Chapter 12 covers oil seeds and oleaginous fruits, miscellaneous grains, seeds and fruit, industrial or medicinal plants, straw, fodder. The goods in this chapter are mostly primary plant-derived products, including oil crops such as soybeans and peanuts, as well as flavoring or industrial seeds such as mustard seeds and poppy seeds. Classification within the chapter is based on botanical properties, use and processing state, emphasizing that non-roasted, non-further-processed seeds and kernels are preferentially classified in this chapter, while deeply processed products are usually classified in subsequent chapters. Heading 1207 covers other oil seeds and oleaginous fruits, including mustard seeds, poppy seeds, sesame seeds, sunflower seeds, safflower seeds, cotton seeds, castor seeds, etc., whether or not broken. However, note that this heading does not include seeds for sowing (classified in 1209) or roasted, seasoned or food-prepared kernels (classified in Chapter 20). Mustard seeds here refer to mustard seeds that are whole, broken or ground but not further seasoned, mainly used for oil extraction or making condiments. The first 2 digits "12" represent Chapter 12, i.e. oil seeds and oleaginous fruits, miscellaneous grains, seeds and fruit, industrial or medicinal plants, straw, fodder. The 3rd-4th digits "07" represent heading 1207, i.e. other oil seeds and oleaginous fruits, specifically including mustard seeds, poppy seeds, sesame seeds, etc. The 5th-6th digits "50" are subheading 120750, specifically referring to mustard seeds, whether or not broken. Therefore, the complete code 120750 precisely locates the commodity mustard seeds, distinguishing it from sesame seeds (120740), poppy seeds (120791), etc. under the same heading. Mustard seeds are oil seeds and have not been roasted or further seasoned, conforming to the description of heading 1207. They differ from seeds for sowing of 1209 because 120750 specifically refers to mustard seeds used for oil pressing or seasoning; they also differ from condiments of 2103 because 2103 covers mustard products already made into mustard sauce or mixed seasonings. Therefore, mustard seeds in primary form should be classified under 120750.

Product name: The specific name of the declared commodity should be stated as mustard seeds, and varieties such as black mustard seeds, brown mustard seeds, yellow mustard seeds, etc. may be added. Whether broken: State the physical state of the mustard seeds, such as whole, broken or ground, but if ground and not seasoned, they are still classified under this heading. Use: Declare its final use, such as for oil pressing, making condiments, planting, etc., but seeds for sowing should be classified under 1209. Processing method: Describe the processing method, such as not roasted, not seasoned, only simply treated by cleaning, drying, etc. Ingredient content: Declare the main ingredients, such as mustard seed content, moisture, impurities, etc., to confirm that no other substances are mixed in. Packaging specifications: State the packaging form, such as bulk, bagged, net weight per bag, etc., affecting inspection, quarantine and statistics. Brand or origin: Provide the brand (if any) or country of origin, used for rules of origin and trade statistics. Customs declaration example: Product name: Mustard seeds (yellow mustard seeds) HS code: 120750 Declaration elements: 1. Product name: mustard seeds; 2. Whether broken: whole; 3. Use: for making condiments; 4. Processing method: not roasted, not seasoned; 5. Ingredient content: mustard seeds 99%, moisture 1%; 6. Packaging specifications: 25 kg/bag; 7. Brand: none; 8. Origin: Canada. The above declaration is clear and complete, facilitating customs classification and valuation. Incorrectly classifying mustard seeds for sowing under 120750, when they should actually be classified under 1209. Classifying roasted or seasoned mustard seeds under 120750, when they should actually be classified under Chapter 20 or 2103. Ignoring the "whether broken" element, leading to confusion with mustard powder and affecting classification.

The core basis for classification is the natural properties, processing state and use of the goods. As oil seeds, if mustard seeds are not roasted, not seasoned and not for sowing, they should be classified under 120750. If they are seeds for sowing, they are classified under 1209; if they have been roasted or seasoned, they are classified under Chapter 20 or 2103. At the same time, reference should be made to the Explanatory Notes to the Import and Export Tariff on 1207 to ensure compliance with the definition of "other oil seeds and oleaginous fruits". 120740 Sesame seeds: Sesame seeds and mustard seeds both belong to heading 1207, but different subheadings. Sesame seeds are classified under 120740, mustard seeds under 120750, distinguished by botanical species. 120799 Other oil seeds and oleaginous fruits: 120799 is the residual subheading under heading 1207. Mustard seeds already have a specific subheading 120750, so they are not classified under 120799. 1209 Seeds, fruit and spores for sowing: 1209 covers seeds for sowing. If mustard seeds are used for planting, they should be classified under 1209 rather than 120750. 2103 Condiments and mixed seasonings: 2103 covers mustard paste, mustard powder, etc. already made into condiments. If mustard seeds are only simply processed and not seasoned, they are still classified under 120750. 2008 Fruit, nuts and other edible parts of plants, prepared or preserved by other methods: If mustard seeds are roasted or further processed, they may be classified under 2008 rather than 120750. Is it for sowing? Has it been roasted or seasoned? Is it broken or ground but not seasoned? Is it mixed with other seeds? Are the use and processing method clearly declared?

The HS code for mustard seeds is 120750, but why do customs brokers sometimes suggest 120799? 120799 is the residual subheading under heading 1207, applicable to other oil seeds not otherwise specified. However, mustard seeds already have a specific subheading 120750 and should be preferentially classified under 120750. Misuse of 120799 may lead to classification errors and customs questions. If mustard seeds are for sowing, which code should they be classified under? Mustard seeds for sowing should be classified under 1209, and the specific subheading depends on whether they are seeds for planting. 120750 applies only to mustard seeds not for sowing, such as those used for oil pressing or seasoning. After mustard seeds are ground into powder, are they still classified under 120750? If no other seasonings are added after grinding, it is still simple processing and may be classified under 120750. But if after grinding they are mixed with other spices or made into condiments, they should be classified under 2103. Which code should roasted mustard seeds be classified under? Roasted mustard seeds have exceeded the processing scope of 1207 and are usually classified under Chapter 20, such as 2008 (other edible parts of plants prepared or preserved by other methods). The specific classification depends on the processing method and use. How to distinguish the HS codes for mustard seeds and mustard paste? Mustard seeds are primary agricultural products, classified under 120750; mustard paste is a seasoned product, classified under 2103. The key difference is whether they have been seasoned and made into paste form. What declaration elements are required when declaring mustard seeds? Product name, whether broken, use, processing method, ingredient content, packaging specifications, brand or origin, etc. are required. Ensure the declaration elements are complete and accurate for customs classification. How to check the import tariff rate for mustard seeds? Tariff rates may change. It is recommended to check the latest rates through the official website of the General Administration of Customs or the Import and Export Tariff. At the same time, pay attention to preferential rates under free trade agreements, which require a certificate of origin. If mustard seeds are mixed with a small amount of other seeds, does it affect classification? If other seeds are mixed in and the basic characteristics are not changed, they are usually still classified as mustard seeds. But if the mixing proportion is high, they may be regarded as a mixture and need to be reclassified according to the main ingredients and use.
