U.S. imports of nonplasticized pvc mixed with other substances, in primary forms (SITC 57312) totaled $2.4M in April 2026, traded with 16 countries.
Importers of Nonplasticized PVC Mixed with Other Substances, in Primary Forms paid $171K in duties in April 2026 — an effective duty rate of 16% on $1.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataRigid PVC compound — PVC resin blended with stabilizers, lubricants, impact modifiers, or other additives but without plasticizers — is the form most directly used in pipe, window profile, and rigid sheet extrusion without further compounding by the processor. The nonplasticized designation is commercially significant because it signals a rigid end-use profile, distinguishing this material from flexible PVC compounds that contain plasticizers. Importers should confirm that the additive package does not include plasticizers, as that would shift classification to a different heading covering plasticized mixed PVC.

Laboratory analysis of the additive package — specifically testing for phthalate or other plasticizer content — is the definitive method. Importers should provide a full formulation disclosure or certificate of analysis listing all additives and their concentrations; a declaration that no plasticizers are present supports the nonplasticized classification but may be subject to CBP verification.
Unmixed PVC requires the importer or a downstream compounder to add stabilizers and other additives before processing, while nonplasticized mixed PVC compound is ready for direct extrusion or molding. The choice affects supply-chain complexity, inventory management, and the ability to customize formulations — factors that often determine whether a processor imports base resin or finished compound.
