Safety data sheet
Identity, hazards, storage range, flash point and transport classification for the quoted concentration. Final handling follows this file, applicable rules and the carrier. This page does not give mixing instructions.
Document guide
Catalyst Manufacturers Document Checklist Before Inquiry
Use this guide to decide which files catalyst manufacturers must attach to a quote. It is a buyer checklist, not a sustainability statement and not a certificate held by Catalyst Supplier Sourcing.
File set
What each document is for on a catalyst RFQ
Technical data sheet
Assay, active content, ionic type, particle size, moisture, density, pH and other limits. If a factory answers with a different grade, keep that answer on a separate comparison line.
Certificate of analysis
Lot-level measurements against the agreed fields. Ask for the format before production. A CoA from another manufacturer or a related grade is not evidence for the quoted item.
Status questions
TSCA for US supply, REACH where relevant, GMP for applicable pharmaceutical scopes, supplier ISO 9001 evidence, and DOT or IMDG class. These remain supplier statements until the buyer reviews them.
Review limits
Where document review stops
No. Concentration, form, residual solvents and transport class can change between neighboring grades. Ask for the file that names the quoted product.
No. Those status questions are sent to the proposed supplier and bound to the exact product. This independent desk does not borrow competitor credentials.
Keep the blank visible. Do not infer a class from a product family. Carrier acceptance and labeling follow the completed SDS and applicable regulations.
A second trade-off sits between waiting for a complete document set and placing a trial order on partial files. Waiting can delay a reload window; proceeding on a related-grade SDS or an unsigned CoA template can leave EHS and quality without a usable acceptance basis. Record whichever path the buyer chooses as a decision, not as a claim that the missing file has been waived by this service.
