Agricultural Silicone Agro Adjuvant, CAS 67674-67-3, Polyether-Modified Trisiloxane Liquid
Buyer-facing sourcing profile for an agricultural silicone adjuvant supplied as a transparent liquid, described as a low-molecular-weight nonionic polyether-modified trisiloxane for wetting, spreading, and penetration applications in agrochemical formulations. Buyers should confirm CAS alignment, model grade, surface tension, viscosity, cloud point, pH tolerance, impurity profile, packaging format, export documents, and dangerous goods classification before RFQ or sample approval.

Package and route
Packing notes
Packing options referenced: 25 kg, 50 kg, 200 kg, and 1000 kg packages
Transport package referenced: drum / IBC
Confirm whether drums are HDPE, iron, or fluorinated plastic and whether inner liners are available
Request net weight, gross weight, pallet configuration, container loading quantity, and shelf-life statement
Confirm sample size, sample packaging, and whether sample COA matches commercial batch specifications
Ask whether export packing is suitable for sea freight and whether air shipment is available subject to DG classification
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
Procurement of silicone-based agro adjuvant for formulation evaluation
Sourcing of low-surface-tension nonionic silicone surfactant for agricultural input portfolios
Distributor qualification for agricultural wetting and spreading auxiliaries
Comparison of trisiloxane adjuvant grades by viscosity, cloud point, pH tolerance, and foaming profile
Sample screening prior to local registration or formulation approval
How we compare
Sourcing options
Request sample with matching COA before commercial PO
Qualify at least two grades if cloud point or pH tolerance is critical
Compare drum versus IBC pricing for import economics
Ask supplier to quote FOB China port, CIF destination port, and DAP options where available
Use third-party pre-shipment inspection for first commercial order
Request bilingual labels and destination-compliant SDS before shipment
Human review
Compliance notes
Request COA, SDS, TDS, product specification sheet, composition disclosure suitable for import review, and batch traceability documents
Verify whether CAS 67674-67-3 correctly represents the supplied grade or whether the product is a mixture requiring component-level disclosure
Confirm dangerous goods status under IMDG, IATA, and local import rules before booking shipment
Check agrochemical adjuvant registration requirements in the destination country; supplier claims do not replace buyer-side regulatory review
Confirm REACH, K-REACH, UK REACH, TSCA, DSL/NDSL, AICS/AIIC, IECSC, or other inventory status as applicable to destination market
Request impurity information relevant to silicone surfactants, including volatile siloxanes, residual solvents, unreacted intermediates, water content, and heavy metals if required by buyer specification
Confirm labeling requirements, GHS classification, storage temperature statement, shelf life, and transport name with supplier documentation
Do not treat supplier performance claims as regulatory or efficacy guarantees; require buyer-side formulation and compliance validation
