Chapter 73 covers articles of iron or steel, including plates, rods, profiles, tubes, wires and articles thereof, but excludes ferrous waste and scrap, iron or steel powders, ferro-alloys and other products classified in other chapters. This chapter ranges from basic iron and steel materials to various finished iron and steel products, such as structural components, containers, chains, springs, tools, etc., and is an important chapter for the classification of iron and steel commodities in international trade. Heading 7315 specifically covers iron or steel chain and parts thereof, including articulated link chain, welded link chain, roller chain, other chain and parts of chain. Chains under this heading are mainly used for transmission, conveying, lifting, binding and other purposes, and the material must be iron or steel, whether or not surface-treated or fitted with attachments. Code 731519 is a six-digit subheading: the first 2 digits '73' represent Chapter 73 (articles of iron or steel); digits 3-4 '15' represent heading 7315 (iron or steel chain and parts thereof); digits 5-6 '19' represent the subheading 'other chain', i.e. iron or steel chain under 7315 other than specifically named chains such as articulated link chain, welded link chain and roller chain. This subheading covers various types of iron or steel chain not specifically named, such as round link chain, flat link chain, special-purpose chain, etc. The goods are iron or steel chain, not specifically named as articulated link chain, welded link chain or roller chain, and are therefore classified under 731519 (other chain). If it were articulated link chain it should be classified under 731511, welded link chain under 731512, and roller chain under 731511 or 731512 (depending on the specific type), while 731519 serves as a residual subheading covering other iron or steel chain not elsewhere specified.

🎯 Classification Logic
The core criteria for classification are: 1. The material must be iron or steel; 2. It must be chain and parts thereof; 3. It is not specifically named as articulated link chain, welded link chain or roller chain. If it were articulated link chain it should be classified under 731511, welded link chain under 731512, and roller chain under 731511 (depending on the specific type), while 731519 is a residual subheading. 731511 Articulated link chain: Articulated link chain is formed by hinged plates, pins, etc., and is often used for transmission; 731519 is other chain, such as round link chain, flat link chain, etc., with a different structure. 731512 Welded link chain: Welded link chain is formed by welding links and is often used for lifting; 731519 is other chain not elsewhere specified, such as non-welded round link chain. 731520 Roller chain: Roller chain has rollers and is used for transmission; 731519 is other chain without a roller structure. 731581 Other chain parts: 731581 covers chain parts, such as links, plates, etc.; 731519 covers complete chain, not parts. 731589 Other chain parts: 731589 covers other chain parts; 731519 covers complete chain, and the difference lies in whether it is complete. Confirm the material is iron or steel, excluding chains of other metals or non-metals. Confirm whether it is articulated link chain, welded link chain or roller chain; if so, classify under the corresponding subheading. Confirm whether it is a complete chain rather than a chain part. Confirm whether the use affects classification, such as transmission, lifting, etc. Confirm whether it is fitted with attachments; attachments must be classified separately.
