Evidence boundary
Keep requested values and quoted answers on one visible table
A trade name is not an assay. Before unit price is discussed, the request should show which fields the buyer specified and which fields remain for the proposed lot. Safety data sheet, technical data sheet, and certificate of analysis files must belong to the exact quoted product, not a related grade.
| Field | Why we ask | Status if unconfirmed |
|---|---|---|
| Chemical name / CAS number | Known identity keeps quotes on the same molecule instead of a related family name. | Open until the quoted code is matched |
| Active content / assay | Target or range lets a plant report the lot method and result on the same line. | Open until matched |
| Ionic type / pH / density | Limits that are process-critical must be answered as quoted values, not brochure typicals. | Open until matched |
| Packaging and UN number | Preferred pack and site limits change transport class and receiving cost. | Open until matched |
| SDS / TDS / CoA | Current exact-product files belong to the quoted code, not a related grade. | Open until matched |
| Check family | Count on the brief | Status if unconfirmed |
|---|---|---|
| Identity checks | 5 items: name, CAS if known, grade, assay, and ionic type | Held open until the quoted code answers each cell |
| Document questions | 19 notes covering SDS, TDS, CoA fields, revision dates, and related verification | Files stay unmatched until they name the quoted product |
| Packaging and destination | 13 checks including pack type, net fill, labels, and US receiving limits | Freight is not ranked until pack and site limits are answered |
| Specification cells | 13 values a factory still has to confirm | Blank cells stay visible instead of typical brochure figures |
| Comparison notes | 19 notes kept visible when a substitute active, concentration, or pack appears | Alternates stay on a second line until the buyer accepts them |
Flash point, viscosity, moisture, solids content, and particle size stay on the same sheet when the process needs them. A blank cell is more useful than an assumed typical value. REACH, TSCA, GMP, or ISO statements are verification questions for the proposed supplier and product, not credentials of this website.
Use-case pairs
Translate the operating context into purchase fields, not performance claims
The same family name can sit in diesel storage, metalworking fluids, process water, or in-can preservation. Each row below lists what the RFQ should capture. None of these scenes implies that a sourced grade is suitable, registered, or already approved at the receiving site.
| Field / context | Why we ask | Status if unconfirmed |
|---|---|---|
| Diesel tank programs | Record whether the inquiry is for diesel biocide, treat rate questions, water-bottom handling limits, and whether the receiving site can accept drums or IBCs. Concentration, carrier, flash point, packaging, UN number, and the SDS for the exact concentration stay visible before freight is compared. | Quote line stays open until pack and concentration are named |
| Metalworking fluids | State the fluid type, desired ionic type, compatibility questions, and whether a trial lot or recurring forecast is intended. Active content, pH window, density, pack size, and CoA format are listed as confirmation items, not as promised use outcomes. | Assay and ionic type remain unmatched until the lot is quoted |
| Process water circuits | Describe the circuit, any residual limits, and who will review identity and assay after a sample arrives. Grade, assay method, storage range, and transport classification remain supplier answers bound to the quoted lot. | Identity and transport class stay blank until the plant answers |
| Coatings preservation | Capture in-can versus dry-film intent, color or odor limits, and whether a substitute active is allowed. If a supplier offers an alternative active or pack, place it on a separate line and wait for buyer approval. | Substitute actives stay on a second line until approved |
RFQ questions
Questions that keep biocide quotations comparable
Use this rail to keep identity, assay, documents, and sample purpose on the same brief. Answers belong to the quoted code. This desk does not fill empty cells with typical brochure values.
Requirement form
Send the sample purpose with the brief
Samples and files
Ask for sample purpose and exact-product files in the same note
State what a sample should confirm, who reviews it, and which SDS, TDS, and CoA files must accompany the quotation. Handling, storage, and transport follow the lot SDS, carrier rules, and applicable regulations. No savings percentage or lowest-price outcome is published. Review the inquiry configurations, the quote workflow, or the procurement brief before sending the first request.
