How to source THC Vape leak test for importers
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.

Building an assortment that actually turns
We work with first-time buyers who order between a few hundred and a few thousand units at a time, and we treat both ends the same way: a written specification, a sample you approve, and a production run that matches the sample.
When you compare suppliers for THC vape, ask for the last three production dates on the same SKU. If the answers are vague, the specification is not being held and the next batch will not match the sample you approved.
Most first-time buyers arrive with a spreadsheet and leave with too many SKUs. The fix is not a bigger catalogue, it is a narrower core. We normally propose three tiers: a volume line that carries the shelf, a step-up line that lifts basket value, and one trial SKU that tells you what to order next season.
Transit, consolidation and timing
For repeat buyers we hold a shipping schedule rather than shipping on request. A fixed weekly cut-off means your reorder lands before the shelf empties instead of after.
If you dropship, we can label cartons to your format and omit our documentation from the outer box. It is a small operational detail that decides whether your customer sees a supplier or a partner.
Where the margin really sits
We publish a realistic band of 3.55 to 9.39 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 first-time buyers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
- Consolidated or split shipping, quoted both ways
- Document pack prepared per destination market
- Artwork proof plus physical dummy for custom packaging
- Named account contact who has handled the product
- Seven-day defect reporting with replace-or-credit
- Batch codes traceable from carton back to production date
Where defects actually come from
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.
9 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.

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.
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.
What is the minimum order for THC vape?
Standard configurations start at 200 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 500 units because of setup time on the line.
