Sourcing Vape Coil: ISO factory audit explained
We work with online vape stores 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.

Sell-through notes for the shop floor
This page is for online vape stores who want a working answer on specification, price and lead time before they commit a purchase order. We have written the detail down so nobody has to sit through a sales call to extract it.
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.
Seasonality in vape coils is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
The checks behind every shipment
A 0.5 percent defect rate sounds excellent until it lands on a 600 unit order and you are handling three returns in a week. We quote realistic rates per category and we credit in advance for the known failure modes.
We photograph the packing station during production for volume orders. It is a small thing, but it settles most arguments about what was actually in the carton before it was sealed.
How we structure a first order
We source vape coils 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.
Colour range is where assortments quietly die. Six finishes look impressive in a brochure and disastrous on a shelf with 40 cm of space. We recommend two finishes per core SKU and let the trial line carry the novelty.
- Mixed SKU cartons to spread first-order risk
- Document pack prepared per destination market
- Seven-day defect reporting with replace-or-credit
- Consolidated or split shipping, quoted both ways
- Cartons drop-tested and pallet-counted for clean freight
- Named account contact who has handled the product
Where the margin really sits
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.
Unit price breaks usually land at 240, 600 and 1200 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
| Resistance | 0.15 ohm |
| Build | Single wire |
| Wicking | Organic cotton |
| Fitment | Press-fit |
| Pack size | 3 per pack |
| Compatibility | Brand-specific |
| Minimum order | 200 units per SKU, mixed cartons allowed |
| Lead time | 22 working days after artwork approval |
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
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.
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 240 units. We would rather you handle the sample than approve a specification from a photograph.
How long does production take?
Around 28 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.
