The Bureau of Industry and Security (BIS), in this temporary final rule (TFR), announces the criteria and process it will use to monitor existing companies for evidence of stockpiling, limit a newly established importer's ability to stockpile, and subject companies that are stockpiling to an import prohibition if necessary.
