Electronic write-off dashboard showing data matching between import and export declarations with approval status

The General Administration of Customs of China (GAC) has issued new verification and write-off guidelines for processing trade, effective October 1, 2026. The most significant change: electronic reconciliation is now mandatory for all processing trade write-off applications. Paper-based reconciliation – where companies submitted physical documents (import/export declarations, production records, inventory reports) – is no longer accepted. All write-off applications must use electronic data matching between customs systems and the company‘s ERP or accounting software. For processing trade operators, this shift requires upgraded data systems, accurate record‑keeping, and real‑time data synchronization. This guide explains the new guidelines, electronic reconciliation process, and practical steps for compliance.

1. Key Changes – Mandatory Electronic Reconciliation

The 2026 verification and write-off guidelines eliminate paper-based reconciliation entirely. Key changes:

  • No paper submissions: Companies cannot submit physical write-off applications or supporting documents (import declarations, export declarations, production logs). All data must be submitted electronically.
  • Data matching required: Customs systems automatically match import raw material data with export finished goods data, production consumption rates, and inventory records. The company‘s ERP must be capable of exporting data in GAC‘s specified format (XML or JSON).
  • Real-time or batch synchronization: Companies can synchronize data in real time (via API) or in daily/weekly batches. Batch updates must be completed within 5 days of the transaction date.
  • Auto‑calculation of discrepancies: The system automatically calculates any discrepancy between expected and actual consumption (material usage, waste, inventory). Discrepancies exceeding 5% trigger a manual review.
  • Reduced write-off processing time: Standard write-off applications are processed in 5‑7 working days (down from 15‑20 days). Expedited processing (3‑5 working days) is available for Advanced AEO companies.
  • Retention period extended: Electronic records must be retained for 10 years (previously 5 years).

The new guidelines apply to all processing trade types: processing with imported materials (进料加工), processing with supplied materials (来料加工), and bonded assembly (保税装配).

⚡ Time saved: Write-off processing time reduced from 15‑20 days to 5‑7 days – up to 70% faster.

2. Electronic Reconciliation Process – Step by Step

The electronic write-off process consists of five steps, all conducted through GAC‘s processing trade platform (https://ptrade.customs.gov.cn):

  1. Data preparation (Ongoing): The company‘s ERP must capture and store: import raw material declarations (HS code, quantity, value), production consumption records (material usage per finished unit), export finished goods declarations (HS code, quantity, value), waste disposal records (re‑export, destruction, or duty-paid sale), and inventory counts (monthly or quarterly).
  2. Data transmission (Weekly or real-time): Companies transmit data to GAC via API or batch upload. The system validates data format and completeness automatically.
  3. Auto‑reconciliation: GAC‘s system compares declared import quantities against expected consumption (based on yield rates) and actual export quantities. Discrepancies are calculated automatically.
  4. Review and adjustment (if discrepancies): If discrepancies exceed 5%, the system flags the application. The company must submit an explanation (e.g., production loss, quality rejects, samples) and supporting electronic evidence (e.g., waste disposal certificates).
  5. Approval and write-off: After reconciliation, the system issues an electronic write-off confirmation. The processing trade handbook is automatically closed.

For companies without ERP integration, GAC provides an online data entry portal (for low‑volume processors, <10 transactions/month).

3. Data Requirements – What to Capture and Transmit

Companies must capture and transmit the following data elements in electronic format:

  • Import raw material data: HS code, product description, quantity, unit of measure, declared value, import declaration number, date of import.
  • Production consumption records: Yield rate (material consumption per finished unit), batch number, production date, scrap quantity, rework quantity.
  • Export finished goods data: HS code, product description, quantity, unit of measure, declared value, export declaration number, date of export.
  • Waste disposal records: Type of waste, quantity, disposal method (re‑export, destruction, duty-paid sale), certificate number (e.g., destruction certificate).
  • Inventory records: Opening inventory, closing inventory, and any adjustments (e.g., samples, damaged goods).

All data must be traceable to original source documents (retained electronically for 10 years).

