This buyer guide helps you evaluate staged shipment and commissioning contracts for export machinery before committing capital to flexible packaging equipment. It focuses on scope, contract clarity, and acceptance discipline—not sales language.
Who this guide is for
Quality managers and project engineers defining FAT, SAT, and sign-off criteria with vendors.
Large flexible packaging lines rarely ship as a single event. Presses, dryers, unwind stands, and auxiliary modules may leave the factory on different dates because of run-off scheduling, crating capacity, or hall readiness at the buyer site. Without a staged shipment clause in the contract, disputes arise over who owns delay risk when one module arrives before foundations are poured or before SAT prerequisites are met.
Buyers should define shipment phases tied to measurable factory events—not calendar optimism. Phase one might include the print section and electrical cabinet after successful FAT; phase two covers turret unwind and inline corona after punch-list closure. Each phase should state crating standard, moisture protection for sea freight, insurance responsibility, and the documentation pack that travels with that serial number.
Key decisions before you sign
Commissioning scope must be separated from shipment scope in the same document. Vendor commissioning days quoted at PO often assume cleared hall access, qualified utilities, and customer-supplied web path materials on arrival. If site civil works slip, the contract should clarify whether standby rates apply, how many free days are included, and whether remote support substitutes for on-site presence during waiting periods.
Payment milestones should align with staged delivery rather than a single balance due on vessel departure. A common structure ties deposits to PO, progress payments to FAT readiness and successful witness tests, shipment releases to cleared punch lists, and final retention to SAT completion on agreed acceptance metrics. Buyers who release full balance before modules clear customs often lose leverage on open quality items.
FAT proves the machine at the factory; SAT proves it in your hall with your utilities and operators. Blending the two without written criteria invites argument.
Acceptance metrics should include register band, print density or coat weight, waste during ramp, and changeover time on agreed job families.
Buyer checklist
- Attach acceptance criteria to the purchase order or technical schedule.
- Define retest rules if FAT fails and who pays for re-witness.
- Record photos, torque sheets, and HMI recipe backups at sign-off.
- Separate FAT scope from SAT scope to avoid disputes after shipment.
Quotation, contract, and acceptance points
Site readiness checklists belong in the technical schedule attachment, not in informal email threads. Anchor bolt locations, floor level tolerance, exhaust routing, chill water flow rate, compressed air dew point, and minimum crane reach should be confirmed in writing before the vendor books freight. Yaoshg application teams typically review layout sketches during quotation so staged shipment plans reflect realistic rigging sequences.
Define who unloads, stores, and insures modules between port and hall. Staged shipments multiply handling events; each transfer is a damage risk unless crating inspection and photo records are contractually required. Buyers in humid climates should specify indoor storage with desiccant protocols if installation slips by more than a few weeks.
Acceptance criteria should state whether partial SAT on the first arrived module starts warranty clocks or whether warranty begins only after full line integration. Ambiguity here creates expensive arguments when a delayed laminator section arrives months after the press and the buyer expects full-line performance guarantees on day one.
Define who owns rework if FAT fails: part replacement, re-witness travel, and schedule impact. Clarity here prevents relationship damage later.
Common mistakes and how to avoid them
Signing FAT under pressure with open punch-list items often becomes permanent tolerance of defects. Document exceptions with dates and owners.
Yaoshg sales and application teams can review your substrate list, layout sketch, and quotation scope before you finalize internal approval. Sharing structured questions early typically shortens FAT scheduling and reduces open items at SAT.
