CTU Code IMO/ILO/UNECE Code of Practice for Packing of Cargo Transport Units

The international code of practice for packing and securing cargo in containers and other cargo transport units: planning, load distribution, blocking, bracing, lashing and documentation.

CodeCTU CodeIssued byIMO / ILO / UNECEFieldPacking & securing

What it covers

  • Responsibilities in the supply chain, CTU suitability checks, packing and securing principles, accelerations to design for, documentation.

Key points for fabricators

  • Distribute the load evenly and keep the centre of gravity near the middle.
  • Block or lash cargo so it cannot move; fill voids.

How PEB Studio supports it

The loading planner checks payload, door and roof clearance and centre of gravity; securing is recorded in the container packing report. The plan is a planning aid, not a lashing certificate.
