Polyvinyl Alcohol (PVA) 1799 Grade
Polyvinyl alcohol (PVA) 1799 is a water-soluble synthetic polymer with a hydrolysis degree of approximately 99%, produced from polyvinyl acetate through hydrolysis, retaining minimal unhydrolyzed acetate groups. It is supplied in primary form as white granular powder for industrial use in adhesives and textiles. Classified under HTS 3905.30.00.00 as it meets the definition of poly(vinyl alcohol) in primary forms.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fully hydrolyzed with no unhydrolyzed acetate groups exceeding trace levels
Pure poly(vinyl acetate) without significant hydrolysis falls under the preceding subheading for vinyl acetate polymers.
If for chemically modified PVA with additives beyond simple acetate groups
Significant chemical modifications place it in 'other polymers' under Chapter 39 per subheading notes.
If when imported as prepared adhesive binder containing PVA
Formulated PVA adhesives are classified as prepared glues rather than primary polymers.

Import Tips & Compliance
• Verify hydrolysis degree and acetate content via lab testing to confirm classification under 3905.30; provide manufacturer's specification sheets showing monomer composition meets 95% PVA threshold
• Ensure proper labeling as 'primary form polymer' to avoid misclassification as finished articles
• Watch for copolymer blends exceeding acetate limits, which may shift to other vinyl polymer subheadings
