HS Code for Phenolic resin

Phenolic resins in primary forms are classified under HS code 3909.40. This code falls within Chapter 39, which covers plastics and articles thereof. Heading 3909 specifically addresses amino-resins, phenolic resins, and polyurethanes in primary forms. 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. Phenolic resins are thermosetting polymers produced by the condensation of phenol or a substituted phenol with an aldehyde, most commonly formaldehyde. This classification is essential for distinguishing raw polymer materials from semi-finished or finished plastic products. The chemical identity of the resin, whether it is a novolac (acid-catalyzed) or a resol (base-catalyzed), does not change the 3909.40 classification as long as the material remains in a primary form and has not been further worked into a specific shape.

Products Included

• Novolac resins in powder or flake form
• Resol resins in liquid or solution form
• Phenol-formaldehyde resins
• Modified phenolic resins in primary forms

Common Misclassification

A frequent misclassification occurs between 3909.40 and 3824.99 (prepared binders for foundry moulds). If the phenolic resin is mixed with specific additives that make it a prepared binder rather than a raw plastic, it may move to Chapter 38. Additionally, phenolic resins already shaped into sheets or plates are classified under 3920.94 or 3921.90, depending on whether they are reinforced or laminated. Importers often mistakenly use the resin code for finished plastic components.

FAQ

What is the HS code for phenolic resin?

Phenolic resins in primary forms, such as liquids, powders, or granules, are classified under HS code 3909.40.

Are phenolic molding compounds included here?

Yes, phenolic molding compounds consisting of the resin mixed with fillers (like wood flour or mineral fibers) are still considered primary forms under 3909.40.
