Vape Coil QC report: with full documents
Vape Coil 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.

Batch consistency and why it matters
Vape Coil is a specification decision before it is a price decision. Get the resistance, the capacity and the packaging right and the price conversation becomes short. Get them wrong and no discount will rescue the order.
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.
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.
Lead times, freight and landed cost
For repeat buyers we hold a shipping schedule rather than shipping on request. A fixed weekly cut-off means your reorder lands before the shelf empties instead of after.
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 22 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
What a sensible opening order looks like
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.
Most first-time buyers arrive with a spreadsheet and leave with too many SKUs. The fix is not a bigger catalogue, it is a narrower core. We normally propose three tiers: a volume line that carries the shelf, a step-up line that lifts basket value, and one trial SKU that tells you what to order next season.
- Mixed SKU cartons to spread first-order risk
- Consolidated or split shipping, quoted both ways
- Artwork proof plus physical dummy for custom packaging
- Batch codes traceable from carton back to production date
- Document pack prepared per destination market
- Reference sample retained from every batch
Price breaks and payment terms
Custom printing raises the unit price and lowers the marketing cost. For first-time buyers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
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.

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 200 units. We would rather you handle the sample than approve a specification from a photograph.
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.
