Sourcing THC Vape: third-party testing notes
We work with wholesale 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.

How we structure a first order
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.
We keep a short list of approved configurations for THC vape products. Anything outside that list is possible, but it becomes a custom run with a custom lead time, and we quote it as such rather than pretending everything is standard.
Sourcing trips still matter for volume buyers. Seeing the line, the ageing room and the packing station tells you in an hour what six emails cannot. We host visits by appointment and we do not stage them.
Unit price versus landed cost
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.
The cheapest way to lower your cost per unit is usually to remove a SKU, not to negotiate a discount. Fewer lines means larger runs, fewer changeovers and a better price at the same quality.
Quality control, in plain terms
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.
10 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.
- Consolidated or split shipping, quoted both ways
- Standing reorder schedule with a fixed cut-off
- Mixed SKU cartons to spread first-order risk
- Batch codes traceable from carton back to production date
- Document pack prepared per destination market
- Artwork proof plus physical dummy for custom packaging
Getting the carton there intact
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 22 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
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.

Frequently asked
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.
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.
