O-Ring for a Hospital Procurement Team in Russia
A Hospital Procurement Team approached us with a o-ring requirement for the Russia market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Shrinkage that only showed up after the first wash
- Shade drift between the approved lab dip and the bulk lot
- Elastic that lost recovery after three washes
What we specified
| Item | O-Ring |
|---|---|
| Client type | A Hospital Procurement Team |
| Market | Russia |
| Order volume | 5,000 pieces across 6 specifications |
| Base material | Genuine Leather |
| Standard size | 6 mm Width |
| Finish | Piece-Dyed Finish |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | ISO 14001 |
How it was resolved
- We rebuilt the specification around Genuine Leather and locked the tolerance before bulk.
- The finish was moved to Glossy Enamel Coating after strike-off tests showed better durability.
- A pre-production sample was approved and retained 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.
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 0.5%.
- The specification is now 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.
