3904.10.00.00 - Poly(vinyl chloride), not mixed with any other substances 🖩

This HTS classification, 3904.10.00.00, specifically covers poly(vinyl chloride) (PVC) in its primary forms, where it is *not* mixed with any other substances. This means that the material, at this stage of classification, consists solely of PVC polymers without the addition of plasticizers, stabilizers, fillers, pigments, or other additives that would alter its fundamental chemical composition or intended processing characteristics for further manufacturing. Examples include PVC resins, powders, granules, or blocks that are essentially pure PVC.

This category is distinguished from its sibling categories by its strict requirement of containing only PVC. For instance, it is distinct from "Other poly(vinyl chloride)" which may encompass PVC blended with minor quantities of other substances. Furthermore, it differs from copolymer classifications such as vinyl chloride-vinyl acetate copolymers (3904.30) and other vinyl chloride copolymers (3904.40.00.00), as these involve the polymerization of vinyl chloride with other monomers, resulting in distinct material properties. Similarly, vinylidene chloride polymers (3904.50.00.00) and fluoropolymers represent entirely different polymer families.

As this is a leaf node, there are no further subdivisions within this specific classification. Therefore, the classification hinges on the absolute purity of the PVC. Any addition of other substances, even in small percentages that might typically be considered an additive in a final product, would necessitate classification under a different subheading that accounts for those co-components or modifications. The focus here is on the foundational, unadulterated PVC polymer.
