Sourcing Vape Juice: sample testing protocol explained
Vape Juice sits in a crowded price band, and the cheapest quote on the sheet is rarely the cheapest unit on your shelf. Everything below is built around reorder rate, defect rate and cash conversion rather than headline unit price.

How we structure a first order
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.
Factory capacity matters more than factory size. A line that can hold a tolerance across 5,000 units is worth more than a showroom that can produce 50,000 on paper. We qualify capacity by running a repeat order and measuring the drift.
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.
Merchandising a small range well
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.
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.
The reorder is the real test
Technical questions usually arrive at the worst possible moment, which is why we answer them on WhatsApp as well as email. A photo and a two line message resolves most issues faster than a ticket.
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.
- Named account contact who has handled the product
- Consolidated or split shipping, quoted both ways
- Standing reorder schedule with a fixed cut-off
- Cartons drop-tested and pallet-counted for clean freight
- Document pack prepared per destination market
- Mixed SKU cartons to spread first-order risk
Unit price versus landed cost
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.
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.
Specification summary
| Volume | 10 ml |
| Strength | 3 mg |
| Base ratio | 70/30 VG-PG |
| Flavour range | 48 profiles |
| Closure | Child resistant |
| Bottle | PET |
| Minimum order | 100 units per SKU, mixed cartons allowed |

We would rather lose an order at quotation stage than explain a mismatch after delivery, which is why the specification conversation comes before the price conversation.
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.
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 long does production take?
Around 25 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
