Leaf spring Hs Code

Leaf spring harmonized system code

Product Overview Leaf springs classified under HS Code 732010 refer to flat or slightly curved metallic components primarily manufactured from high-grade steel alloys, designed to absorb shocks and provide flexible support in mechanical assemblies. These springs typically exhibit precise dimensions ranging from 200 mm to 1200 mm in length, with thicknesses between 5 mm and 20 mm, depending on application requirements. The production process involves heat treatment, quenching, and tempering to achieve optimal tensile strength and fatigue resistance, ensuring durability under cyclic loading conditions. HS Code 732010 encompasses various subcategories including flat springs, curved leaf springs, and laminated assemblies, each differentiated by shape and mechanical properties. Commercially, these components find extensive application in sectors such as automotive suspension systems, industrial machinery, and agricultural equipment, facilitating load distribution and vibration damping. Their robust construction and compliance with international metallurgical standards position them as essential components in global supply chains, offering reliable performance and adaptability across diverse industrial environments. HS Code Classification & Trade Specifications The HS Code 732010 falls under Chapter 73 (“Articles of Iron or Steel”), specifically Heading 7320 (“Springs and Leaves for Springs of Iron or Steel”), with Subheading 732010 designating leaf springs. This classification is justified by the product’s material composition, mechanical function, and manufacturing process, aligning with WTO Harmonized System conventions for steel spring components. Trade professionals commonly package leaf springs in reinforced wooden crates or metal containers, employing corrosion inhibitors and desiccants to preserve surface integrity during maritime or air freight transport. Standard shipping units vary but often include bundles secured with steel strapping to maintain shape and prevent deformation. Quality control adheres to ISO 9001 and ASTM A229 standards, ensuring consistent mechanical properties such as minimum yield strength of 1100 MPa and elongation of 8-12%, critical for compliance with import regulations and customs documentation. These specifications facilitate accurate tariff classification, risk assessment, and inventory management within international trade frameworks.

Leaf spring 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.
