HS Code for PVDC resin

PVDC resin, or polyvinylidene chloride, is classified under HS code 3904.50. This classification falls under Heading 3904, which encompasses polymers of vinyl chloride or other halogenated olefins in primary forms. While PVC (polyvinyl chloride) is the most common polymer in this heading, PVDC is a distinct chemical entity characterized by the presence of two chlorine atoms on every other carbon atom in the polymer chain. Subheading 3904.50 specifically identifies vinylidene chloride polymers. Like other resins in this chapter, it must be in a primary form—such as powder, granules, or flakes—to qualify for this code. PVDC is highly valued for its exceptional barrier properties against moisture and oxygen, and its specific classification ensures that it is distinguished from standard PVC resins during the customs entry process. This distinction is vital for both regulatory compliance and duty rate application.

Products Included

• PVDC homopolymer resin
• Vinylidene chloride-vinyl chloride copolymers (where PVDC predominates)
• PVDC granules for extrusion
• PVDC aqueous dispersions (primary form)
• PVDC powder for coating applications

Common Misclassification

PVDC resin is most frequently misclassified as standard PVC resin (HS code 3904.10) due to the similarity in their names and chemical families. Another common error is classifying PVDC film or sheets under this code; however, finished film products should be classified under HS code 3920.49 or 3920.99 depending on the plasticizer content and structure. It is also important not to confuse PVDC with other halogenated polymers like PTFE, which falls under 3904.61.

FAQ

What is the HS code for PVDC resin?

The HS code for vinylidene chloride polymers (PVDC) in primary forms is 3904.50.

Is PVDC film classified under this code?

No, HS code 3904.50 is only for the resin in primary forms. PVDC film is typically classified under heading 3920 as a plate, sheet, or film.
