Vape Juice quality control steps — a guide
Buyers come to us for vape juice after a bad quarter: dead stock on one side, empty shelves on the other. The cause is usually the same, an assortment built from a catalogue instead of from sell-through data. This page explains how we rebuild that balance for convenience store chains.

Reading a quotation properly
A vape juice programme only works when three numbers agree: your shelf price, your reorder cycle and your defect tolerance. Change one and the plan moves. We build assortments around those three and we say so up front rather than after the invoice.
Custom printing raises the unit price and lowers the marketing cost. For convenience store chains the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
Currency moves more than most buyers expect over a twelve month supply plan. We quote in USD and hold the price for 30 days from confirmation so your margin calculation is not guesswork.
Quality control, in plain terms
Every batch is pulled from running production, not from a display shelf. We check draw resistance, airflow balance, charge behaviour, leak performance after a temperature shift, finish quality and carton integrity, and we keep the pull records against the order number.
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.
What your market will ask for
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.
Labels are where good orders go wrong. Nicotine warnings, child-resistant closures, batch coding and market-specific text all have to be correct before the pallet leaves. We prepare test reports, declaration of conformity and safety data sheets for each shipment and we ask for your destination list early so artwork matches the market.
- Document pack prepared per destination market
- Consolidated or split shipping, quoted both ways
- Mixed SKU cartons to spread first-order risk
- Batch codes traceable from carton back to production date
- Reference sample retained from every batch
- Artwork proof plus physical dummy for custom packaging
Shipping without surprises
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 15 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
We can consolidate mixed orders of vape juices into one shipment. Consolidation saves freight but adds handling days, so we quote both a consolidated and a split option and let you choose.

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