It looks like it is still up to the manufacturer if they use asbestos or not.
NAO (Non Asbestos Organic) are guaranteed to have No Asbestos, buy they wear quickly and have poor performance. I wont use them due to decreased braking performance, I think they are dangerous to use on a modern car.
You would have to contact other manufacturers to find out if they use asbestos in any particular pad you are interested in, I would not trust any parts store to know this.
"In 1989, the EPA proposed a ban on the manufacture, import, processing, and sale of asbestos-containing products to be phased out over seven years. But asbestos industry supporters challenged the ban in court.
The Fifth Circuit Court of Appeals upheld the first stage of the EPA ban -- which prohibited new uses of asbestos, **banned imported asbestos products, and ended the asbestos use in roofing and flooring felt, sheeting and tile, and clothing --
But overturned the second stage, which would have stopped asbestos use in products such as brake drum linings, automotive transmission components, gaskets, and other friction parts, as well as in the production and use of roof coatings, brake blocks, paper, pipe, and shingles made with asbestos.
A changing landscape: Asbestos in North America
Nevertheless, the automotive industry in the US recognizes the threat asbestos-containing brake part imports posed to auto mechanics’ health, and in 2010 California and Washington passed legislation that will require brake pads sold or installed in these states to have reduced levels of copper (no more than 5% by weight by January 1, 2021 in both states and no more than 0.5% copper by weight in California by January 1, 2025) and other heavy metals (no more than 0.1% by weight of asbestos, cadmium, chromium, lead, or mercury as of January 1, 2015).
On January 21, 2015, several automotive industry trade associations signed the Copper Free Brakes initiative, a voluntary Memorandum of Understanding with the EPA and the Environmental Council of the States, that extends standards adopted in California and Washington nationwide.
Like the US, auto manufacturers in Canada ceased the installation of asbestos-containing brake parts more than a decade ago, but in December 2016 the federal government in Canada announced a comprehensive ban on asbestos imports and use by 2018.
These initiatives have implications for the automotive brake parts aftermarket in North America, restraining future sales of low-cost imports from China and India, which are more likely to contain asbestos. Replacement brake part sales in the US and Canada will see a shift in the product mix toward alternatives such as NAO brake pads (which are less expensive, but also less durable, than asbestos-containing alternatives) and high-value, durable ceramic brake pads.
