Company proof
Ask for company profile, business registration details, address, contact information and equipment photos for supplier review.
Supplier verification
Give buyers a clear due-diligence path without overstating proof.
This page separates what can be requested, what must be confirmed per project and what should not be claimed without original documents.
Verification rule
Use original files, project-specific test records and contract terms. Do not treat website copy as certification.
Technical proof
Request configuration sheet, chamber drawing or layout, vacuum system path, control cabinet scope and option list before final quotation.
Production proof
For confirmed orders, track production photos, component readiness, inspection points and agreed progress updates.
FAT proof
Agree the FAT checklist before shipment: no-load heating, vacuum check, safety check, control operation and photo/video records.
Export proof
Commercial invoice, packing list, shipping marks, packing photos, manual and freight documents should match the final contract scope.
After-sales proof
Clarify spare parts, remote support, commissioning responsibility, warranty start point and exclusions before deposit.
Do not overclaim
Items that must stay project-specific.
CE, special market certificates, test values, delivery dates, installation scope and warranty exclusions should not be promised generically. They must be confirmed in the quotation, PI or contract.
Buyer due diligence
Request the documents your procurement team actually needs.
Tell sales your destination country, furnace type, application and document checklist.
