How to Source Esco Bars Havana 4: Coil Compatibility
Published 2026 · VapeWholesaleHub trade desk
Coil compatibility decides whether Havana 4 becomes a repeat purchase product or a one off sale.
The Havana 4 has settled into a stable position in the range, which makes coil compatibility the natural next question for distributors.
Retail staff rarely ask about coil compatibility directly, but their questions almost always lead back to it.
Why coil compatibility matters on the Havana 4
Clear cross reference charts reduce counter returns caused by customers buying the wrong resistance.
Consistency across batches matters more than peak performance for Havana 4, and coil compatibility is where inconsistency first appears.
Mesh structures tend to give more consistent flavour over the life of the coil.

Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.

|---|---|---|
| Carton (99 units) | Tier 1 | 7-12 days |
| Pallet (1959 units) | Tier 2 | 14-21 days |
| Container (18606 units) | Tier 3 | 21-30 days |
