Brake Fluid Reservoir for An e-commerce seller in West Africa
An e-commerce seller came to us with a brake fluid reservoir programme for West 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
- Warranty claims traced back to a single lot
- Documentation that arrived after the container shipped
- Lead time that slipped twice before bulk started
What was specified
| Part | Brake Fluid Reservoir |
|---|---|
| Client | An e-commerce seller |
| Market | West Africa |
| Volume | 20,000 pieces across 6 specifications |
| Base material | EPDM Rubber |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | IATF 16949 |
How it was resolved
- The specification was rebuilt around EPDM Rubber 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 5-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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
