Product Overview Galvanised pipes classified under HS Code 730630 are steel pipes that have undergone a hot-dip galvanisation process, wherein a protective zinc coating is applied to enhance corrosion resistance. These pipes are typically manufactured from carbon steel or mild steel, with standard diameters ranging from 10 mm to 200 mm and wall thicknesses conforming to international standards such as ASTM A53 or EN 10240. The galvanisation ensures durability against environmental factors, making the pipes suitable for applications requiring longevity and structural integrity. Within the HS Code 730630 category, products are subdivided into seamless and welded pipes, with surface finishes and zinc coating thicknesses often specified to meet industry benchmarks. Commercially, galvanised pipes under this classification are extensively utilized in food service infrastructure, retail shelving systems, and various processing industries where hygiene and resistance to rust are critical. Their robust construction combined with corrosion protection offers a competitive advantage in international markets, providing reliable performance for importers and exporters focused on durable piping solutions. HS Code Classification & Trade Specifications The HS Code 730630 is structured hierarchically as follows: Chapter 73 (Iron and Steel), Heading 7306 (Other tubes, pipes and hollow profiles, seamless, of iron or steel), and Subheading 730630 (Other tubes, pipes and hollow profiles, welded, of iron or steel, galvanised). This classification is applicable due to the welded manufacturing process and the subsequent galvanisation treatment, distinguishing these pipes from seamless or non-galvanised variants. For international trade compliance, galvanised pipes are typically packaged in bundles secured with steel straps and protected by anti-corrosive wrapping or coatings to prevent damage during transit. Preservation methods comply with ISO 14713 standards for zinc coatings, ensuring consistent quality upon delivery. Shipping specifications mandate adherence to customs documentation requirements including certificate of origin, material test reports, and conformity declarations aligned with WTO agreements. Quality standards such as ISO 9001 and EN 10240 are commonly referenced to verify manufacturing consistency and galvanisation integrity, supporting smooth customs clearance and facilitating trade across global markets.
