Subheadings
Products classified under Tariff item 3909.40
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 tariff item 3909.40.00 as a phenolic resin.
3909.40.00Bisphenol A Phenolic Resin
Bisphenol A phenolic resin substitutes bisphenol for phenol in epoxy-like applications but remains a phenolic resin. It is imported in primary form and classified under this tariff item when phenolic units predominate, used in advanced composites and coatings.
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 qualifies under this tariff item as phenolic resins include alkyl-substituted phenols, and it is imported in primary form.
3909.40.00Foundry Grade Phenolic Urethane Resin Binder
Foundry grade phenolic urethane resin binder is the pure phenolic resin component of two-part foundry binders, reacted with polyol for sand cores. It is imported in primary form and falls under this tariff item as a phenolic resin, enabling no-bake casting processes.
3909.40.00High Ortho Phenolic Resin
High ortho phenolic resin features high ortho substitution for faster curing in laminates, produced via specialized catalysis. It is an unmodified phenolic primary polymer, falling under this tariff item, and is 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 under this tariff item due to its phenolic resin composition, meeting Chapter 39 requirements for primary forms.
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, used in molding and coatings.
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. This tariff item covers it 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. This tariff item applies as it is a primary phenolic resin before compounding, providing heat resistance in automotive friction applications.
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, used in adhesives and coatings.
