CAS number, grade, assay, and impurity profile
SDS, COA, TDS, HS code, and transport classification
Destination-market import documents before supplier matching
Package and route
Packing notes
Advertised packaging: 25 kg cardboard drums with inner aluminum foil bags
Alternative listing mentions 10 kg or 25 kg drums; confirm available commercial pack sizes before RFQ
Sample availability is advertised as 10 g to 20 g; confirm sample charge, courier terms, and sample COA availability
Request lot-coded packaging with intact inner liner, tamper-evident sealing if required, and export carton/drum marking details
Confirm moisture protection, palletization, container loading plan, and whether food-contact packaging declarations are available
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
Thickener or stabilizer ingredient qualification for food formulations
Film-forming polysaccharide for edible coating or capsule-related applications, subject to grade approval
Binder or excipient candidate review where supplier documentation meets buyer requirements
Water-soluble polysaccharide sourcing for sauces, dressings, coatings, confectionery, and baked goods
Sample testing for viscosity, clarity, film strength, solubility, and compatibility in buyer formulations
How we compare
Sourcing options
Request pre-shipment sample with COA for lab qualification before bulk order
Compare food-grade versus pharma-grade documentation and impurity specifications
Ask for latest production lot with full microbiological and heavy metal test results
Confirm 1 kg trial pack, 10 kg drum, and 25 kg drum options for pilot and commercial scale
Use third-party inspection or pre-shipment testing for identity, viscosity, moisture, microbial limits, and contaminants
Obtain destination-market document pack before confirming purchase order
Human review
Compliance notes
Request COA, SDS, TDS/specification sheet, allergen statement, GMO status, residual solvent statement if applicable, heavy metals report, microbiological report, and certificate of origin
For food applications, confirm compliance target by destination market, such as EU, US, GCC, ASEAN, Japan, or customer-specific standard; supplier claims should be independently reviewed
For pharmaceutical or excipient use, request applicable excipient documentation, GMP statement if available, residual impurity profile, and change-control policy
DG/export awareness: Pullulan powder is generally expected to ship as a non-dangerous dry ingredient, but buyer must confirm with the latest SDS and transport classification before shipment
HS Code listed as 2924 appears inconsistent for a polysaccharide ingredient; buyer should confirm correct HS code with customs broker and supplier export documents
Verify whether the product is animal-origin-free, halal/kosher certified within valid scope, and suitable for the buyer’s formulation and market requirements
No regulatory approval, end-use compliance, or import clearance is assumed from the marketplace listing alone
