美国采购需求：信号干扰器、信号覆盖、通信天线、开放式 RRU、模拟中继器、射频连接器

I hope you're doing well. I'm currently evaluating the requirements for our upcoming order and wanted to clarify something important. Could you please confirm if the items we're interested in will require an NTC permit for manufacturing or shipping? Understanding this will help us in the procurement process and ensure compliance with all necessary regulations. Additionally, if there are any specific documentation or steps we need to follow to obtain this permit, please let me know. Having this information in advance will help us avoid any delays and ensure a smooth transaction. Thanks for your assistance!
