File checklist
Independent sourcing partner
Crop Protection Sourcing is an independent sourcing partner for US business buyers that need crop protection for formulation, packing or distribution programs. We collect the chemical name, CAS number when known, grade, assay, formulation, quantity, packaging and destination, then request factory wholesale quotations on that same brief.
This desk does not hold inventory, does not apply products, and does not treat a product-family page as proof that a named plant can supply the exact concentration. Handling, storage and transport stay bound to the exact SDS, UN number and carrier rules that the proposed supplier later confirms.
Evidence boundary
Use the table as a buyer checklist. Public chemical-family references can frame questions; they do not replace confirmation for the exact quoted material, moisture limit, particle size or active content.
| Field | Buyer records | Supplier must answer | Desk limit |
|---|---|---|---|
| Identity | Chemical name, CAS number if known | Exact grade and alternative if proposed | No borrowed identity from a similar family |
| Assay / purity | Requested concentration or open range | Assay method and certificate of analysis format | No performance claim from a typical assay |
| Formulation | EC, SC, WG, SL or technical concentrate | Carrier, stabilizer and pack compatibility | No mixing or use instructions |
| Documents | SDS, TDS, CoA, sample need | Current files for the quoted lot format | No site-owned REACH, TSCA or GMP badge |
| Transport | US destination and site constraint | UN number, packing group, flash point if relevant | Final carrier decision stays with qualified parties |
Use pairs
A formulator comparing crop protection technical concentrate needs viscosity, density, pH, solids content and residual solvent limits written on the RFQ so two plants do not quote different carriers under the same name.
A packer filling jerrycans or water-soluble bags must state pack size, liner material and labeling language. Those choices change palletization and hazardous-material paperwork even when the assay looks identical.
A distributor staging a US warehouse should record crop or use, market registration questions and whether the brief is a sample, trial lot or firm order. Registration status is a supplier statement to verify, not a desk certificate.
A project buyer using a crop-protection chemistry in a non-grower process still needs the same SDS, flash point and storage range. Application novelty does not relax document checks.
RFQ questions
Write the chemical name, CAS number if known, active ingredient, assay and formulation. If any field is still open, mark it as supplier-to-confirm instead of implying a default technical grade.
Ask for the stated active content, the assay method, and whether the certificate of analysis will report that method for the shipped lot. A related-grade SDS is not evidence for the quoted concentration.
List the files you need, pack size, pallet pattern, US destination and requested delivery window. Keep blank answers visible. Do not compare unit price until currency, quantity, Incoterm and freight exclusions line up.
Those are different purchase bases. A technical concentrate and a registered end-use formulation can share an active ingredient while differing in assay, adjuvants, labeling and destination paperwork. Keep them on separate quote lines.
Define what a sample is meant to confirm: identity, appearance, assay, viscosity, particle profile, packaging or another buyer-approved criterion. A sample does not approve a production lot and does not authorize field use. After you submit, we review the product, quantity, destination and sourcing requirements, then request factory quotes.
