Expansion Valve for An e-commerce seller in Central America
An e-commerce seller came to us with a expansion valve programme for Central 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
- Inconsistent hardness between lots
- Documentation that arrived after the container shipped
- Packing that arrived crushed at the port
What was specified
| Part | Expansion Valve |
|---|---|
| Client | An e-commerce seller |
| Market | Central America |
| Volume | 20,000 pieces across 2 specifications |
| Base material | Aluminium Alloy |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | REACH |
How it was resolved
- The specification was rebuilt around Aluminium Alloy 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 4-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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
