Classified documents and material shall be destroyed by burning or, with the approval of the cognizant DoD Component head or designee, by melting, chemical decomposition, pulping, pulverizing, cross-cut shredding, or mutilation sufficient to preclude recognition or reconstruction of the classified information.
