Bonded repair moves goods into a comprehensive bonded zone for repair and re-export with duties deferred. This guide covers the regulatory models, common categories, workflow and warehouse synergy in Shanghai.
Bonded Repair in China: How Comprehensive Bonded Zone Repair Models Work
Bonded repair is a high-value business model supported by policy in China's customs special supervision zones, such as comprehensive bonded zones. Goods in need of repair are moved into the zone, inspected, repaired and upgraded, then re-exported — with import duty and import-stage taxes deferred during the whole process, while warehousing and logistics operate in bond. In recent years, the State Council and the General Administration of Customs (GACC) have repeatedly issued policies supporting bonded repair in comprehensive bonded zones, with categories such as aircraft parts, medical devices and precision electronics gradually opened up through pilots. For importers, equipment manufacturers and repair service providers, understanding the regulatory logic of bonded repair and planning warehouse and ledger coordination in advance is the key to turning this policy into real savings (policy details are subject to official GACC and competent authority publications).
1. The Regulatory Logic and Three Common Models
The core of bonded repair is "repair operations under bonded supervision": goods inside the zone are not treated as entering the domestic market, taxes are deferred, and the account is closed after the repaired goods are re-exported. Compared with general-trade repair, it removes the import duty payment and export tax rebate steps, significantly reducing capital occupation and customs clearance costs. Three models are common in practice:
Model 1: Foreign goods enter the zone for repair and re-export. Overseas equipment and parts are shipped into the comprehensive bonded zone, repaired, and shipped back out. This is the most typical scenario, widely used for aircraft parts, marine equipment and medical devices.
Model 2: Domestic goods enter the zone for repair and re-export. Products made in China enter the zone for inspection and repair before being exported, which suits after-sales repair of export goods and is subject to customs requirements on repair scope and final destination.
Model 3: Repair on consignment within the zone. A company registered in the zone undertakes repair on behalf of domestic or overseas clients; goods move and are registered within the zone, and repair consumables are also managed under bonded supervision.
2. Which Goods Suit Bonded Repair? Common Categories
Not every product can be repaired in bond. Customs manages the scope of categories, processes and destinations, and the specific catalogue is subject to official announcements. Based on industry practice, the following are high-frequency categories:
| Category | Typical goods | Regulatory focus |
|---|---|---|
| Aircraft and parts | Engines, avionics, landing gear | Airworthiness, repair records, re-export reconciliation |
| Ships and marine equipment | Main engines, navigation instruments, pumps and valves | Port filing, repair cycle management |
| Medical devices | Imaging systems, endoscopes, rehabilitation equipment | Registration certificates, disinfection requirements, ledger matching |
| Precision electronics and semiconductors | Chip equipment, test instruments, panels | Anti-static storage, bonded consumables management |
| Industrial equipment and instruments | CNC machine tools, inspection meters, engineering equipment | Assembly and parts splitting, scrap handling |
3. The End-to-End Workflow and Warehouse Synergy
A complete bonded repair chain typically includes five stages: entry declaration, storage of goods awaiting repair, repair operations, re-export declaration and ledger reconciliation. First, goods are declared to customs under trade methods such as "goods for repair" and enter the zone with duties and taxes temporarily exempt; they are stored in the bonded warehouse. Second, goods awaiting repair are kept in separate zones by status, connected to the bonded warehouse's ledger management. Third, repair operations are carried out by the zone enterprise or through coordinated out-of-zone partners, with consumables drawn under bonded procedures. Fourth, repaired goods are re-exported with the corresponding exit declaration. Fifth, customs reconciles the ledger, and remaining parts, replaced parts and scrap are handled per regulations.
Warehouse synergy determines how efficiently bonded repair runs. Goods awaiting repair, finished goods and consumables need separated storage areas, and the ledger must match physical stock one-to-one — the same discipline as daily bonded warehouse management. Shanghai's bonded warehousing system, where Yunxiu operates, can provide storage for goods awaiting repair, temperature- and humidity-controlled space, and value-added operations such as Chinese-label affixing and kitting, helping repair companies close the loop of "storage + ledger + declaration" in one place.

4. Key Considerations When Setting Up Bonded Repair
First, confirm qualifications and market access. Bonded repair is normally carried out by companies registered in comprehensive bonded zones, and some categories require special filing or licenses; confirm applicability and declaration terms with the supervising customs office before starting. Second, strictly respect the repair scope. The objects, processes and destinations must comply with supervision requirements; out-of-scope operations may trigger duty recovery and penalties. Third, manage consumables and replaced parts properly: draw consumables in bond, and handle replaced parts and scrap through re-export, destruction or duty-paid domestic sale per regulations, with complete and traceable ledger records. Fourth, watch time limits and reconciliation. Storage and repair periods are subject to customs supervision; apply for extensions or change the goods' destination in time when needed (see the domestic-sale and re-export guides in the Related reading section below). Fifth, choose a partner with hands-on bonded warehousing experience, so that declaration, storage, ledger and value-added operations are managed as one package and trial-and-error costs stay low.
FAQ
Q1: What is the difference between bonded repair and ordinary repair? A: Ordinary repair usually requires importing goods under general trade and paying duty first. Bonded repair is carried out inside a comprehensive bonded zone under bonded supervision, with duties and taxes deferred during repair and reconciled after re-export — lower capital occupation and more flexible clearance.
Q2: Which companies can carry out bonded repair? A: Generally, companies registered in comprehensive bonded zones with repair capability can apply; some categories require additional qualifications, premises and ledger-management requirements. Specific entry conditions are subject to the regulations issued by the supervising customs office and competent authorities.
Q3: Do goods under bonded repair need to pay duty? A: Not during the repair period — the goods stay in bonded status with taxes deferred. If the repaired goods are not re-exported (for example, sold domestically), duties and import-stage taxes must be paid under the domestic-sale rules.
Q4: How are replaced parts and scrap handled? A: They must be disposed of per customs rules — typically re-export, destruction under supervision, or duty-paid domestic sale. Declaration and ledger records are required before disposal; unauthorized handling is not allowed.
Q5: Is Shanghai suitable for bonded repair? A: Yes. Shanghai has mature customs special supervision zones such as Waigaoqiao and Yangshan, plus a complete bonded warehousing system. The warehousing, logistics and brokerage resources are concentrated here, making it suitable for aircraft parts, medical devices and precision electronics.
