# Are Your Products Exported to the EU Always Detained at Customs? Senior Agency Solves Customs Clearance and Tax Refund Pain Points

## Current Status and Core Obstacles of Export to the EU Market

In the second quarter of 2026,the EU CBAM entered its third reporting cycle.Export enterprises in the chemical,steel,and aluminum product industries generally face delays in carbon emission data verification.Three containers shipped to the Port of Hamburg earlier this year by the Wuxi-based machinery manufacturer where Ms.Lin works were detained at the Port of Rotterdam for 17 full days due to missing CE certification technical documents,resulting in demurrage and storage losses of more than EUR 120,000.This situation is not an isolated case.Data from the European Commission Directorate-General for Taxation and Customs Union shows that the average customs clearance time for Chinese exported goods in 2025 was 2.3 working days longer than that in 2024,and the rejection rate of tax refund rate verification increased by 4.7 percentage points year-on-year.

The core crux is concentrated in three levels: First,the new version of the EU Market Surveillance Regulation requires importers to retain electronic product compliance files for at least 10 years,while most export enterprises still use the paper document transmission mode; Second,the CBAM declaration system is not fully connected with the customs systems of member states,and the matching failure rate between carbon emission data and customs declaration information is as high as 18%; Third,VAT refund applications must be submitted within 90 days after customs clearance of goods,but the random inspection rate of tax audits has increased to 35%,and the tax refund freezing period for enterprises due to non-compliant input invoices is as long as 6 months.

## Core Value of Zhongshen Export Agency Services

In response to the above barriers,Zhongshen completed the upgrade of its service architecture in the fourth quarter of 2025 and established a dedicated EU line operation team.The team consists of 12 customs brokers holding senior AEO certification qualifications,and directly connects with the customs systems of Germany,the Netherlands and Belgium.After Ms.Lin signed an agency agreement with Zhongshen in January 2026,the batch of mechanical equipment she shipped to Poland took only 11 days from factory loading to signing for receipt at the Warsaw warehouse,9 days shorter than the previous self-operation model,and zero detention was achieved in the customs clearance link.

The core value of the service is reflected in pre-risk control and parallel process processing.Zhongshen launches pre-screening of EU REACH regulations at the order acceptance stage,and intervenes in technical document preparation 90 days in advance for chemical products,electrical and electronic equipment and other products.At the same time,through the NRA account system filed with the Foreign Exchange Administration of Shanghai Pilot Free Trade Zone,it realizes synchronous operation of foreign exchange receipt and payment,foreign exchange settlement and purchase,and tax refund declaration,avoiding the time loss caused by serial waiting of each link in the traditional model.

## Document Processing Module: Accurate Matching of EU Compliance Documents

### Technical Document Pre-audit Mechanism

The EU’s mandatory DPP system in 2026 requires three categories of goods,namely machinery,batteries and textiles,to be embedded with QR codes linked to a cloud database containing carbon footprint,material composition and recycling instructions.After receiving Ms.Lin’s product drawings,the document department of Zhongshen completed the construction of the DPP data template within 48 hours,and coordinated with the Shanghai laboratory of SGS,a third-party testing institution,to obtain the DoC before the goods are shipped.

The risk point is that about 23% of export enterprises mistakenly regard CE certification as valid for life and ignore the random inspection of market supervision institutions of EU member states.In March 2026,French customs returned a batch of lamps produced by an enterprise in 2024 at one time,on the grounds that the EN standard on which the CE certification of this model was based was updated in 2025.Zhongshen’s response strategy is to establish a dynamic database of EU standards,synchronize the CEN-CENELEC standard update list weekly,and conduct annual compliance review of products of cooperative customers.

- First,intelligent selection of certificate of origin (RCEP and EU GSP): the system automatically matches the optimal tariff scheme according to HS Code and cargo value
- Second,data mirror verification of commercial invoices and packing lists: ensure zero difference in information among customs declaration form,bill of lading and insurance policy
- Third,pre-binding of CBAM carbon emission report and customs declaration form: complete data filling in the EU CBAM registered account before the goods leave the port

## Customs Clearance Service Module: AEO Certification Channel and Risk Interception

### Priority Channel Access Qualification

Zhongshen holds the senior AEO certification of China Customs,and enjoys mutual recognition convenience in EU member states.Since 2026,the customs of the Netherlands and Germany have implemented a policy of reducing the inspection rate by 60% for AEO enterprises.For the precision instruments Ms.Lin shipped to Dusseldorf in April,through the AEO pre-ruling application submitted by Zhongshen,the classification pre-review was completed 3 working days before the arrival of the goods,and the goods directly entered the green release channel after arrival,and the inspection probability dropped from the conventional 12% to 0.8%.

Specific EU policy barriers are reflected in anti-dumping investigations and environmental protection surcharges.In May 2026,the EU launched an anti-circumvention investigation on glass fiber products originating in China,involving a cargo value of about EUR 320 million.After receiving the early warning,Zhongshen’s risk control team launched a supply chain traceability restructuring plan for affected customers within 24 hours.By adjusting the raw material procurement place certificate and processing procedure records,the customers’ products were successfully excluded from the scope of the investigation.

| Customs Clearance Step | Average Duration of Self-Operation Model | Duration under Zhongshen Agency | Efficiency Improvement |
| --- | --- | --- | --- |
| HS Code Pre-Classification | 5 working days | 1 working day | 80% |
| Customs Declaration Form Audit | 2 working days | 0.5 working day | 75% |
| Customs Inspection | 3-7 working days | 0.5-1 working day | 83% |
| Overall Customs Clearance | 10-15 working days | 3-5 working days | 50-67% |

## Tax Refund Service Module: Acceleration of VAT and Export Tax Refund

### Closed-loop Management of Input Invoice Compliance

In 2026,the State Taxation Administration implemented the electronization of export tax refund filing documents,requiring enterprises to complete invoice certification and information upload within 15 working days after the customs declaration form is released.Zhongshen’s tax team established a supplier invoice whitelist for Ms.Lin,and conducts quarterly review of the invoicing qualifications of 113 upstream raw material manufacturers to ensure that the tax rate,product name and specification of input invoices 100% match the export customs declaration form.

