Because our customers separate them even there is no such classification in the research. Barefoot Pellets is really huge, however, there is not available such a lot white pellets in the market. Even Categories A1 and A2 = Barefoot Pellets , the ONLY difference is the color ! Everyone should understand that. in some years tome come more and more clients understand that and there will be time when Categories A1 and A2 will be hard to get as it is with Barefoot Pellets . As market for pellets grows exponential the same is with demand.
