Implementation of the J4 Tipper Body Design Code

In July 2023, the National Heavy Vehicle Regulator (NHVR) released Vehicle Standards Bulletin 6 (VSB6) Version 3.2, which saw the implementation of the J4 Tipper Body Design Code.

To facilitate the implementation, the NHVR introduced a transitional period that provided modifiers with an option to use either the new J4 Code or the former J1 Code until 1 July 2024.

During this time, the NHVR worked with peak industry bodies to understand their concerns and ensure any barriers to adoption of the new J4 design code were addressed.

This review has now been completed with a new version of the J4 design code available and final transition arrangements being developed. The changes to the code do not relate to any technical requirements, but simply remove several “recommendations”.

The NHVR will be implementing the revised J4 design code in three stages:

• From 1 July 2024 - the revised J4 code will be published on the NHVR website, allowing AVEs and body builders to review the code and apply for J4 accreditation when applicable.
• From 1 October 2024 – a 6-month period will be provided to allow tipper manufacturers who have not already transitioned to a J4 design to start having their designs assessed by Approved Vehicle Examiners (AVEs) and J4 designs issued.
• From 1 April 2025 – all tipping body fitments certified under the J1 code must be completed to an approved J4 design.

This will be the final implementation phase of the J4 Tipper Body Design Code. There is no requirement to apply for an extension as the above dates will automatically apply to all AVEs.
