U.S. imports of polyvinyl alcohol, with or without unhydrolyzed acetate groups (HS 390530) totaled $10.2M in April 2026, traded with 14 countries.
Importers of Polyvinyl Alcohol, With or Without Unhydrolyzed Acetate Groups paid $1.5M in duties in April 2026 — an effective duty rate of 14% on $10.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Polyvinyl Alcohol, With or Without Unhydrolyzed Acetate Groups imports of $10.2M in April 2026 ran 15% above the year-to-date monthly average of $8.8M.
Last updated: April 2026 dataPolyvinyl alcohol (PVA or PVOH) — produced by hydrolysis of polyvinyl acetate and classified under a single US tariff line (3905300000) — is a water-soluble polymer critical to the production of optical films for LCD displays, textile warp sizing, paper coatings, and water-soluble packaging. Taiwan and Japan together dominate US import supply, a concentration that reflects the deep integration of PVOH production with East Asian electronics and textile manufacturing ecosystems. Degree of hydrolysis (fully vs. partially hydrolyzed) and degree of polymerization are the key specification parameters that determine end-use suitability and should be documented on the commercial invoice.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
No — heading 390530 explicitly covers polyvinyl alcohols 'whether or not containing unhydrolyzed acetate groups,' so both fully and partially hydrolyzed grades classify here. However, degree of hydrolysis is commercially critical and should be stated on the invoice and technical documentation to avoid disputes over product identity or valuation.
The commercial invoice should reference the supplier's product grade designation, degree of hydrolysis (expressed as mol% or wt%), and viscosity grade (which correlates to molecular weight). A manufacturer's certificate of analysis or technical data sheet accompanying the shipment provides the supporting evidence CBP may request during examination.
