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 (116 units) | Tier 1 | 14-21 days |
| Pallet (1461 units) | Tier 2 | 21-30 days |
| Container (6293 units) | Tier 3 | 14-21 days |
Frequently asked questions
Why does batch traceability matter for Rexa 4?
It limits the scope of any future quality action to the affected batch instead of the whole range.
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.
Do you support long term supply agreements?
Yes, rolling agreements with defined review points work better for both sides than rigid annual commitments.
Final word
The buyers who do this well are not luckier; they are simply more consistent about the basics.
