Case Study: Ball Joint Supply for a tour operator in Eastern Europe

Ball Joint for A tour operator in Eastern Europe

A tour operator came to us with a ball joint programme for Eastern Europe. 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 supplier who changed material without saying so
  • Packing that arrived crushed at the port
  • Documentation that arrived after the container shipped

What was specified

ClientA tour operator
MarketEastern Europe
Volume10,000 pieces across 6 specifications
Base materialEPDM Rubber
Sampling rounds3
Delivery window4 weeks from PO to ex-factory
ComplianceISO/TS 16949

How it was resolved

  1. The specification was rebuilt around EPDM Rubber 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

  • 10,000 pieces delivered inside the 4-week window.
  • Unit cost held within 3.0% of the original quotation.
  • Inspection-related rejection stayed under 1.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
