Products classified under HTS 3907.91.20.00
Uncompounded Allyl Resin Diallyl Phthalate
Diallyl phthalate (DAP) resin in primary, uncompounded form is a thermosetting unsaturated polyester allyl resin used primarily for molding compounds in electrical insulators. It falls under HTS 3907.91.2000 as an uncompounded allyl resin, meeting the chapter note requirement where the allyl monomer units contribute over 95% by weight. This primary form is supplied as granules or powder before any additives or compounding.
Uncompounded Allyl Diglycol Carbonate Resin
Allyl diglycol carbonate (CR-39) resin in uncompounded primary form serves as the base material for optical lenses and eyewear. Classified under HTS 3907.91.2000 as it qualifies as an uncompounded allyl resin with allyl ester monomers dominating over 95% by weight per subheading notes. Supplied as liquid or syrup for casting processes.
Uncompounded Diallyl Isophthalate Allyl Resin
Diallyl isophthalate (DAIP) resin, an uncompounded allyl polyester in primary granular form, used in high-performance composites for aerospace. HTS 3907.91.2000 applies as the allyl monomer units exceed 95% by weight, fitting the 'allyl resins, uncompounded' specification exactly. Ideal for prepreg manufacturing.
Uncompounded Allyl Resin for Electrical Laminates
Specialty uncompounded allyl resin formulated for electrical grade laminates and circuit boards, supplied in primary powder form. Falls under HTS 3907.91.2000 because it is an uncompounded allyl polyester resin with >95% allyl content by chapter note (a)(1). Used in varnishing processes before sheet molding.
Pure Uncompounded Triallyl Cyanurate Resin
Triallyl cyanurate (TAC) allyl resin in uncompounded primary form, a cross-linking agent resin for rubbers and composites. HTS 3907.91.2000 covers this as allyl resin where allyl units constitute 95%+ by weight per polymer classification notes. Distributed as free-flowing powder.
Uncompounded Allyl Ester Polyester Resin Grade A
Industrial grade A uncompounded allyl ester polyester resin in primary flake form for molding electrical components. Precisely matches HTS 3907.91.2000 as uncompounded allyl resin with qualifying monomer content per subheading note (a). High purity for precision applications.
