Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3921.12.11.00Lower: 41.7% vs 44%

If density >0.92 g/cm³ making it rigid

Rigid PVC sheets shift to specific rigid plastic subheading based on physical properties.

3920.43.50.00Lower: 41.7% vs 44%

If contains >20% plasticizers

Subheading 3920.43 covers noncellular polymers with plasticizers; Chapter notes define plasticizers explicitly.

3921.90.11.00Lower: 41.7% vs 44%

If noncellular/non-foamed PVC

Lacks cellular structure, moving to noncellular plates/sheets of other plastics.

Import Tips & Compliance

• Verify cellular structure via density testing (<0.92 g/cm³) to confirm non-rigid status

• Provide manufacturer specs on polymer content; PVC must predominate per Chapter 39 notes
