THC Vape audit and factory check for small batches
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 distributors 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.

Quality control, in plain terms
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.
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.
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.
Paperwork, labelling and market rules
Age verification is not only a website problem. Retail packaging, shelf placement and staff scripting all carry compliance weight, and auditors increasingly ask for evidence of all three.
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.
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.
Freight is quoted separately and honestly. Bundling it into the unit price looks tidy and hides the one line that changes most often between shipments.
- Cartons drop-tested and pallet-counted for clean freight
- Document pack prepared per destination market
- Seven-day defect reporting with replace-or-credit
- Mixed SKU cartons to spread first-order risk
- Private label files archived for future rebrands
- Batch codes traceable from carton back to production date
Getting the carton there intact
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 28 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
Freight on THC vape products is driven by volume more than weight. Cartons are designed to hit a clean pallet count, which is why a slightly denser pack can cut your landed cost by more than a discount on the unit price ever would.

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
What documents come with a shipment?
Commercial invoice, packing list, and the certificate pack for your market: test reports, declaration of conformity and safety data sheets. We send scans before dispatch so your broker can pre-clear the file.
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.
