Frequently asked questions
Why does batch traceability matter for Meta 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.
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.
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.
