Off-Road Bumper Specification Example for Aftermarket Retail: Quick Fit Version

This is a worked specification for off-road bumper in a quick fit version 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 quick fit version version exists because the duty cycle on aftermarket retail is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually lead time that slipped twice before bulk started.

Questions buyers ask

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.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.

How long does sampling take?

Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.

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.

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