Questions
HS code 250840: common questions
What is HS code 250840?
HS code 250840 is the World Customs Organization 6-digit HS 2022 subheading for "Other clays (not including expanded clays of heading 6806), andalusite, kyanite and sillimanite, whether or not calcined; mullite; chamotte or dinas earths : Other clays". The first two digits (25) are the chapter — Salt; sulphur; earths and stone; plastering materials, lime and cement — and digits 3-4 (2508) are the heading. Countries add further digits (8-10) for their national tariff line.
What products fall under HS 250840?
Common products classified under 250840 include clay, kaolin, ball clay, fire clay, stoneware clay, earthenware clay and similar items matching other clays. The correct code still depends on the product's material, function and intended use.
How do I find the import duty for HS code 250840?
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 250840 the same in every country?
The first 6 digits (250840) 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.
