HS Code for Epoxy resin

Epoxy resins are classified under HS code 3907.30 as epoxide resins in primary forms. Chapter 39 covers plastics and articles thereof, and heading 3907 includes polyacetals, other polyethers, and epoxide resins. The term "primary forms" is strictly defined in Note 6 to Chapter 39, referring to liquids and pastes, including dispersions and solutions, or blocks of irregular shape, lumps, powders, granules, flakes, and similar bulk forms. Epoxy resins are thermosetting polymers that contain epoxide groups. Their classification depends on their chemical state at the time of import; they must not be mixed with fillers, pigments, or other materials that would transform them into prepared glues or adhesives. If the resin is a pure polymer or a simple solution in an organic solvent (where the solvent does not exceed 50% of the weight), it remains in 3907.30.

Products Included

• Liquid epoxy resins (unmixed)
• Solid epoxy resins in flakes or powder
• Epoxide resins in primary forms for coatings
• Bisphenol A-based epoxy resins
• Novolac epoxy resins in primary forms

Common Misclassification

Epoxy resins are frequently misclassified under HS code 3506.91 if they are packaged as adhesives or glues. If the product is a two-part system (resin and hardener) put up for retail sale as an adhesive, it must be classified under 3506. Another common error is 3214.10, which covers painters' fillings and non-refractory surfacing preparations; this applies if the epoxy is already mixed with fillers for use as a putty.

FAQ

What is the HS code for liquid epoxy resin?

Liquid epoxy resin in its primary, unmixed form is classified under HS code 3907.30.

Does the HS code change if the resin is colored?

If the resin contains pigments and is prepared as a paint or enamel, it may move to Chapter 32. If it is just a masterbatch or slightly tinted resin in primary form, it usually stays in 3907.30.
