Phenol-Formaldehyde Molding Compound Base Resin
This is the pure phenol-formaldehyde resin used as the base for molding compounds, supplied in primary form before fillers are added. HTS 3909.40.00.00 covers it as phenolic resin, with strict monomer weight rules applied. Essential for producing electrical components and handles.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If styrene copolymer blends
If styrene comonomer predominates, classifies under styrene polymers.
If after compounding with fillers
Fully compounded molding materials become articles of agglomerated materials.
If other amino-phenolic hybrids
Hybrids not purely phenolic go to other polymers in the amino/phenolic heading.

Import Tips & Compliance
• Provide chromatograph analysis showing 95%+ phenolic units
• Ensure no fillers present to maintain primary form status
• Pitfall: importing as 'resin powder' mistaken for compounded material

Novolac 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 HTS 3909.40.00.00 as a phenolic resin in primary form, typically supplied as granules or powder for molding compounds. Used primarily in electrical insulators and abrasives due to its heat resistance.
Resol 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. Classified under HTS 3909.40.00.00 as it is a primary form phenolic resin used in laminates and coatings. Its high reactivity suits adhesives and foundry applications.
Baking Phenolic Resin
Baking phenolic resin is a heat-curable resin designed for stoving applications in paints and coatings, derived from phenol-formaldehyde condensation. It is imported in primary form under HTS 3909.40.00.00, meeting the polymer classification rules for phenolic resins. Commonly used in appliance coatings for durability.
Liquid Phenolic Resol for Adhesives
Liquid phenolic resol resin is a primary form polymer for plywood and laminate adhesives, reacting phenol with excess formaldehyde. Classified in HTS 3909.40.00.00 due to its phenolic resin composition meeting Chapter 39 polymer rules. High tack and bonding strength make it ideal for wood industry.
Creol Phenolic Resin
Creol phenolic resin, also known as cresol-formaldehyde resin, uses cresol instead of phenol for enhanced flexibility in coatings. It qualifies under HTS 3909.40.00.00 as phenolic resins include alkyl-substituted phenols in primary forms. Used in can coatings and electrical laminates.
Powdered Novolac Resin for Friction Materials
Powdered novolac resin is ground phenolic polymer for brake pads and clutch facings, cured with hexamine. HTS 3909.40.00.00 applies as primary phenolic resin before compounding. Provides heat resistance in automotive friction applications.
