Document guide
Acid corrosion inhibitor manufacturer files to request before inquiry
This page is a specification and evidence checklist for an acid corrosion inhibitor manufacturer RFQ. It is not an ESG statement, carbon program or plant certification. Files must match the quoted acid type, concentration and inhibitor chemistry.
Document pack the manufacturer should attach to the quote
Request current revisions. A related-grade file is a gap, not a pass. Safety data sheet, technical data sheet and certificate of analysis are the core three; TSCA, REACH, GMP or ISO pages are added only when the destination or use needs them.
- Safety data sheet. Composition range, flash point, pH, UN number and storage statements for the quoted concentrate. Handling and transport follow this file, not this website.
- Technical data sheet. Assay or active content, density, viscosity, recommended acid types if the factory publishes them, and typical versus specification columns clearly labeled.
- Certificate of analysis format. Methods for assay, moisture, residual solvent or trace metals that the incoming lab will actually run.
- Transport note. DOT or IMDG class proposed for the package size going to the US site. Carriers may still refuse a class that looks correct on paper.
- Sample protocol. What the trial quantity is meant to confirm: coupon appearance, pickle rate change, residue or another buyer-owned criterion.
Trade-offs that documents will not hide
Amine-type acid inhibitors can leave odor and residual film; some film-forming packages slow metal loss but also slow scale removal. Higher active content can raise transport class. These are selection factors. Neither route is declared superior here, and neither is a performance promise from this desk.
Approval questions before the inquiry leaves the buyer
- Which acid, concentration and temperature will the inhibitor see, and who inside the company owns that number?
- Is nitrite, heavy-metal or specific amine chemistry restricted by the site or by a customer spec?
- Will quality accept a mill CoA, or is a third-party assay required for the first lot?
- Are drums allowed at the dock, or must the quote use IBCs with a different UN package instruction?
- Which open fields (particle size, molecular weight, solids content) are unused and should stay off the RFQ?
Unresolved answers should remain visible on the comparison sheet. Use the procurement brief as the working template.
Request documents with the acid corrosion inhibitor manufacturer quote
State acid type, bath concentration, temperature window, quantity, package and the US receiving site. Factories are then asked for SDS, TDS and CoA that match that quoted concentrate.
