The Irish Road Haulage Association says it will not take part in Friday's day of action.
A group representing lorry drivers says it's not participating in fuel protests on Friday.
However, the Irish Road Haulage Association says it won't actively discourage farmers or truck drivers from taking part in the planned demonstrations.
A day of action has been announced for Friday with convoys due to travel on major routes on Friday morning, including the M1, M3, M4, M7, N2 and N11.
In April, widespread protests organised by unofficial organisations, caused unprecedented disruption to roads, cities and fuel depots.
President of the Irish Road Haulage Association, and Rosenallis' Ger Hyland, says they won't be getting involved in demonstrations this week:
