# Full Process Analysis and Key Node Control Guide for Xiamen Port EU Export Customs Declaration Agency

## New Challenges for Xiamen Port Exports Under the Changing EU Market

In the second quarter of 2026,the EU Carbon Border Adjustment Mechanism (CBAM) entered the second phase of the declaration period,and the electronic voucher system realized full interconnection with the customs clearance databases of member states.As the third largest hub port in terms of container throughput on the southeast coast of China,Xiamen Port transports about 42,000 TEUs of goods to the 27 EU countries every month,among which electromechanical products,textiles,and chemical products account for more than 67%.When sorting out recent cases,Director Hong found that more than 35% of returned orders are directly related to mismatched document data,especially HS code pre-classification errors and format defects of certificates of origin are the two high-frequency problems.The EU Commission’s updated Electronic Declaration Regulation for Import and Export Goods in March 2026 requires all non-EU enterprises to complete EORI number binding before declaration and submit additional environmental compliance declarations through the EU Single Window.This change has directly extended the average customs clearance time for Xiamen Port export enterprises from the previous 4.7 working days to 9.2 working days,and some first-time declaration enterprises even face the risk of port detention for more than 14 days.

## Core Value of Zhongshen Export Agency Services

Zhongshen has set up an independent operation center in Xiamen Port Free Trade Zone,equipped with 12 licensed customs brokers and 5 full-time document auditors,with an average working experience of more than 8 years for the team.Different from general freight forwarding companies,Zhongshen moves the service intervention node forward to the production link,and starts the document compliance review before the goods leave the factory.The team led by Director Hong has established a policy dynamic tracking database covering 15 major EU member states,updating the inspection focus and temporary tax rate adjustment information of customs of each country every week.From January to May 2026,among the Xiamen Port EU export business represented by Zhongshen,98.3% of the goods were released upon the first declaration,and the average tax refund arrival cycle was shortened to 11.6 working days,9.8 days faster than the industry average.This efficiency difference comes from the intelligent document pre-review system independently developed by Zhongshen,which has a built-in real-time synchronization module of the EU TARIC database and CBAM carbon content calculation model,which can identify potential declaration risk points within 30 seconds.

## Service Module Disassembly: Full Process Control from Documents to Tax Refund

### Document Preparation Module: Pre-audit to Avoid Compliance Risks

The EU customs’ requirements for documents present obvious "three modernization" characteristics: structured data,bilingual language,and complete proof chain.Taking textile exports as an example,the EU’s newly implemented Ecodesign for Sustainable Products Regulation in 2026 requires the provision of carbon footprint tracking documents from fiber procurement to finished product delivery,which must correspond one-to-one with the CN code on the customs declaration form.The operation specification of Director Hong’s team requires that in addition to providing basic documents such as commercial invoices,packing lists,and bills of lading,customers also need to submit product technical parameter sheets and basic supply chain carbon emission data 72 hours in advance.Zhongshen’s document auditors will check the matching degree between the invoice value and the customs valuation model one by one,check whether the exporter information on the certificate of origin is consistent with the EORI database filing,and verify whether the chemical export is accompanied by the SDS safety data sheet required by the REACH Regulation.For customers exporting to the EU for the first time,Zhongshen provides additional simulation declaration services,and verifies the validity of the document combination in advance through the test environment of the EU customs,which can reduce the error rate in formal declaration by 82%.

### Customs Clearance Operation Module: Digital Collaboration to Improve Release Efficiency

In 2026,the EU Digital Customs System (EU-DCS 2.0) was deployed in seven major hubs including Rotterdam Port in the Netherlands and Hamburg Port in Germany,realizing automatic capture and risk rating of pre-declaration data 48 hours before the arrival of goods.Zhongshen has realized API interface docking with this system,and the customs declaration data is synchronized to the EU customs database at the same time when the goods are loaded at Xiamen Port.Director Hong especially emphasized that the declaration window for CBAM certificates is only 72 hours after the goods are loaded and before arrival,and missing this time node will face a fine of 78 euros per ton of carbon dioxide emissions.Zhongshen’s operation process requires that when the goods pass through the Xiamen Port gate,the CBAM carbon content calculation program is triggered,and the system automatically matches the EU carbon emission factor database according to the weight,material,and production process of the goods,and generates an electronic certificate that meets the requirements of CN/HS codes.For electromechanical products,additional WEEE (Waste Electrical and Electronic Equipment) compliance certificates are required,and Zhongshen will coordinate with authorized representatives in the EU in advance to complete the registration number filing to ensure that all digital vouchers are activated when the goods arrive at the port.A typical case in April 2026 showed that a batch of photovoltaic modules worth 2.3 million euros realized immediate release upon arrival at Rotterdam Port in the Netherlands through pre-digital customs clearance operations,and the overall customs clearance time was reduced to 1.8 working days.

