Identity gate
Chemical name, CAS when known, rutile or anatase, surface treatment, and whether a chloride or sulfate route is requested. Two titanium dioxide manufacturers can share a family name and still quote different substances.
Pre-inquiry checklist
titanium dioxide manufacturers sourcing checklist
Resolve specification, document and approval questions before inquiry for titanium dioxide manufacturers. This page is a buyer checklist, not a sustainability statement, carbon claim or ESG score. Nothing here asserts stock, mill capability or a completed plant audit.
- Identity and crystal form written
- Coatings measurements listed or marked open
- Documents requested for the exact code
- Approvers named outside the quotation
Checklist items that must be closed or marked open
Closing an item means the buyer wrote a value or explicitly left it for the mill. Marking it open is acceptable. Guessing a typical oil absorption or brightness to look complete is not.
Measurement gate
Resin system, solids, viscosity, color, cure schedule and coverage questions. Assay, particle size, moisture and oil absorption stay as requested values or as open confirmation fields.
Document gate
SDS, TDS, CoA format, TSCA or REACH text, and transport classification for the destination. A file from a related grade is a miss, not a pass.
Approval gate
Name the laboratory, EHS and commercial reviewers who will accept or reject a sample. Those names sit outside the quotation itself.
Selection trade-off we keep visible: treated rutile often costs more and can reduce photocatalytic chalking in exterior films, while untreated or anatase options may be requested for indoor or specialty paths. We do not declare a winner. We only keep both options on separate lines if the buyer still wants both quoted.
Questions to close before writing titanium dioxide manufacturers
If any answer is still “unknown,” leave it labeled unknown on the RFQ. Do not borrow a competitor brochure number to fill the blank.
Write grade, concentration and configuration. If the historic lot used a silica-alumina treatment, say so. If the buyer will accept either treatment, say that as two lines rather than one vague pigment name.
The mill cannot see the host formula unless you state resin system and solids, plus viscosity, color, cure schedule and coverage questions that remain with formulation.
List current SDS, TDS, CoA columns, bag or FIBC drawing, moisture, UN number if assigned, and who signs sample acceptance. This checklist does not replace those reviewers.
Return to inquiry grades or supplier fields after the gates are written.
Request factory quotes after the checklist is written
Submit the closed gates and the items still marked unknown in one packet. Do not fill oil absorption from a brochure to make the form look complete. Preference among titanium dioxide manufacturers remains a buyer hint.
