I'v never ordered any batteries from FT. A while back FT had become unable to ship to Canada using E-Packet, a much faster more reliable shipping method for only a few dollars more. At the time the rumour was this service was denied to FT cause they were caught shipping batteries when they were not suppose to. It's just a rumour & I can't verify it.
I have always bought batteries from American vendors they come shipped as batteries & never had any problems at Customs.
I personally would never buy batteries from FT
