Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains plasticizers like phthalates
Subheading note includes secondary plasticizers, moving to plasticized PVC.
If ethylene-vinyl chloride copolymer predominates ethylene
Predominant monomer determines classification per subheading note (a)(4).
If pre-compounded with plasticizers for sheets
Compounded noncellular sheets of PVC shift to plates/sheets heading.

Import Tips & Compliance
• Use suspension polymerization certificates to prove homopolymer status
• Avoid contamination with plasticized grades during shipping to prevent duty disputes
• Declare exact K-value (viscosity index) for CBP verification of rigid grade specs
