Chapter 74 covers copper and articles thereof, including copper ingots, copper materials, copper wire, copper plates, copper foil, copper tubes, copper fittings, and various copper finished products. Copper materials in this chapter are usually processed through smelting, casting, rolling, extrusion, etc., but do not exceed the scope specified in the notes to this chapter. Copper alloys (such as brass, bronze, cupronickel) are also classified in this chapter. It should be noted that this chapter does not include copper mechanical parts, electrical components, and other goods already classified in other chapters. Heading 7415 covers copper fasteners, including nails, tacks, drawing pins, staples, bolts, nuts, screws, washers, rivets, etc. These goods are used to connect or fasten other objects and are made of copper or copper alloys. However, heading 7415 does not include copper springs (classified in 7320), copper chains (classified in 7419), or copper electrical terminals (classified in 8536). Code 741539 consists of 6 digits. The first 2 digits "74" represent Chapter 74 (copper and articles thereof), indicating the material is copper or copper alloy. Digits 3-4 "15" represent heading 7415 (copper fasteners), indicating the function is connection or fastening. Digits 5-6 "39" represent subheading 741539, namely "other copper fasteners," which is a residual subheading used to cover copper fasteners not specifically named under other subheadings of 7415 (such as 741510, 741521, 741529, 741533, etc.). Therefore, 741539 specifically refers to copper fasteners other than those specifically named such as nails, bolts, nuts, etc., such as copper washers, rivets, cotter pins, etc. This product is a copper fastener, but it is not a type specifically named in heading 7415 (such as nails, bolts, nuts, etc.), so it is classified under residual subheading 741539. If it were a copper spring, it should be classified in 7320; if it were a copper chain, it should be classified in 7419; if it were a copper electrical terminal, it should be classified in 8536. Correct classification must be determined based on the product's material, function, and whether it is named in other subheadings of 7415.

🎯 Classification Logic
The core criteria for classification are: whether the product material is copper or copper alloy, whether the function is that of a fastener, and whether it is specifically named in other subheadings of heading 7415. If it is a copper fastener but not specifically named, it is classified under 741539. Attention must be paid to distinguishing it from copper springs, chains, electrical components, etc. 741510 Copper nails, tacks, drawing pins, staples: This subheading specifically names nail-type fasteners, while 741539 covers other unnamed fasteners. 741521 Copper washers (including spring washers): If it is a spring washer, it should be classified under 741521; but 741539 includes other types of washers, such as flat washers. 741529 Other copper screws, bolts, nuts: This subheading covers screws, bolts, and nuts, while 741539 covers fasteners other than these. 741533 Copper rivets: Rivets are already specifically named and should be classified under 741533, not 741539. 7320 Copper springs: Although springs are made of copper, their function is as elastic elements and they are not classified as fasteners; they should be classified under 7320. Is the material copper or a copper alloy? Is the function connection or fastening? Is it already named in other subheadings of 7415? Does it belong to springs, chains, or electrical components? Are the declaration elements complete and accurate?

This subheading specifically names nail-type fasteners, while 741539 covers other unnamed fasteners.
741521 - Copper washers (including spring washers)
If it is a spring washer, it should be classified under 741521; but 741539 includes other types of washers, such as flat washers.
741529 - Other copper screws, bolts, nuts
This subheading covers screws, bolts, and nuts, while 741539 covers fasteners other than these.
741533 - Copper rivets
Rivets are already specifically named and should be classified under 741533, not 741539.
7320 - Copper springs
Although springs are made of copper, their function is as elastic elements and they are not classified as fasteners; they should be classified under 7320.

❓ FAQ
What goods are specifically included in copper fasteners under HS code 741539? Mainly copper fasteners not named in other subheadings of 7415, such as copper flat washers, cotter pins, retaining rings, pin shafts, etc. However, note that spring washers should be classified under 741521, and rivets under 741533. How do you determine whether a copper fastener should be classified under 741539 or another subheading? First confirm whether the product is a copper fastener, then check whether it is specifically named under 7415. If it is specifically named (such as nails, bolts, nuts, rivets, etc.), classify it under the corresponding subheading; if not, classify it under 741539. Should copper washers be classified under 741521 or 741539? If they are spring washers, they should be classified under 741521; if they are other types of washers (such as flat washers, sealing washers), they should be classified under 741539. The type of washer must be clearly stated at declaration. Why can't copper rivets be classified under 741539? Because under heading 7415 there is already subheading 741533 specifically naming copper rivets. According to HS classification rules, specific naming takes precedence over residual subheadings, so rivets should be classified under 741533. What key information is required when declaring 741539? Product name, material (copper alloy type), use, brand, specifications and model, processing technique, surface treatment, etc. are required. Material and specifications and model are especially important, as they directly affect classification and customs valuation. How are copper fasteners and copper springs distinguished in classification? The function of a copper spring is to produce elastic deformation, and it is an elastic element, so it should be classified under heading 7320; copper fasteners are used for connection or fastening and are classified under 7415. If a product has both functions, it should be classified according to its primary function. If a copper fastener is used in electrical equipment, does that affect classification? If the fastener is a terminal specially designed for electrical equipment, it may be classified under 8536; but if it is only a general-purpose fastener, even if used in electrical equipment, it is still classified under 7415. Judgment should be based on the characteristics of the product itself. How can I check the tariff rate when importing copper fasteners? It can be checked through the official website of the General Administration of Customs, China International Trade Single Window, or professional classification databases. Enter HS code 741539, and note that the tariff rate may vary depending on trade agreements, place of origin, and other factors.
