Polyvinylidene Chloride (PVDC) Resin
Polyvinylidene chloride resin is a primary form homopolymer where vinylidene chloride monomer constitutes 95% or more by weight, used primarily for its exceptional barrier properties against oxygen and moisture. It falls under HTS 3904.50.00.00 as a vinylidene chloride polymer in primary forms such as pellets or granules. This classification follows chapter notes specifying polymers named by 'poly' prefix with predominant monomer content.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copolymer with vinyl chloride predominant
Classified by predominant monomer under subheading note (a)(4); vinyl chloride unit exceeds vinylidene chloride by weight.
If blends or copolymers not meeting 95% threshold
Falls to 'Other' polymers of vinyl chloride/other halogenated olefins if no specific prefix matches per chapter notes.
If chemically modified beyond simple variants
Chemically modified polymers go to 'Other' if not specifically covered, per subheading note (a)(3).

Import Tips & Compliance
• Verify monomer content exceeds 95% vinylidene chloride via lab analysis to meet subheading note (a)(1); provide certificates of analysis from manufacturer
• Common pitfall: misclassifying copolymers with less than 95% as other polymers
• Label clearly as primary form (pellets/granules), not compounded products

Saran Resin Pellets
Saran resin pellets are granular primary forms of polyvinylidene chloride homopolymer, trademarked for food packaging films due to high gas barrier properties. Classified under HTS 3904.50.00.00 as vinylidene chloride polymers meeting the 95% monomer rule in primary forms. Not for end-use articles like films, which shift to Chapter 39 headings like 3920.
Vinylidene Chloride Homopolymer Granules
Granules of vinylidene chloride homopolymer in primary form for extrusion into barrier films, with vinylidene chloride at 97% by weight. HTS 3904.50.00.00 covers these as it specifies polymers where the named monomer dominates per chapter subheading note (a)(1). Used in meat wrap and medical packaging.
PVDC Copolymer Pellets 96% VDC
Pellets of copolymer with 96% vinylidene chloride and minor methyl acrylate for flexibility, still classified as vinylidene chloride polymer under HTS 3904.50.00.00 per note (a)(1) prefix rule. Primary form for converting to coextruded films.
Barrier Grade PVDC Resin
High-barrier grade PVDC resin in primary pellet form, 98% vinylidene chloride, for pharmaceutical blister packaging. Falls squarely under HTS 3904.50.00.00 as primary vinylidene chloride polymer per strict 95% monomer criterion in chapter notes.
