Authorized distribution
Authorized channels provide a direct manufacturer relationship and are normally the first choice for current-production material when stock and commercial terms fit.
Independent distribution
Independent channels can locate shortage, excess, allocated or obsolete material, but require stronger supplier qualification and product verification.
Decide by risk
The correct inspection scope depends on source, part value, application sensitivity and available traceability.
- Classify the source before quoting
- Define evidence required before payment
- Match testing depth to the application
- Document any approved exception
