Tie Rod End for An e-commerce seller in Eastern Europe

An e-commerce seller came to us with a tie rod end programme for Eastern Europe. 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

  • Warranty claims traced back to a single lot
  • A specification nobody had written down
  • Reorders that did not match the approved sample

What was specified

PartTie Rod End
ClientAn e-commerce seller
MarketEastern Europe
Volume2,000 pieces across 6 specifications
Base materialNylon 66
Sampling rounds2
Delivery window8 weeks from PO to ex-factory
ComplianceIATF 16949

How it was resolved

  1. The specification was rebuilt around Nylon 66 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 8-week window.
  • Unit cost held within 4.5% 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

Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
