Bisphenol A Diglycidyl Ether Epoxy Resin
A liquid epoxy resin composed primarily of bisphenol A and epichlorohydrin, classified under HTS 3907.30.00.00 as it consists of epoxide resins in primary forms with epoxide groups exceeding 0.2% by weight. Used as a base for adhesives, coatings, and composites.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mixed with curing agents or pigments
Epoxy formulations ready for application as paints or varnishes fall under Chapter 39 heading 3909, not primary resins.
If chemically modified or blended below 95% epoxide content
Per subheading note (a)(3)-(4), modified polymers or blends not predominantly epoxide go to 'Other chemical preparations'.
If aromatic polyether content predominates over epoxide
Classification follows predominant monomer unit per note (a)(4), shifting to other polyethers if epoxide <95%.

Import Tips & Compliance
• Verify monomer content meets 95% by weight for epoxide units per subheading note (a)(1) to avoid reclassification
• Provide technical data sheets confirming epoxide equivalent weight and primary form (not compounded)
