Is the standard for this codified in clear language anywhere, or is it merely based on the whims of some federal prosecutor/judge? If I make digital watches, and I buy coin cell batteries from a supplier who buys battery precursors from a supplier who buys LiCoO2 from a manufacturer who buys lithium-rich brine from a supplier who buys lithium mining equipment from a sanctioned entity, how much of the full brunt of Uncle Sam's retribution can I expect to come crashing down on me?
