Injection Valves Specification Example for Export Programmes: Premium Line

This is a worked specification for injection valves in a premium line 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 premium line version exists because the duty cycle on export programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

  3. List the dimensions that are actually controlled and the tolerance on each.

Questions buyers ask

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.

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 5 days once you have seen the first piece.

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 testing is included?

Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.

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