What is HS code 740500?

HS code 740500 is the World Customs Organization 6-digit HS 2022 subheading for "Master alloys of copper". The first two digits (74) are the chapter — Copper and articles thereof — and digits 3-4 (7405) are the heading. Countries add further digits (8-10) for their national tariff line.

How do I find the import duty for HS code 740500?

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 740500 the same in every country?

The first 6 digits (740500) 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.

Is HSN code 740500 the same as HS code 740500?

Yes at the 6-digit level. India's HSN (Harmonized System of Nomenclature) uses the same WCO base, so HSN 740500 covers the same "master alloys of copper" scope; India then extends it to 8 digits for GST and customs. Check the Indian Customs tariff (CBIC) for the full national line.
