Chapter 83 covers miscellaneous articles of base metal, including locks, keys, hinges, door and window fittings, ornaments, picture frames, pipe fittings, etc. Although these articles are made of base metal, they are not classified entirely by material, but are listed separately according to their specific use and function. The difference between this chapter and Chapter 73 (articles of iron or steel), Chapter 74 (articles of copper), etc., is that goods of Chapter 83 usually have an independent function or decorative character and are not classified in other more specific chapters. Heading 8301 covers base metal locks (key locks, combination locks, padlocks, etc.), keys (including base metal keys not elsewhere specified), lock catches, and lock frames. Keys, as matching products for locks, are classified in this heading whether or not presented separately. However, note that locks for motor vehicles, furniture locks, etc., if specifically provided for elsewhere, are not classified in 8301. Code 830170 is a six-digit subheading: the first two digits 83 represent Chapter 83, miscellaneous articles of base metal; digits 3-4, 01, represent heading 8301, namely base metal locks and keys; digits 5-6, 70, represent subheading 830170, specifically referring to keys. This subheading covers keys made of various base metals, including ordinary keys, key blanks, decorated keys, etc., but does not include electric keys, electronic keys, and other keys with electronic functions (usually classified in other chapters). As a matching product for locks, a key functions to open locks and is an article of base metal. According to the General Rules for the interpretation of the HS, keys should be classified in heading 8301 because that heading explicitly names "keys." They are not classified in Chapter 73 (articles of iron or steel) because Chapter 83 has a more specific listing; they are not classified in Chapter 85 (electrical equipment) because ordinary keys have no electrical function; and they are not classified in Chapter 94 (furniture) because keys are not furniture parts.

Product name: The Chinese and foreign-language name of the declared commodity, which should accurately describe the type of key, such as "base metal key," "copper key," etc. Material: The main material of the declared key, such as iron, copper, zinc alloy, stainless steel, etc., which must be specified. Use: Explain the use of the key, such as for padlocks, door locks, furniture locks, etc., which helps with classification. Brand: Declare the brand or model of the key; if there is no brand, indicate "no brand." Specifications and dimensions: Declare the size, length, thickness, etc., of the key to facilitate customs inspection. Whether with lock: Declare whether the key is presented together with a lock; if presented separately, it is classified in 830170. Processing method: Declare the processing method of the key, such as casting, stamping, cutting, etc. Example of customs declaration: Product name: Base metal key Material: Copper alloy Use: For padlock Brand: ABC Specifications: Length 50 mm, width 20 mm Whether with lock: Presented separately Processing method: Stamping HS code: 8301700000 Declaration elements: 1. Product name: Base metal key; 2. Material: Copper alloy; 3. Use: Padlock; 4. Brand: ABC; 5. Specifications: 50*20 mm; 6. Whether with lock: No; 7. Processing method: Stamping. Incorrectly classifying keys presented with locks under other subheadings of 8301; they should actually be classified separately. The material is not declared specifically, for example only writing "metal," which may lead to classification disputes. Ignoring brand declaration; customs may require supplementary declaration.

Core basis for classification: the key must be made of base metal and have the function of opening locks. According to the HS Explanatory Notes, 830170 specifically refers to base metal keys, including keys not elsewhere specified. If a key has electronic components (such as a chip), it may be classified in Chapter 85. If a key is a toy or ornament, it may be classified in Chapter 95 or Chapter 71. Classification requires a comprehensive judgment based on material, function, and use. 830110 Padlocks: 830110 is padlocks, while 830170 is keys. If a key and a padlock are presented together, they should be classified separately; if the key is presented separately, it is classified in 830170. 830140 Other locks: 830140 covers other locks, such as door locks, furniture locks, etc. As an accessory, if a key is presented together with a lock, it is usually classified with the lock; if presented separately, it is classified in 830170. 820559 Other hand tools: 820559 includes certain tools similar to keys, but keys are specially used for locks, and 830170 has a specific listing, so they should be classified in 830170 first. 732690 Other articles of iron or steel: 732690 is a residual code for articles of iron or steel, but keys have a specific listing in 830170, so they are not classified in 732690. 854370 Other electrical equipment: 854370 covers electronic keys, magnetic card keys, etc. If a key has an electronic function, it should be classified in 854370 rather than 830170. Is the key made of base metal? Is the key presented separately? Does the key have an electronic function? Is the key specially used for locks? Has the key already been classified under another more specific code?

Which HS code should be checked for keys? Keys should be classified under HS code 830170. When checking, first determine Chapter 83, miscellaneous articles of base metal, then find heading 8301, locks and keys, and finally subheading 830170, which is keys. Note: if the key has an electronic function, check Chapter 85. When a key and lock are presented together, how should the HS code be filled in? If a key and lock are presented together, it is usually declared under the HS code of the lock, such as padlocks under 830110. But if the key is presented separately, it is classified in 830170. It is recommended to declare them separately to avoid classification errors. Are the HS codes for copper keys and iron keys the same? Yes, as long as the key is made of base metal, it is classified in 830170. However, when declaring, the specific material, such as copper or iron, must be indicated for customs statistics and inspection. What is the HS code for electronic keys? Electronic keys (such as those with chips or magnetic cards) are usually classified in Chapter 85, such as 854370. If it is only an ordinary metal key, it is classified in 830170. The key criterion is whether it has an electronic function. Is the HS code for key blanks also 830170? Yes, key blanks (unfinished keys), if made of base metal, are also classified in 830170. But if the key blank has already been processed into a specific shape, it is still classified under this code. Is the HS code for car keys 830170? If a car key is a traditional mechanical key, it is classified in 830170; if it is an electronic remote-control key, it is classified in Chapter 85. Judgment should be based on function. What are the declaration elements for keys? The main declaration elements include: product name, material, use, brand, specifications and dimensions, whether with lock, processing method, etc. Detailed completion helps with rapid customs clearance. With which codes are keys easily confused during classification? They are easily confused with 830110 (padlocks), 830140 (other locks), 820559 (hand tools), 732690 (other articles of iron or steel), etc. The key difference is that keys are lock accessories, and 830170 has a specific listing.
