THC Vape defect rate — for 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 vape shop owners.

Keeping the second shipment identical
There is no shortage of suppliers quoting THC vape. The scarce thing is a supplier who will tell you which SKU to drop. We have been shipping THC vape products long enough to know that the honest answer is usually a shorter list, and that is the answer we give.
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.
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.
Unit price versus landed cost
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.
A landed cost sheet for THC vape has five lines: unit price, packaging, freight, duty and the cost of defects. Quoting only the first line is how buyers end up surprised at the fourth.
Choosing the core line
Colour range is where assortments quietly die. Six finishes look impressive in a brochure and disastrous on a shelf with 40 cm of space. We recommend two finishes per core SKU and let the trial line carry the novelty.
The first question we ask is not what you want to spend. It is what your customer already buys. Answer that and the THC vape list writes itself; skip it and you end up with a pallet of stock that photographs well and sells badly.
- Named account contact who has handled the product
- Batch codes traceable from carton back to production date
- Reference sample retained from every batch
- Mixed SKU cartons to spread first-order risk
- Cartons drop-tested and pallet-counted for clean freight
- Private label files archived for future rebrands
Shipping without surprises
Damage in transit is nearly always a packing decision, not bad luck. Double-walled cartons, internal dividers and a drop-tested configuration cost a little more and save the argument at the other end.
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.

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.
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 120 units. We would rather you handle the sample than approve a specification from a photograph.
