of 100
Low exposure
Nothing in this registration suggests controlled work today. That is a statement about the record, not a clearance — a single subcontract can change it without changing any code.

This score is an indicator built from public industry and product codes. It is not a jurisdiction determination — only a commodity jurisdiction review of actual articles and technical data establishes what is USML-controlled. It is not a finding about this company's compliance program, and it is not legal advice.
