THC Vape COPQ in bulk guide
We work with former 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.

Batch consistency and why it matters
We ship THC vape products to distributors, chain buyers and independent shops. What follows is the material we normally cover in a first conversation: what we hold in stock, how we test it, how it ships, and what happens when a carton arrives damaged.
Battery safety is not a marketing line. Cells are matched by capacity and internal resistance before assembly, charging boards are checked for cut-off voltage, and any unit that fails the cut-off test never reaches packing.
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.
Lead times, freight and landed cost
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 12 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
Documentation travels with the goods: commercial invoice, packing list, and the certificate set for your market. We send a scanned copy before dispatch so your broker can clear the file in advance.
Compliance without the last-minute scramble
Age verification is not only a website problem. Retail packaging, shelf placement and staff scripting all carry compliance weight, and auditors increasingly ask for evidence of all three.
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.
- Specification locked in writing before production starts
- Seven-day defect reporting with replace-or-credit
- Cartons drop-tested and pallet-counted for clean freight
- Batch codes traceable from carton back to production date
- Reference sample retained from every batch
- Private label files archived for future rebrands
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.
We source THC vape products from a small group of factories we have worked with for years. That means a specification can be held across repeat orders instead of being re-qualified from scratch every quarter. Consistency is a boring selling point and it is also the entire game.
Specification summary
| Volume | 0.5 ml |
| Hardware | Cotton core |
| Thread | 510 thread |
| Airflow | Fixed |
| Window | Full glass |
| Packaging | Blister |
| Minimum order | 50 units per SKU, mixed cartons allowed |
| Lead time | 30 working days after artwork approval |
None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
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.
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.
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 50 units. We would rather you handle the sample than approve a specification from a photograph.