📁 Record retention: Electronic records must be retained for 10 years. Customs may audit records up to 5 years after write-off.

4. Common Discrepancies and How to Avoid Them

Based on pilot program data, the most common discrepancies triggering manual review are:

  • Yield rate deviation (45% of discrepancies): Actual material consumption per finished unit differs from declared yield rate by >5%. Solution: Update yield rates quarterly based on actual production data. Submit justification for any significant changes.
  • Missing waste disposal records (25%): Waste quantities not accounted for (e.g., no destruction certificate). Solution: Implement waste tracking system. For waste destroyed in China, obtain destruction certificates from licensed facilities.
  • Inventory discrepancies (20%): Physical inventory count does not match system records. Solution: Conduct monthly cycle counts. Investigate and document any discrepancies.
  • Data transmission errors (10%): Missing fields, incorrect HS codes, or inconsistent units of measure. Solution: Use API integration to reduce manual entry errors. Validate data before transmission.

For discrepancies >5%, the write-off application will be delayed by 10‑20 working days while the company provides explanations and evidence.

5. ERP Integration – Recommended for High‑Volume Processors

For processing trade operators with 50+ transactions monthly, ERP integration is strongly recommended. GAC provides API specifications for direct data transmission. Benefits of ERP integration:

  • Real‑time data synchronization: Automatic transmission of import, production, export, and inventory data – no manual entry.
  • Reduced error rates: API integration eliminates manual entry errors, reducing discrepancy rates from 15% to under 2%.
  • Faster write-off processing: Real‑time data enables immediate reconciliation; write-off approved in 3‑5 days for Advanced AEO companies.
  • Automated discrepancy alerts: ERP can flag potential discrepancies before data is transmitted, allowing proactive correction.

ERP integration requires an IT team familiar with GAC‘s API specifications (available on the processing trade portal). For companies without in‑house IT, third‑party software providers offer pre‑built connectors.

🔌 API support: GAC provides API documentation, test environment, and technical support for ERP integration. Integration typically takes 2‑4 weeks.

6. Compliance Timeline and Penalties for Non‑Compliance

Implementation timeline:

  • October 1, 2026: Mandatory electronic reconciliation takes effect. Paper‑based write-off applications no longer accepted.
  • December 31, 2026: Final deadline for processing trade handbooks opened before October 1 to transition to electronic reconciliation. Handbooks not transitioned by this date will be suspended.
  • Ongoing: Companies must maintain electronic records for 10 years.

Penalties for non‑compliance:

  • Paper submission attempted: Application rejected. Company must resubmit electronically.
  • Incomplete electronic data: Application returned for correction. Processing delayed by 10‑20 working days.
  • Repeated data errors (>3 errors in 12 months): Fine of RMB 10,000‑50,000. Company may be required to submit a corrective action plan.
  • Intentional falsification of electronic data: Criminal liability under Customs Law (up to 7 years imprisonment).

Companies that fail to transition to electronic reconciliation by December 31, 2026, risk suspension of processing trade privileges.

7. Practical Compliance Roadmap for Processing Trade Operators

To comply with the new electronic reconciliation guidelines, follow this six‑step roadmap:

  1. Assess your current data systems (Immediate). Determine if your ERP can export data in GAC‘s required format (XML/JSON). For low‑volume processors, the online portal may suffice.
  2. Implement data capture for all required fields (Month 1). Ensure your system tracks import raw materials, production consumption, export finished goods, waste disposal, and inventory.
  3. Update yield rates (Month 1). Review and update yield rates for all products based on actual production data from the past 12 months.
  4. Set up data transmission (ERP integration or batch upload) (Month 2). For high‑volume processors, integrate ERP via API. For low‑volume processors, use the online data entry portal.
  5. Run a test write-off application (Month 2). Before your handbook expires, submit a test application to identify any data gaps or discrepancies.
  6. Transition all active handbooks to electronic reconciliation (By December 31, 2026). Submit electronic write-off applications for all handbooks opened before October 1.
