THC Vape commercial invoice for B2B buyers
Buyers come to us for THC vape after a bad quarter: dead stock on one side, empty shelves on the other. The cause is usually the same, an assortment built from a catalogue instead of from sell-through data. This page explains how we rebuild that balance for retail buyers.

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 retail 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.
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.
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.
Where the margin really sits
Unit price breaks usually land at 60, 240 and 480 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 3.27 to 9.52 per unit for standard configurations at 60 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Merchandising a small range well
Staff knowledge converts better than any poster. If your team can explain the difference between two coils in one sentence, the step-up SKU sells itself.
Seasonality in THC vape products is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
- Private label files archived for future rebrands
- Artwork proof plus physical dummy for custom packaging
- Batch codes traceable from carton back to production date
- Specification locked in writing before production starts
- Named account contact who has handled the product
- Reference sample retained from every batch
What your market will ask for
Regulation for THC vape products differs by country and sometimes by state. We do not pretend to be your lawyer, but we do keep the document pack current and we will tell you when a configuration cannot legally enter a market you have named.
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.

Frequently asked
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.
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 60 units. We would rather you handle the sample than approve a specification from a photograph.
