Non-Intrusive Inspection (NII) is a non-intrusive inspection method used by customs in the supervision of import and export goods. It uses X-rays, gamma rays, scanning imaging and other equipment to perform透视检查 on containers or goods, allowing customs to determine whether the goods match the declaration without opening the container. Use cases include: customs risk targeting, random spot checks, transit transportation supervision, etc., commonly seen at ports, airports, and bonded zones. Notes: NII does not damage cargo seals, but if the image is abnormal, customs may switch to manual unpacking inspection; enterprises should ensure accurate declaration information to avoid delays caused by blurred images or concealment. Compared with 'manual inspection', NII is more efficient and lower cost, but cannot fully replace manual physical inspection of sensitive goods; similar to 'X-ray scanning', but NII is the official term that emphasizes technical means. Foreign trade practitioners need to understand the extra time NII may cause and cooperate with customs by providing necessary documents.
📝 Examples
1. A batch of our exported electronic products was targeted by customs and required NII; fortunately the image was clear and they were released half an hour later. (This shows NII is efficient and can clear goods quickly under normal circumstances.)
2. Because NII found an abnormal image inside the container, customs decided to switch to manual unpacking inspection, causing the goods to be detained for two days. (This shows NII may escalate to manual inspection, so time should be reserved.)
