First announced two years ago, Canada’s ban on octhilinone (OIT) as a material preservative in paint officially went into effect on May 31.

The ban forbids the manufacturing and selling of finishing paints containing OIT preservatives and extends to the prohibited purchase and import of paints with OIT properties that have been manufactured in the United States as well.

Ban’s Scope and Relationship to Canada’s Requirements

In addition to the ban on OIT product selling and manufacturing in Canada, Health Canada’s Pest Management Regulatory Agency (PMRA) has also created an allowable but condensed use rates for polymer compounds, aqueous emulsions, colorants and adhesives (0.54 a.i./L max).

First announced two years ago, Canada’s ban on octhilinone (OIT) as a material preservative in paint officially went into effect on May 31.

To confirm OIT preservative use in these materials, agency inspectors will have the right to question and request additional information from suppliers about individual components within its paint products.

According to the American Coatings Association, however, PMRA will allow for the sales of finished paint and coatings stocks containing OIT as a material preservative until they reach depletion, so long as the products were manufactured or imported into Canada prior to the ban going into effect.

The Canadian Paint and Coatings Association is also working with PMRA to clarify and confirm this allowance.

As for Canada’s Pest Control Products Act, the legislation requires that all antimicrobial preservatives be registered with PMRA. These articles will remain subject to regulatory oversight but do include exemptions for article registration. Traditionally, only the pesticide is required to be registered, however, if an antimicrobial preservative used to treat the article is already registered under the legislation, the article itself may also be exempt from registration.

Other exemptions from registration include when an article is treated according to the antimicrobial preservative’s approved uses and limited use in preventing degradation or damage to the product from organisms.

As for exemptions coming from the U.S., The Federal Insecticide, Fungicide and Rodenticide Act requires that all pesticides are registered within the U.S. Environmental Protection Agency prior to involvement with interstate commerce. The only exemption allowed by the U.S. Code of Federal Regulations is when an article is treated with or contains a pesticide that protects the article or itself, which includes pesticide-treated paints to protective coatings.

What’s Next

Although PMRA has stated that it will not be making any changes in final restrictions for the ban, ACA is continuing to monitor updates about Canada’s review process for OIT, including new restrictions and uses. According to ACA, the association keeps a good relationship with CPCA and other related trade organizations so that members can stay informed on PMRA continued activities.
