Vape Juice sample testing protocol — a guide
Vape Juice is a specification decision before it is a price decision. Get the resistance, the capacity and the packaging right and the price conversation becomes short. Get them wrong and no discount will rescue the order.

How orders move from factory to shelf
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.
Freight on vape juices is driven by volume more than weight. Cartons are designed to hit a clean pallet count, which is why a slightly denser pack can cut your landed cost by more than a discount on the unit price ever would.
Transit times move with the season. Book space early for Q4 and around Chinese New Year, when factory output pauses for two to three weeks and freight rates tighten at the same time.
Choosing the core line
We source vape juices from a small group of factories we have worked with for years. That means a specification can be held across repeat orders instead of being re-qualified from scratch every quarter. Consistency is a boring selling point and it is also the entire game.
A practical starting order for B2B buyers is 100 units across two or three SKUs, not 100 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
What your market will ask for
We keep batch codes traceable from carton to production date. When a market authority asks for traceability, a supplier who cannot produce it in an hour becomes a liability very quickly.
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.
- Reference sample retained from every batch
- Artwork proof plus physical dummy for custom packaging
- Mixed SKU cartons to spread first-order risk
- Document pack prepared per destination market
- Specification locked in writing before production starts
- Private label files archived for future rebrands
After-sales, replacements and reorders
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.
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.

None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
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.
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 100 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 300 units because of setup time on the line.
