THC Vape quality control steps — a FAQ

We work with brand owners 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.

Support that answers the question

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 the specification sheet for every order on file. Two years later, when a customer asks whether a pod is compatible, the answer is a lookup rather than a guess.

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.

Transit, consolidation and timing

We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 15 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.

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.

For brand owners, the practical answer is usually a shorter range: two core lines, one step-up, one trial SKU. Everything else is inventory risk wearing a nice finish.

What we test before a carton is sealed

Every batch is pulled from running production, not from a display shelf. We check draw resistance, airflow balance, charge behaviour, leak performance after a temperature shift, finish quality and carton integrity, and we keep the pull records against the order number.

11 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.

  • Mixed SKU cartons to spread first-order risk
  • Standing reorder schedule with a fixed cut-off
  • Batch codes traceable from carton back to production date
  • Private label files archived for future rebrands
  • Document pack prepared per destination market
  • Consolidated or split shipping, quoted both ways

Assortment planning without the guesswork

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.

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.

We would rather lose an order at quotation stage than explain a mismatch after delivery, which is why the specification conversation comes before the price conversation.

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.

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.
