Why can customized packaging machine projects lead to additional charges?
• Non-standard dies and formers omitted from the initial BOM often trigger extra charges when reordered later.
• If the contract does not lock the changeover spec range, bag width or film thickness changes are billed as design variations.
• Reusing standard PLC/HMI programs means custom interlock logic is rewritten and charged as extra engineering.
• Vague acceptance criteria let suppliers quote separately for post-FAT CE or FDA compliance modifications.
• Before signing, require a written list of custom parts and variation unit prices, with a cap on change orders.
