Chapter 74 covers copper and articles thereof, including copper ingots, copper materials, copper products, etc. The copper in this chapter includes refined copper, copper alloys, cupronickel, etc., but certain copper products such as copper springs, copper tableware, etc. may be classified under other chapters. The tariff structure of this chapter is mainly divided according to the form of copper and the degree of processing, from raw materials to semi-finished products and then to finished products. Heading 7415 covers copper fasteners, such as screws, bolts, nuts, washers, etc., as well as similar copper articles for industrial use. These goods are usually used in machinery, electronics, construction and other fields for connection and fixation. Note that this heading does not include copper springs (classified under 7320) or copper chains (classified under 7419), etc. Code 741533 is a 6-digit subheading. The first 2 digits 74 represent Chapter 74, copper and articles thereof. The 3rd-4th digits 15 represent heading 7415, namely copper fasteners. The 5th-6th digits 33 represent subheading 741533, specifically copper screws. In the HS classification, the 5th digit usually indicates the subheading level, and the 6th digit further subdivides it. For 7415, subheadings are divided by specific commodity type, such as 741510 for copper nails, 741520 for copper washers, etc., and 741533 specifically refers to copper screws. Copper screws are classified under 741533 because they are screws made of copper and used for fastening, which conforms to the description of heading 7415. They are different from copper nails (741510) or copper washers (741520), and also different from steel or iron screws (7318). When classifying, it is necessary to confirm that the material is copper and that the item is a screw type, rather than other fasteners.

📝 Declaration Elements
Product name: The specific name of the declared commodity, such as "copper screw", which should accurately reflect the attributes of the commodity. Material: Explain the type of copper, such as brass, copper, bronze, etc., as well as the grade or composition. Specification and model: Includes diameter, length, thread specification, etc., such as M3x10mm. Use: Explain the usage scenario of the screw, such as electronic equipment, furniture, machinery, etc. Brand: If there is a brand, the brand name must be declared; if there is no brand, fill in "none". Processing technology: Such as turning, thread rolling, casting, etc., which affects classification. Product name: copper screw; Material: brass H62; Specification and model: M4x12mm; Use: used for fixing electronic connectors; Brand: none; Processing technology: turning. The material declaration is unclear, such as writing only "copper" without distinguishing brass or copper, which may lead to classification disputes. The specification and model are incomplete, lacking thread dimensions, which affects the customs' accurate identification of the commodity. The use description is too broad, such as "for industry", without being specific, which may raise doubts.
Product name
The specific name of the declared commodity, such as "copper screw", which should accurately reflect the attributes of the commodity.
⚠️ Writing only "screw" without indicating the material, or mistakenly writing it as "iron screw".
Material
Explain the type of copper, such as brass, copper, bronze, etc., as well as the grade or composition.
⚠️ Writing only "copper" without further detail, or confusing the type of copper alloy.
Specification and model
Includes diameter, length, thread specification, etc., such as M3x10mm.
⚠️ Incomplete specifications, writing only "small screw".
Use
Explain the usage scenario of the screw, such as electronic equipment, furniture, machinery, etc.
⚠️ The use is too general, such as "for fixing".
Brand
If there is a brand, the brand name must be declared; if there is no brand, fill in "none".
⚠️ Failure to declare the brand or mistakenly declaring it as another brand.
Processing technology
Such as turning, thread rolling, casting, etc., which affects classification.
⚠️ Failure to declare the process, or inaccurate process description.
Example： Product name: copper screw; Material: brass H62; Specification and model: M4x12mm; Use: used for fixing electronic connectors; Brand: none; Processing technology: turning.
Common Mistakes：
The material declaration is unclear, such as writing only "copper" without distinguishing brass or copper, which may lead to classification disputes.
The specification and model are incomplete, lacking thread dimensions, which affects the customs' accurate identification of the commodity.
The use description is too broad, such as "for industry", without being specific, which may raise doubts.
🎯 Classification Logic
The core criteria for classification are: whether the commodity is made of copper, whether it is a screw type, and whether it belongs to fasteners. According to the HS notes, heading 7415 includes copper screws, bolts, nuts, etc., but attention must be paid to the difference from steel or iron fasteners (7318). Material is the primary factor, and copper alloy products are also classified under this chapter. In addition, the difference between screws and nails lies in whether there is a thread. Screws usually have threads, while nails do not. 731815 Steel or iron screws: The material is steel or iron, not copper; when classifying, it should be judged according to the material. Copper products are classified under 7415, and steel or iron products under 7318. 741510 Copper nails: Copper nails usually have no threads and are used for hammering in, while screws have threads and are used for turning in. 741520 Copper washers: Washers are flat rings used to distribute pressure, while screws are threaded fasteners. 741539 Other copper fasteners: This subheading covers copper fasteners not elsewhere specified, such as copper bolts, nuts, etc., while 741533 specifically refers to screws. Is the material copper or a copper alloy? Does the commodity have threads? Is it used for fastening? Is it a screw rather than a nail or washer? Are the specifications and model complete?
