The Bickmore will be fine to use, @Deborah Long. Farnam and Su-Per Pine Tar are two other brands of pure pine tar that I've seen for sale in the US.
It always pays to read the labels, however. If it's not pure pine tar, you might also see ingredients such as "tall oil", turpentine, pitch, or rosin as ingredients in addition to the pine tar.
Auson (Sweden) sells pure pine tar as well as mixtures of pine tar and other ingredients. Dalbrand Tratjara (Dale Burned Wood Tar) #773 and Akta Tratjara (Genuine Wood Tar) #850 are both pure pine tars. I haven't seen the Dale Burned for sale in the US in the past year or so, but I just bought a can of their Akta Tratjara a month or so ago.
