The "One-Day Tour in Bonded Zones" in the Comprehensive Bonded Zone is a part of the bonded logistics and is also referred to as "Immediate Export and Reimport" or "One-Day Tour." This business model involves the export of domestically produced goods to special customs supervision areas such as comprehensive bonded zones or bonded logistics centers (Type B). The exported goods are treated as if they have left the country, enabling processes such as export settlement, tax refund procedures, and handbook verification. The goods briefly stay within the zone, and downstream enterprises import the goods back from the comprehensive bonded zone, allowing for flexible choices such as bonded, duty-free, or taxed imports based on demand. Compared to the "Hong Kong One-Day Tour," the "One-Day Tour in Bonded Zones" not only simplifies export and import procedures but also saves significant transportation costs. Due to the short processing time, the entire operation, from goods export to zone entry, import clearance, and zone exit, can typically be completed within a day (even within a few hours). The "One-Day Tour in Bonded Zones" integrates and utilizes various policies in the comprehensive bonded zone, involving intensive operations in information flow, goods flow, and fund flow. It includes core processes such as customs declaration, payment settlement, and foreign exchange transactions. This innovative logistics model addresses the complexities associated with processing trade, complicated transfer procedures for deep processing, non-refundable value-added portions, and the requirement to export goods before re-importing according to foreign specifications. It is a highly integrated and valuable logistics solution.
