HS Code 29.10 – Epoxides, epoxyalcohols, epoxyphenols and epoxyethers; with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives

HS code 2910 is a 4-digit heading in the Harmonized System that covers: Epoxides, epoxyalcohols, epoxyphenols and epoxyethers; with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives. Heading 2910 is dedicated to epoxides, epoxyalcohols, epoxyphenols, and epoxyethers that specifically feature a three-membered ring (oxirane ring), along with their halogenated, sulphonated, nitrated, or nitrosated derivatives. This classification is crucial for chemically defined organic compounds that contain this highly reactive cyclic ether structure. The oxirane ring's reactivity makes these compounds invaluable as monomers for epoxy resins, starting materials for polyols, and intermediates in the synthesis of various fine chemicals. The scope strictly includes only compounds with the three-membered epoxide ring, distinguishing them from other cyclic ethers (2909) or polymers (Chapter 39). Accurate classification under 2910 is paramount for trade compliance due to the often-toxic, flammable, or explosive nature of many epoxides, necessitating strict adherence to hazardous materials regulations, specific tariff rates, and environmental controls. Historically, epoxides, particularly ethylene oxide and propylene oxide, have been fundamental building blocks in the petrochemical industry since the mid-20th century, enabling the vast production of plastics, detergents, and other industrial chemicals. This heading reinforces Chapter 29's focus on distinct organic chemical entities.

Ethylene oxide, Propylene oxide, Epichlorohydrin, Styrene oxide, Glycidol, 1,2-Epoxybutane, Cyclohexene oxide, Diglycidyl ether of bisphenol A (DGEBA), Triglycidyl isocyanurate (TGIC), Methyl glycidyl ether, Phenyl glycidyl ether, 3-Chloro-1,2-epoxypropane, Butylene oxide, 1,4-Butanediol diglycidyl ether, Vinyl cyclohexene dioxide, Limonene dioxide, 2,3-Epoxy-1-propanol, Glycidyl methacrylate, Epoxysuccinic acid, 3-Glycidyloxypropyltrimethoxysilane

Common misclassifications under HS 2910 include confusing epoxides with other cyclic ethers (2909) that do not possess the three-membered oxirane ring. Another frequent error is classifying polymers of epoxides, particularly epoxy resins, under 2910 instead of Chapter 39 (e.g., 3907 for polyethers, polyacetals, epoxy resins). Traders might also incorrectly classify other halogenated organic compounds (2903) that are not epoxides. The key differentiator for 2910 is the presence of the three-membered epoxide ring. Misclassifying these highly reactive and often hazardous chemicals can lead to severe penalties, incorrect duty assessments, and non-compliance with international safety standards.

In 2025, the top exporters of HS code 2910 in UN Comtrade data were Germany ($521M, 18% of world exports), the Netherlands ($501M) and the United States ($484M). World exports came to about $2.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 2910 in UN Comtrade data were the Netherlands ($665M, 21% of world imports), Germany ($448M) and Belgium ($391M). World imports came to about $3.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 2910 is a 4-digit heading under Chapter 29 of the Harmonized System. The first 2 digits (29) identify the chapter, and digits 3-4 (10) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