The unique risk point in the EU market is that some member states require importers to provide VAT deferred clearance certificates.If export enterprises cannot provide them in time,the tax refund may be temporarily withheld.In February 2026,Spanish customs conducted a VAT deferred verification on a batch of equipment worth EUR 800,000 from an enterprise.Due to the lack of EORI number validity certificate,the tax refund cycle was forced to be extended by 4 months.Zhongshen’s response measure is to apply for the EU EORI number for customers synchronously before the goods are shipped,and mark the VAT deferred application number in the remarks column of the customs declaration form to ensure the integrity and traceability of the tax chain.

The key to improving the speed of tax refund lies in the parallel declaration mechanism.Under the traditional model,enterprises need to wait for the push of customs clearance information before starting the entry of the tax refund system,with an average delay of 5-7 working days.Zhongshen directly captures the release data of the Customs H2018 System through the API interface,and triggers the tax refund declaration process on the day the goods leave the port,shortening the tax refund arrival cycle from the industry average of 45 days to 12-15 working days.The total tax refund of CNY 2.17 million for Ms.Lin’s three export businesses in the first quarter of 2026 all arrived within 14 days.

## Coordination of Foreign Exchange Receipt and Payment and Foreign Exchange Settlement and Purchase

EU buyers generally adopt euro LC or collection (DP/DA) for settlement,and the average exchange rate fluctuation risk exposure is 30-45 days.Zhongshen’s foreign exchange team configured a combination of forward foreign exchange settlement and foreign exchange swap tools for Ms.Lin.Under the background of 1.8% fluctuation of the euro against the US dollar in 2026,the loss of the locked settlement exchange rate was controlled within 0.3%.Through the FTN account system of Shanghai Pilot Free Trade Zone,it realizes direct entry of euro payment,avoiding the secondary handling fee caused by the transfer of traditional offshore accounts,and saving about 0.15% of exchange cost per transaction.

Specific EU policies require importers to indicate the complete EORI number and transaction reference number when paying for goods.Zhongshen embeds this information into the 70 field remarks column of the SWIFT message during the document making stage to avoid the buyer’s bank refusing to pay due to missing information.In April 2026,a customer failed to mark the EORI number,and the German buyer’s bank initiated a compliance inquiry,and the payment was detained in the intermediary bank for 11 days.Zhongshen lifted the freeze within 48 hours by submitting a supplementary statement and transaction background certificate to ensure the normal collection of payment.

## Practical Case: Quantitative Improvement of Customs Clearance Efficiency and Tax Refund Speed

In March 2026,Ms.Lin exported a batch of CNC machine tools to the Czech Republic,with a cargo value of EUR 450,000 and HS Code 8458.91.Zhongshen’s operation timeline is as follows: received the order on March 5,completed DPP data upload and CBAM carbon emission report pre-filling on the same day; obtained the AEO pre-ruling receipt from Czech customs on March 7; the goods were shipped from Shanghai Port on March 10; the goods arrived at the Port of Hamburg on March 22,and completed the transit declaration on the same day; the goods arrived at the destination warehouse in the Czech Republic on March 24,taking a total of 19 days.Compared with similar equipment shipped by Ms.Lin to the same buyer under self-operation in 2025,the timeliness is increased by 42%,and the logistics cost is reduced by 18%.

For the tax refund link,after Zhongshen obtained the customs release information on March 25,it immediately launched the export tax refund declaration,and received the tax refund of CNY 364,000 on April 8,taking 14 working days.Previously,Ms.Lin operated through a local freight forwarder,and the average tax refund cycle was 38 working days,with a speed increase of 63%.

## Decision Path for Choosing Customized Agency Services

When evaluating the adaptability of agency services,export enterprises need to focus on three dimensions: whether the products are involved in EU environmental regulations (such as RoHS,WEEE,packaging directives),whether the annual export volume exceeds EUR 500,000,and whether the buyer requires DDP terms.If two of the three items are met,the marginal benefits generated by professional agency services will significantly cover the cost.

Zhongshen provides modular service combinations.Enterprises can choose the basic package of customs clearance + tax refund,or the full-process solution superimposed with foreign exchange management and warehousing and distribution.The digital compliance hosting service newly launched in 2026 is specially designed to deal with EU DPP and CBAM declaration,and is suitable for small and medium-sized enterprises entering the EU market for the first time.After three months of cooperation,Ms.Lin has transferred all the three routes of Germany,Poland and the Czech Republic to Zhongshen for agency,and the annual export plan has been increased from the original USD 3 million to USD 5 million,with controllable expansion risk.

At present,the EU market access threshold continues to rise,and the hidden expenditure of enterprises’ self-operation export model in compliance cost and time loss is often 3-5 times higher than the agency service fee.Zhongshen’s 20 years of accumulated EU customs data and policy response mechanism can minimize the trial and error cost of enterprises.For exporters planning to deeply cultivate the EU market,choosing an agency partner with AEO qualification,familiar with carbon tariff rules and with a digital document system is a key decision to ensure supply chain stability in 2026.
