THC Vape factory audit checklist for UK buyers
If you are comparing three quotes for THC vape, compare the paperwork first. Test reports, artwork files, batch coding and the replacement clause tell you more about a supplier than the unit price on page one.

Lead times, freight and landed cost
A THC vape programme only works when three numbers agree: your shelf price, your reorder cycle and your defect tolerance. Change one and the plan moves. We build assortments around those three and we say so up front rather than after the invoice.
For repeat buyers we hold a shipping schedule rather than shipping on request. A fixed weekly cut-off means your reorder lands before the shelf empties instead of after.
If you dropship, we can label cartons to your format and omit our documentation from the outer box. It is a small operational detail that decides whether your customer sees a supplier or a partner.
Unit price versus landed cost
Unit price breaks usually land at 240, 600 and 1200 pieces. Between those steps the cost curve flattens, which is why pushing a 200 unit order to 500 often costs less per unit than buyers expect.
We publish a realistic band of 3.47 to 10.23 per unit for standard configurations at 240 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Support that answers the question
For private label accounts we hold the artwork files and the approval record. Rebranding a line eighteen months later is then a file update instead of a redesign.
We keep the specification sheet for every order on file. Two years later, when a customer asks whether a pod is compatible, the answer is a lookup rather than a guess.
- Document pack prepared per destination market
- Artwork proof plus physical dummy for custom packaging
- Standing reorder schedule with a fixed cut-off
- Batch codes traceable from carton back to production date
- Cartons drop-tested and pallet-counted for clean freight
- Reference sample retained from every batch
Batch consistency and why it matters
Every batch is pulled from running production, not from a display shelf. We check draw resistance, airflow balance, charge behaviour, leak performance after a temperature shift, finish quality and carton integrity, and we keep the pull records against the order number.
Battery safety is not a marketing line. Cells are matched by capacity and internal resistance before assembly, charging boards are checked for cut-off voltage, and any unit that fails the cut-off test never reaches packing.

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 long does production take?
Around 22 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
Can we order samples before committing?
Yes. Sample orders are shipped by air express and the cost is credited against your first production order above 240 units. We would rather you handle the sample than approve a specification from a photograph.
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.
