Chapter 21 is the "Miscellaneous edible preparations" chapter in the Harmonized Commodity Description and Coding System, covering a wide range of products, mainly including extracts, essences and concentrates of coffee, tea and maté, and preparations with a basis of these products; yeast, baking powder; sauces and preparations therefor; soups and broths and preparations therefor; ice cream and other edible ice; and food preparations not elsewhere specified. The core characteristic of this chapter is that these goods are mostly processed foods or food ingredients, rather than primary agricultural products or single-component chemical substances. Heading 2102 covers "Yeast (active or inactive); other dead single-cell micro-organisms (excluding vaccines of heading 3002); prepared baking powders." This heading includes various products used for fermentation, leavening, or as microbial preparations. Among them, baking powder is a chemical leavening agent, usually made by mixing sodium bicarbonate, acid salts (such as sodium acid pyrophosphate) and fillers (such as corn starch), used in baking to produce carbon dioxide to make dough rise. Code 210230 is a six-digit subheading. The first 2 digits "21" represent Chapter 21 "Miscellaneous edible preparations", indicating that the product belongs to the category of processed foods. Digits 3-4 "02" represent heading 2102, namely "Yeast; other dead single-cell micro-organisms; prepared baking powders", which groups baking powder together with yeast and other leavening agents. Digits 5-6 "30" represent subheading 210230, specifically referring to "prepared baking powders". In the HS classification, subheadings are usually further subdivided according to product type or use, and 210230 clearly points to chemical baking powder, distinguishing it from active yeast (210210) and inactive yeast (210220). Baking powder is classified under 210230 rather than other food or chemical categories because of its specific use as a leavening agent for baking. It differs from chemically pure sodium bicarbonate of Chapter 28 (283630), because baking powder is a mixture and is dedicated to food fermentation; it also differs from bakery products of Chapter 19 (such as 1905), because baking powder is an ingredient rather than a finished product. Heading 2102 explicitly lists "prepared baking powders", so the product must be classified under this code.

Product name: The specific name of the declared product; a standardized Chinese or English product name should be used, such as "发酵粉" or "Baking powder". Ingredients: List the main ingredients and their contents, such as sodium bicarbonate, sodium acid pyrophosphate, corn starch, etc., and indicate the percentage of each ingredient. Use: Explain the use of the product, such as a leavening agent for baked goods, or for home baking, etc. Packaging specifications: Indicate the packaging form and net weight, such as bagged or canned, and the net weight in grams per package. Brand: Declare the brand of the product (if any); if there is no brand, state "no brand". Model or item number: If there is a product model or item number, it must be declared so that customs can identify it. Production date/shelf life: Declare the production date and shelf life to ensure compliance with food safety requirements. Product name: Baking powder; Ingredients: sodium bicarbonate 40%, sodium acid pyrophosphate 30%, corn starch 30%; Use: chemical leavening agent for baking cakes and bread; Packaging specifications: bagged, net weight 100 grams per bag; Brand: ABC; Model: BP-100; Production date: January 1, 2025; Shelf life: 24 months. Confusing baking powder with yeast and incorrectly classifying it under 210210 or 210220. Incomplete ingredient declaration, failing to list acid salts and fillers. Filling in the use as "food additive" without specifying the leavening function.

The core basis for classification is the function and ingredients of the product. Baking powder is a chemical leavening agent made by mixing alkaline substances (such as sodium bicarbonate), acidic substances and fillers, used in baking to produce carbon dioxide. According to the Explanatory Notes to the Import and Export Tariff, heading 2102 explicitly includes prepared baking powders, so as long as the product meets the definition of baking powder, it should be classified under 210230. If the product is single-component sodium bicarbonate, even if used in food, it should be classified under Chapter 28; if it is yeast, it should be classified under 210210 or 210220. 210210 Active yeast: Active yeast is a living microorganism that produces carbon dioxide through fermentation, while baking powder is a chemical mixture that does not require biological fermentation. 210220 Inactive yeast: Inactive yeast is killed yeast and may still have fermentation ability, but baking powder is purely a chemical leavening agent. 283630 Sodium bicarbonate: Sodium bicarbonate is a single compound, while baking powder is a mixture and is classified in the food chapter. 190120 Baking mix: Baking mix usually contains flour, sugar, etc., while baking powder serves only as a leavening agent, with different ingredients. Is the product a chemical leavening agent mixture? Does it contain sodium bicarbonate and acid salts? Is its use for baking leavening? Is it not a single component? Has it not been classified under Chapter 28 or Chapter 19?

Are baking powder and 泡打粉 the same thing? Is the HS code the same? Yes, baking powder and 泡打粉 usually refer to the same product, namely baking powder, and the HS code is 210230 in both cases. However, note that in some regions "泡打粉" may specifically refer to aluminum-containing formulas, while "发酵粉" may refer to aluminum-free formulas, but the classification remains unchanged. How can I check the import tariff rate for baking powder? The import tariff rate must be determined according to the country of origin, trade agreements, etc. You can check the MFN rate, agreement rate, etc. by entering HS code 210230 and the country of origin on the official website of the General Administration of Customs of China, the International Trade Single Window, or professional tariff query platforms. Rates may change, so it is recommended to rely on the latest published version. What declaration elements are required for exporting baking powder? Export declaration elements include product name, ingredients, use, packaging specifications, brand, model, etc. The specific requirements are subject to customs requirements. It is recommended to refer to the declaration elements for 210230 in the "Catalogue of Specifications for Declaration of Import and Export Commodities of the Customs of the People's Republic of China". Can baking powder be classified as a food additive? What is the HS code? Baking powder belongs to leavening agents among food additives, but the HS code is still 210230 because heading 2102 explicitly lists it. Food additives are dispersed across various chapters in the HS and must be classified according to specific ingredients and use. If baking powder contains aluminum, will the HS code change? No. Whether or not it contains aluminum, as long as it meets the definition of baking powder, it is classified under 210230. However, aluminum-containing baking powder may be subject to food safety regulation restrictions, and the ingredients must be truthfully provided when declaring. What is the difference between the HS codes for baking powder and yeast? Baking powder is 210230, active yeast is 210210, and inactive yeast is 210220. The main difference is that baking powder is a chemical leavening agent, while yeast is a microbial preparation. For cross-border e-commerce retail import of baking powder, how should the HS code be declared? Cross-border e-commerce retail imports also need to be declared according to the HS code, and baking powder should be classified under 210230. Product information, ingredients, use, etc. must be provided, and it must comply with the requirements of the cross-border e-commerce retail import commodity list. Is the HS code for baking powder consistent across countries? The first six digits of the HS code are unified internationally, and 210230 is consistent in most countries. However, countries may subdivide subsequent digits, such as the U.S. HTS 2102.30.0000 and the EU 2102.30.00, which are basically consistent.
