Chapter 83 covers miscellaneous articles of base metal, including locks, hinges, decorative fittings, frames, pipe fittings, wire mesh, chains, etc. These articles are typically made of base metals such as iron, steel, copper, or aluminum, but are not classified under more specific chapters (such as Chapter 73 for iron and steel articles, or Chapter 74 for copper articles). This chapter is characterized by goods that are mostly general-purpose metal articles and do not involve mechanical or electrical functions. Heading 8308 covers clasps, hooks, eyes, rivets, tubular rivets, split pins, cotter pins, washers, and similar articles of base metal, mainly used for clothing, footwear, luggage, tents, furniture, etc., serving to fasten, connect, or decorate. It includes ordinary rivets, tubular rivets, spring washers, etc. Code 830820 is a six-digit subheading: the first two digits 83 indicate Chapter 83 for miscellaneous articles of base metal; digits 3-4, 08, indicate heading 8308, i.e., clasps, hooks, eyes, rivets, tubular rivets, split pins, cotter pins, washers, and similar articles of base metal; digits 5-6, 20, indicate subheading 830820, specifically referring to rivets and tubular rivets. Note: 830820 only includes rivets and tubular rivets, and does not include other similar articles such as split pins (classified under 830890). This commodity is a rivet, which is a fastening and connecting piece of base metal, meeting the description of heading 8308. Rivets are typically used for permanent connections, differing from threaded fasteners (such as screws, classified under 7318), and also differing from pins (such as split pins, classified under 830890). Therefore, it is classified under 830820, rather than 7318 or 830890.

Product Name: The Chinese and foreign language names of the declared commodity should be specific and clear, such as "base metal rivets" or "tubular rivets." Material: The specific base metal material of the declared rivets, such as iron, steel, copper, aluminum, etc., and whether surface treatment (such as galvanizing) has been applied. Type: The type of declared rivets, such as ordinary rivets, tubular rivets, blind rivets, etc. Use: The main use of the declared rivets, such as for clothing, luggage, automobiles, construction, etc. Dimensions: The dimensions of the declared rivets, such as diameter and length, usually expressed in millimeters. Brand: The brand or manufacturer name of the declared rivets; if there is no brand, indicate "no brand." Model: The model or specification of the declared rivets, such as M4, M5, etc. Customs declaration example: Product Name: Base metal rivets Material: Steel, galvanized surface Type: Blind rivets Use: For automobile body connection Dimensions: Diameter 4mm, length 10mm Brand: XX Model: M4-10 Quantity: 10,000 pieces Remarks: None Material declaration is not specific, such as writing only "metal"; it should clearly state iron, steel, copper, etc. Type confusion, incorrectly declaring tubular rivets as ordinary rivets, affecting classification. Use description is vague, such as "for fixing"; it should be specific to the application field.

The core basis for classification is the "Import and Export Tariff" and the "HS Explanatory Notes." Rivets are permanent connecting pieces of base metal, usually fixed by deformation (such as hammering or pulling). Heading 8308 explicitly includes rivets and tubular rivets. If the rivets are threaded, they should be classified under 7318 (threaded articles); if they are split pins, they should be classified under 830890. Therefore, material, type, and whether they are threaded are the key determining factors. 731815 Screws: Screws are threaded fasteners and are removable; rivets are unthreaded and provide permanent connection. 830890 Other base metal articles: 830890 includes split pins, washers, etc., but does not include rivets; rivets are specifically classified under 830820. 761610 Aluminum rivets: If the rivets are made of aluminum and are for specific uses (such as construction), they may be classified under 7616, but general rivets are still classified under 830820. 741539 Copper rivets: If copper rivets are used for clothing, etc., they are classified under 830820; if for other industrial uses, they may be classified under 7415. Is the material a base metal? Is it a permanent connecting piece? Is it unthreaded? Does it belong to rivets or tubular rivets? Is it used in general fields such as clothing or luggage?

How do I check the tax rate for HS code 830820? You can check the latest import tax rate and export rebate rate by entering code 830820 on the official website of the General Administration of Customs, China International Trade Single Window, or third-party query platforms. Note that tax rates may change, and the official published rates shall prevail. How do I distinguish between rivets and screws during declaration? Rivets are unthreaded and provide permanent connection; screws are threaded and removable. During declaration, they should be accurately described based on physical characteristics to avoid classification errors. Are tubular rivets and ordinary rivets classified under the same code? Yes, both tubular rivets and ordinary rivets are classified under 830820, but the type should be indicated during declaration for customs review. Is there a difference in classification between stainless steel rivets and aluminum rivets? Generally, both are classified under 830820, but if aluminum rivets are specifically used in a particular industrial field, they may be classified under 7616. It is recommended to make a comprehensive judgment based on use and material. What are common errors in the declaration elements for rivets? Common errors include non-specific material declaration, type confusion, vague use, and missing dimensions. They should be filled in detail to ensure consistency with the actual goods. If rivets are used in aerospace, will the classification change? It may change. Rivets used in aerospace may be classified under 8803 or other chapters, depending on the specific material and use. It is recommended to consult professional classification personnel. How do I declare rivets for cross-border e-commerce small parcel export? Cross-border e-commerce small parcel exports also require truthful declaration, providing elements such as product name, material, type, and use. The declaration may be simplified, but the code must be accurate. What is the main difference between HS code 830820 and 830890? 830820 specifically refers to rivets and tubular rivets; 830890 includes other base metal articles such as clasps, hooks, eyes, split pins, washers, etc. The difference lies in the specific type of goods.
