THC Vape factory audit checklist for UK buyers
Ordering THC vape is not difficult. Ordering THC vape that sell through without a return queue behind them is the part most buyers underestimate, and it is where we spend our time. We supply B2B buyers in European and North American markets with core lines that turn over predictably, and we keep the specification list short enough for your team to actually manage.

How we structure a first order
We work with B2B buyers who order between a few hundred and a few thousand units at a time, and we treat both ends the same way: a written specification, a sample you approve, and a production run that matches the sample.
We source THC vape products from a small group of factories we have worked with for years. That means a specification can be held across repeat orders instead of being re-qualified from scratch every quarter. Consistency is a boring selling point and it is also the entire game.
Most B2B buyers arrive with a spreadsheet and leave with too many SKUs. The fix is not a bigger catalogue, it is a narrower core. We normally propose three tiers: a volume line that carries the shelf, a step-up line that lifts basket value, and one trial SKU that tells you what to order next season.
Getting the documents right
Artwork approval is a two stage process: a digital proof for text and layout, then a physical dummy for colour and finish. Skipping the dummy is the single most common cause of a reprint.
We keep batch codes traceable from carton to production date. When a market authority asks for traceability, a supplier who cannot produce it in an hour becomes a liability very quickly.
Where the margin really sits
The cheapest way to lower your cost per unit is usually to remove a SKU, not to negotiate a discount. Fewer lines means larger runs, fewer changeovers and a better price at the same quality.
A landed cost sheet for THC vape has five lines: unit price, packaging, freight, duty and the cost of defects. Quoting only the first line is how buyers end up surprised at the fourth.
- Private label files archived for future rebrands
- Batch codes traceable from carton back to production date
- Artwork proof plus physical dummy for custom packaging
- Reference sample retained from every batch
- Specification locked in writing before production starts
- Seven-day defect reporting with replace-or-credit
What we test before a carton is sealed
Flavour drift between batches is the quiet killer of repeat orders. We retain a sealed reference sample from every run so a complaint six weeks later can be compared against what actually left the building.
We photograph the packing station during production for volume orders. It is a small thing, but it settles most arguments about what was actually in the carton before it was sealed.

If any of this is unclear, the fastest route is a message rather than a meeting. Send the market you sell into and the price band you work in, and you will get a specific answer instead of a brochure.
Frequently asked
How do you handle repeat orders?
The specification is held on file against your account, so a reorder is a reference rather than a new brief. We recommend a standing schedule with a fixed weekly cut-off so stock lands before the shelf empties.
What happens if part of the order is defective?
Report within seven days with photos and the batch code. Confirmed defects are replaced or credited on the next shipment. The failure is logged by mode and batch, and reviewed monthly with the factory.
Do you support private label?
We do. Send your artwork or your brand direction and we will return a digital proof, then a physical dummy for colour approval. Packaging files stay on record so a rebrand later is a file update rather than a redesign.
