the definition of safflower seed. However, if an analysis is 

necessary, make the determination before the removal of the dockage on a portion of 

approximately 60 grams

The following definitions apply when identifying safflower seed:

a. Hull (husk). The ovary wall of the safflower seed

b. Kernel (meat). The interior contents of the safflower seed which are surrounded by

the hull

c. Whole seed. The term whole safflower seed includes seeds and broken seeds

with kernels. Seeds that do not contain kernels will not be considered as being 

whole safflower seeds.

8. INFESTATION

Infestation refers to safflower seed that is infested with live weevils or other live insects 

injurious to stored grain according to procedures prescribed in FGIS instructions

The presence of any live weevil or other live insect injurious to stored grain indicates the 

probability of infestation and warns that the safflower seed must be carefully examined 

to determine if it is infested. In such cases, examine the work sample and the file 

sample before reaching a conclusion about whether the safflower seed is infested. Do 

not examine the file sample if the work portion is insect free.

Live weevils shall include rice weevils, granary weevils, and lesser grain borers. Other 

live insects injurious to stored grain shall include grain beetles, grain moths, meal 

worms, vetch bruchids, and larvae. (See Grain Inspection Handbook, Book II, Chapter 

1, General Information, Section 1.2, Visual Grading Aids

Basis of Determination. Determine infestation on the lot as a whole and/or the sample 

as a whole (1-1/8 to 1-1/4 quarts or an equivalent number of grams). For specific 

guidelines, see table No. 2 and Grain Inspection Handbook, Book I, Grain Samplin
FGIS Directive 9180.53 March 14, 2022

III. Online Sample (In-Motion) 2

- Railcars Under Cu-Sum

- Subsamples for Sacked Grain Lots

- Components for Bargelots 3

- Components for Shiplots 3

1

 Examine work portion and file sample if necessary. Do not examine file sample if work portion is insect free.

2

 Minimum sampling rate is 500 grams per 2,000 bushels. 

 Minimum component size is 10,000 bushels.

Key: lw = live weevil oli = other live insects injurious to stored grain

Certification. When applicable, record the word “Infested” on the work record and the 

certificate.

9. HEATING

Seed developing a high temperature from excessive respiration is considered heating

Heating seed in its final states usually produces a sour or musty odor. Care should be 

taken not to confuse seed that is heating with seed that is warm and moist because of 

storage in bins, railcars, or other containers during hot weather.

Basis of Determination. Determine heating on evidence obtained at the time of

sampling

Certification. When applicable, record the word “Heating” on the work record and 

certificate.

10. ODOR

Basis of Determination. Determine odor on evidence obtained at the time of sampling,

on the sample either before or after the removal of dockage. Odors detected at the time

of sampling must be recorded on the work record.

However, the final determination for odor must be performed in the laboratory.
FGIS Directive 9180.53 March 14, 2022

Skunk

Smoke (evidence of fire- burnt material)

Strong weed

* Consider smoke odors as sour unless there is evidence of fire-burnt material.

Commercially Objectionable Foreign Odors. Commercially objectionable foreign odors

are odors that are entirely foreign to safflower seed that render the seed unfit for normal 

commercial usage

Fumigant or insecticide odors are considered commercially objectionable foreign odors 

if they linger and do not dissipate. When a sample of safflower seed contains a fumigant 

or insecticide odor that prevents a determination as to whether any other odor(s) exists, 

apply the following guidelines:

a. Original Inspections. Allow the work portion to aerate in an open container for

4 hours, or less, if the odor dissipates in less time

b. Reinspections, Appeal, and Board Appeal Inspections. Allow unworked file sample

and new samples to aerate in an open container for a period not to exceed 4 

hours. Do not aerate file samples (unworked files) which were previously aerated 

and retained as the final file.

Consider the sample as having a commercially objectionable foreign odor if the fumigant 

or insecticide odor persists based on the above criteria

Certification. If present, record the words “Musty,” “Sour,” or “Commercially 

Objectionable Foreign Odor” on the work record and the certificate.

11. ANIMAL FILTH, GLASS, AND UNKNOWN FOREIGN SUBSTANCES

Basis of Determination. Determine animal filth, glass, and unknown foreign 

substances on the basis of the sample as a whole (1-1/8 to 1-1/4 quarts).

Certification. Record the number of pieces of animal filth, glass, and unknown foreign 

substances on the work record and the certificate.
FGIS Directive 9180.53 March 14, 2022

Page 7

12. OTHER GRAINS

Other grains are wheat, barley, oats, corn, sorghum, rye, and triticale.

Basis of Determination. Determine other grains on a representative portion of 

approximately 30 grams cut from the original sample

Certification. Record the percentage of other grains on the work record and certificate 

to the nearest one-tenth percent.

