Sourcing THC Vape: supplier communication guide
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.

Paperwork, labelling and market rules
We work with vape shop owners 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.
If you sell into a market that requires child-resistant packaging, say so at quotation stage. Retrofitting a CR closure onto a finished bottle design usually means a new mould and a four week delay.
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.
What we test before a carton is sealed
Leak complaints almost always trace back to one of three things: an over-torqued centre post, a seal that sat in a hot container, or a fill volume pushed past the design limit. We cap fill volume slightly below maximum for exactly that reason.
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.
After-sales, replacements and reorders
Returns are handled as data, not as complaints. Every reported failure is logged by mode and by batch, and the pattern is reviewed monthly with the factory.
The replacement policy is deliberately simple: report within seven days of delivery with photos and the batch code, and we replace or credit at the next shipment. We do not argue about a defect we can see in a photograph.
- Private label files archived for future rebrands
- Cartons drop-tested and pallet-counted for clean freight
- Consolidated or split shipping, quoted both ways
- Seven-day defect reporting with replace-or-credit
- Document pack prepared per destination market
- Specification locked in writing before production starts
Where the margin really sits
We publish a realistic band of 3.30 to 9.82 per unit for standard configurations at 300 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Custom printing raises the unit price and lowers the marketing cost. For vape shop owners the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.

We would rather lose an order at quotation stage than explain a mismatch after delivery, which is why the specification conversation comes before the price conversation.
Frequently asked
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.
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.
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.
