CSA has the Marks you need to sell your products in the U.S.A. and Canada
You know about the integrity of our certification marks, our commitment to meeting your deadlines, and our testing expertise. But what you may not know is that, over the past decade, CSA International's role as a certification and testing organisation has grown.
Accredited in the U.S.
Since 1992, CSA International has been recognised as a Nationally Recognized Testing Laboratory (NRTL) by the U.S. Occupational Safety and Health Administration (OSHA). That means we test and certify your electrical, fuel burning and plumbing products to U.S. as well as Canadian standards. Your certification will be recognised many federal, state, provincial, and local authorities. For a complete listing of the products we certify, search our Certified Product Listings.
We know the North American market
Whether your products are exported to the U.S.A. or Canada, CSA can test and certify your products. We know the standards and codes that apply. CSA Marks are accepted on products you export to the U.S.A. and Canada.
