Its moisture content of 19 percent or more makes it inexpensive, but it can move unpredictably as it shrinks and dries. You'll get less movement with kiln-dried (KD) or surface-dry (S-DRY) lumber, which has a moisture content between 16 and 19 percent. (KD-HT means the wood was also heat treated to kill pests, a requirement for imported lumber.)
