Vape Coil third-party testing with full documents
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.

Quality control, in plain terms
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.
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.
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.
What happens when something goes wrong
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.
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.
Building an assortment that actually turns
A practical starting order for online vape stores is 200 units across two or three SKUs, not 200 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
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.
- Cartons drop-tested and pallet-counted for clean freight
- Mixed SKU cartons to spread first-order risk
- Reference sample retained from every batch
- Batch codes traceable from carton back to production date
- Standing reorder schedule with a fixed cut-off
- Seven-day defect reporting with replace-or-credit
How the price is actually built
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.
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.
Specification summary

| Compatibility | Brand-specific |
| Minimum order | 100 units per SKU, mixed cartons allowed |

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 200 units. We would rather you handle the sample than approve a specification from a photograph.
How long does production take?
Around 25 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.
