Identity and assay
Collect chemical name, CAS number if known, requested concentration, assay method, and active content. If the buyer only knows a trade family, the RFQ marks identity as open rather than guessing a CAS number.
Document-first workflow
Diesel fuel biocide quotes aligned on files, not on family names
This page explains how Biocide Sourcing normalizes supplier answers for diesel fuel biocide. The work is specification capture, evidence requests, and delivered-scope comparison. It is not manufacturing, warehousing, or a claim that any plant is already audited.
A usable quotation names the proposed code, active content, ionic type, package, incoterm, freight inclusions, and the SDS, TDS, and CoA that belong to that code. If a plant offers a substitute concentration or carrier, the substitute is written on a second line so the original request stays visible.
Laboratory, EHS, and formulation decisions remain with qualified parties at the buyer. Handling and transport follow the lot SDS, UN number, carrier instructions, and destination rules. We do not issue mixing directions or a performance guarantee.
Quote ledger fields
Fields we ask every proposed diesel fuel biocide line to answer
The cards below are intake fields, not plant capabilities. Empty or conditional answers stay on the comparison sheet. No factory history, capacity figure, or borrowed certificate is inserted to fill a gap.
Physical confirmation window
When the process needs them, list pH, density, viscosity, flash point, moisture, and solids content as confirmation items. Typical brochure ranges do not replace lot values.
Packaging and movement
Record preferred pails, drums, IBCs or bulk, net content, pallet limits, labeling language, storage range, and any site restriction that can change the UN number or carrier choice.
Evidence pack
Ask for current SDS, TDS, and CoA format for the quoted code. TSCA, REACH, GMP, ISO, DOT, or IMDG questions are sent as verification requests. Answers attach to the product, not to this website.
Commercial scope
Align currency, quantity unit, package contents, incoterm, freight, duties, sample cost, and exclusions before any unit-price ranking. An optional budget with currency and per-unit or whole-order basis can sit beside the brief. High-end, mid-range, budget, or undecided is a preference, not a rating.
SDS / TDS / CoA questions
Document questions that prevent borrowed-file comparisons
Does the SDS match the quoted concentration?
Ask the supplier to confirm product code, concentration, and revision date. A family SDS or another manufacturer file is not evidence for the offered lot.
Which assay appears on the CoA?
Request the reported active content, method, and any secondary limits the buyer named. A blank CoA template is useful only if the supplier states which fields will be completed.
What does the TDS actually constrain?
Use the TDS to list properties the buyer wants confirmed, such as ionic type, density, or pH. Marketing paragraphs on the same sheet are not purchase specifications.
When should transport data be requested?
Ask for classification, UN number, packing group, and flash point for the exact concentration and pack. Final movement still follows the SDS, carrier, and destination rules.
