Electronic component supplier vetting should establish who the business is, where parts come from, how quality is controlled and what happens when evidence or product does not meet requirements. The depth of review should match the risk of the part, source and application.
Verify the legal business and operating location
Confirm registered company name, address, ownership, tax or registration details, website domain, telephone and bank beneficiary. Check that quotations, invoices and payment instructions use consistent identities.
Verify the physical location and the functions performed there. A sales office, warehouse, test laboratory and manufacturing site provide different capabilities. Investigate recent domain registration, copied certifications, mismatched addresses or pressure to pay an unrelated entity.
Establish the supply path
Ask whether the supplier is the manufacturer, an authorized distributor, an independent distributor or a broker. Verify authorization with the manufacturer or its published channel where that status is claimed.
For independent supply, require a documented chain of custody or disclose the limits of traceability. Record the original manufacturer, complete ordering code, quantity, date code, lot code, packaging and source category on the purchase record.
Review the quality management system
Request the quality certificate and verify its issuing body, scope, sites and expiry. A certificate supports process control but does not prove that a particular shipment is genuine or conforming.
Review procedures for supplier approval, receiving inspection, nonconforming material, calibration, training, document control, ESD handling, storage, change notification and corrective action. For higher-risk procurement, audit the facility or use an independent auditor.
Match controls to counterfeit risk
SAE's AS6081 standard page describes requirements for avoidance, detection, mitigation and disposition of fraudulent or counterfeit electronic parts by distributors. Apply the standards and customer requirements relevant to your sector and contract.
Define inspection and test requirements before ordering. These may include packaging review, label and marking inspection, dimensional checks, microscopy, X-ray, XRF, decapsulation, solderability or electrical test. No single test proves authenticity for every component; use a risk-based sequence and qualified laboratories.
Check handling and storage
Confirm ESD controls, moisture-sensitive-device handling, temperature or humidity limits, baking records, dry packing and shelf-life control. Inspect whether returned, rejected and suspect product is physically segregated.
For reels, trays, tubes and dry packs, require packaging that protects parts and preserves traceability. Repackaging should be disclosed and controlled.
Evaluate commercial and logistics capability
Review normal lead times, allocation handling, minimum order quantities, cancellation terms, shipment methods, incoterms and insurance. Ask how shortages, split shipments and export restrictions are communicated.
Compare pricing with market conditions. An unusually low price or immediate availability of a scarce part is a risk signal that needs evidence, not an automatic rejection or acceptance.
Define documentation in the purchase order
State the complete part number, manufacturer, quantity, packaging, allowed date or lot codes, traceability, certificates, inspection, change notification and approval requirements. Define whether substitutions, mixed lots or repackaged material are prohibited or require written approval.
Include rights for rejection, failure analysis and corrective action. Agree on how suspect parts will be contained and reported.
Run a controlled first order
Start with a limited purchase that exercises quotation, order acknowledgment, documentation, shipping and receiving inspection. Record discrepancies and response quality before expanding business.
Supplier approval is not permanent. Monitor on-time delivery, escapes, documentation errors, complaints, corrective-action response and business changes. Reassess when risk or performance changes.
