Vehicle Scent Diffuser Specification Example for Agricultural Trailers: Drilled and Slotted
Vehicle Scent Diffuser Specification Example for Agricultural Trailers: Drilled and Slotted
This is a worked specification for vehicle scent diffuser 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 agricultural trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.

Example specification
| Item | Vehicle Scent Diffuser |
|---|---|
| Application | Agricultural Trailers |
| Version | Drilled and Slotted |

| Finish | as machined |
| MOQ | 3,000 pieces per specification |
| Sampling | 14 working days, 5 days per revision |
| Compliance | RoHS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Chromed Steel, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- shot blasting
- powder coating
- heat treatment
- laser cutting
- ultrasonic cleaning
- sintering
Where this example applies
Programmes that run drilled and slotted most often specify this build for agricultural trailers. Related applications include municipal fleets, fleet maintenance, light trucks, workshop replacements, delivery vans.
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
What testing is included?
Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.
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 14 working days, and each revision round adds about 5 days once you have seen the first piece.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
