How to source THC Vape port inspect with COA
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.

Assortment planning without the guesswork
THC Vape is a specification decision before it is a price decision. Get the resistance, the capacity and the packaging right and the price conversation becomes short. Get them wrong and no discount will rescue the order.
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.
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.
Quality control, in plain terms
14 separate checks run before a carton is sealed: electrical, mechanical, leak, finish and packaging. Anything outside tolerance is quarantined the same day and reported to you, rather than shipped with a hope and a discount.
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.
Turning shelf space into repeat visits
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.
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.
- Reference sample retained from every batch
- Batch codes traceable from carton back to production date
- Consolidated or split shipping, quoted both ways
- Specification locked in writing before production starts
- Mixed SKU cartons to spread first-order risk
- Cartons drop-tested and pallet-counted for clean freight
Unit price versus landed cost
We publish a realistic band of 3.43 to 9.88 per unit for standard configurations at 240 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Currency moves more than most buyers expect over a twelve month supply plan. We quote in USD and hold the price for 30 days from confirmation so your margin calculation is not guesswork.

Frequently asked
What is the minimum order for THC vape?
Standard configurations start at 240 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 600 units because of setup time on the line.
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.
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 240 units. We would rather you handle the sample than approve a specification from a photograph.
