Frequently asked questions
Why does batch traceability matter for Esco 4?

Yes, rolling agreements with defined review points work better for both sides than rigid annual commitments.
Can packaging be adjusted for our market?
Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.
