Identity lock
Chemical name, CAS number where known, and whether the buyer will accept an alternative salt or solvent system. Substitutions move to a separate line for approval.
Manufacturer matching
Corrosion inhibitor manufacturers quoted on one field set
This matching desk normalizes what each factory must answer. It does not rank plants, claim capacity or treat a returned SDS as this site's credential.
| Quote field | Buyer records | Factory confirms |
|---|---|---|
| Active content | Requested percent or range | Assay method and lot window |
| Ionic type | Anionic, cationic, mixed or unknown | Actual ionicity of the quoted blend |
| pH and density | Process window if known | Measured values on the TDS |
| Packaging | Drum, IBC, tote and net fill | Package material and labeling |
Requirement cards used before a manufacturer is contacted
Use these cards to stop apples-to-oranges replies. A missing field stays visible; it is not filled with a marketing default. Trace metals, moisture and particle size are requested only when the application actually needs them.
Assay lock
Purity or concentration, active content, solids content and any viscosity limit. Molecular weight is recorded only for polymer-type inhibitors.
Document lock
SDS, TDS and certificate of analysis format for the quoted product. ISO 9001, GMP, REACH or TSCA evidence is a supplier question, not a site badge.
Lane lock
Quantity unit, requested timing, US destination, UN number if the factory already assigned one, and whether a sample precedes the bulk lot.
SDS, TDS and CoA questions for manufacturer replies
Exact-product SDS, TDS and CoA describe the quoted inhibitor grade. They do not authorize Corrosion Inhibitor Sourcing to run a plant or to instruct hazardous mixing. Storage and carriage still follow that SDS, the carrier and US destination rules.
- Can one CoA cover the next lot?
- A CoA is lot-specific. Ask whether the next production batch will reissue assay, pH, density and residual solvent on the same method.
- If TDS lists a typical pH, is that the specification?
- Typical values are not purchase limits unless the factory writes a min/max. Record the gap instead of treating the typical column as a guarantee.
- What if flash point is blank?
- Leave the field open. Do not copy a flash point from a different solvent system. Transport class can change with that number.
- Should nitrite-free and film-forming packages be compared as one SKU?
- No. Chemistry route, residual nitrite concern and metal compatibility are different buyer decisions. Keep them as parallel quotations.

Send assay window, ionic type, drum or IBC fill, quantity unit and the US receiving site. Matching then asks plants for the same fields. The form does not publish a lowest price or a promised lead time.
