Off-Road Bumper Specification Example for Three-Wheelers: Load Rated Version

This is a worked specification for off-road bumper in a load rated 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 load rated version version exists because the duty cycle on three-wheelers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually packing that arrived crushed at the port.

Questions buyers ask

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SGS-compliant build instead of a fresh interpretation.

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.

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.

Tell us the model, the fitment and the quantity and we will hold a production slot for you.
