Diesel Fuel Enhancer Specification Example for Agricultural Trailers: Premium Line
Diesel Fuel Enhancer Specification Example for Agricultural Trailers: Premium Line
This is a worked specification for diesel fuel enhancer 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 agricultural trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually reorders that did not match the approved sample.

Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 sampling on the finished lot.
- 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 2000 pieces per line.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the REACH-compliant build instead of a fresh interpretation.
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.
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.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
