HS Code 310560

HS code 310560 is the World Customs Organization 6-digit HS 2022 subheading for "Mineral or chemical fertilisers containing two or three of the fertilising elements nitrogen, phosphorus and potassium; other fertilisers; goods of this chapter in tablets or similar forms or in packages of a gross weight not exceeding 10 kg : Mineral or chemical fertilisers containing the two fertilising elements phosphorus and potassium". The first two digits (31) are the chapter — Fertilisers — and digits 3-4 (3105) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 310560 include PK fertilizer, phosphorus-potassium fertilizer, phosphate potash, potassium phosphate and similar items matching mineral or chemical fertilisers containing the…. 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 (310560) 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.
