Products classified under HTS 3905.30.00.00
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.
Partially Hydrolyzed PVA 1788 Resin
PVA 1788 resin features 88% hydrolysis, containing notable unhydrolyzed acetate groups, making it suitable for packaging films and paper coatings. This primary form polymer is imported as free-flowing powder. It qualifies for HTS 3905.30.00.00 due to its explicit inclusion of poly(vinyl alcohol) with unhydrolyzed acetate groups.
High Viscosity PVA 0588 Powder
PVA 0588 is a low-hydrolysis (88%), high-viscosity grade used in emulsifiers and binders, containing unhydrolyzed acetate groups as per specification. Delivered in primary powder form for dissolution in water-based systems. Falls under HTS 3905.30.00.00 for poly(vinyl alcohol) variants.
PVA 117 Fully Hydrolyzed Granules
PVA 117 granules offer full hydrolysis (99%+) with trace unhydrolyzed acetate, ideal for textile sizing and ceramics. Primary form granules dissolve readily in hot water. HTS 3905.30.00.00 covers this as poly(vinyl alcohol) in granular primary form.
Industrial PVA B-15 Emulsion Base
PVA B-15 is a medium-hydrolysis grade (approx. 88%) for emulsion paints and adhesives, with unhydrolyzed acetate groups retained. Supplied as dry powder in primary form for factory compounding. Classified in HTS 3905.30.00.00 per the heading's inclusive definition.
Pharmaceutical Grade PVA 26-88
PVA 26-88 meets USP standards with 88% hydrolysis and controlled acetate groups, used in drug capsules and eye drops. Primary powder form for pharmaceutical compounding. HTS 3905.30.00.00 applies as it's poly(vinyl alcohol) whether containing unhydrolyzed acetate.
PVA 24-88 Textile Sizing Polymer
Specialty PVA 24-88 with 88% hydrolysis for warp sizing in cotton weaving, featuring acetate groups for adhesion. Imported as primary white powder. Fits HTS 3905.30.00.00 definition perfectly.
Low Molecular Weight PVA 03-80
PVA 03-80 offers low viscosity and 80% hydrolysis with higher acetate content, for specialty coatings and lubricants. Primary granular form. HTS 3905.30.00.00 covers all PVA variants including this.
Super-High Viscosity PVA 49-88
PVA 49-88 provides exceptional thickening with 88% hydrolysis, used in construction mortars and ceramics. Primary powder with acetate groups. Classified under 3905.30.00.00 as specified.
