There's not really any such thing as "free trade". All purported "free trade" has conditions attached, whether you see them or not. A government's ability to enforce regulations on its companies (be it over consumer protection, safety, workers rights, standards compliance...) is undermined if companies from another country can "free trade" across the border while not themselves being beholden to any of those restrictions. Therefore any such "free trade" agreement has limits and usually involves some sort of harmonization of standards.
