Medium-density polyethylene pellets have a density range of 0.926-0.941 g/cm³, used for pipe and film production. Classified in 3901.90.90.00 as 'other' ethylene polymers not qualifying for specific density-based subheadings like LDPE or HDPE. Subheading notes dictate classification by predominant monomer when not fitting named polymers.

Import Tips
• Include density test certificates (ASTM D1505) to distinguish from 3901.20 LDPE during Customs review
• Ensure declaration specifies 'primary forms only' to prevent confusion with finished goods in 3921-3926
• Watch for copolymer content; if >5% comonomer predominates, reclassify per note (a)(4)
