Sentinel Strategic Materials is a U.S.-based importer and supplier of ammonium perrhenate (APR), which is essential for domestic rhenium metal production and various industrial catalyst applications.
We prioritize origin-controlled sourcing, regulatory-compliant importation, and lot-level traceability, ensuring that our customers receive reliable, high-integrity chemical feedstock. Our role as a U.S. importer is to provide a compliance layer between upstream producers and downstream industrial or institutional users.
We act as Importer of Record, coordinating customs clearance, documentation, and quality assurance to guarantee consistent execution. Sentinel Strategic Materials exclusively serves industrial and institutional customers, and we do not sell laboratory reagents or retail quantities.
