3 Terms and definitions
The following terms and definitions apply to this document.
3.1 sunflower seed
The seeds of Helianthus Linn. in the Asteraceae family.
3.2 pure kernel ratio
The proportion of sunflower kernels of sunflower seeds in the mass fraction of the
sample, of which the unsound kernels are calculated as half of their number.
NOTE: Unsound kernels refer to sunflower kernels that are damaged but still have use value, including
broken kernels, sprouted kernels, moldy kernels, injured kernels, spotted kernels, etc. Broken kernels
refer to the seeds that are flattened and damaged and their kernels are broken; sprouted kernels refer to
the seeds whose buds or radicles break through the seed coats; moldy kernels refer to the seeds whose
surfaces are moldy; injured kernels refer to the seeds that are damaged by worms and their kernels are
injured; spotted kernels refer to the seeds with diseased spots on kernels.
3.3 oil content
The proportion of the crude fat of sunflower seeds in the mass fraction (in dry basis) of
the sample.
3.4 useless material
Substances other than sunflower seeds, and sunflower seeds of no use value.
NOTE: The useless materials include throughs, inorganic impurities, and organic impurities. Throughs
refer to the material that can pass through a sieve with 3.5 mm diameter round holes; inorganic impurities
refer to minerals (such as sand, cinder, bricks and tiles, soil) and other inorganic substances; organic
impurities refer to useless sunflower seeds, heterogeneous oilseeds, grains, and other organic matter.
4 Categories
According to the use, sunflower seeds are divided into two categories: edible sunflower
seeds and sunflower seeds for oil.

It shall be carried out according to GB/T 5490.
7.2 Inspection batch
The sunflower seeds of the same type, the same origin, the same harvest year, the same
transport unit, and the same storage unit are regarded as one batch.
7.3 Grading rules
7.3.1 The pure kernel ratio and oil content shall meet the corresponding grade
requirements in Table 1 and Table 2, and other indexes shall meet the requirements of
relevant national regulations.
7.3.2 When the grading index fails to meet the requirements, it shall be downgraded to
the next grade. Products whose grading indexes reach the third grade, but other indexes
do not meet the requirements, are classified as off-grade.
8 Labeling
The product name, grade, place of origin, year of harvest, and country of production
shall be marked on the packaging or accompanying documents.
9 Packaging, storage, and transportation
9.1 Packaging
The packaging shall be clean, firm, undamaged, tightly sealed, and strong, and shall not
leak; it shall not bring pollution and abnormal smell to the product. When gunny bags
are used for packaging, the packaging shall comply with the regulations of GB/T 24904;
when plastic woven sacks are used for packaging, the packaging shall comply with the
regulations of GB/T 8946.
9.2 Storage
Sunflower seeds shall be stored in a clean, dry, rain-proof, moisture-proof, insect-proof,
rodent-proof, and odor-free warehouse, and shall not be mixed with toxic and harmful
substances that may pollute sunflower seeds or substances with high water content
during storage.
9.3 Transportation
