if the grading kit you have does not say light amber, medium amber, dark amber, and grade B it is not legal to use in NH this year. Unforunatly no more of these temporary grading kits are being made this year. There are some 2013 kits available but are getting harder to find. Maybe some of those Vermont sugarmakers would sell their used 2013 kits to us in need on the East side of the river.
