Guangxi Testliner Mills Offer Longer Validity as Coastal Converters Push Inland Dual-Sourcing
Inland testliner suppliers in Guangxi are extending offer validity to win dual-source programs from coastal carton plants hedging East China board tightness.
Testliner and recycled medium mills in Guangxi are quoting longer price validity—often 10–14 days versus shorter coastal spot windows—as East China converters look for backup tons into August.
Freight inland-to-port still decides landed cost, but buyers say the real win is construction continuity when coastal medium booking slots slip. Print-face grades remain harder to substitute without a new proof.
Why buyers care: a dual-source board plan fails if ECT and moisture targets are not locked before the first inland trial lot ships.
Buyer takeaways
Compare landed cost including inland trucking, not mill gate alone.
Freeze flute/construction and ECT before approving a second mill.
Ask whether August tons are contract-backed or opportunistic spot.
