Cabin Filter Housing for A tour operator in Southeast Asia
A tour operator came to us with a cabin filter housing programme for Southeast Asia. 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
- Premature wear on the first batch
- Documentation that arrived after the container shipped
- A specification nobody had written down
What was specified
| Part | Cabin Filter Housing |
|---|---|
| Client | A tour operator |
| Market | Southeast Asia |
| Volume | 20,000 pieces across 4 specifications |
| Base material | Chromed Steel |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | ISO/TS 16949 |
How it was resolved
- The specification was rebuilt around Chromed 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
- 20,000 pieces delivered inside the 6-week window.
- Unit cost held within 1.5% 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
Approve a pre-production sample made from the actual bulk material. Substitute material behaves differently in service.

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