Case Study: Downpipe Supply for a national parts importer in Southeast Asia

Downpipe for A national parts importer in Southeast Asia

A national parts importer came to us with a downpipe programme for Southeast Asia. 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

  • Premature wear on the first batch
  • A fitment that looked right on paper and failed on the bench
  • A supplier who changed material without saying so

Volume20,000 pieces across 6 specifications

How it was resolved

  1. The specification was rebuilt around Carbon Steel 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.

Downpipe production run

Result

  • 20,000 pieces delivered inside the 5-week window.
  • Unit cost held within 2.0% 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

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.
