Heavy-duty corrugated boxes are an increasingly popular alternative to wooden crates for export packaging of medium-weight goods. They offer significant weight savings (reducing freight costs), require no ISPM-15 treatment, and provide excellent protection when properly specified. This guide covers how to select and use heavy-duty corrugated boxes for international export successfully.

Advantages Over Wooden Boxes for Export

  • No ISPM-15 certification required – corrugated is exempt from phytosanitary regulations
  • 30-50% lighter than equivalent wooden packaging – major freight cost savings
  • Fully recyclable and biodegradable – meets sustainability requirements
  • Flat-packed for storage – takes minimal warehouse space until assembly
  • Custom printing for branding and handling instructions at no structural penalty
  • Faster to assemble and pack compared to wooden crating
  • When Heavy-Duty Corrugated Works for Export

    Corrugated boxes are suitable for export when the product weight is under 50 kg per box, the goods are not exposed to direct weather during transit (containerized), adequate internal cushioning and void-fill is used, and the boxes will not be subjected to fork-through handling. They excel in air freight where weight savings directly reduce costs, and in containerized sea freight where the container provides the primary weather protection.

    When to Choose Wood Instead

  • Products exceeding 50 kg per package
  • Open deck or break-bulk sea freight with weather exposure
  • Items requiring forklift handling directly on the package
  • Extremely fragile items needing rigid six-sided protection
  • Stacking loads exceeding the box edge crush rating
  • Specifications for Export-Grade Corrugated

  • Minimum 5-ply construction (7-ply recommended for items over 25 kg)
  • Bursting strength: Minimum 14 kg/cm² for sea freight
  • Edge crush test: Minimum 10 kN/m
  • Liner grade: High-performance kraft (minimum 200 GSM outer liner)
  • Moisture resistance: Wax coating or lamination for humidity protection
  • Closure: Industrial stapling or heavy-duty tape (not standard tape)
