Questions
HS code 730512: common questions
What is HS code 730512?
HS code 730512 is the World Customs Organization 6-digit HS 2022 subheading for "Other tubes and pipes (for example, welded, riveted or similarly closed), having circular crosssections, the external diameter of which exceeds 406,4 mm, of iron or steel : Line pipe of a kind used for oil or gas pipelines : Other, longitudinally welded". The first two digits (73) are the chapter — Articles of iron or steel — and digits 3-4 (7305) are the heading. Countries add further digits (8-10) for their national tariff line.
What products fall under HS 730512?
Common products classified under 730512 include longitudinal welded pipe, L-welded pipe, DSAW pipe, long seam pipe and similar items matching other. The correct code still depends on the product's material, function and intended use.
How do I find the import duty for HS code 730512?
Duty is set by the destination country, not by the 6-digit HS code alone. Start from the official tariff of your market — USITC HTS (US), TARIC / Access2Markets (EU), GOV.UK Trade Tariff (UK), CBSA (Canada), ABF (Australia) or Singapore Customs — and look up the full national code with China as the country of origin.
Is HS code 730512 the same in every country?
The first 6 digits (730512) are the same worldwide under the WCO Harmonized System. Beyond that, each country extends the code (HTS in the US, TARIC in the EU, etc.) and sets its own duty and tax rates.
Can I trust the HS code a 1688 supplier gives me?
Treat a supplier-provided code as a clue, not a final classification. It can be incomplete, China-export-specific, or mismatched to your destination's rules. Verify against the official tariff and your product's actual material and use.
