Vape Coil sampling: pitfalls

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.

What we test before a carton is sealed

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 first-time buyers.

Battery safety is not a marketing line. Cells are matched by capacity and internal resistance before assembly, charging boards are checked for cut-off voltage, and any unit that fails the cut-off test never reaches packing.

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.

Paperwork, labelling and market rules

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.

Labels are where good orders go wrong. Nicotine warnings, child-resistant closures, batch coding and market-specific text all have to be correct before the pallet leaves. We prepare test reports, declaration of conformity and safety data sheets for each shipment and we ask for your destination list early so artwork matches the market.

For first-time buyers, the practical answer is usually a shorter range: two core lines, one step-up, one trial SKU. Everything else is inventory risk wearing a nice finish.

The reorder is the real test

For private label accounts we hold the artwork files and the approval record. Rebranding a line eighteen months later is then a file update instead of a redesign.

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.

  • Named account contact who has handled the product
  • Specification locked in writing before production starts
  • Seven-day defect reporting with replace-or-credit
  • Private label files archived for future rebrands
  • Standing reorder schedule with a fixed cut-off
  • Batch codes traceable from carton back to production date

Reading a quotation properly

We publish a realistic band of 0.56 to 2.57 per unit for standard configurations at 500 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.

Payment terms for new accounts are normally a deposit with the balance against the bill of lading. Established buyers on a repeat schedule can move to terms after three clean shipments.

Frequently asked

What is the minimum order for vape coil?

Standard configurations start at 500 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 1000 units because of setup time on the line.

Do you support private label?

We do. Send your artwork or your brand direction and we will return a digital proof, then a physical dummy for colour approval. Packaging files stay on record so a rebrand later is a file update rather than a redesign.

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.
