Polyvinylidene Chloride (PVDC) Resin from Mexico
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.

Import Tips
• 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
