Polyvinyl Chloride (PVC) Homopolymer Resin K-67
PVC K-67 is a suspension-grade polyvinyl chloride homopolymer resin with a K-value of 67, used primarily in rigid applications like pipes and profiles. It falls under HTS 3904.10.00.00 because it is unmixed poly(vinyl chloride) where the vinyl chloride monomer units constitute 95% or more by weight of the total polymer content. This classification applies to pure PVC resins without any additives or copolymers.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If mixed with plasticizers or stabilizers
Blends or chemically modified PVC not meeting 95% pure vinyl chloride content fall into 'Other' polyvinyl chloride subheadings.
If processed into polyethylene instead
Material composition changes heading if the predominant monomer is ethylene rather than vinyl chloride per subheading note (a)(4).
If for copolymers with significant other monomers
Polymers not predominantly vinyl chloride are classified by the prevailing monomer unit under subheading note rules.

Import Tips & Compliance
• Verify purity certificate from manufacturer confirming no mixing with other substances or additives exceeding note (a)(1) thresholds; common pitfall is misclassifying PVC with stabilizers
• Ensure MSDS documentation complies with TSCA for chemical imports
• Label packages clearly with UN numbers for hazardous material handling if applicable
