Questions
HS code 721631: common questions
What is HS code 721631?

The first two digits (72) are the chapter — Iron and steel — and digits 3-4 (7216) are the heading. Countries add further digits (8-10) for their national tariff line.
What products fall under HS 721631?
Common products classified under 721631 include U-channel, U-beam, steel channel, C-channel and similar items matching u sections. The correct code still depends on the product's material, function and intended use.
How do I find the import duty for HS code 721631?
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 721631 the same in every country?
The first 6 digits (721631) 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.
