Choosing Vape Coil TPD with COA
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.

How we structure a first order
Ordering vape coil is not difficult. Ordering vape coil that sell through without a return queue behind them is the part most buyers underestimate, and it is where we spend our time. We supply online vape stores in European and North American markets with core lines that turn over predictably, and we keep the specification list short enough for your team to actually manage.
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.
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.
Batch consistency and why it matters
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.
10 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.
Compliance without the last-minute scramble
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.
Advertising rules are stricter than product rules in most markets. Claims about cessation, health or comparative performance should stay off packaging and off your product pages unless your legal team has signed them off.
- Document pack prepared per destination market
- Private label files archived for future rebrands
- Reference sample retained from every batch
- Batch codes traceable from carton back to production date
- Standing reorder schedule with a fixed cut-off
- Cartons drop-tested and pallet-counted for clean freight
Support that answers the question
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.
We keep the specification sheet for every order on file. Two years later, when a customer asks whether a pod is compatible, the answer is a lookup rather than a guess.

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.
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.
Can you ship to multiple locations?
Yes. Split shipments are quoted separately because consolidation and splitting price differently. Tell us the destination list at quotation stage and we will show both options.
