Idler Pulley for An e-commerce seller in the Middle East

An e-commerce seller came to us with a idler pulley programme for the Middle East. 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 fitment that looked right on paper and failed on the bench
  • A specification nobody had written down
  • Inconsistent hardness between lots

Marketthe Middle East
Volume2,000 pieces across 2 specifications
Base materialTitanium Alloy
Sampling rounds3
Delivery window10 weeks from PO to ex-factory
ComplianceE-mark

How it was resolved

  1. The specification was rebuilt around Titanium Alloy and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Result

  • 2,000 pieces delivered inside the 10-week window.
  • Unit cost held within 4.5% 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

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

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