Alternative Classifications

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

3904.10.00.00Higher: 41.5% vs 35%

If vinyl chloride monomer predominates

Subheading hierarchy prioritizes predominant monomer; PVC copolymers shift to vinyl chloride polymers heading.

3920.99.20.00Higher: 39.2% vs 35%

If imported as finished noncellular plates/sheets

Finished plastic articles in plate/sheet form (not primary forms) move from Chapter 39 primary polymers to Chapter 39 plates/sheets heading.

3907.99Same rate: 35%

If blends not meeting 95% pure copolymer threshold

Fails specific LCP copolymer criteria under subheading note (a)(1), defaults to general aromatic polyester subheading.

Import Tips & Compliance

Document ESD properties and conductivity specifications separately from polymer classification

Ensure packaging prevents moisture absorption during ocean transit (use desiccant)

Classify based on base polymer, not additives like carbon fillers
