Questions

HS code 730300: common questions

What is HS code 730300?

HS code 730300 is the World Customs Organization 6-digit HS 2022 subheading for "Tubes, pipes and hollow profiles, of cast iron". The first two digits (73) are the chapter — Articles of iron or steel — and digits 3-4 (7303) are the heading. Countries add further digits (8-10) for their national tariff line.

What products fall under HS 730300?

Common products classified under 730300 include cast iron pipe, cast iron tube, cast iron hollow profile and similar items matching tubes. The correct code still depends on the product's material, function and intended use.

How do I find the import duty for HS code 730300?

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 730300 the same in every country?

The first 6 digits (730300) 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.
