Baking Phenolic Resin
Baking phenolic resin is a heat-curable resin derived from phenol-formaldehyde condensation, designed for stoving applications in paints and coatings. It is imported in primary form, such as liquid or powder, and falls under this tariff item as a phenolic resin.
3909.40.00Bisphenol A Phenolic Resin
Bisphenol A phenolic resin substitutes bisphenol for phenol in applications similar to epoxy, but remains a phenolic resin. It is imported in primary form and classified here because phenolic units predominate in the polymer structure.
3909.40.00Creol Phenolic Resin
Creol phenolic resin, also known as cresol-formaldehyde resin, uses cresol instead of phenol for enhanced flexibility in coatings. It falls under this tariff item as phenolic resins include alkyl-substituted phenols like cresol.
3909.40.00Foundry Grade Phenolic Urethane Resin Binder
Foundry grade phenolic urethane resin binder is the pure phenolic resin component of a two-part foundry binder system, used for sand cores in no-bake casting. It is imported in primary form and classified here as a phenolic resin.
3909.40.00High Ortho Phenolic Resin
High ortho phenolic resin features high ortho substitution for faster curing in laminates, produced via specialized catalysis. It falls under this tariff item as an unmodified phenolic primary polymer used in copper-clad laminates.
3909.40.00Liquid Phenolic Resol for Adhesives
Liquid phenolic resol resin is a primary form polymer for plywood and laminate adhesives, reacting phenol with excess formaldehyde. It is classified here as a phenolic resin in primary form, meeting Chapter 39 requirements.
3909.40.00Novolac Phenolic Resin
Novolac phenolic resin is a thermosetting polymer produced by reacting phenol with formaldehyde under acidic conditions, requiring a hardener for curing. It falls under this tariff item as a phenolic resin in primary form.
3909.40.00Phenol-Formaldehyde Molding Compound Base Resin
Phenol-formaldehyde molding compound base resin is the pure resin used as the base for molding compounds, supplied in primary form before fillers are added. It falls under this tariff item as a phenolic resin, with strict monomer weight rules applied.
3909.40.00Powdered Novolac Resin for Friction Materials
Powdered novolac resin for friction materials is ground phenolic polymer for brake pads and clutch facings, cured with hexamine. It falls under this tariff item as a primary phenolic resin before compounding, providing heat resistance.
3909.40.00Resol Phenolic Resin
Resol phenolic resin is a liquid or semi-solid thermosetting resin formed by base-catalyzed reaction of phenol and formaldehyde, self-curing upon heating. It is classified under this tariff item as a primary form phenolic resin.
