Sport Bumper Specification Example for Light Trucks: Drilled and Slotted

This is a worked specification for sport bumper in a drilled and slotted programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The drilled and slotted version exists because the duty cycle on light trucks is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.

  2. Fix the base material in writing — Chromed Steel, in this example.

  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

What happens if a lot fails inspection?

The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.

Can you match an existing sample?

Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.

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