Choosing THC Vape build mistakes
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.

What happens when something goes wrong
We work with online vape stores 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.
Returns are handled as data, not as complaints. Every reported failure is logged by mode and by batch, and the pattern is reviewed monthly with the factory.
Reorders are the real test of a supplier. If the second shipment does not match the first, the relationship is over regardless of price, so we treat the reorder as the actual deliverable.
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 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.
Where the margin really sits
Custom printing raises the unit price and lowers the marketing cost. For online vape stores the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
Freight is quoted separately and honestly. Bundling it into the unit price looks tidy and hides the one line that changes most often between shipments.
- Mixed SKU cartons to spread first-order risk
- Standing reorder schedule with a fixed cut-off
- Seven-day defect reporting with replace-or-credit
- Named account contact who has handled the product
- Reference sample retained from every batch
- Cartons drop-tested and pallet-counted for clean freight
The checks behind every shipment
We photograph the packing station during production for volume orders. It is a small thing, but it settles most arguments about what was actually in the carton before it was sealed.
12 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.

Frequently asked
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.
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.
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.
