HS Code 290943

HS code 290943 is the World Customs Organization 6-digit HS 2022 subheading for "Ethers, etheralcohols, etherphenols, etheralcoholphenols, alcohol peroxides, ether peroxides, ketone peroxides (whether or not chemically defined), and their halogenated, sulphonated, nitrated or nitrosated derivatives : Etheralcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives : Monobutyl ethers of ethylene glycol or of diethylene glycol". The first two digits (29) are the chapter — Organic chemicals — and digits 3-4 (2909) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 290943 include butyl cellosolve, ethylene glycol monobutyl ether, butyl glycol, 2-butoxyethanol and similar items matching monobutyl ethers of ethylene glycol or of…. 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 (290943) 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.
