Bonded Testing

Bonded testing refers to the inspection, examination, testing, and related operations performed on imported goods within special customs supervision areas (such as bonded zones or comprehensive bonded zones) or bonded warehouses without the immediate payment of import duties and value-added tax. This term is commonly used in international trade when goods require quality inspection, technical testing, or repair-related examination. Enterprises can leverage bonded policies to defer tax payment and reduce capital occupation. Use cases include: imported equipment that needs to be debugged and tested under bonded status before deciding whether to sell domestically or re-export; or returned goods that need testing and repair. Notes: Testing activities must be conducted under customs supervision, and goods must not leave the designated area without authorization; the testing period is usually limited, and relevant procedures must be completed if it expires; if the goods are sold domestically after testing, taxes must be paid retroactively. Unlike 'bonded processing' and 'bonded warehousing,' bonded testing focuses on testing services rather than production processing or storage, and the condition of the goods may change after testing without substantial processing. Enterprises must apply to customs in advance and establish electronic ledgers to ensure compliance.
