HS Code 292090

HS code 292090 is the World Customs Organization 6-digit HS 2022 subheading for "Esters of other inorganic acids of nonmetals (excluding esters of hydrogen halides) and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives : Other". The first two digits (29) are the chapter — Organic chemicals — and digits 3-4 (2920) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 292090 include inorganic esters, nonmetal acid esters, esters of inorganic acids, sulfonate esters and similar items matching esters of other inorganic acids of nonmetals. 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 (292090) 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.
