Chapter 23 covers residues and waste from the food industry and prepared animal feed, with the core being "raw materials for animal feed not directly for human consumption." This chapter includes oilseed cakes and meals after oil extraction, cereal processing by-products, meat and bone meal, etc., but excludes food directly edible or prepared and shaped feed in retail packaging. Heading 2306 specifically refers to oilseed cakes and other solid residues remaining after oil extraction, which are important raw materials for the feed industry. Heading 2306 includes oilseed or oleaginous fruit cakes and other solid residues resulting from the extraction of vegetable oils, whether or not ground or in the form of pellets. Common examples include soybean meal, cottonseed meal, rapeseed meal, linseed meal, etc. However, this heading does not include: prepared animal feed (2309), single oilseed flour after oil extraction if other substances have been added, and flour of oleaginous seeds (such as linseed flour, which is classified in Chapter 12 if not oil-extracted). Code 230620 is a six-digit subheading. The first two digits "23" represent Chapter 23: Residues and waste from the food industries; prepared animal fodder. The 3rd-4th digits "06" represent heading 2306: Oil-cake and other solid residues resulting from the extraction of vegetable fats or oils. The 5th-6th digits "20" represent the subheading: Linseed meal. Under 2306, subheadings are subdivided by oilseed type: 230610 cottonseed meal, 230620 linseed meal, 230630 sunflower seed meal, 230641-230649 rapeseed meal (by low erucic acid/other), 230650 coconut or copra meal, 230660 palm nuts or palm kernels meal, 230690 other. Therefore 230620 specifically refers to the cake and meal after oil extraction from linseed. Linseed meal is the solid residue after linseed has been pressed or solvent-extracted for oil, meeting the 2306 definition of "oilseed cake and meal after oil extraction." It is not classified in Chapter 12 (oleaginous seeds) because oil has been extracted; not in 2309 (prepared feed) because no other ingredients have been mixed; not in 2304 (soybean meal) because the raw material is different. Therefore it is classified under 230620.

Product name: The specific name of the declared commodity, which should use standard Chinese or English, such as "linseed meal" or "Flaxseed meal." Raw material: State the type of oilseed from which the meal is produced, specifying "linseed" and whether it has undergone pressing or solvent extraction. Processing method: Describe the oil extraction process, such as "cake and meal obtained after pressing" or "meal obtained after solvent extraction," and whether high-temperature treatment was applied. Whether made into pellets: Declare whether the meal has been made into pellets; pelletization does not affect classification but must be truthfully declared. Protein content: Declare the crude protein content range of the product, which helps confirm quality and use but is not required for classification. Use: State the main use, such as "raw material for animal feed," and it must not be declared for human consumption. Brand type: Declare whether there is a brand; if no brand, fill in "no brand"; if branded, fill in the name. Packaging specifications: Declare the packaging method and net weight per package, such as "bulk" or "50 kg/bag." Product name: Linseed meal; Raw material: Linseed; Processing method: Cake and meal obtained after pressing for oil extraction, not solvent-extracted; Whether made into pellets: No; Protein content: Crude protein ≥32%; Use: Raw material for animal feed; Brand type: No brand; Packaging specifications: Bulk. Mistakenly declaring linseed meal as "linseed flour," which should be classified in Chapter 12 if not oil-extracted. Failing to state the processing method, which may raise suspicion of being a non-oil-extracted linseed product. Declaring pelleted linseed meal as "compound feed," leading to classification under 2309.

Core classification basis: 1) The goods must be solid residues after oil extraction, i.e., the oil has already been extracted; 2) The raw material must be linseed; 3) Not prepared or mixed with other substances, maintaining the nature of a single feed raw material; 4) Complying with Chapter 23 notes and the text of heading 2306. If linseed has not been oil-extracted or only partially oil-extracted, it is classified under Chapter 12 as oleaginous seeds; if prepared into retail-packaged feed, it is classified under 2309. 120799 Other oil seeds and oleaginous fruits: Raw linseed or non-oil-extracted linseed flour is classified under this code, while 230620 is the meal after oil extraction; the key difference is whether oil has been extracted. 230400 Soybean meal: Different raw material; 230400 specifically refers to cake and meal after soybean oil extraction, while 230620 is linseed meal; the two cannot be substituted for each other. 230690 Other oilseed meal: 230690 is other oilseed meal not elsewhere specified under 2306; linseed meal already has a specific subheading 230620, so it is not classified under 230690. 230990 Other prepared animal feed: 230990 is mixed or prepared feed, which may contain linseed meal ingredients, but 230620 is single linseed meal without other substances added. Is the raw material linseed? Has the oil already been extracted? Is it a single ingredient without other substances mixed in? Is it not made into retail-packaged feed? Does it not belong to Chapter 12 oleaginous seeds?

What is the difference in HS codes between linseed meal and linseed flour? Linseed meal is the residue after oil extraction from linseed and is classified under 230620; linseed flour is linseed directly ground without oil extraction and is classified under Chapter 12 (such as 120799). The key difference is whether oil has been extracted, and proof of processing technology is required for customs declaration. How can I check the import tariff rate for 230620? Tariff rates change. It is recommended to use the official website of the General Administration of Customs, the International Trade Single Window, or professional tariff query tools, entering HS code 230620 along with the country of origin, trade mode, and other conditions to obtain real-time rates. Note the difference between MFN rates, agreement rates, and general rates. Is a test report required when declaring linseed meal? A quality test report is usually required, such as protein content, moisture, impurities, etc., to prove compliance with feed standards. Some countries also require a phytosanitary certificate. The specific requirements are subject to the importing country's customs. Can linseed meal be classified under 230690? No. 230690 is "other oilseed meal," while linseed meal already has a specific subheading 230620. According to the General Rules for HS classification, specific descriptions take precedence over general descriptions, so it should be classified under 230620. If a small amount of other oilseed meal is mixed into linseed meal, how should it be classified? If after mixing it is still predominantly linseed meal and the essential character has not changed, it is usually still classified under 230620; if the mixing proportion is large, it may be regarded as prepared feed and classified under 2309. It is recommended to truthfully declare the mixed ingredients and proportions and let customs determine. What should be noted when selling linseed meal through cross-border e-commerce? Cross-border e-commerce is usually for personal use, but linseed meal is a raw material for animal feed and may be subject to import and export controls. It is necessary to confirm whether personal mailing is allowed and comply with animal and plant quarantine regulations. It is recommended to import through general trade. How should the "processing method" declaration element for linseed meal be filled in? The oil extraction process should be filled in detail, such as "cake and meal obtained after pressing oil extraction" or "meal obtained after solvent extraction," and state whether high-temperature treatment was applied. This helps customs confirm that it belongs to 2306 rather than other chapters. Are 230620 and 230400 easily confused during customs declaration? Yes, especially when the product name is only written as "oilseed meal." The raw materials are different: 230400 specifically refers to soybean meal, and 230620 specifically refers to linseed meal. The raw material type must be clearly stated during customs declaration to avoid rejection or penalties due to classification errors.
