Polycarboxylate Superplasticizer Mother Liquor for Concrete Admixture Sourcing
Buyer-facing sourcing profile for a polycarboxylate-based water-reducing admixture mother liquor offered for concrete applications. Key checks should focus on exact product identity, grade, solid content options, chloride/alkali/sulfate limits, batch COA availability, packing format, export documents, and whether the material is supplied as non-DG liquid cargo under the seller’s current SDS and transport classification.

Packing notes
Standard liquid packing stated: 1 metric ton plastic barrel / IBC-type package
Alternative packing stated: 200 kg plastic drum
Tank storage or bulk shipment may be possible; confirm minimum order quantity and loading method
Request net weight, gross weight, palletization, container loading quantity, and package dimensions
Confirm packaging compatibility with destination handling requirements and whether UN-approved packaging is required under the current transport classification
Ask supplier to confirm shelf life and retest policy; source text references one-year storage with retesting after expiry
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.

How we compare
Sourcing options
Request sample for lab compatibility testing with local cement, sand, aggregate, and admixture systems
Source by solid content grade, such as 40%, 50%, or 60% liquid
Source in 200 kg drums for trial lots or 1 ton IBCs for commercial shipments
Request customized performance profile for water reduction, slump retention, or compatibility requirements
Ask for batch-reserved production with pre-shipment COA approval
Consider supplier audit or third-party inspection for recurring import programs
Human review
Compliance notes
Request latest SDS in GHS format, COA, TDS, packing list, commercial invoice, certificate of origin, and export declaration support
Confirm whether the product is classified as dangerous goods for sea, air, road, or rail transport under the supplier’s current SDS
Source text states the product is not flammable and not explosive; buyer should verify against SDS and carrier acceptance requirements
Confirm chemical inventory status or notification obligations in destination market where applicable; do not rely on marketplace text as regulatory confirmation
Because no CAS is listed, request polymer identity, monomer/residual impurity disclosure where legally shareable, and any confidential composition handling process
Verify chloride, alkali, sulfate, and formaldehyde limits against the buyer’s concrete admixture standard and local construction specifications
Confirm whether the offered product complies with destination standards such as ASTM, EN, GB, or project-specific concrete admixture requirements if needed
Check export documentation readiness before order placement, especially for mixed polymer liquid cargo and customs classification under HS 38244010
