HS Code 290911

HS code 290911 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 : Acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives : Diethyl ether". 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 290911 include diethyl ether, ethyl ether, ether, anesthetic ether and similar items matching diethyl ether. 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 (290911) 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.
