Chapter 10 covers cereals, including major food crops such as wheat, rye, barley, oats, maize, rice, sorghum, buckwheat, and millet. Cereals of this chapter refer to unprocessed grains, whether or not husked, but after milling, refining, or other processing they are generally classified under Chapter 11. This chapter is a core chapter in agricultural trade, involving sensitive regulation such as tariff quotas and quarantine. Heading 1002 refers specifically to rye, including seed rye and other rye. Rye is a cold-tolerant crop, mainly used for making rye bread, whisky, feed, etc. This heading covers rye grains, whether or not husked, but excludes products that have been milled into flour (classified under 1102) or further processed. The first 2 digits 10 represent Chapter 10 cereals; digits 3-4, 02, represent heading 1002 rye; digits 5-6 are subheadings used to distinguish seed from other: 1002.10 is seed rye, 1002.90 is other rye. A complete 6-digit code is e.g. 1002.10.00. Subheading division is based on use; seed rye must meet specific quarantine and variety standards. Rye is classified under 1002 rather than 1001 (wheat) or 1003 (barley) because the species is different. The scientific name of rye is Secale cereale, which has clear botanical distinctions from Triticum and Hordeum. If rye has been milled into flour, it is classified under 1102; if germinated, under 1104 or 1107; but in its raw grain state it must be classified under 1002.

Product name: The specific name of the declared commodity; it should state "rye" and indicate whether it is for seed use. Whether for seed use: Declare whether the batch of rye is intended for sowing; seed use requires a phytosanitary certificate and variety description. Origin: Fill in the country or region of origin of the rye, which must be consistent with the phytosanitary certificate. Processing state: State whether it is husked, whether it is milled, whether it is germinated, etc.; raw grain should be marked as "unprocessed". Grade: Grade according to quality indicators such as test weight, impurities, moisture, etc.; common grades are 1-5. Packaging specifications: State the packaging method (bags, bulk) and the net weight per package, such as "50 kg/bag". Use: State the final use of the rye, such as food, feed, brewing, industrial use, etc. Product name: rye; Whether for seed use: not for seed use; Origin: Russia; Processing state: unhusked, unmilled; Grade: Grade 2; Packaging specifications: bulk; Use: food. Confusing seed use with non-seed use; seed rye requires additional quarantine approval and variety certification. Mistakenly classifying rye flour under 1002, when it should actually be classified under 1102; tax rates and regulatory conditions differ. False declaration of origin may affect tariff preferences or trigger anti-dumping measures.

The core basis for classification is the notes to Chapter 10 and subheading notes of the Import and Export Tariff. Rye must be unprocessed grain, whether or not husked. If it has been milled, refined, germinated, or otherwise processed, it falls outside the scope of 1002. At the same time, the heading text and Harmonized System notes must be checked to ensure the species is rye (Secale cereale). 1001 Wheat and meslin: Triticum plants, a different genus from rye. Rye ears are slender, wheat ears are thicker, and rye is more cold-tolerant. 1003 Barley: Hordeum plants; the grains usually have long awns, while rye has no awns or short awns. Barley is mostly used for brewing and feed, rye mostly for bread. 1102 Other cereal flours: Rye that has been milled into flour is classified under 1102; 1002 is limited to unprocessed grains. Flour products have different tax rates and regulation. 1104 Other worked grains: Rye that has been husked, rolled, flaked, etc. is classified under 1104, such as rye flakes. 1002 is limited to simple husking. 1005 Maize (corn): Zea mays plants; the grains are larger, while rye grains are slender. Maize is mostly used for feed and industry, rye mostly for food. Confirm the commodity is rye grain, not wheat or barley. Confirm it has not been milled, refined, germinated, or otherwise processed. Confirm whether it is for seed use; seed use requires a phytosanitary certificate. Check whether the origin is subject to anti-dumping or quota restrictions. Check whether packaging and grade are consistent with the contract.

Are rye and triticale the same HS code? No. Triticale is a hybrid of wheat and rye and is usually classified as wheat under 1001. Pure rye is classified under 1002. It must be determined based on the scientific name and phytosanitary certificate. What additional documents are required for importing seed rye? Seed rye requires an official phytosanitary certificate from the exporting country, variety approval certificate, import seed approval form, etc. Non-seed rye only requires a regular phytosanitary certificate. Can rye flour be classified under 1002? No. Rye flour is a milled processed product and should be classified under 1102. 1002 applies only to unprocessed rye grain, whether or not husked. How can I check the import tariff rate for rye? You can consult the Import and Export Tariff of the People's Republic of China or the website of the General Administration of Customs, and determine the MFN rate, agreement rate, or general rate according to the country of origin. Pay attention to tariff quota conditions. Is there a tariff quota for rye imports? China applies tariff quotas to wheat, maize, rice, etc. Rye currently has no global quota, but attention should be paid to whether there are temporary safeguard measures or anti-dumping duties. How should the "grade" be filled in among the declaration elements for rye? The grade should be filled in according to national standards or contractual agreement, such as indicators for test weight, impurities, moisture, etc. Common grades are 1-5 and must be consistent with the quality inspection report. Can rye be used for feed? Yes. When declaring feed-use rye, fill in "feed" in the use column, but it must comply with feed ingredient standards. If moldy or deteriorated, import is prohibited. What inspection and quarantine procedures are required for rye imports? An import animal and plant quarantine permit must be obtained, a phytosanitary certificate must be provided, and customs inspection must be accepted. Key attention should be paid to whether it carries quarantine pests.
