What your market will ask for
We work with first-time buyers 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.
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.
Regulation for vape coils differs by country and sometimes by state. We do not pretend to be your lawyer, but we do keep the document pack current and we will tell you when a configuration cannot legally enter a market you have named.
Sell-through notes for the shop floor
Staff knowledge converts better than any poster. If your team can explain the difference between two coils in one sentence, the step-up SKU sells itself.
Photography matters for online listings. Shoot on a neutral background with the device at a slight angle, show the pack alongside the unit, and keep the same framing across the range so the grid reads as a family.
Quality control, in plain terms
Battery safety is not a marketing line. Cells are matched by capacity and internal resistance before assembly, charging boards are checked for cut-off voltage, and any unit that fails the cut-off test never reaches packing.
14 separate checks run before a carton is sealed: electrical, mechanical, leak, finish and packaging. Anything outside tolerance is quarantined the same day and reported to you, rather than shipped with a hope and a discount.
- Seven-day defect reporting with replace-or-credit
- Cartons drop-tested and pallet-counted for clean freight
- Batch codes traceable from carton back to production date
- Named account contact who has handled the product
- Standing reorder schedule with a fixed cut-off
- Specification locked in writing before production starts
Support that answers the question
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.
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
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 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 15 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.
