Case contract

dims inches (each rounded half up to a whole inch), actual lb rounded up (minimum 1). Dim weight = ceil(L*W*H/divisor) using rounded dims, only when the rounded cube exceeds 1728 cubic inches. Return [billable, "DIM"] if dim weight strictly exceeds rounded actual, else [actual, "ACTUAL"].

Why this case matters

Carriers bill the greater of actual and dimensional weight before zone rating.
