THC Vape certification — workbook
If you are comparing three quotes for THC vape, compare the paperwork first. Test reports, artwork files, batch coding and the replacement clause tell you more about a supplier than the unit price on page one.

Support that answers the question
We work with adult smokers 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.
Technical questions usually arrive at the worst possible moment, which is why we answer them on WhatsApp as well as email. A photo and a two line message resolves most issues faster than a ticket.
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.
Labels, closures and traceability
Advertising rules are stricter than product rules in most markets. Claims about cessation, health or comparative performance should stay off packaging and off your product pages unless your legal team has signed them off.
Artwork approval is a two stage process: a digital proof for text and layout, then a physical dummy for colour and finish. Skipping the dummy is the single most common cause of a reprint.
How orders move from factory to shelf
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.
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.
- Seven-day defect reporting with replace-or-credit
- Batch codes traceable from carton back to production date
- Mixed SKU cartons to spread first-order risk
- Consolidated or split shipping, quoted both ways
- Artwork proof plus physical dummy for custom packaging
- Standing reorder schedule with a fixed cut-off
Where the margin really sits
Custom printing raises the unit price and lowers the marketing cost. For adult smokers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
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.

None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
Frequently asked
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 120 units. We would rather you handle the sample than approve a specification from a photograph.
How long does production take?
Around 15 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
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.
