HS 730890 · Iron / steel structures and parts
Get the code right at quotation time, not at customs.
Misclassifying HS 730890 on the commercial invoice walks the cargo into the wrong duty rate, the wrong rebate column, and a customs hold that costs days of demurrage to clear. This page gives you the WCO heading, the product it most often covers, the China VAT export rebate rate, the US Section 301 status, the supplier provinces that ship it, and practitioner buying notes for first-time importers.
For an explanation of how the WCO Harmonized System is structured, what each digit means, and why misclassification is the most common landed-cost error first-time buyers make, see the HS code glossary entry.

Buying notes
Catchall for fabricated steel structures: warehouse columns and beams, bridge components, transmission towers, pre-engineered building modules, and welded structural assemblies. Chinese fabrication is highly competitive; Hebei and Shandong tonnages dominate. Section 301 25% on US import; Section 232 steel tariff (25%) stacks on top of Section 301, so the all-in tariff for fabricated steel from China to US is 50%. Other markets (AU, EU, Middle East, Africa) have not stacked tariffs at the same level.
