Strategic Materials Stockpile

A strategic stockpile (in the United States, the Strategic Materials Stockpile, later the National Defense Stockpile) is a government-maintained reserve of raw materials considered essential to national security and defense production. The United States classified asbestos as a strategic material throughout much of the 20th century and stockpiled large quantities of chrysotile, amosite, and crocidolite for use in military shipbuilding, aerospace, and other defense applications. These stockpiles were managed under federal programs that purchased asbestos from foreign mines and stored it for wartime and emergency use.

Origin

The U.S. strategic stockpile program was formalized by the Strategic and Critical Materials Stock Piling Act of 1939, passed in anticipation of World War II. Asbestos was designated a strategic material because the U.S. had almost no domestic production and depended on imports from Canada, South Africa, and later Southern Africa and Russia. The program continued through the Cold War under the Defense National Stockpile Center.

Significance in Asbestos Context

The strategic stockpile designation matters to patients and families because it documents, at the highest levels of the federal government, that asbestos was known to be essential, tracked by type, and sourced from specific mines abroad. Stockpile records can help establish what fiber types (chrysotile, amosite, crocidolite) were flowing into U.S. industry during the years a patient was exposed, which supports provenance analysis and fiber-burden evidence in legal claims. For Navy veterans, shipyard workers, and defense-industry workers, stockpile and procurement records can corroborate that the specific products they handled contained the more dangerous amphibole fibers. The existence of the stockpile also undermines defense arguments that asbestos hazards were unknown: the same government stockpiling the material was, by the 1960s and 1970s, also regulating it as a health hazard.

Example Sentence

His lawyer requested federal stockpile procurement records to show that the amosite insulation used on his ship during the 1960s was sourced from South African mines tracked by the U.S. government.

Notes

• If you or a loved one worked in defense industries, shipyards, or served in the military, ask your legal team to request federal stockpile and procurement records through the General Services Administration and the Defense Logistics Agency.
• Preserve any military service records, MOS (Military Occupational Specialty) documentation, ship assignments, or base assignments. These connect personal exposure to specific federal supply chains.
• Stockpile records often identify fiber type and country of origin; this can be critical when a case turns on whether you were exposed to amphibole fibers (amosite, crocidolite), which are more strongly linked to mesothelioma than chrysotile.
• Ask whether your case includes a government-contractor defense issue. Defendants sometimes argue federal specifications shield them from liability, and stockpile evidence can be relevant to that dispute.
