Headings 2304–2306 specifically cover residues from soybean, peanut, and other vegetable oil extraction. Heading 2308 is the residual provision for vegetable feed materials not captured by those headings or by heading 2309 (prepared animal feeds). If the material results from oil extraction, classify it in the appropriate oilcake heading; if it is a formulated preparation, consider 2309; otherwise 2308 applies.

No. The heading text explicitly includes materials 'in pellets or not,' so pelleting for ease of handling and transport does not change the classification as long as the pellets consist solely of the vegetable waste material without added binders or nutritional preparations that would make them a prepared feed under 2309.
