Vape Juice inspection — with COA

There is no shortage of suppliers quoting vape juice. The scarce thing is a supplier who will tell you which SKU to drop. We have been shipping vape juices long enough to know that the honest answer is usually a shorter list, and that is the answer we give.

Shipping without surprises

Ordering vape juice is not difficult. Ordering vape juice that sell through without a return queue behind them is the part most buyers underestimate, and it is where we spend our time. We supply B2B buyers in European and North American markets with core lines that turn over predictably, and we keep the specification list short enough for your team to actually manage.

If you dropship, we can label cartons to your format and omit our documentation from the outer box. It is a small operational detail that decides whether your customer sees a supplier or a partner.

Damage in transit is nearly always a packing decision, not bad luck. Double-walled cartons, internal dividers and a drop-tested configuration cost a little more and save the argument at the other end.

What happens when something goes wrong

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.

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.

For B2B buyers, 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.

Where defects actually come from

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.

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.

  • Artwork proof plus physical dummy for custom packaging
  • Specification locked in writing before production starts
  • Reference sample retained from every batch
  • Mixed SKU cartons to spread first-order risk
  • Consolidated or split shipping, quoted both ways
  • Standing reorder schedule with a fixed cut-off

Getting the documents right

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.

Regulation for vape juices differs by country and sometimes by state. We do not pretend to be your lawyer, but we do keep the document pack current and we will tell you when a configuration cannot legally enter a market you have named.

Frequently asked

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.

What is the minimum order for vape juice?

Standard configurations start at 60 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 240 units because of setup time on the line.

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.
