Division 3 Headings 3901 to 3911 apply only to goods of a kind produced by chemical synthesis, falling in the following categories:

liquid synthetic polyolefins of which less than 60 % by volume distils at 300 °C, after conversion to 1 013 mbar when a reduced-pressure distillation method is used (headings 3901 and 3902);

resins, not highly polymerised, of the coumarone-indene type (heading 3911);

other synthetic polymers with an average of at least five monomer units;

silicones (heading 3910);

resols (heading 3909) and other prepolymers.
