Motorcycle chain Hs Code

Motorcycle chain harmonized system code

Product Overview Motorcycle chains classified under HS Code 731511 refer to precision-engineered metal chains specifically designed for power transmission in motorcycles. These chains consist of interconnected metal links, typically manufactured from high-strength alloy steel, processed through heat treatment to enhance wear resistance, tensile strength, and fatigue durability. The product range within this classification includes roller chains, silent chains, and O-ring or X-ring sealed chains, each tailored to specific torque and speed requirements. Key physical specifications often include pitch sizes ranging from 420 to 630 series, tensile strengths exceeding 10,000 N, and corrosion-resistant surface treatments such as zinc plating or nickel coating. Commercially, these chains are integral components in motorcycle drivetrains, enabling efficient power transfer from the engine to the rear wheel, thereby ensuring optimal performance and safety. Their robust design and adherence to international manufacturing standards position them competitively within the global aftermarket and OEM supply chains, meeting stringent quality demands of manufacturers, distributors, and repair service providers. HS Code Classification & Trade Specifications The complete HS Code for motorcycle chains is 731511, where Chapter 73 covers “Articles of Iron or Steel,” Heading 7315 denotes “Chain and parts thereof,” and Subheading 731511 specifies “Chains of iron or steel, whether or not plated or coated, of a kind used for motorcycles.” This classification is assigned due to the product’s material composition and its functional application in motorcycle power transmission systems. From a trade perspective, these chains are commonly packaged in sealed, corrosion-inhibiting plastic bags or metal tins, then placed in reinforced cartons to prevent mechanical damage during international shipping. Preservation methods focus on anti-corrosive coatings and desiccants to maintain product integrity. Compliance with ISO 606 and JIS standards is often required for quality assurance, ensuring dimensional accuracy, tensile strength, and fatigue resistance. Documentation for customs clearance must reflect precise product descriptions and harmonized codes consistent with WTO guidelines to facilitate smooth cross-border transactions. Proper classification under HS Code 731511 supports tariff determination, trade statistics compilation, and regulatory adherence for importers, exporters, and trade compliance professionals.

Motorcycle chain Chapter Note

1.- In this Chapter the expression “cast iron” applies to products obtained by casting in which iron predominates by weight over each of the other elements and which do not comply with the chemical composition of steel as defined in Note 1 (d) to Chapter 72. 2.- In this Chapter the word “wire” means hot or cold-formed products of any cross-sectional shape, of which no cross-sectional dimension exceeds 16 mm.
