HS Code for Ethylene oxide

Ethylene oxide is classified under HS code 2910.10 because it is a separate chemically defined organic compound belonging to the epoxide group. According to the General Rules of Interpretation (GRI) and the Chapter 29 notes, organic chemicals are classified based on their chemical structure. Heading 2910 specifically covers epoxides, epoxyalcohols, epoxyphenols, and epoxyethers with a three-membered ring. Ethylene oxide, also known as oxirane, is the simplest epoxide, consisting of two carbon atoms and one oxygen atom in a cyclic structure. For a product to be classified here, it must be a pure substance, although it may contain impurities resulting from the manufacturing process or stabilizers added for safety during transport. Ethylene oxide is a highly reactive, colorless gas at room temperature and serves as a critical intermediate in the production of ethylene glycol, surfactants, and various detergents. Its classification is determined by its specific chemical identity as a cyclic ether with a three-membered ring, which is explicitly named in the subheading 2910.10.

Products Included

• Pure ethylene oxide (oxirane)
• Ethylene oxide containing manufacturing impurities
• Ethylene oxide stabilized with small amounts of additives for transport safety
• High-purity ethylene oxide for chemical synthesis

Common Misclassification

Ethylene oxide is frequently confused with HS code 3824.81. The primary distinction is that 2910.10 is for the pure chemical compound, while 3824.81 is for chemical mixtures containing ethylene oxide, such as those used for industrial sterilization. It is also sometimes misclassified under 2901.21, which is the code for ethylene gas; however, ethylene oxide is a derivative (an epoxide) and must be classified in 2910. Furthermore, if the product is prepared as a disinfectant and put up in retail packaging, importers might mistakenly look at 3808.94, but 2910.10 remains the correct code for the bulk chemical.

FAQ

What is the HS code for Ethylene oxide?

The HS code for pure ethylene oxide is 2910.10, classified under the category of epoxides with a three-membered ring.

Can ethylene oxide be classified in Chapter 38?

Yes, but only if it is part of a mixture. If ethylene oxide is blended with inert gases like carbon dioxide for use as a fumigant or sterilant, it moves to HS code 3824.81.
