Why serial number traceability matters on the Box 4
Batch identifiers should appear on the unit, the inner tray and the master carton.
The most common mistake is optimising for the first order instead of the fourth, which is where Box 4 economics actually settle.
A simple spreadsheet linking batch to destination account is usually sufficient at this scale.

Frequently asked questions
Why does batch traceability matter for Box 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
