Package and route
Packing notes
Listed packing options include 1 L, 5 L, 25 kg, 200 kg, or IBC tank; confirm exact drum/IBC material, net weight, palletization, and seal type
Bulk IBC listing shows approximate package gross weight of 1057 kg; confirm net content per IBC and container loading quantity
Request export-ready labels matching product identity, batch number, net weight, origin, and SDS transport information
Confirm shelf-life statement, manufacturing date, retest date, and storage statement as they appear on COA/TDS; source lists 36 months
Confirm sample availability, sample size, courier documentation, and whether sample COA/SDS can be issued before shipment
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
Specification comparison for silicone spray adjuvant sourcing
Supplier pre-qualification before agrochemical adjuvant RFQ
Sample screening for wetting, spreading, and penetration performance in approved formulations
Commercial procurement of polyether modified trisiloxane surfactant in drums or IBCs
Document review for import, transport, and agrochemical auxiliary compliance
How we compare
Sourcing options
Request sample with COA/SDS/TDS before bulk order
Start with 25 kg drum for pilot formulation evaluation if supplier supports small commercial quantity
Use 200 kg drum or IBC tank for regular production procurement after specification approval
Ask for FOB China port quotation and separate freight estimate for CIF/CFR comparison
Consider third-party pre-shipment inspection for identity, appearance, packing, labeling, and COA consistency
Human review
Compliance notes
Request current SDS in GHS format and verify classification, pictograms, UN number status if any, marine pollutant status, and transport name before booking freight
Do not rely on marketplace category alone; confirm whether the item is regulated as dangerous goods for sea, air, road, or courier shipment
Confirm export documentation availability: COA, SDS, TDS, commercial invoice, packing list, certificate of origin if needed, and batch traceability statement
Check whether CAS 67674-67-3 and the supplier’s polymer description are accepted under the buyer’s local chemical inventory and agrochemical-adjuvant rules
For agricultural use, buyer should verify local registration, formulation-adjuvant approval, tank-mix label compatibility, and permitted end-use requirements in the destination market
Confirm impurity and residual profile relevant to silicone surfactants, including residual solvents, cyclic siloxanes if applicable, water content, acid value/pH, heavy metals if required, and VOC content where relevant
Supplier claims such as non-toxic or environment friendly should be treated as marketing claims unless supported by SDS, toxicology summary, and jurisdiction-specific compliance documentation
No regulatory approval, pesticide efficacy, crop safety, or import clearance should be assumed from the source listing