13. MOISTURE

Moisture is the water content of safflower seed as determined by approved moisture 

instruments listed in the Moisture Handbook using the approved calibration (see FGIS 

Directive 9180.61

Basis of Determination. Determine moisture on a portion of approximately 400 grams

before the removal of dockage

Certification. Record the percentage of moisture on the work record and the certificate 

to the nearest one-tenth percent.

14. DOCKAGE

Dockage is all material, other than whole safflower seed that can be easily removed with 

a cleaning device and by handpicking and also includes underdeveloped, shriveled, and 

small pieces of safflower seed that cannot be recovered by properly recleaning.

Basis of Determination. Determine dockage in safflower seed on a representative 

portion of approximately 1-1/4 quarts cut from the original sample.
FGIS Directive 9180.53 March 14, 2022

Page 8

Procedure. The procedure for determining dockage is performed in two steps: (1) 

machine cleaning and (2) handpicking

STEP 1. Procedure for Determining Dockage with the Carter Dockage Teste

a. When running samples through the Carter Dockage Tester, insert the

appropriate sieves and riddles and set the air and feed controls to the 

proper position. The Carter Dockage Tester must be at zero energy 

anytime sieves are inserted or removed

Note: To accurately remove dockage from safflower seed, the 

Carter Dockage Tester must be modified in accordance with 

procedures prescribed in the attachment.

Safflower Seed

Air Feed Riddle Top Middle Bottom

* 6 8 --- 8 7

* The air setting for each Carter Dockage Tester must be standardized to provide results that agree with the master 

machine at FGIS’ National Grain Center in Kansas City, MO. Refer to procedures prescribed in the attachmen

b. Run the portion through the modified Carter Dockage Tester.

c. Examine the material that passed over the bottom sieve. If the materia

consists of 50 percent or more of whole or broken safflower seed, return 

it to the cleaned safflower seed. Otherwise, add that material to the 

dockage

Note: Return safflower seed which passed over the riddle or that is 

caught in the riddle to the cleaned portion.

d. Dockage is all material removed by aspiration; material other than

safflower seed that passed over the riddle; the material that passed 

through the bottom sieve; and the material that passed over the bottom 

sieve when such material consists of less than 50 percent safflower 

seed

STEP 2. Procedure for Determining Dockage by Handpickin

a. Cut down the cleaned sample to a portion of not less than 30 grams.

b. Handpick the 30-gram portion for any remaining dockage (i.e., all 

material other than safflower seed).

c. Total dockage now consists of all machine separated dockage and 

handpicked dockage
FGIS Directive 9180.53 March 14, 2022

Page 9

Computing Total Dockage. All dockage obtained by the use of the Carter Dockage

Tester shall be computed on the basis of the sample as a whole. The percentage of 

dockage removed by handpicking, determined on the basis of the weight in grams of the 

portion used for the hand separation, must be multiplied by the fractional proportion of 

safflower seed remaining after the removal of the mechanically separated dockage.

a. (Weight of dockage ÷ original sample weight) x 100 = percent of mechanically 

separated dockage

b. 100 percent - percent of mechanically separated dockage = percent cleaned 

safflower seed.

c. (Weight of handpicked separation ÷ weight of handpicked sample) x 100 = 

percent of handpicked dockage

d. (Percent cleaned safflower seed x percent handpicked dockage) x 100 = 

adjusted percentage of handpicked dockage

e. Percent of mechanically separated dockage + adjusted percentage of handpicked

dockage = percent of dockage (total).

Example:

Original sample weight 990.00 grams

Weight of mechanically separated dockage 101.50 gram

Weight of handpicked portion 30.36 gram

Weight of handpicked dockage 0.67 gram

a. 101.50 grams ÷ 990 grams = 0.102 x 100 = 10.20% mechanically separated dockage

b. 100% - 10.20%) = 89.80% cleaned safflower seed.

c. (0.67 grams ÷ 30.36) = 0.022 x 100 = 2.20% handpicked dockage.

d. (89.80% x 2.20%) x 100 = 1.97% adjusted percentage of handpicked dockage.

e. 10.20% + 1.97% = 12.17% dockage (total) (add in hundredths, round to 12.2%).

Certification. Record the percentage of dockage (total) on the work record and 

certificate to the nearest one-tenth percent.
FGIS Directive 9180.53 March 14, 2022

Page 10

15. DAMAGED KERNELS

Damage must be distinct. In general, a safflower seed shall be considered damaged 

when the damage is distinctly apparent and of such character as to be recognized as 

damaged for commercial purposes

a. Damaged Safflower Seed. Kernels and pieces of kernels of safflower seed that are

damaged by blight and/or mold, heat-damaged, sprout-damaged, frosted, badly 

ground-damaged, badly weather-damaged, weevil-bored, or otherwise materially 

damaged

b. Heat-Damaged Kernels. Kernels and pieces of kernels of safflower seed that have

been materially discolored and damaged by heat

c. Frosted. Kernels and pieces of kernels of safflower seed that are badly shrunken

and distinctly discolored black or brown by frost.

