Steel washer Hs Code

Steel washer harmonized system code

Product Overview Steel washers classified under HS Code 731822 are flat, circular components typically manufactured from carbon or alloy steel, designed to distribute load and prevent damage to surfaces in bolted assemblies. These washers exhibit precise dimensional tolerances, with thicknesses generally ranging from 0.5 mm to 10 mm and diameters varying according to application requirements. Processing methods include cold stamping, machining, and heat treatment to enhance mechanical strength and corrosion resistance. The classification 731822 encompasses washers not coated with other metals, differentiating them from plated or alloyed variants. These washers are integral in various commercial sectors, notably in food service equipment, retail shelving assemblies, and industrial processing machinery, where durability and compliance with hygiene standards are critical. Their robust mechanical properties, combined with standardized sizing, facilitate interchangeability and ease of assembly, positioning them as essential hardware components within global supply chains. HS Code Classification & Trade Specifications The HS Code 731822 falls under Chapter 73 (Articles of iron or steel), Heading 7318 (Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers, and similar articles), with the subheading 731822 specifically designating flat steel washers without plating or coating. This classification is based on material composition and manufacturing processes consistent with World Customs Organization (WCO) guidelines. Trade professionals should note that steel washers under this code are commonly packaged in bulk quantities using moisture-resistant materials such as polyethylene liners within corrugated fiberboard cartons to mitigate corrosion risks during transit. Preservation techniques include application of rust inhibitors or desiccants, adhering to international shipping standards to maintain product integrity. Quality standards typically reference ISO 8746 and ASTM F436 for dimensional accuracy and mechanical performance, ensuring compliance with import/export regulations and facilitating customs clearance. This precise classification and adherence to standardized trade practices support efficient customs processing and global distribution.

Steel washer 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.
