HS Code for Polyvinylidene chloride
Polyvinylidene chloride (PVDC) is classified under HS code 3904.50. This classification is determined by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically Rule 1, which states that classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 39 covers plastics and articles thereof. Heading 3904 specifically addresses polymers of vinyl chloride or of other halogenated olefins, in primary forms. Within this heading, subheading 3904.50 is reserved for vinylidene chloride polymers. The term "primary forms" is strictly defined in Note 6 to Chapter 39, referring to liquids and pastes (including dispersions and solutions), or blocks of irregular shape, lumps, powders, granules, flakes, and similar bulk forms. PVDC is a synthetic resin produced by the polymerization of vinylidene chloride. It is highly valued in industrial applications for its exceptional barrier properties against water, oxygen, and aromas. To be classified here, the polymer must contain at least 95% by weight of vinylidene chloride monomer units, or it must be a copolymer where vinylidene chloride is the predominant monomer compared to other halogenated olefins. This technical distinction is vital for customs compliance and ensuring the correct duty rates are applied during international transit.

Common Misclassification
HS code 3904.10 (PVC) is often confused with PVDC; however, 3904.10 is specifically for poly(vinyl chloride) not mixed with any other substances. Another common error is using 3920.43, which covers plates, sheets, and film of non-cellular polymers of vinyl chloride. These are finished articles rather than primary forms. Additionally, 3904.61 for polytetrafluoroethylene (PTFE) is sometimes used incorrectly for other halogenated polymers.
