Celcon Polyacetal Copolymer Pellets
Celcon is a commercial polyacetal copolymer resin designed for acetal applications, classified here as polyacetals where acetal units predominate over other comonomers per subheading note (a)(4). Primary form granules for molding gears and bushings. Falls under 3907.10.00.00 due to polyacetal base.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polyacetal content below predominance threshold with other polyesters
Blends not predominantly polyacetal shift to 'Other polyesters' in 3907.99 per subheading note (a)(4).
If for polyvinyl chloride copolymers if comonomer analysis shifts predominance
Classification follows monomer unit that predominates by weight over others in the series.
If imported as pre-molded plates or sheets, not primary pellets
Plates, sheets, and other shapes of plastics are classified in 3920, not primary forms.

Import Tips & Compliance
• Submit detailed polymer composition breakdown to prove acetal units predominate by weight
• Label shipments clearly as 'primary form polyacetals' to prevent confusion with finished articles
