Why is the technical annex important in an export contract for a packaging machine?

• The annex fixes model, capacity and film-width range as the sole acceptance basis, not just 'pillow packer'.
• List PLC/HMI brands, servo axis count and CE/FDA certificates to prevent downgraded parts on arrival.
• Define FAT items and pass criteria (cycle time, seal strength, yield) tied to final payment.
• Specify spare parts list, MOQ, lead time and warranty to avoid downtime without replaceable parts.
• State changeover time, utilities and crating standards to cut customs and installation disputes.
