Carrier-Compliant Oversized Postal Shipping, Not a General Mailer
This box style is engineered around postal and parcel carrier dimensional and weight rules for oversized packages, helping shippers avoid dimensional-weight surcharges. It differs from a general big mailing box by prioritizing exact carrier-compliant outer dimensions over a locking-mailer format.
Popular Use Cases
- Heavy or bulky postal shipments: Items that fall into oversized postal rate tiers and need exact-fit dimensions.
- B2B parts and equipment shipping: Larger components shipped via postal or parcel carrier rather than freight.
- Bulk mail-order fulfillment: High-volume shippers standardizing on carrier-compliant box sizes.
Weight Ratings and Reinforcement
Single-wall 200# test suits lighter oversized loads, while 275# double-wall corrugated handles heavier postal shipments without corner crush. Reinforced corner and edge construction protects against damage during automated postal sorting equipment.
Sustainable, Eco-Friendly Packaging
A 2025 McKinsey & Company survey found over 60% of U.S. consumers pick green packaging when they have the choice. Crat Packaging offers recyclable and FSC-certified board options so you can meet that demand without paying a premium or waiting on long lead times.
