Scoring v1.3 · Methodology
64
of 100
Moderate exposure
These industry codes describe capability, not jurisdiction. A drawing package from a prime can put controlled technical data in this shop without changing a single registered code — which is the most common way an obligation goes unnoticed.

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.
