Applications and sourcing options

Check whether this product fits the buyer's actual application.

Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

Use context

Common applications

  • Binder or film-forming component in water-based coatings after formulation validation
  • Adhesive formulation raw material where specified viscosity and alcoholysis degree are required
  • Textile sizing and finishing applications requiring consistent water-soluble polymer performance
  • Dry mortar or construction additive systems where PVA grade compatibility has been tested
  • Paper processing and surface treatment applications requiring controlled ash and volatile content
  • Emulsion, dispersant, and protective colloid applications subject to buyer’s internal qualification
How we compare

Sourcing options

  • Request quotation for PVA 1788 / 088-20 in 25 kg bags with batch COA
  • Request quotation for PVA 2488 / 088-50 in 25 kg bags with viscosity-method confirmation
  • Request quotation for PVA 2499 / 100-60 in 25 kg bags for high alcoholysis requirements
  • Request mixed-grade sample set for lab comparison before bulk purchase
  • Request palletized export packing with English labels and pre-shipment document review
  • Request supplier comparison based on COA consistency, HS-code accuracy, SDS quality, and repeat-lot availability
Human review

Compliance notes

  • Request current SDS in English, COA, TDS/specification sheet, packing list, commercial invoice, and certificate of origin before shipment
  • Confirm CAS 9002-89-5 and exact PVA grade on COA, SDS, label, and customs documents
  • Verify HS code with broker; source page lists HS Code 9021900090, which appears inconsistent for a polymer resin and should be checked before import declaration
  • Confirm dangerous goods classification with the supplier’s SDS and freight forwarder; PVA resin is commonly shipped as non-DG, but shipment status must be document-based
  • Check destination-country polymer inventory or chemical notification requirements where applicable, including REACH, TSCA, UK REACH, K-REACH, IECSC, AICS/AIIC, DSL/NDSL, or local inventory obligations as relevant
  • For food, pharmaceutical, medical, or regulated-contact applications, request grade-specific compliance documents; do not assume suitability from general-purpose industrial PVA listing
  • Confirm absence or limits of restricted substances if required by buyer program, such as heavy metals, formaldehyde, phthalates, SVHC, residual monomers, or other controlled impurities
  • Export and import clearance should be reviewed by qualified compliance personnel; supplier marketplace labels are not a regulatory guarantee
