Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (180 units) | Tier 1 | 30-45 days |
| Pallet (1722 units) | Tier 2 | 30-45 days |
| Container (7446 units) | Tier 3 | 14-21 days |
Frequently asked questions
Why does batch traceability matter for Nex 4?
It limits the scope of any future quality action to the affected batch instead of the whole range.
Can packaging be adjusted for our market?
Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.
Is documentation provided for customs?
Commercial invoice, packing list and the relevant certificates are supplied; the importer's broker handles the declaration.
What happens if a batch fails inspection?
The agreed procedure normally covers replacement of affected units or credit against the next order, documented before shipment.
Final word
The buyers who do this well are not luckier; they are simply more consistent about the basics.
