Downpipe for A courier company in Southern Africa
A courier company came to us with a downpipe programme for Southern Africa. 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
- Reorders that did not match the approved sample
- A fitment that looked right on paper and failed on the bench
- Packing that arrived crushed at the port

What was specified
| Part | Downpipe |
|---|---|
| Client | A courier company |
| Market | Southern Africa |
| Volume | 10,000 pieces across 4 specifications |
| Base material | Forged Aluminium |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | RoHS |
How it was resolved
- The specification was rebuilt around Forged Aluminium 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
- 10,000 pieces delivered inside the 10-week window.
- Unit cost held within 1.5% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.

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