Serpentine Belt for A construction contractor in Latin America
A construction contractor came to us with a serpentine belt programme for Latin 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
- A supplier who changed material without saying so
- A fitment that looked right on paper and failed on the bench
- Documentation that arrived after the container shipped

What was specified
| Part | Serpentine Belt |
|---|---|
| Client | A construction contractor |
| Market | Latin America |
| Volume | 50,000 pieces across 2 specifications |
| Base material | Powder Coated Steel |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | DOT |
How it was resolved
- The specification was rebuilt around Powder Coated Steel 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
- 50,000 pieces delivered inside the 6-week window.
- Unit cost held within 3.0% 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.
