U.S. Customs Compliance Alert: AMZ123 Container Shipments Face Potential ISF Filing Risks Due to “2R” Codes

Recently, some cross-border logistics providers have reported an increase in U.S. Customs compliance issues related to AMZ123 shipments. Several containers were assigned “2R” status after arriving at U.S. ports, indicating potential problems identified during customs review. These cases have attracted attention among exporters and freight forwarders due to possible delays and additional costs.

According to industry sources, the “2R” code is mainly associated with issues related to Importer Security Filing (ISF) compliance. Common triggers include inaccurate importer information, inconsistent submission details, incorrect company addresses, and mismatched HTS codes. Such discrepancies may result in customs inspections, container holds, and extended clearance procedures.

Experts emphasize that accurate documentation and strict compliance management are essential for avoiding unnecessary risks in U.S. import operations. Importers and logistics providers should carefully verify ISF information before shipment departure, ensuring that all data matches commercial documents and customs requirements.

With increasing customs supervision in international trade, professional logistics management has become more important than ever. Companies engaged in China–U.S. shipping are advised to strengthen compliance procedures, improve communication with customs partners, and adopt reliable supply chain solutions to ensure stable and efficient cargo delivery.
