# Analysis of Practical Key Points of Customs Declaration Import for 2026 Export Tax Refund Declaration

## Customs Declaration Import for 2026 Export Tax Refund Declaration: Policy Changes and Implementation Guide

### I.Core Policy Adjustments of Customs Declaration Import in 2026

In 2026,the State Taxation Administration of China and the General Administration of Customs jointly optimized the policy for the customs declaration import link in export tax refund declaration,centering on two core directions: "data accuracy" and "efficiency improvement".The specific adjustments are as follows:

- **Upgrade of Electronic Data Verification Dimensions**: The original policy only verified the "existence" of electronic customs declaration data.In 2026,two mandatory rules are added: the first is "commodity code level matching",which requires that the first 6 digits of the commodity code on the customs declaration must be fully consistent with the enterprise’s customs-filed code (previously only required overall matching of the 10-digit code); the second is "consignee and consignor qualification correlation",which synchronously verifies whether the consignee and consignor’s customs registration qualification is valid.If either verification fails,the data cannot enter the tax refund declaration pool,and the enterprise needs to correct the data before retransmission.
- **Import Time Limit Compressed to T+1**: Before and including 2025,the import time limit was "within 3 working days after customs clearance",and it is optimized to "complete system synchronization within 1 working day from the date of customs clearance" in 2026.If the import is overdue,the enterprise needs to submit *Explanation on Overdue Customs Declaration Import* (affixed with official seal and explanation of reason) to the competent tax authority,and the import time after correction will be extended to 3 working days,which directly affects the tax refund progress.
- **Priority Import Channel for Key Commodities**: For the three categories of commodities included in the 2026 *Catalogue of Encouraged Export Commodities*,namely new energy vehicle parts,high-end medical devices and intelligent equipment,the customs declaration data will be automatically marked with a "priority" label during transmission.The import time is 40% shorter than that of ordinary commodities,and the fastest synchronization can be achieved "within 12 hours after customs clearance".

### II.Opportunities and Challenges of Policy Adjustment for Export Enterprises

According to the data of 320 foreign trade enterprises served by Zhongshen in Q1 2026,after the policy adjustment,enterprises’ tax refund efficiency and compliance risk have shown two-way changes:

- **Opportunity 1: Improved Capital Turnover Efficiency**: With the combination of T+1 import time limit and priority channel,the tax refund arrival cycle of new energy enterprises has been shortened from 12-15 working days in 2025 to 6-8 working days,and the capital occupation cost has been reduced by about 20%; automatic verification exposes data errors in advance,the number of corrections has dropped by 35% compared with 2025,and a single enterprise saves 2-3 man-days of labor cost per month.A Shanghai-based new energy parts enterprise processed 12 customs declarations through the priority channel in Q1 2026,the average tax refund arrival time was shortened by 6 working days,and the capital turnover efficiency increased by 28%.
- **Opportunity 2: Pre-positioned Compliance Risk**: The upgraded verification rule exposes data errors in the "import link" instead of being rejected in subsequent declaration,so enterprises can correct information in advance to avoid tax refund delay (the original average delay is 7 working days) or tax penalty (in 2025,some enterprises were fined 1% of the tax refund amount due to code errors).
- **Challenge 1: Sharply Increased Requirements for Data Consistency**: If the commodity code level and consignee/consignor qualification do not match the customs declaration,it will directly trigger import failure.In Q1 2026,the import failure rate of enterprises increased by 18% compared with 2025,of which 62% was caused by "mismatch of the first 6 digits of commodity code",and some enterprises made mistakes because the internal ledger did not synchronize the code level information.
- **Challenge 2: Increased Pressure on Time Control**: The T+1 time limit requires enterprises to pay attention to the import status in time.If there is no follow-up due to holidays or absence of special personnel,overdue correction will delay the tax refund for at least 5 working days.Among the micro,small and medium-sized enterprises served by Zhongshen in Q1 2026,22% had overdue import due to failure to monitor the import status,and 15% delayed the monthly tax refund declaration.

### III.How Zhongshen Helps Enterprises Solve Import Pain Points

In response to the new requirements for customs declaration import in 2026,General Manager Gong,head of the operation department of Zhongshen,led the team to launch three customized services,which accurately respond to the requirements with 20 years of industry experience:

- **Customs Declaration Pre-verification Service**: One working day before customs clearance,the team compares the commodity code level and consignee/consignor qualification of the enterprise’s customs declaration with the customs filing database and the tax refund system rules,and corrects errors in advance.In Q1 2026,the import pass rate of enterprises that used pre-verification reached more than 98%,12 percentage points higher than the industry average.In March 2026,a high-end medical device enterprise had a mismatch of the first 6 digits of the code,and Gong’s team found the problem in advance and assisted in correction,avoiding import failure.
- **Real-time Monitoring and Abnormal Early Warning**: We connect to the E-port of the General Administration of Customs and the tax refund system of the State Taxation Administration,establish a real-time monitoring system for import status,and synchronize customs clearance information to the exclusive WeChat Mini Program of the enterprise.If there is no import within T+1 or verification fails,the account manager will contact the enterprise within 1 hour to assist in preparing correction materials or situation explanation.In Q1 2026,the system issued 32 abnormal warnings,28 of which were solved within 12 hours,without affecting the tax refund declaration.
- **Priority Channel Docking Service**: For enterprises exporting encouraged commodities,we assist in sorting out commodity qualification certificates (such as new energy product certification,technical parameters of high-end equipment),and apply to the customs for marking the "priority" label in advance.In Q1 2026,the average import time of enterprises using the priority channel was shortened by 42%,and the fastest synchronization reached "T+0.5".

### IV.Practical Suggestions for Customs Declaration Import in 2026

Mr.Liang,policy advisor of Zhongshen,gave core suggestions based on policy changes: Enterprises need to check the import status through the agency platform or WeChat Mini Program within 24 hours after customs clearance of the customs declaration; if verification failure is found,prioritize checking whether "the first 6 digits of the commodity code are consistent with the customs filing" and "whether the consignee/consignor qualification is valid",so as to avoid declaration delay caused by basic information errors.If you are not sure whether the code level matches,you can contact the account manager of Zhongshen,and the team will provide code comparison service within 1 hour.

### Comparison Table of Customs Declaration Import Policies (2025-2026)

| Policy Point | 2025 Requirement | 2026 Requirement | Core Impact on Enterprises |
| --- | --- | --- | --- |
| Data Verification Dimension | Only verify data existence | Add code level matching and qualification correlation | Higher requirement for data consistency,errors exposed in advance |
| Import Time Limit | 3 working days after customs clearance | 1 working day after customs clearance | Time limit compressed by 50%,higher monitoring pressure |
| Priority Channel | No clear priority mechanism | Automatic priority marking for encouraged commodities | Import speed of key commodities increased by 40% |
| Overdue Handling | Correction allowed after submitting simple explanation | Detailed explanation required,import after correction extended to 3 working days | Higher overdue cost,increased delay risk |
| Import Failure Handling | Retransmit after correction (no time limit) | Need to requeue for import after correction (except priority channel) | Longer recovery time after failure |
