Vape Coil free sale certificate in Shenzhen
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.

Where defects actually come from
If you are comparing three quotes for vape coil, compare the paperwork first. Test reports, artwork files, batch coding and the replacement clause tell you more about a supplier than the unit price on page one.
Flavour drift between batches is the quiet killer of repeat orders. We retain a sealed reference sample from every run so a complaint six weeks later can be compared against what actually left the building.
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.
Compliance without the last-minute scramble
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.
If you sell into a market that requires child-resistant packaging, say so at quotation stage. Retrofitting a CR closure onto a finished bottle design usually means a new mould and a four week delay.
Support that answers the question
Every account gets a named contact who has actually seen the product. Being passed between three people to answer one question about a coil resistance is the fastest way to lose a buyer, so we do not organise support that way.
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.
- Seven-day defect reporting with replace-or-credit
- Artwork proof plus physical dummy for custom packaging
- Document pack prepared per destination market
- Private label files archived for future rebrands
- Consolidated or split shipping, quoted both ways
- Specification locked in writing before production starts
Shipping without surprises
Freight on vape coils is driven by volume more than weight. Cartons are designed to hit a clean pallet count, which is why a slightly denser pack can cut your landed cost by more than a discount on the unit price ever would.
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.

Frequently asked
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 50 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.
How long does production take?
Around 30 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.
