HS Code 251010

HS code 251010 is the World Customs Organization 6-digit HS 2022 subheading for "Natural calcium phosphates, natural aluminium calcium phosphates and phosphatic chalk : Unground". The first two digits (25) are the chapter — Salt; sulphur; earths and stone; plastering materials, lime and cement — and digits 3-4 (2510) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 251010 include unground phosphate rock, raw phosphate, phosphate ore and similar items matching unground. The correct code still depends on the product's material, function and intended use.

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.

The first 6 digits (251010) 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.

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.
