THC Vape third-party testing — a tips
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.

Lead times, freight and landed cost
This page is for importers 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.
Transit times move with the season. Book space early for Q4 and around Chinese New Year, when factory output pauses for two to three weeks and freight rates tighten at the same time.
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.
What we test before a carton is sealed
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.
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.
Reading a quotation properly
Unit price breaks usually land at 200, 500 and 1000 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.
Custom printing raises the unit price and lowers the marketing cost. For importers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
- Specification locked in writing before production starts
- Reference sample retained from every batch
- Mixed SKU cartons to spread first-order risk
- Named account contact who has handled the product
- Artwork proof plus physical dummy for custom packaging
- Standing reorder schedule with a fixed cut-off
What a sensible opening order looks like
A practical starting order for importers is 200 units across two or three SKUs, not 200 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
Factory capacity matters more than factory size. A line that can hold a tolerance across 5,000 units is worth more than a showroom that can produce 50,000 on paper. We qualify capacity by running a repeat order and measuring the drift.

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