Case Study: Radar Detector Supply for a spare parts retailer in North America

Radar Detector for A spare parts retailer in North America

A spare parts retailer came to us with a radar detector programme for North America. 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
  • A specification nobody had written down
  • Packing that arrived crushed at the port

MarketNorth America
Volume2,000 pieces across 2 specifications
Base materialReinforced Nylon
Sampling rounds4
Delivery window6 weeks from PO to ex-factory
ComplianceTUV

How it was resolved

  1. The specification was rebuilt around Reinforced Nylon 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.

Radar Detector production run

Result

  • 2,000 pieces delivered inside the 6-week window.
  • Unit cost held within 4.5% 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.