Basis of Determination. Determine damaged kernels on a representative portion of

not less than 30 grams cut from the work sample after the removal of mechanically 

separated dockage

Procedure. Refer to the visual reference images when handpicking for damaged 

kernels. Reference Image: Safflower Damage (ILP: SAF-1.0 Badly Ground and/or 

Weathered and ILP: SAF-2.0 Sprout Damage).

Note: For the determination of heat-damaged kernels, the kernels often need to be 

cross-sectioned to determine the extent of damage. Safflower seed kernels that 

are heat-damaged usually have a dull dead appearance and are discolored brown 

or black. The oil-bearing portion of the seed is brown or black and has a mealy 

consistency with little or no oil content.

To compute damaged kernels (total), add the percentage of heat-damaged, sproutdamaged, and other-damaged kernels of safflower seed.

Proceed as follows:

a. (Weight of other-damaged kernels ÷ weight of representative portion after the 

removal of dockage) x 100 = percent of other-damaged kernels.

b. (Weight of heat-damaged kernels ÷ weight of representative portion) x 100 = 

percent of heat-damaged kernels.

c. (Weight of sprout-damaged kernels ÷ weight of representative portion) x 100 = 

percent of sprout-damaged kernels.

d. Percent of other-damaged kernels + percent of heat-damaged kernels + percent of 

sprout-damaged kernels = percent of damaged kernels (total).
FGIS Directive 9180.53 March 14, 2022

Page 11

Example:

Weight of representative portion 30.04 gram

Weight of other-damaged kernels 0.07 grams

Weight of heat-damaged kernels 0.10 grams

Weight of sprout-damaged kernels 0.12 grams

a. 0.07 grams ÷ 30.04 grams) = 0.002 x 100 = 0.20 percent of other-damaged kernels

b (0.10 grams ÷ 30.04 grams) = 0.003 x 100 = 0.30 percent of heat-damaged kernels

c. 0.12 grams ÷ 30.04 grams) = 0.003 x 100 = 0.30 percent of sprout-damaged kerne

d. 0.20% + 0.30% + 0.30% = 0.80 percent of damaged kernels (total) 

(add in hundredths and round to 0.8%)

Certification. Record the percentage of damaged (total), other-damaged, heatdamaged, sprout-damaged kernels on the work record and certificate to the nearest 

one-tenth percent.

16. STONES

Stones are concreted earthy or mineral matter and other substances of similar hardness 

that do not disintegrate in water.

Basis of Determination. Determine stones on a representative portion of approximately

1-1/8 to 1-1/4 quarts after the removal of dockage (as removed by the Carter Dockage 

Tester)

Certification. Record the number of stones and percentage of stones by weight (to the 

nearest one-tenth percent) on the work record and certificate.

17. OIL, FREE FATTY ACID, AND IODINE VALUE

a. General. FGIS will test safflower seed at QSS for its iodine value, oil content, and

free fatty acid level. Persons interested in receiving these services may contact

QSS directly or may request service through their local field office. Application 

forms may be obtained from any FGIS field office.

b. Kind of Services. Upon request, QSS will provide oil, free fatty acid, and/or iodine

value analyses on all submitted and official samples. A retest analysis is based 

on the official file sample. Only one retest inspection service may be performed 

on any original inspection service. An appeal analysis is based on the official file 

sample or a new sample. An appeal inspection shall be based on a new sample 

only if the lot can be positively identified by official personnel as the one that was 

inspected previously and the entire lot is available and accessible for sampling and 

inspection
FGIS Directive 9180.53 March 14, 2022

Page 12

(1) Submitted Sample Inspection Service. A submitted sample is a sample,

other than an official sample, submitted by or for an interested person for 

official inspection. A minimum 50-gram sample is required for each analysis 

(i.e., 50 grams must be submitted for an oil analysis but 150 grams must b

submitted for an oil, free fatty acid, and iodine value analyses)

(2) Quality Inspection Service. A quality inspection service involves official 

personnel obtaining a sample from an identified lot and forwarding a 

representative portion to QSS for analysis. A minimum 50-gram sample 

is required for each analysis (i.e., 50 grams must be submitted for an oi

analysis but 150 grams must be submitted for an oil, free fatty acid, and 

iodine value analyses). An official sample(s) being mailed or shipped via 

courier service by an applicant must be sealed (i.e., numbered seal or lea

wire seals) in order to maintain its identity.

c. General Procedures. For quality inspection service, official personnel shall sample

according to the guidelines in Book I of the Grain Inspection Handbook. A minimum

50-gram sample is required for each analysis (i.e., 50 grams must be submitted 

for an oil analysis but 150 grams must be submitted for an oil, free fatty acid, and 

iodine value analyses)

QSS shall maintain a file sample (balance of the representative portion after 

testing) on each original, retest, and appeal inspection service

d. Test Procedure. QSS uses a modified solvent extraction procedure (A.O.C.S.

