How to source THC Vape QC steps steps
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.

After-sales, replacements and reorders
This page is for online vape stores who want a working answer on specification, price and lead time before they commit a purchase order. We have written the detail down so nobody has to sit through a sales call to extract it.
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.
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.
Quality control, in plain terms
Flavour drift between batches is the quiet killer of repeat orders. We retain a sealed reference sample from every run so a complaint six weeks later can be compared against what actually left the building.
Leak complaints almost always trace back to one of three things: an over-torqued centre post, a seal that sat in a hot container, or a fill volume pushed past the design limit. We cap fill volume slightly below maximum for exactly that reason.
Paperwork, labelling and market rules
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.
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.
- Private label files archived for future rebrands
- Named account contact who has handled the product
- Reference sample retained from every batch
- Batch codes traceable from carton back to production date
- Seven-day defect reporting with replace-or-credit
- Document pack prepared per destination market
How the price is actually built
A landed cost sheet for THC vape has five lines: unit price, packaging, freight, duty and the cost of defects. Quoting only the first line is how buyers end up surprised at the fourth.
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.

If any of this is unclear, the fastest route is a message rather than a meeting. Send the market you sell into and the price band you work in, and you will get a specific answer instead of a brochure.
Frequently asked
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.
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 happens if part of the order is defective?
Report within seven days with photos and the batch code. Confirmed defects are replaced or credited on the next shipment. The failure is logged by mode and batch, and reviewed monthly with the factory.
