Chapter 32 covers chemical products such as tanning materials, dyes, pigments, paints, varnishes, putty, and inks. The core of this chapter is preparations used for coloring, coating, decorating, or protecting, but it excludes specific chemicals already classified in other chapters (such as compounds with separate chemical definitions). This chapter includes vegetable tanning extracts, synthetic organic dyes, color lakes, pigments, paints, varnishes, putty, printing inks, etc., which are widely used in textiles, construction, printing, plastics, and other industries. Heading 3214 covers non-refractory surface-coating preparations, including glass putty, jointing compounds, resin cements, caulking compounds, putty, surface-coating preparations (such as non-refractory coatings for walls, floors, and metal surfaces), and similar-purpose preparations. However, it excludes refractory surface-coating preparations (classified under 3816), ordinary paints and varnishes (classified under 3208-3210), and articles that have been formed or hardened (such as plastic sheets, gypsum boards, etc.). The first 2 digits "32" represent Chapter 32: tanning materials, dyes, pigments, paints, putty, and inks. The 3rd-4th digits "14" represent heading 3214: non-refractory surface-coating preparations, glass putty, jointing compounds, resin cements, caulking compounds, putty. The 5th-6th digits "90" represent subheading 3214.90: other non-refractory surface-coating preparations, i.e., other similar preparations not listed in 3214.10 (glass putty, jointing compounds, resin cements, caulking compounds, putty). Therefore, 321490 specifically refers to non-refractory surface-coating preparations other than putty-type products, such as caulking, sealing, and coating materials used in construction and industry. This product is classified under 321490 rather than adjacent codes because it is a non-refractory surface-coating preparation and does not belong to the specifically named goods in 3214.10 such as glass putty or jointing compounds. At the same time, it does not meet the definition of paints and varnishes under 3208-3210 (usually based on synthetic polymers, forming a film by solvent evaporation), nor does it have refractory characteristics (otherwise it would be classified under 3816). Therefore, 321490 is a residual subheading applicable to other non-refractory surface-coating preparations not otherwise specified.

Product name: The standard name of the declared product, which should accurately reflect its chemical composition and use, such as "non-refractory wall surface-coating preparation." Composition: List the main components and their content, such as resins, solvents, fillers, pigments, etc., and indicate whether refractory substances are contained. Use: Explain the specific application scenario, such as building wall caulking, metal surface coating, floor sealing, etc. Appearance: Describe the physical state, such as paste, liquid, powder, mastic, etc., which helps determine whether it belongs to surface-coating preparations. Packaging specifications: Indicate the packaging form and net weight, such as drum, tube, bag, etc., which affects tax rates and regulatory conditions. Brand: Declare the brand or model; if there is no brand, indicate "no brand" for customs intellectual property verification. Whether refractory: Clearly state whether it has refractory performance; refractory materials should be classified under 3816, and non-refractory under 3214. Customs declaration example: Product name: Non-refractory wall surface-coating preparation Composition: Acrylic resin 30%, calcium carbonate 40%, water 20%, additives 10% Use: Used for caulking and surface coating of building interior walls Appearance: White paste Packaging specifications: 20 kg/drum Brand: No brand Whether refractory: No HS code: 321490 Declaration elements: Product name, composition, use, appearance, packaging specifications, brand, whether refractory Misreporting a non-refractory surface-coating preparation as a refractory material (3816), resulting in incorrect classification. Misclassifying putty-type products (3214.10) under 321490, ignoring the subheading distinction. Incomplete declaration of composition, such as failure to indicate the resin type, affecting classification determination.

Core classification criteria: First confirm whether the product is a non-refractory surface-coating preparation, i.e., used for surface coating, caulking, sealing, etc., but without refractory performance. Second, exclude the specifically named glass putty, jointing compounds, resin cements, caulking compounds, and putty under 3214.10. Finally, confirm that it does not belong to the paints and varnishes of 3208-3210 (usually based on synthetic polymers, forming a film by solvent evaporation) or the refractory materials of 3816. If the product meets the above conditions, it is classified under 321490. 321410 Glass putty, jointing compounds, resin cements, caulking compounds, putty: 321410 specifically names putty-type products, while 321490 is other non-refractory surface-coating preparations. If the product is putty or jointing compound, it should be classified under 321410 rather than 321490. 320890 Other paints and varnishes: 320890 refers to paints and varnishes based on synthetic polymers, usually forming a film by solvent evaporation, while 321490 refers to surface-coating preparations, which may not contain film-forming substances or have a different film-forming method. 381600 Refractory cements, refractory mortars, refractory concretes, etc.: 381600 refers to refractory materials, while 321490 is explicitly non-refractory. If the product has refractoriness, it should be classified under 3816. 350610 Prepared glues and other prepared adhesives, not elsewhere specified or included: 350610 refers to adhesives, mainly used for bonding, while 321490 refers to surface-coating preparations, mainly used for coating, caulking, and sealing, with different functions. Is the product clearly non-refractory? Does it belong to the specifically named goods under 3214.10 such as putty or jointing compounds? Is it based on synthetic polymers and does it form a film by solvent evaporation? Is it used for surface coating, caulking, or sealing? Have chapters such as 3208-3210 and 3816 been excluded?

How can I check the import tax rate for 321490? You can check the latest import tariff, value-added tax, and consumption tax rates by entering HS code 321490 on the General Administration of Customs website, China International Trade Single Window, or third-party query platforms. Note that tax rates may vary depending on trade agreements and country of origin. What is the difference between 321490 and 321410? 321410 specifically names glass putty, jointing compounds, resin cements, caulking compounds, and putty; 321490 refers to other non-refractory surface-coating preparations, such as wall coating agents and sealing pastes. If the product is putty-type, it should be classified under 321410. What declaration elements are required for non-refractory surface-coating preparations? Usually, product name, composition, use, appearance, packaging specifications, brand, and whether refractory must be declared. The composition must list the main substances and content, the use must be specific, and whether refractory must be clear. Does 321490 require commodity inspection for export? Export commodity inspection requirements depend on the specific composition of the goods and the destination country. Some chemical products may involve dangerous goods or statutory inspection. It is recommended to check the Catalogue of Import and Export Commodities Subject to Inspection and Quarantine by Entry-Exit Inspection and Quarantine Authorities or consult the local customs. If a surface-coating preparation has refractoriness, which code should it be classified under? If it has refractoriness, it should be classified under 3816 (refractory cements, refractory mortars, refractory concretes, etc.), not 321490. Refractoriness usually means the ability to withstand high temperatures without losing performance. Can 321490 be used for cross-border e-commerce retail? Yes, but note that cross-border e-commerce retail imported goods must comply with the positive list and may involve consumption tax. For export, the regulations of the destination country must be followed. It is advisable to understand the list and tax rates in advance. How can paints and surface-coating preparations be distinguished during classification? Paints are usually based on synthetic polymers and form a film after solvent evaporation, classified under 3208-3210; surface-coating preparations may not contain film-forming substances or have a different film-forming method, and are mainly used for caulking, sealing, and coating, classified under 3214. What are the regulatory conditions for 321490? Regulatory conditions vary by country. In China, import may involve an inbound goods customs clearance form, dangerous goods business qualification, etc. For details, you can check the Regulatory Conditions Code Table issued by the General Administration of Customs or consult a customs broker.
