Package and route
Packing notes
Listed packing: 25 kg/bag
Transport package listed as 25 kg/bag with paper packaging material
MOQ shown as 1,000 kg; sample availability mentioned but should be confirmed by lot, grade, and destination
Request palletization, liner type, moisture protection, batch labeling, and shelf-life statement before order placement
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.

Human review
Compliance notes
Confirm exact CAS, chemical name, grade, and specification for the selected alginate salt before using the offer for customs, SDS, registration, or label review
Ask for COA matching the offered batch, SDS, TDS/specification sheet, B/L, commercial invoice, packing list, and certificate of origin as applicable
Food, cosmetic, pharmaceutical, dental, or agrochemical use claims require destination-market review by the buyer and supporting supplier documents
Verify whether BRC, ISO, FDA, HACCP references apply to the manufacturer, product grade, facility, or documentation package
Check HS code 3913100000 and destination import requirements with broker before shipment
DG status is not established from the supplied text; request current SDS and transport classification before booking cargo
For agrochemical registration buyers, request impurity profile, residual solvent statement if applicable, heavy metals, microbiological limits where relevant, and batch-to-batch consistency data

Questions to confirm
Which exact product is being quoted: sodium alginate, calcium alginate, magnesium alginate, zinc alginate, or another alginate derivative?
What CAS number, EINECS number, molecular description, and grade apply to the requested alginate salt?
Can you provide a signed COA with viscosity method, moisture method, pH method, insolubles, ash, heavy metals, and microbiological limits if required?
Is the viscosity range customizable, and what tolerance is guaranteed per shipped batch?
What is the confirmed moisture limit, since the listing shows both 10% and 14.82%?
What impurity profile is available for registration or formulation evaluation?
Can you provide SDS, TDS, allergen/GMO/BSE-TSE statements, food-grade documents, or registration support documents where applicable?
What is the current lead time for 25 kg bags, 1 MT orders, and container quantities?
