Chapter 74 covers copper and articles thereof, including copper mattes, unrefined copper, refined copper, copper alloys, copper materials (such as bars, rods, profiles, wire, plates, sheets, strip, foil) and copper finished products (such as copper tubes, copper sanitary ware, copper tableware, etc.). However, this chapter does not include copper machine parts, electrical components, etc., which are usually classified under Chapter 84 or 85. Copper washers, as general-purpose copper parts, if used in machines or vehicles, may need to be judged based on their use whether to be classified under other chapters. Heading 7415 covers copper nails, tacks, drawing pins, staples (used for shoemaking, furniture, etc.) and similar articles, as well as copper screws, bolts, nuts, washers and similar articles. These goods are usually used for fastening, connecting or sealing, and are general-purpose parts. However, if a washer is specially designed for a certain type of machine or equipment, even if made of copper, it may be classified under the corresponding machine part heading. Code 741521 is a six-digit subheading. The first two digits 74 represent Chapter 74 (copper and articles thereof). Digits 3-4, 15, represent heading 7415 (copper nails, screws, nuts, washers and other fasteners). Digits 5-6, 21, represent subheading 741521, specifically copper washers (including spring washers). This subheading is usually not further subdivided, but depending on the type of copper alloy (such as brass, bronze) or use, additional information such as composition and dimensions may need to be provided. Note: If the washer has other materials (such as rubber), it may affect classification. Copper washers are classified under 741521 because their material is copper and they belong to the washer category of fasteners, conforming to the description of heading 7415. They are not classified under other subheadings of 7415 (such as screws, nuts), nor under Chapter 73 iron and steel articles, nor under Chapter 84 machine parts, unless the washer is specially designed for a certain machine and constitutes an essential part thereof. However, according to the General Rules for the Interpretation of the Harmonized System, if the washer is a general-purpose part, it should still be classified under 741521.

🎯 Classification Logic
The core criteria for classification are: 1) The material must be copper or copper alloy; 2) The product must be a washer, i.e., an annular part used to prevent leakage, loosening or disperse pressure; 3) Whether it is a dedicated part. If the washer is specially designed for a certain machine and constitutes an essential part thereof, it may be classified under Chapter 84 or 85; but if it is a general-purpose washer, it is classified under 741521. In addition, attention should be paid to the distinction from plastic washers (3926), rubber washers (4016) and iron and steel washers (7318). 73182200 Iron and steel washers: Different material, 73182200 is made of iron and steel, while 741521 is made of copper. Classification is first distinguished by material. 39269090 Plastic washers: Material is plastic, classified under Chapter 39. If a copper washer has a plastic coating, it should be judged based on its essential character. 40169310 Vulcanized rubber washers: Material is rubber, classified under Chapter 40. If a copper washer is combined with rubber, it should be classified according to the main material. 84841000 Combined washers (metal + rubber): Made of a combination of metal and rubber, classified under Chapter 84. Not applicable to pure copper washers. Is the material copper or copper alloy? Does it belong to the washer category of fasteners? Is it specially designed for a certain machine? Is it combined with other materials? Are the specifications and dimensions fully declared?
