HS Code for Polyurethane

Polyurethanes in primary forms are classified under HS code 3909.50. This classification follows the nomenclature of Chapter 39, which encompasses plastics and resins. Heading 3909 specifically includes amino-resins, phenolic resins, and polyurethanes. The subheading 3909.50 is the specific international designation for polyurethanes. These materials are characterized by the presence of the urethane group in the polymer chain, typically formed by the reaction of polyisocyanates with polyols. To qualify for this code, the material must be in a primary form, such as granules, pellets, or liquid resins, and must not have been further processed into finished articles or semi-manufactured shapes like sheets or tubes. This code is essential for the trade of raw plastic materials used in everything from automotive parts to coatings.

Products Included

• Thermoplastic polyurethane (TPU) granules
• Polyurethane prepolymers
• Linear polyurethanes in liquid form
• Cross-linked polyurethanes in primary forms

Common Misclassification

A common error is classifying polyurethane coatings under 3909.50. If the polyurethane is dissolved in a volatile organic solvent and the solvent exceeds 50% of the weight, it must be classified under HS code 3208.90. Furthermore, finished polyurethane foam products are often confused with the raw resin; however, cellular polyurethane sheets belong under 3921.13, not 3909.50.
