Epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring, and their halogenated, sulfonated, nitrated or nitrosated derivatives
8 declarable lines
Heading 2910 covers epoxides, epoxyalcohols, epoxyphenols and epoxyethers that contain a three-membered epoxide ring, plus their halogenated, sulfonated, nitrated or nitrosated derivatives. The heading is split first by specific named chemicals (oxirane, methyloxirane, epichlorohydrin, dieldrin, endrin) and then by a residual Other group that separates butylene oxide, aromatic epoxides, and all remaining products.
Products in this heading
- Ethylene oxide (oxirane) used as a chemical intermediate and sterilant
- Propylene oxide (methyloxirane) for polyether polyols and propylene glycol
- Epichlorohydrin for epoxy resins and synthetic glycerin
- Dieldrin technical material
- Endrin technical material
- Butylene oxide
- Aromatic epoxy resins based on bisphenol A diglycidyl ether
How to choose the right subheading
- Confirm the molecule contains a three-membered epoxide ring; without that ring the product belongs elsewhere.
- Check whether the product is one of the five specifically named compounds and use its dedicated line.
- If it is not named, decide whether it is butylene oxide, an aromatic epoxide, or another epoxide.
- Check for halogen, sulfonate, nitrate or nitroso groups, since derivatives of these epoxides stay in the heading.
- Distinguish epoxides from ordinary ethers, which are classified in heading 2909.
Often confused with
- Heading 2907Bisphenol A (diphenylolpropane)
It is a phenol-alcohol with no three-membered epoxide ring.
- Heading 2916Glycidyl methacrylate
It is an unsaturated acyclic monocarboxylic acid ester, classed by the acid function.
- Heading 2932Tetrahydrofuran
It is a cyclic ether with a five-membered ring, not a three-membered epoxide.
- Heading 2815Sodium hydroxide for resin curing
It is an inorganic base, not an organic epoxide.
Frequently asked questions
What is the HTS code for ethylene oxide?
Ethylene oxide (oxirane) is classified under 2910.10.00.00, with a general (MFN) rate of 5.5%.
What is the duty on epichlorohydrin?
Epichlorohydrin (1-chloro-2,3-epoxypropane) falls under 2910.30.00.00 and pays a general (MFN) rate of 3.7%.
How do I classify an aromatic epoxy resin?
Aromatic epoxides that are not specifically named go under 2910.90.20.00 at a general (MFN) rate of 5.5%; butylene oxide goes under 2910.90.10.00 at 4.6%, and other residual epoxides under 2910.90.91.00 at 4.8%.
