How to source Vape Juice supplier with COA
We work with convenience store chains 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.

Quality control, in plain terms
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 convenience store chains 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.
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.
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.
Reading a quotation properly
Payment terms for new accounts are normally a deposit with the balance against the bill of lading. Established buyers on a repeat schedule can move to terms after three clean shipments.
Unit price breaks usually land at 300, 800 and 1600 pieces. Between those steps the cost curve flattens, which is why pushing a 200 unit order to 500 often costs less per unit than buyers expect.
Merchandising a small range well
Bundle a device with a consumable and the reorder rhythm changes from occasional to weekly. That single merchandising decision often does more for monthly revenue than a price promotion.
Shelf position decides velocity as much as price. Keep vape juices at eye level, one facing per SKU, and rotate the trial line every quarter so the display keeps earning attention.
- Artwork proof plus physical dummy for custom packaging
- Batch codes traceable from carton back to production date
- Document pack prepared per destination market
- Mixed SKU cartons to spread first-order risk
- Standing reorder schedule with a fixed cut-off
- Named account contact who has handled the product
Paperwork, labelling and market rules
If you sell into a market that requires child-resistant packaging, say so at quotation stage. Retrofitting a CR closure onto a finished bottle design usually means a new mould and a four week delay.
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.

Frequently asked
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.
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.
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 300 units. We would rather you handle the sample than approve a specification from a photograph.
