Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (122 units) | Tier 1 | 7-12 days |
| Pallet (1450 units) | Tier 2 | 14-21 days |
| Container (12682 units) | Tier 3 | 14-21 days |
Frequently asked questions
Which coil resistance suits Nex 4 best?
Higher resistance suits tighter draws and salt liquids; lower resistance suits open airflow and freebase blends.
Can packaging be adjusted for our market?
Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.
Do you support long term supply agreements?
Yes, rolling agreements with defined review points work better for both sides than rigid annual commitments.
Is documentation provided for customs?
Commercial invoice, packing list and the relevant certificates are supplied; the importer's broker handles the declaration.
