OEM / OES / IAM — Three tiers, one source.
Stocked in parallel across all three specification levels. Component tier confirmed at enquiry stage — no substitution without documented consent.
Confirm your tier before the order.
OEM
OES
IAM
Produced by the same Tier-1 supplier that manufactures for the OEM line, under identical tooling. Specification-equivalent; sourced outside the OEM distribution channel.
Third-party manufactured to functional OES standards. Any deviation from OEM specification is documented, declared at enquiry, and confirmed before order placement.
Factory-matched parts produced to the original manufacturer's exact drawing and material specification. Full traceability and certification supplied with each shipment.
IAM deviations documented before purchase.
Every IAM component is benchmarked against OES functional standards. Where material grade or dimensional tolerance differs from OEM drawing, the deviation is recorded in the enquiry response — never carried silently into a purchase order.

Cross-reference data supplied at enquiry.
Submit your component specification — part number, vehicle application, or fitment parameter — and receive a confirmed tier classification and cross-reference before any purchase obligation.
