Indonesia / United States Incident

Cesium-137 contamination traced from US port detections back to PT Metal Technology smelter in Banten. Orphan source entered via scrap metal. FDA halted shrimp imports. 22 companies contaminated. 1,500+ people monitored.

• CBP portal monitors detected Cs-137 at 68.5 Bq/kg — well below action threshold. System worked.
• Indonesia's "green lane" customs allowed contaminated scrap to bypass inspection. System failed.
• New mandate: all Indonesian smelters must install RPMs at facility gates as condition for import permits
• First FDA use of mandatory import certification authority

Confidence: 5/5. CBP, FDA, Indonesian Ministry statements. Documented regulatory response.
