Commercial terms
Currency movement over a ninety day cycle can outweigh the difference between two competing quotations.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (163 units) | Tier 1 | 21-30 days |
| Pallet (712 units) | Tier 2 | 21-30 days |
| Container (18370 units) | Tier 3 | 7-12 days |
Frequently asked questions
How often should Nex 4 be cleaned?
A quick contact clean every week or two, with a fuller clean monthly, suits most usage patterns.
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.
Can packaging be adjusted for our market?
Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.
Final word
Start with one change, measure it over a quarter, then decide whether it deserves to become policy.
