Other unbleached kraft not meeting sack specs goes to 4804.51 if >150 g/m².
If mainly straw pulp with CMT resistance
Straw-based paper with mechanical/chemical pulp and crush test specs classify as straw fluting.
If made into sacks or bags
Once sewn or converted into actual sacks, it becomes a finished article of paper.
