Before matching
Documents to check
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
Standard packing listed as 25 kg plastic bag; confirm inner liner, moisture barrier, palletization, and container loading quantity
Request photos of bag markings, batch number format, production date, net weight, and country of origin marking
Confirm whether export pallets are fumigated or non-wood, and whether pallet wrapping is moisture-protected for sea freight
For Saudi Arabia/GCC shipments, confirm Arabic/English label requirements with importer before dispatch
Ask whether sample packs are available from the same production grade and whether sample COA matches bulk shipment specifications
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
Performance additive for cement-based tile adhesive grades
Polymer modifier for dry-mix mortar systems requiring adhesion and flexibility
Additive candidate for EIFS bonding and base coat mortar
Polymer powder candidate for self-leveling cement and repair mortar products
Flexible putty and skim coat formulation supply chain evaluation
Construction chemical distributor catalog item for GCC building material producers
How we compare
Sourcing options
Request 1–5 kg sample with matching COA before tonnage purchase
Start with 1 ton MOQ trial order for formulation validation and local compliance review
Compare several RDP grades by MFFT, Tg, ash content, solid content, and application focus
Request FOB China and CIF/CFR Saudi port quotations with 25 kg bag palletized packing
Use third-party pre-shipment inspection for packaging, labeling, net weight, and batch COA matching
Ask supplier for alternative grades if buyer requires higher bonding strength, lower MFFT, improved water resistance, or specific tile adhesive performance
Human review
Compliance notes
Request current COA, SDS/MSDS, TDS, product specification sheet, packing list template, commercial invoice template, certificate of origin, and HS code confirmation before RFQ approval
Confirm CAS 24937-78-8, polymer identity, and absence/presence of restricted additives according to buyer’s destination requirements
Clarify DG status for sea and air export based on supplier SDS; do not rely only on marketplace description
For Saudi Arabia import, buyer should confirm SASO/SABER, customs classification, labeling, and construction chemical documentation requirements with local broker or compliance consultant
Check whether product contains residual monomers, plasticizers, anti-caking agents, protective colloids, or other additives that may affect local compliance or formulation performance
No regulatory approval, customs clearance, or end-use compliance should be assumed without review of destination-specific documents

Questions to confirm
Can you provide COA, SDS, TDS, and full specification for the exact RDP grade offered, not only the marketplace listing?
Please confirm CAS number, polymer base, ethylene content range if available, ash content, volatile content, residual monomer limits, and additive package disclosure level.
What are the tested values for solid content, pH, bulk density, particle size, MFFT, Tg, viscosity effect, and redispersion performance for the latest batch?
Is this grade specifically optimized for tile adhesive, EIFS, self-leveling mortar, or flexible putty? Please provide recommended performance positioning without formulation instructions.
What impurity or quality limits are controlled, including moisture, ash, insoluble matter, residual vinyl acetate monomer, odor, and caking?
Can you confirm the product is not a concrete retarder if the title is mismatched, and clarify whether it is RDP powder for dry-mix mortar?
What is the minimum order quantity, lead time, monthly capacity, sample availability, and sample-to-bulk batch traceability?
What packaging options are available: 25 kg bags, jumbo bags, palletized export packing, container loading quantity, and moisture protection?
