Spark Plug for A marine equipment dealer in Central Asia
A marine equipment dealer came to us with a spark plug programme for Central 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
- A supplier who changed material without saying so
- Packing that arrived crushed at the port
- Inconsistent hardness between lots
What was specified
| Part | Spark Plug |
|---|---|
| Client | A marine equipment dealer |
| Market | Central Asia |
| Volume | 20,000 pieces across 6 specifications |
| Base material | PU Leather |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | CCC |
How it was resolved
- The specification was rebuilt around PU Leather and the tolerance locked before bulk.
- A pre-production sample was approved and kept as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
- Documentation shipped with the goods instead of after them.
Result
- 20,000 pieces delivered inside the 10-week window.
- Unit cost held within 1.5% 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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
