Package and route
Packing notes
Quoted source packaging includes 200 kg drum and 1000 kg IBC options
Smaller packs are also listed: 25 kg, 1 kg, 500 ml, and 250 ml; confirm commercial availability for export orders
MOQ shown by source: 200 kg; sample pricing was displayed separately on the source page
Request UN-rated or export-suitable packaging confirmation if classified as dangerous goods in the destination lane
Ask for palletization details, net/gross weight, drum dimensions, and shelf-life labeling format
Confirm whether packaging is original manufacturer sealed and whether tamper-evident export labels 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
Component screening for agrochemical adjuvant formulations
Sourcing evaluation for nonionic organosilicone surfactant supply
Replacement or dual-source qualification for polyether modified trisiloxane adjuvants
Export procurement where CAS, SDS, COA, and registration-support documents are required
Technical comparison of spray-spreader adjuvant grades by viscosity, surface tension, and water dispersibility
How we compare
Sourcing options
Request a document-first quotation with SDS, TDS, COA template, certification copies, packaging photo, and DG statement before price negotiation
Order a sealed sample with batch COA for independent lab confirmation of identity, viscosity, and surface tension
Compare 200 kg drum versus 1000 kg IBC pricing, lead time, and freight classification
Ask for current export references or shipment experience to the intended destination region
Use third-party inspection for batch sampling, labeling, packaging integrity, and document matching before shipment
Qualify at least two equivalent grades if the source page has inconsistent TIS-304/TIS-327 references
Human review
Compliance notes
This is an agrochemical adjuvant candidate; buyers should verify whether it is regulated as an inert ingredient, co-formulant, adjuvant, surfactant, or pesticide-related component in the destination market
CAS No. 134180-76-0 and product grade should be checked against SDS, TDS, COA, REACH documentation, and any local agrochemical registration requirements
The source references REACH, ISO9001, and OMRI; request current dated certificates, registration holder details, and coverage for the exact product grade
Request SDS in the destination language/format, including GHS classification, transport section, exposure controls, and ecological information
Flash point is listed as 117°C; DG/export status should be confirmed using the latest SDS and shipping lane requirements
Do not rely on marketplace claims for regulatory acceptance; obtain importer-side review before purchase
Ask whether the product contains residual solvents, cyclic siloxanes, low molecular weight siloxanes, EO/PO residues, or other impurities relevant to destination compliance
Confirm whether the supplier can provide non-GMO, OMRI, REACH, RoHS, TSCA, or other declarations only where applicable and documented
