Zinc alloy Hs Code

Zinc alloy harmonized system code

Product Overview Zinc alloy classified under HS Code 790120 refers to alloys predominantly composed of zinc, typically combined with elements such as aluminum, copper, and magnesium to enhance mechanical properties. These alloys exhibit high corrosion resistance, excellent castability, and favorable tensile strength, with typical zinc content exceeding 85%. They are supplied as ingots, slabs, or billets in various purity grades and processing levels, including die-cast and wrought forms. The HS Code 790120 further subdivides into specific alloy compositions and forms used in secondary manufacturing. Commercially, zinc alloys serve critical roles in food service equipment, retail fixtures, and processing machinery due to their antimicrobial properties, dimensional stability, and ease of fabrication. Their application extends to ornamental hardware, automotive components, and electrical fittings, offering a cost-effective alternative to pure zinc or other base metals. The product’s market positioning emphasizes durability, recyclability, and compliance with environmental regulations, providing importers and manufacturers a reliable material solution aligned with global sustainability standards. HS Code Classification & Trade Specifications The full HS Code 790120 falls under Chapter 79 (Zinc and articles thereof), Heading 7901 (Unwrought zinc), with subheading 790120 specifically denoting zinc alloys in unwrought form. This classification is grounded in the product’s chemical composition and physical state, differentiating it from pure zinc and other metal alloys. Trade documentation requires precise identification of alloy type and processing condition to ensure compliance with customs protocols. Common packaging includes standardized steel drums, wooden crates, or palletized bundles, designed to prevent moisture ingress and mechanical damage during transit. Preservation techniques often involve surface passivation or protective coatings to mitigate oxidation. Quality standards conform to internationally recognized specifications such as ASTM B86 and ISO 1179, guaranteeing chemical purity, mechanical properties, and dimensional tolerances. Adherence to WTO trade regulations and the Harmonized System nomenclature ensures seamless customs clearance and facilitates accurate tariff application, critical for import/export businesses, customs brokers, and trade compliance officers managing global zinc alloy transactions.
