LLTM

Long Lead Time Material refers to items requiring extended procurement lead times due to manufacturing complexity, limited sources, or production capacity constraints. LLTM procurement must be initiated early to avoid schedule impacts on program delivery.

LLTM identification and management are critical for program planning and risk mitigation. Understanding LLTM requirements helps contractors plan procurement activities and manage supply chain risks. LLTM advance procurement authority may be needed for items with lead times exceeding normal contract timelines.
