Vape Coil sample testing protocol — a checklist
Buyers come to us for vape coil after a bad quarter: dead stock on one side, empty shelves on the other. The cause is usually the same, an assortment built from a catalogue instead of from sell-through data. This page explains how we rebuild that balance for online vape stores.

The reorder is the real test
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.
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.
Simple habits that lift velocity
Shelf position decides velocity as much as price. Keep vape coils at eye level, one facing per SKU, and rotate the trial line every quarter so the display keeps earning attention.
Counter space is finite. Three well-chosen SKUs outsell nine crowded ones, and the empty space signals a curated range rather than a clearance table.
Transit, consolidation and timing
Documentation travels with the goods: commercial invoice, packing list, and the certificate set for your market. We send a scanned copy before dispatch so your broker can clear the file in advance.
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.
- Private label files archived for future rebrands
- Standing reorder schedule with a fixed cut-off
- Artwork proof plus physical dummy for custom packaging
- Reference sample retained from every batch
- Document pack prepared per destination market
- Specification locked in writing before production starts
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.
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.

Frequently asked
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.
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.
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.
