Ethylene Oxide (Pure)
Ethylene oxide is a colorless, flammable gas with the chemical formula C2H4O, classified as a three-membered ring epoxide under HTS 2910.10.00.00. It serves as a fundamental organic compound used primarily in industrial synthesis rather than for specific consumer applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as a ketone peroxide precursor
Certain epoxide-like compounds with peroxide functions may classify under other oxygen heterocyclic provisions if not strictly three-membered ring epoxides.
If diluted in solvents beyond transport allowances
Solutions exceeding Chapter 29 note (e) limits for solvents render it a mixture classifiable as chemical preparation rather than pure compound.

Import Tips & Compliance
• Classify as hazardous material under DOT regulations with proper UN 1040 labeling
• Provide Safety Data Sheets (SDS) and ensure cylinders meet DOT specifications
• Avoid misclassification as mixtures which may fall outside Chapter 29
Related Products under HTS 2910.10.00.00
Ethylene Oxide 99.9% Purity USP Grade
High-purity ethylene oxide meeting USP standards for pharmaceutical applications, a separate chemically defined epoxide under Chapter 29 note (a). It fits HTS 2910.10.00.00 due to its three-membered ring structure and lack of impurities affecting classification.
Stabilized Ethylene Oxide with Inhibitor
Ethylene oxide with added stabilizer for safe transport, permissible under Chapter 29 note (f) without changing its classification as the principal epoxide. It remains under HTS 2910.10.00.00 as the stabilizer is solely for preservation.
Ethylene Oxide in DOT-39 Cylinders
Compressed ethylene oxide gas packaged in non-refillable DOT-39 cylinders, a standard form for industrial shipment of this epoxide. Classified under HTS 2910.10.00.00 as the pure compound with transport packaging.
Industrial Ethylene Oxide for Sterilization
Ethylene oxide designated for gas sterilization in medical device manufacturing, still a separate chemically defined compound under HTS 2910.10.00.00. Its epoxide ring defines classification regardless of labeled end-use.
