Import Tips & Compliance
ā¢ Provide Certificate of Analysis confirming purity >99% to verify as chemically defined compound under Chapter 29 note (a)
ā¢ Ensure proper HAZMAT documentation (UN1155) and UN-approved containers for volatile flammable liquid import
ā¢ Avoid packaging suggesting retail sale to prevent reclassification under Chapter 38 mixtures

Anhydrous Diethyl Ether
Water-free diethyl ether used in Grignard reactions and moisture-sensitive syntheses. Falls under 2909.11.00.00 as pure acyclic ether; anhydrous state is standard purification, not rendering it specific-use per Chapter 29 note (e).
Diethyl Ether ACS Reagent Grade
American Chemical Society specification diethyl ether for analytical procedures. Chemically defined acyclic ether under 2909.11.00.00; ACS specs ensure reagent purity without specific-use additives.
Stabilized Diethyl Ether
Diethyl ether with added BHT stabilizer to prevent peroxide formation during storage/transport. Permitted under Chapter 29 note (f) as stabilizer necessary for preservation; remains classified as 2909.11.00.00.
Diethyl Ether Pharmaceutical Intermediate
High-purity diethyl ether used in synthesis of pharmaceutical APIs. Qualifies under 2909.11.00.00 as chemically defined acyclic ether; not excluded as finished immunological product per Chapter 29 note (e).
Technical Grade Diethyl Ether
Industrial diethyl ether (95-98% purity) for paint stripping and reaction solvent. Still classified 2909.11.00.00 as it meets 'whether or not containing impurities' per Chapter 29 note (a).
Diethyl Ether Extraction Solvent
Diethyl ether specifically for natural product extractions (essential oils, alkaloids). General solvent use keeps classification at 2909.11.00.00; not specific enough for exclusion.
