Certification Documents For Vape Coil
We ship vape coils to distributors, chain buyers and independent shops. What follows is the material we normally cover in a first conversation: what we hold in stock, how we test it, how it ships, and what happens when a carton arrives damaged.

What happens when something goes wrong
There is no shortage of suppliers quoting vape coil. The scarce thing is a supplier who will tell you which SKU to drop. We have been shipping vape coils long enough to know that the honest answer is usually a shorter list, and that is the answer we give.
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.
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.
What we test before a carton is sealed
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.
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.
Building an assortment that actually turns
A practical starting order for online vape stores is 240 units across two or three SKUs, not 240 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
We keep a short list of approved configurations for vape coils. Anything outside that list is possible, but it becomes a custom run with a custom lead time, and we quote it as such rather than pretending everything is standard.
- Batch codes traceable from carton back to production date
- Cartons drop-tested and pallet-counted for clean freight
- Seven-day defect reporting with replace-or-credit
- Document pack prepared per destination market
- Specification locked in writing before production starts
- Standing reorder schedule with a fixed cut-off
Getting the carton there intact
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 30 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
Transit times move with the season. Book space early for Q4 and around Chinese New Year, when factory output pauses for two to three weeks and freight rates tighten at the same time.

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.
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.
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.
