Explore global trade with HS codes

HS Code 3907 covers polyacetals, polyethers, epoxide resins, polycarbonates, alkyd resins, polyesters, and other specialized polymers in primary forms. The classification includes detailed subcategories for each polymer family (3907.10-3907.99). These engineering and specialty plastics offer enhanced performance characteristics compared to commodity plastics. Products are traded as granules, powders, or liquid resins for further processing. Technical requirements focus on mechanical properties, thermal stability, and purity for food-contact or medical applications. This division represents advanced polymer chemistry delivering specific performance attributes for demanding applications in electronics, automotive, construction, and packaging industries, forming the raw material basis for high-value plastic components appearing in later HS codes.
