Choosing Vape Juice leak test FAQ
We ship vape juices 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.

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.
How we structure a first order
When you compare suppliers for vape juice, ask for the last three production dates on the same SKU. If the answers are vague, the specification is not being held and the next batch will not match the sample you approved.
We keep a short list of approved configurations for vape juices. Anything outside that list is possible, but it becomes a custom run with a custom lead time, and we quote it as such rather than pretending everything is standard.
Price breaks and payment terms
A landed cost sheet for vape juice 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.
- Specification locked in writing before production starts
- Named account contact who has handled the product
- Seven-day defect reporting with replace-or-credit
- Consolidated or split shipping, quoted both ways
- Cartons drop-tested and pallet-counted for clean freight
- Mixed SKU cartons to spread first-order risk
Keeping the second shipment identical
Every account gets a named contact who has actually seen the product. Being passed between three people to answer one question about a coil resistance is the fastest way to lose a buyer, so we do not organise support that way.
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.

Frequently asked
Can you ship to multiple locations?
Yes. Split shipments are quoted separately because consolidation and splitting price differently. Tell us the destination list at quotation stage and we will show both options.
What is the minimum order for vape juice?
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.
