Cross-Border Sellers Tighten Mailer Specs After Peak-Season Crush Claims Rise
Cross-border e-commerce sellers are rewriting corrugated mailer specs after a rise in crush and puncture claims on longer last-mile routes.
Cross-border sellers shipping beauty, accessories, and small electronics report more crush and puncture claims as parcels travel longer multi-hub routes into peak season.
Many are moving from lowest-cost B-flute mailers to constructions with clearer ECT, better glue-flap rules, and tear-strip specs that survive automated sortation—not only shelf photos.
Why buyers care: a mailer that passed a short domestic courier trial can fail on international sortation if board and seal strength were never specified.
Buyer takeaways
Put ECT, flute, and seal method on the mailer RFQ.
Trial packs on the real courier network, not only desk drops.
Cap print coverage where ink softens board performance.
