Published 2026 · VapeWholesaleHub trade desk

Distributors reviewing their Royal 4 range usually find that coil compatibility explains most of the variance in results between accounts.

A written internal standard for coil compatibility makes onboarding new account managers far quicker and reduces avoidable errors.

Why coil compatibility matters on the Royal 4

Clear cross reference charts reduce counter returns caused by customers buying the wrong resistance.

Consistency across batches matters more than peak performance for Royal 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

Volume commitments work best when they are structured as a rolling target rather than a single fixed number.

Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.

Volume tier	Indicative unit level	Lead time
Carton (110 units)	Tier 1	7-12 days
Pallet (504 units)	Tier 2	30-45 days
Container (11302 units)	Tier 3	30-45 days

All figures above are indicative working ranges used for planning. Final specification and commercial terms are confirmed in writing before any deposit.
