The International Ski Federation (FIS) has banned the use of fluorinated waxes in all of its disciplines from the start of the 2020-2021 season.
FIS Council member Roman Kumpost confirmed the change would come into effect at the beginning of the new campaign, but said a "measurement limit" of the substance will be defined to differentiate between "the use of fluorinated waxes and a potential contamination or an incomplete cleaning of the pre-existing material".
Athletes could be disqualified if flourine is detected in their wax.
The tolerance outlined by Kumpost will be reduced to the lowest possible level by the 2021-2022 season, with a view to removing the use of fluorinated wax completely before the 2022-2023 campaign.
The FIS has made the decision after the European Union (EU) banned certain fluorine compounds from July 1.
In a statement, the FIS said it had gone "one step further with its complete ban of all fluorine compounds".
"It has been shown they have a negative impact on both the health of people working with the wax and a harmful impact on the environment," Kumpost said.
"Regulations have been established in the United States that are already in place and will be implemented in the EU from July 2020 which impact the manufacturer of these products.
"The use of fluorinated waxes in all FIS disciplines is not allowed anymore and we will start to control the ban with the start of the upcoming season 2020-21.
"The tolerance mentioned above will be minimal and ensures a smooth transition for all stakeholders."
