Salt Supplier Onboarding and Approved Vendor List Process

Approving a supplier only because the quotation is attractive can create quality or documentation surprises on the first shipment. Supplier onboarding should connect technical capability, commercial terms, documents and first-order performance.

Start with prequalification

Product range, production/packing capability, required grain sizes, packaging options and export experience are practical first-stage filters.

Standardize the document pack

Company information, product specification, sample COA, quality documentation, label/packaging examples and required commercial documents should be requested through one checklist.

A sample and a trial shipment are different stages

A laboratory or desk sample does not prove full-scale packing and logistics performance. The first commercial order can be treated as a separate qualification step.

Use risk-based audit decisions

A physical factory audit may not be required for every supplier. Product risk, annual volume, private-label needs and performance history can guide the decision.

Define the approved-vendor scope

Approval can be tied to a product, facility, packaging format or destination. The procedure should state which changes trigger reassessment.
