Case Study: Serpentine Belt Supply for a tour operator in the Middle East

Serpentine Belt for A tour operator in the Middle East

A tour operator came to us with a serpentine belt programme for the Middle East. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • A specification nobody had written down
  • Packing that arrived crushed at the port
  • Documentation that arrived after the container shipped

ClientA tour operator
Marketthe Middle East
Volume50,000 pieces across 3 specifications
Base materialCast Iron
Sampling rounds4
Delivery window4 weeks from PO to ex-factory
ComplianceIATF 16949

How it was resolved

  1. The specification was rebuilt around Cast Iron and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Result

  • 50,000 pieces delivered inside the 4-week window.
  • Unit cost held within 3.0% of the original quotation.
  • Inspection-related rejection stayed under 2.0%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Approve a pre-production sample made from the actual bulk material. Substitute material behaves differently in service.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
