Pure Alkyd Resin 100% Solids
A high-solids alkyd resin derived from polycondensation of polyols, phthalic anhydride, and drying oils like linseed oil, used as a primary form binder in paints. Classified under HTS 3907.50.00.00 as an alkyd resin in primary forms, meeting the chapter note criteria for polymers where the core alkyd structure predominates by weight.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dissolved in solvents for direct paint use
Solvent-based varnishes and lacquers, including alkyd paint bases, are classified in Chapter 32 based on use rather than polymer type.
If chemically modified with significant non-alkyd comonomers
Unsaturated polyesters not qualifying as pure alkyds fall under other polyester subheadings per subheading note (a)(3) and (4).
If imported as prepared paint binder blend
Mixtures of polymers exceeding simple alkyd predominance are chemical preparations in Chapter 38.

Import Tips & Compliance
• Verify monomer composition meets 95% alkyd structure per subheading note (a)(1) to avoid reclassification; provide technical data sheets confirming primary form (not dissolved)
• Common pitfall: importing pre-mixed paint formulations, which shift to Chapter 32
