Corrugated Sheet Plants Ask Export Buyers to Separate ECT Holds from Artwork Freezes
Corrugated sheet suppliers want ECT/FCT locks booked earlier so print freezes do not outrun board reservations.
Corrugated sheet plants in Anhui say July export programs still freeze print and dielines while board remains on spot medium—raising last-minute construction swaps.
Sheet suppliers tell PackTrades buyers to reserve ECT/flute holds before artwork sign-off when August sailings are firm.
Why buyers care: a perfect print proof on a weaker board still fails stack tests at destination.
Buyer takeaways
Book board reservation and print freeze as two dated milestones.
Write ECT/FCT method and flute lock into the PO.
Use PackTrades Corrugated Board & Sheets filters to compare mills that state test methods.
