Frequently asked questions
Why does batch traceability matter for Marvos 4?
It limits the scope of any future quality action to the affected batch instead of the whole range.
How quickly can a repeat order be produced?
For established configurations production typically runs two to four weeks, with transit on top depending on the chosen method.
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
A short quarterly review of these points will keep the Marvos 4 range healthy without consuming the week.
