Purchasing potent industrial chemicals requires rigorous supplier verification to ensure product quality, safety, and regulatory compliance. This comprehensive checklist helps buyers properly vet chemical suppliers and verify documentation authenticity.

Company Verification Checklist

✅ Verify business registration in claimed jurisdiction
✅ Confirm physical address through independent sources
✅ Check for manufacturing facility details and certifications
✅ Verify environmental permits and regulatory compliance
✅ Confirm membership in industry associations

✅ Export/import compliance documentation
✅ Transportation safety documentation

MSDS/SDS Verification Steps

Legitimate safety data sheets should:

• Be specific to the manufacturer, not generic templates
• List actual manufacturer contact information
• Provide specific composition information (within proprietary limits)
• Include manufacturer-specific hazard classifications
• Reference batch-specific testing where applicable
• Be consistent with known hazards of similar chemicals

Certificate of Analysis (COA) Verification

Authentic COAs include:

• Independent laboratory letterhead and contact information
• Specific testing methods and equipment used
• Batch numbers matching product labeling
• Testing dates relevant to current inventory
• Clear specification of what parameters were tested
• Actual numerical results with measurement uncertainties

Supplier Interaction Red Flags

🚩 Resistance to providing documentation
🚩 Inconsistent information across communications
