Last updated: August 2026 dataEpoxide resins—widely known as epoxy resins—are thermosetting polymers that cure with hardeners to produce coatings, adhesives, laminates, and composite matrices used in aerospace, electronics, and construction. South Korea and Germany are the leading US import sources, with Japan and Canada also supplying significant volumes. All US imports enter under a single 10-digit line (3907300000), but the commercial product range is wide: liquid bisphenol-A epoxies, solid grades, and specialty novolac or cycloaliphatic types each serve distinct end-use specifications. Importers sourcing from certain origins should verify whether Section 301 or antidumping measures apply to their specific supply chain.

No; heading 3907.30 covers epoxide resins in all primary forms, including liquid, semi-solid, and solid grades. The distinction between liquid and solid grades matters commercially for pricing and end-use qualification but does not create separate HTS lines at the 10-digit level under this heading.
Primary forms include granules, powders, flakes, liquids, and similar undivided forms as defined in Chapter 39 Note 6. A pre-formulated two-component system already mixed with a hardener may no longer qualify as a primary form and could be reclassified as a prepared adhesive or coating under a different chapter. Importers should confirm the product's state at time of importation with a licensed customs broker.
