Vape Coil COPQ: pitfalls
A vape coil programme only works when three numbers agree: your shelf price, your reorder cycle and your defect tolerance. Change one and the plan moves. We build assortments around those three and we say so up front rather than after the invoice.

Unit price versus landed cost
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.
Unit price breaks usually land at 50, 200 and 400 pieces. Between those steps the cost curve flattens, which is why pushing a 200 unit order to 500 often costs less per unit than buyers expect.
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 checks behind every shipment
Cosmetic grading is written down, not argued about. Minor scuffs inside the tolerance band are accepted; anything that would make a customer put the unit back on the shelf is rejected. Your staff should never have to explain a finish defect to a paying customer.
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.
Shipping without surprises
Damage in transit is nearly always a packing decision, not bad luck. Double-walled cartons, internal dividers and a drop-tested configuration cost a little more and save the argument at the other end.
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.
- Specification locked in writing before production starts
- Batch codes traceable from carton back to production date
- Reference sample retained from every batch
- Named account contact who has handled the product
- Seven-day defect reporting with replace-or-credit
- Consolidated or split shipping, quoted both ways
Keeping the second shipment identical
The replacement policy is deliberately simple: report within seven days of delivery with photos and the batch code, and we replace or credit at the next shipment. We do not argue about a defect we can see in a photograph.
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.
Specification summary
| Resistance | 0.20 ohm |
| Build | Single wire |
| Wicking | Cotton bacon |
| Fitment | Threaded |
| Pack size | 3 per pack |
| Compatibility | Universal deck |
| Minimum order | 50 units per SKU, mixed cartons allowed |
| Lead time | 30 working days after artwork approval |
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
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.
Can you ship to multiple locations?
Yes. Split shipments are quoted separately because consolidation and splitting price differently. Tell us the destination list at quotation stage and we will show both options.
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.
