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 castings, forgings, screws, springs, etc.). This chapter does not include copper ores (Chapter 26), copper waste and scrap (Chapter 72) and certain mechanical and electrical products (Chapters 84/85). The core is the smelting, processing and classification of finished products around copper metal. Heading 7419 covers other articles of copper, including copper castings, forgings, stampings, articles of copper not elsewhere specified, etc. This heading is a residual heading used to classify copper finished products that are not specifically named in other headings (such as 7401-7418). Under 7419 are included copper castings, copper forgings, copper springs, copper chains, copper cloth, copper nails, etc. Note: if a copper casting is dedicated to a certain machine, it may be classified in Chapters 84/85, but castings for general purposes are classified in 7419. HS code 741991 is a 6-digit subheading. The first 2 digits "74" represent Chapter 74 (copper and articles thereof), covering all primary forms, semi-finished products and finished products of copper and copper alloys. Digits 3-4 "19" represent heading 7419 (other articles of copper), i.e., copper finished products not named in 7401-7418. Digits 5-6 "91" represent subheading 741991, specifically "copper castings", i.e., articles of copper or copper alloys formed by the casting process, not further worked or only simply worked. This subheading is not further subdivided; all copper castings (regardless of specific use, shape, alloy composition) are classified under this code. Copper castings are copper products formed by the casting process and belong to copper finished products. Since they are not specifically named in 7401-7418 (such as copper plates, copper wire, etc.), they are classified under 7419 "other articles of copper". Under 7419, subheading 741991 is explicitly "copper castings", so the goods should be classified under 741991, not other subheadings of 7419 (such as forgings, stampings, etc.). If the casting is dedicated to a certain machine, it may be classified as a machine part, but castings for general purposes are classified under this code.

Product name: The Chinese and English names of the declared goods shall be accurately described as "copper castings" or a specific name, such as "bronze castings", "brass castings", etc. Material: State the specific composition of the copper alloy, such as bronze (copper-tin alloy), brass (copper-zinc alloy), cupronickel (copper-nickel alloy), etc., as well as the content of main elements. Processing method: State "casting" and explain the casting process (such as sand casting, precision casting, etc.) to distinguish it from forgings, stampings, etc. Use: Explain the specific use of the casting, such as "for valves", "for pump bodies", "general mechanical parts", etc. The use affects whether it is classified as a machine part. Shape and dimensions: Describe the shape of the casting (such as cylindrical, irregular) and main dimensions (such as diameter, length) so that customs can confirm whether it is a finished product. Whether further worked: State whether the casting has been further worked (such as turning, milling, drilling, etc.). If only deburred or ground, it is still classified under this code. Brand or model: If there is a brand or model, it should be declared so that customs can identify it. If there is no brand, write "no brand". Product name: Bronze casting (for valves); Material: Bronze (copper 88%, tin 10%, zinc 2%); Processing method: Sand casting; Use: Used to manufacture valves; Shape and dimensions: Cylindrical, outer diameter 50mm, height 30mm; Whether further worked: Not further worked, only deburred; Brand: No brand. Misreporting copper castings as copper forgings or copper stampings, resulting in classification errors. Failure to provide alloy composition, so customs cannot determine whether it is a copper alloy casting. Unclear use description; if dedicated to a certain machine, it may be classified in Chapters 84/85. Ignoring whether further worked; if turned, etc., it may be regarded as a machine part.

Core basis for classification: first confirm the material is copper or copper alloy; second confirm the processing method is casting; third confirm whether it belongs to articles not named in other subheadings under 7419; finally confirm whether it is dedicated to a certain machine. If dedicated to a certain machine, classify as a machine part (such as 8481 valve parts); if it is a general casting, classify under 741991. At the same time, refer to the Explanatory Notes to the Import and Export Tariff of the People's Republic of China for 7419. 7419.99 Other articles of copper: 7419.99 is another subheading under 7419, including copper forgings, stampings, springs, etc., while 7419.91 specifically refers to copper castings. The difference lies in the processing method: castings are classified under 7419.91, others under 7419.99. 8481.90 Valve parts: If a copper casting is dedicated to a valve and has been further worked into a valve part, it should be classified under 8481.90; if it is only a casting blank and has not become a part, classify under 7419.91. 7325.99 Other cast articles of iron or steel: Different material: copper castings are classified under 7419.91, iron or steel castings under 7325.99. They must be distinguished by material testing. 7403.29 Other copper alloys: 7403 is unwrought copper alloys, while 7419.91 is articles formed by casting, which is beyond the scope of unwrought. 7418.20 Sanitary ware and parts thereof, of copper: If the copper casting is a part of sanitary ware, such as a faucet body, it may be classified under 7418.20; but castings for general industrial use are classified under 7419.91. Is the material copper or copper alloy? Is the processing method casting? Is it dedicated to a certain machine? Has it been further machined? Does it belong to articles already named in other subheadings of 7419?

What is the difference in HS codes between copper castings and copper forgings? Copper castings are classified under 741991, and copper forgings under 741999 (other articles of copper). The difference lies in the processing method: casting is pouring molten metal into a mold to form, while forging is forming metal by hammering or pressure. The processing method must be specified when declaring, otherwise it may lead to classification errors. If a copper casting is used for automobiles, which code should it be classified under? If the copper casting is a part dedicated to automobiles and has been further worked, it may be classified in Chapter 87 (vehicles and parts thereof). But if it is only a casting blank and has not become a specific part, it is still classified under 741991. The judgment should be based on whether it has the characteristics of a dedicated part. How to check the import tariff rate for 741991? It can be checked through the website of the General Administration of Customs of China or the Import and Export Tariff of the People's Republic of China. The rate varies by country and trade agreement (such as RCEP). It is recommended to use customs classification query tools or consult a customs broker. Note that rates may be adjusted annually, subject to the latest announcement. What documents are required by customs when declaring copper castings? Usually, contracts, invoices, packing lists, bills of lading, customs declarations, and material certificates (such as composition test reports) are required. If anti-dumping is involved, certificates of origin, etc. may also be required. It is recommended to confirm with a customs broker in advance. Are bronze castings and brass castings the same in HS code? Yes, both are classified under 741991, because this subheading is divided by processing method (casting) rather than alloy type. However, the specific alloy composition must be stated when declaring for customs statistics and valuation. If a copper casting has been turned, is it still classified under 741991? If turning is only to remove burrs or for simple finishing, it is still classified under 741991. But if turning makes it a specific machine part (such as a valve part), it may be classified in Chapters 84/85. The judgment should be based on the degree of processing and use. How to distinguish 741991 and 741999 when declaring? 741991 specifically refers to copper castings, and 741999 refers to other articles of copper (such as forgings, stampings, springs, etc.). The processing method must be specified when declaring. If it is casting, classify under 741991; otherwise, classify under 741999. How to determine the HS code for copper castings sold via cross-border e-commerce? First confirm the material is copper, the processing method is casting, and the use is general. If so, classify under 741991. It is recommended to use customs HS code query tools or consult a professional customs broker. Note that simplified declaration may apply to cross-border e-commerce retail exports, but the code still needs to be accurate.
