Chapter 83 covers miscellaneous articles of base metal, including locks, hinges, door and window fittings, decorative pieces, frames, pipe clamps, fasteners, bells, picture frames, sanitary ware, etc. Although these articles are made of base metal, they are neither in the general classification of iron and steel articles of Chapter 73 nor in the tools or cutlery of Chapter 82. Goods of this chapter are mostly everyday hardware items, widely used in furniture, construction, luggage, clothing, and other fields, and are common light industrial products in international trade. Heading 8308 covers base metal fasteners, buckles, hooks, rings, eyes, tubular rivets, beads, sequins, etc., commonly used in clothing, luggage, footwear, safety belts, pet supplies, etc. It includes snap fasteners, spring buckles, clasps, D-rings, slider buckles, side-release buckles, hook-and-eye closures, etc. Note, however, that this heading does not include fasteners dedicated to a specific type of goods (such as slide fasteners of Chapter 96), nor does it include locks (8301) or hinges (8302). The first 2 digits 83: indicates Chapter 83, miscellaneous articles of base metal. Digits 3-4, 08: indicates heading 8308, i.e., base metal fasteners, buckles, hooks, rings, eyes, etc. Digits 5-6, 90: indicates subheading 8308.90, i.e., other fasteners, covering base metal fasteners not elsewhere specified. Note that under 8308 there are also 8308.10 (snap fasteners and parts thereof), 8308.20 (tubular or bifurcated rivets), and 8308.90 (other). Therefore, 830890 specifically refers to other base metal fasteners other than snap fasteners and tubular rivets, such as spring buckles, clasps, D-rings, side-release buckles, etc. The goods are base metal fasteners and are not more specifically classified under 8308.10 (snap fasteners) or 8308.20 (tubular rivets), so they are classified under 8308.90. If they were plastic fasteners, they should be classified under Chapter 39; if they were slide fasteners, under 9607; if they were locks, under 8301; if they were fasteners dedicated to clothing, they would still be classified under 8308.

Product name: The specific name of the declared goods, such as "metal spring buckle", "metal side-release buckle", etc., must be consistent with the actual goods. Material: Specify the type of base metal, such as iron, steel, copper, zinc alloy, aluminum alloy, etc., and surface treatment may be noted. Use: Explain the application field of the fastener, such as for luggage, clothing, safety belts, pet leashes, etc. Brand: If there is a brand, declare the brand name; if there is no brand, fill in "none". Model: Declare the model or specification of the product to facilitate customs identification. Dimensions: Provide the main dimensions of the fastener, such as length, width, diameter, etc. Processing method: Briefly describe the manufacturing process, such as stamping, casting, electroplating, etc. Product name: metal spring buckle; Material: zinc alloy; Use: for connecting luggage shoulder straps; Brand: none; Model: SP-2024; Dimensions: length 5 cm, width 2 cm; Processing method: die-cast and then electroplated. Mistakenly classifying plastic fasteners under 830890, when they should actually be classified under Chapter 39. Mistakenly classifying snap fasteners under 830890, when they should actually be classified under 830810. Mistakenly classifying tubular rivets under 830890, when they should actually be classified under 830820. Failing to distinguish fasteners from locks; locks should be classified under 8301. Mistakenly classifying slide fasteners under 830890; slide fasteners should be classified under 9607.

Core criteria for classification: 1. The material is base metal; 2. It belongs to fasteners, buckles, hooks, rings, etc.; 3. It is not a fastener dedicated to a specific type of goods (such as slide fasteners); 4. It is not more specifically classified under other subheadings of 8308. If made of plastic, classify under Chapter 39; if it is a slide fastener, classify under 9607; if it is a lock, classify under 8301. 830810 Snap fasteners and parts thereof: Snap fasteners are a specific type of fastener, usually composed of two parts, fastened by pressing. 830890 covers other types of fasteners, such as spring buckles, side-release buckles, etc. 830820 Tubular or bifurcated rivets: Rivets are used for permanent connection, while fasteners of 830890 can usually be opened and closed repeatedly. 830230 Other locks for motor vehicles: Locks have an anti-theft function, while fasteners are mainly used for connection or fixation. 960720 Parts of slide fasteners: Slide fasteners are continuous interlocking devices, and their parts are classified under 9607, while 830890 is for individual fasteners. 392690 Other articles of plastics: Plastic fasteners are classified under 392690, and base metal fasteners under 830890. Is the material base metal? Does it belong to fasteners, buckles, hooks, rings, etc.? Can it be opened and closed repeatedly? Is it dedicated to a specific type of goods (such as slide fasteners)? Has it already been classified under other subheadings of 8308?

How can I check the import tariff rate for 830890? You can check through the official website of the General Administration of Customs of China or the International Trade Single Window. Enter HS code 830890, select the importing country, country of origin, and other information to obtain the MFN rate, general rate, VAT rate, etc. Note that tariff rates are adjusted with policy changes, so it is recommended to rely on the latest published information. What is the difference between 830890 and 830810? 830810 specifically refers to snap fasteners and parts thereof, i.e., press-fit fasteners; 830890 covers other base metal fasteners, such as spring buckles, side-release buckles, D-rings, etc. If the goods are snap fasteners, they should be classified under 830810; otherwise, under 830890. Can plastic fasteners be classified under 830890? No. 830890 applies only to base metal fasteners. Plastic fasteners should be classified under Chapter 39 according to their material, such as 392690. If the fastener is a combination of plastic and metal, it must be determined according to the predominant material or the General Rules for the Interpretation of the Harmonized System. Which code are metal fasteners used on clothing classified under? If made of base metal and not snap fasteners or rivets, they are usually classified under 830890. However, note that if the fasteners are declared together with the clothing, they may be classified as clothing; if declared separately, they are classified as fasteners. What are the declaration elements for 830890? Mainly include product name, material, use, brand, model, dimensions, processing method, etc. The specific requirements are subject to customs requirements. It is recommended to consult the latest "Catalogue of Standard Declaration Elements for Import and Export Goods of the Customs of the People's Republic of China" before declaration. Does export of 830890 require commodity inspection? Generally, 830890 is not a commodity subject to statutory inspection and quarantine and does not require commodity inspection. However, if exported to a specific country or for a specific use, it may need to meet the other party's requirements. It is recommended to consult the local customs or freight forwarder. How to distinguish 830890 from 960720? 830890 is an individual base metal fastener, such as a spring buckle; 960720 is a part of a slide fastener, such as a slider or teeth. If the goods are a component of a slide fastener, they should be classified under 9607, not 8308. How can I avoid classification errors for 830890? First confirm that the material is base metal, then determine whether it belongs to fasteners, buckles, etc., and exclude snap fasteners, rivets, locks, slide fasteners, etc. You may refer to the "Explanatory Notes to the Harmonized Commodity Description and Coding System" or consult a professional customs broker.