Official Method) in the determination of oil content and A.O.C.S. Official Methods in 

the determination of free fatty acid levels and iodine values. Samples are analyzed 

2 or 3 business days after QSS receives the sample. Results are reported

immediately to the appropriate FGIS field office after analyses are recorded by 

QSS (see Certification and Billing).

e. Certification and Billing. For all oil, free fatty acid, and iodine value testing service

performed by QSS, the field office nearest the location where the request 

originated shall issue the applicable certificate(s) based on the results from QSS 

and complete the billing. Testing fees will be assessed in accordance with Section 

868.90 of the AMA regulation

The appropriate field office will show the oil content, free fatty acid level on the work 

record and certificate to the nearest one-tenth percent. The iodine value will be shown 

to the nearest whole number.
FGIS Directive 9180.53 March 14, 2022

Page 13

18. CERTIFICATION

The analysis of safflower seed shall be certified on a commodity inspection certificate. 

A commodity submitted sample certificate must be issued for a sample submitted by an 

applicant or an agent

When an applicant requests analysis for only specific factors, record the following 

sentence on the certificate:

“Specific factor analysis only.”

SAFFLOWER SEED MODIFICATION PROCEDURE

FOR CARTER DOCKAGE TESTER

The following information explains the modification procedure to be used to convert a 

dockage tester for use with safflower seed, in addition to grain. Figures 1 and 2 show 

the machine before and after modification, and the step-by-step procedure is shown 

in Figure 3. [NOTE: The “Con- trol” (Ctrl) end of the fan shaft is the end facing the side 

of the tester where the Feed and Air adjustment knobs are located. The “Non-Control” 

(Non-Ctrl) end faces toward the link-type V-belt.]

Figure 1

Figure 2
FGIS Directive 9180.53 March 14, 2022

Page 15

After modification, the machine’s aspiration process is changed when the tester is 

configured for safflowers, which require increased aspiration. This is accomplished by 

moving the belts from sheave-to-sheave to change the machine settings between grain 

and safflower seed. However, the grain settings will not be altered when the dockage 

tester is configured for grain.

MODIFICATION PROCEDURES

MATERIALS: Sheaves (Pulleys): 2VP36x5/8 (for motor shaft)

AC45x3/4--AC40x3/4, welded

(for fan shaft-Ctrl side)

Belt, linked V-belt, 69-inch

EQUIPMENT: RPM counter (low speed)

Strobelight-type RPM counter (high speed)

Tools (screwdriver, pliers, allen wrenches, etc.)

DOCKAGE TESTER CHECK:

Check camshaft RPM; if necessary, adjust machine to obtain a camshaft speed of 

146-148 RPM. (See FGIS Equipment Handbook, Chapter 4.)

Check the fan shaft RPM. [NOTE: This speed may range from 918 (XT#) to 1070 

RPM (XT1), depending on the tester model.] Record this speed.

Unplug machine and remove top cover and belt guard

Remove V-belt A31, V-belt (link-type), and original sheaves from motor shaft and 

fan shaft (both ends)

Install new sheaves and belt according to the following procedure.
FGIS Directive 9180.53 March 14, 2022

Page 16

Fig. 3 STEP-BY-STEP PROCEDURE

STEP 1: Install sheaves on motor and fan shafts, V-belt A31 on motor-to-fan link, and 

the 69-inch link-type V-belt on the fan-to-camshaft link. See Fig. 2 above for 

location of sheaves. Line up the matching sheaves as parallel as possible

with the belt’s route of travel.

STEP 2: Adjust inside motor sheave to achieve the original fan shaft (Ctrl) RPM speed 

(before modif.). Adjust inside fan shaft sheave (Non-ctrl) to achieve a 

camshaft speed of 146 - 148 RPM.

Figure 3

STEP 3: Adjust outer motor sheave to achieve fan speed of 1300 RPM, and adjust 

outer fan shaft sheave (Non-ctrl) to achieve cam speed of 146 - 148 RPM.

All modified FGIS dockage testers shall be tested and calibrated against the 

designated Headquarters Standard machine located at the FGIS National 

Grain Center in Kansas City

Note: Whenever belt guards have been removed, they must be returned 

to position prior to machine start up.
