U.S. exports of Polyvinyl Chloride (PVC), Unmixed, in Primary Forms (SITC 57311) totaled $207.3M in August 2026.
Importers of Polyvinyl Chloride (PVC), Unmixed, in Primary Forms paid $1.1M in duties in August 2026, an average duty rate of 5.00% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataUnmixed PVC resin — produced without plasticizers, stabilizers, or other compounding additives — represents the base polymer as it exits the polymerization reactor, typically as a fine white powder. This form is the starting point for downstream compounders who add plasticizers and stabilizers to produce flexible or rigid PVC compounds tailored to specific applications such as wire insulation, flooring, or medical tubing. The unmixed designation is a critical classification boundary: any addition of processing aids or stabilizers before export shifts the material to a mixed-PVC heading.

The resin must be the pure polymer without deliberate addition of plasticizers, stabilizers, fillers, or other compounding ingredients. Trace residuals from the polymerization process (such as residual monomer or water) do not disqualify the material, but any intentional additive package — even a heat stabilizer added for processing — moves the product to the mixed-PVC heading.
Suspension, emulsion, and bulk (mass) polymerization are the three main commercial processes. Suspension PVC is the most widely traded form for rigid applications; emulsion PVC (paste resin) is used for plastisol applications. The polymerization process does not itself change the SITC heading, but it affects particle size and porosity, which are key purchasing specifications that buyers should confirm with suppliers.
