Case Study: Wheel Speed Sensor Supply for an online marketplace seller in the Caribbean
Wheel Speed Sensor for An online marketplace seller in the Caribbean
An online marketplace seller came to us with a wheel speed sensor programme for the Caribbean. 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
- Reorders that did not match the approved sample
- Documentation that arrived after the container shipped

What was specified
| Part | Wheel Speed Sensor |
|---|---|
| Client | An online marketplace seller |
| Market | the Caribbean |
| Volume | 5,000 pieces across 6 specifications |
| Base material | Forged Aluminium |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | E-mark |
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
- 5,000 pieces delivered inside the 10-week window.
- Unit cost held within 3.0% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.

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