THC Vape sample testing protocol for the EU market
This page is for former smokers who want a working answer on specification, price and lead time before they commit a purchase order. We have written the detail down so nobody has to sit through a sales call to extract it.

Quality control, in plain terms
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 former smokers 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.
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.
A 0.5 percent defect rate sounds excellent until it lands on a 600 unit order and you are handling three returns in a week. We quote realistic rates per category and we credit in advance for the known failure modes.
Sell-through notes for the shop floor
Seasonality in THC vape products is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
Photography matters for online listings. Shoot on a neutral background with the device at a slight angle, show the pack alongside the unit, and keep the same framing across the range so the grid reads as a family.
Where the margin really sits
We publish a realistic band of 3.18 to 10.28 per unit for standard configurations at 200 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 former smokers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
- Cartons drop-tested and pallet-counted for clean freight
- Reference sample retained from every batch
- Mixed SKU cartons to spread first-order risk
- Named account contact who has handled the product
- Standing reorder schedule with a fixed cut-off
- Private label files archived for future rebrands
How orders move from factory to shelf
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 15 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
Documentation travels with the goods: commercial invoice, packing list, and the certificate set for your market. We send a scanned copy before dispatch so your broker can clear the file in advance.

Frequently asked
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 200 units. We would rather you handle the sample than approve a specification from a photograph.
How long does production take?
Around 15 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.
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.