### Tax Refund Service Module: Data Closed Loop to Accelerate Capital Return

The speed difference of export tax refund mainly depends on two links: the letter adjustment efficiency of the tax authority and the matching accuracy of foreign exchange verification.In 2026,the State Administration of Foreign Exchange upgraded the foreign exchange monitoring system for trade in goods,requiring that customs declaration forms,value-added tax invoices,and foreign exchange receipts must be automatically reconciled on the Electronic Port platform,and any data deviation will trigger a manual review process.Director Hong’s team has established a "customs declaration-tax refund" linked ledger,completes the confirmation of the electronic information of the customs declaration form within 2 hours after the customs release of Xiamen Port,and simultaneously starts the cross-comparison of value-added tax invoices.Zhongshen has cooperated with a number of banks to open a tax refund pledge financing channel.For customers with Class A enterprise qualification,they can get 80% of the tax advance within 48 hours after submitting the tax refund application.In view of the unique situation of the EU market,Zhongshen has also developed an exchange rate locking tool,allowing customers to choose a fixed exchange rate for tax refund calculation when the goods leave the port,so as to avoid losses caused by fluctuations in the euro exchange rate.Data from the first quarter of 2026 showed that for Xiamen Port EU export business represented by Zhongshen,the average tax refund arrival time was 11.6 working days,with the fastest record of 6 working days,which was 58% faster than that handled by enterprises themselves.

## Efficiency Improvement: Dual Optimization of Time Cost and Capital Cost

To intuitively show the service difference,Director Hong provided the comparison data of similar Xiamen Port EU export business from January to May 2026.Enterprises that handle it independently need to connect with 4.2 government departments on average,submit 17 paper materials,and experience 3.6 return order modifications,with an overall cycle of 23.4 working days.While customers represented by Zhongshen only need to provide 5 basic electronic documents,the number of return order modifications is reduced to 0.3,and the overall cycle is compressed to 7.8 working days.In terms of capital cost,additional expenses such as port detention fees and document modification fees have dropped from an average of 1,240 yuan per shipment to 210 yuan,and the annualized return of working capital released by the early arrival of tax refunds is about 1.2% of the cargo value.

| Comparison Item | Handled by Enterprises Independently | Handled by Zhongshen | Efficiency Improvement Rate |
| --- | --- | --- | --- |
| Average Customs Clearance Time | 9.2 working days | 2.1 working days | 77.2% |
| Number of Returned Order Modifications | 3.6 times | 0.3 times | 91.7% |
| Tax Refund Arrival Cycle | 21.4 working days | 11.6 working days | 45.8% |
| Additional Expenses | 1,240 RMB/shipment | 210 RMB/shipment | 83.1% |
| Compliance Risk Rate | 12.3% | 1.7% | 86.2% |

## Decision Logic for Choosing Customized Agency Services

Different products face significantly different regulatory focuses when exporting from Xiamen Port to the EU.Chemical products need to focus on responding to the update of the SVHC list of the REACH Regulation,textiles need to pay attention to the carbon label requirements of the Sustainable Products Regulation,and electromechanical products need to meet the carbon footprint disclosure standards of the New Battery Regulation.Director Hong suggested that enterprises should match Zhongshen’s policy risk database according to the first four digits of the HS code of their products to identify highly sensitive regulatory items.For medium and large enterprises with annual export value of more than 5 million euros,Zhongshen provides on-site services,and sets up a liaison office within the customer’s enterprise to realize real-time synchronization of document generation and review.For small and medium-sized enterprises,a modular procurement model is recommended,and they can choose basic customs declaration,value-added customs clearance or full-chain agency services according to their needs,avoiding one-time payment of high fees.The EU policy environment is still evolving in 2026,and the Market Supervision Regulation that will take effect in June will introduce a product digital passport system,which means that export enterprises must complete the cloud upload of product full life cycle data before loading at Xiamen Port.Zhongshen has already laid out in advance and completed technical docking with three EU-designated digital passport platforms.Customers only need to provide basic product information,and the system can automatically generate digital identity documents that meet EU standards.Choosing a professional customs declaration agent is no longer a simple cost consideration,but a strategic investment in trade compliance certainty and market response speed.
