# How Taizhou Enterprises Can Solve These Customs Declaration Difficulties When Exporting to the EU Market

## Market Status and Operation Difficulties of Taizhou Pharmaceutical Intermediates Exported to the EU

In the first quarter of 2026,the value of pharmaceutical intermediates exported from Taizhou to the EU increased by 14.7% year on year,while the return rate and port detention fees also rose simultaneously.When handling a shipment of antiviral drug intermediates worth around 500,000 euros exported to Germany,Ms.Deng encountered two new restricted substance testing requirements added to Appendix XVII of the latest revised REACH Regulation,which delayed the scheduled sailing date by 11 days and incurred nearly 20,000 yuan in additional storage costs.Such cases are not rare among Taizhou export enterprises.The second phase of the ICS2 system launched by EU customs in 2026 requires submission of complete cargo information 24 hours before loading,including HS code pre-classification,EORI number validity verification,and explanation of applicability of the rules of origin accumulation.Many Taizhou enterprises have not configured EDI declaration interfaces in advance,leading to the probability of their cargo being locked for inspection at the Port of Rotterdam rising from 8.3% in 2025 to 17.6% in 2026.

What is more complicated is that EU member states have different classification and definition standards for pharmaceutical intermediates.The same batch of carbohydrate derivatives may be classified as ordinary chemicals by Dutch customs,while French customs will classify them as pharmaceutical raw materials for supervision according to their end use,applying different import license and VAT treatment methods.Such uncertainty in policy implementation makes it difficult for Taizhou export enterprises to accurately calculate costs at the quotation stage,and they often face additional tax recovery or compliance fines after delivery.

## Modular Response Mechanism of Zhongshen Export Agency Services

In response to the above pain points,Zhongshen splits the whole process of exporting Taizhou enterprises’ products to the EU into three parallel operable modules: document pre-processing,customs clearance rehearsal,and tax refund acceleration.The team led by Ms.Deng no longer adopts the traditional linear mode of "preparing only after receiving orders",but intervenes in clause review as soon as the client signs the export contract.In March 2026,a biotech company in Taizhou entrusted Zhongshen to export a batch of enzyme preparations worth 1.2 million euros to Italy.Within 48 hours of receiving the draft contract,Zhongshen completed the compliance review of 16 items of the SDS under the EU CLP Regulation,found that the expression of acute toxicity data did not meet the latest EU format requirements,and initiated supplementary testing by a third-party laboratory in advance,avoiding the risk of cargo being detained due to inconsistent documents after arrival at the port.

The core of this pre-intervention mode is to convert changes in EU trade policies into executable operation lists.Zhongshen has established a dynamically updated policy database covering real-time supervision updates of customs of 27 EU member states.When the customs of a certain country releases new inspection priorities or tax rate adjustments,the system will automatically match the list of affected Taizhou clients and push customized adjustment plans.During the anti-dumping investigation on specific organic compounds originating in China launched by the EU in 2026,Zhongshen completed the third-country entrepot trade route design for 7 Taizhou clients in advance to ensure normal delivery of goods.

## Document Preparation Module: Accurate Disassembly of EU Access Thresholds

### Pre-audit Mechanism for REACH Regulation Compliance Certificate

The EU REACH Regulation strengthened the "one substance,one registration" principle in 2026,requiring substances with an export volume of more than 1 ton per year to complete formal registration.Most pharmaceutical intermediates exported by Taizhou enterprises are mixtures or polymers,so how to determine the subject of registration obligation has become the primary problem.Zhongshen’s operation logic is: first,determine the tonnage distribution of each substance in the product through chemical structure analysis and component quantitative analysis; then,judge which substances are eligible for polymer exemption and which need authorization from the lead registrant according to the latest guidelines issued by ECHA.

When handling the export of fluorine-containing compounds for a Taizhou enterprise,Ms.Deng found that although an impurity in the product only accounts for 0.3% of the content,the impurity itself is included in the SVHC list.According to the 2026 new regulations,as long as the impurity has functional purposes and the total volume exceeds 1 ton per year,independent registration is also required.Zhongshen urgently coordinated with the OR in the EU,completed the pre-registration of the impurity before shipment and obtained the registration number.If this detail is ignored,the cargo may be directly returned after arrival at the port,with losses reaching more than 60% of the total cargo value.

- Core document list includes: REACH registration number or pre-registration number,SDS (compliant with 16-item format of EU2020/878 regulation),CLP classification label,and authorization letter from the EU OR.
- Zhongshen’s pre-audit system will automatically compare with the ECHA database to verify the validity of registration numbers,eliminating the use of invalid or revoked numbers.
- For products requiring EU CE certification,Zhongshen will intervene 6 months in advance,coordinate with NB notified bodies to complete technical document review and factory audit,avoiding conflicts between certification cycle and delivery date.

### Rules of Origin and Preferential Tariff Utilization Optimization

The EU GSP removed tariff preferences for some chemical products originating in China in 2026,but the rules of origin under bilateral free trade agreements such as China-Thailand and China-Cambodia agreements still allow zero tariff treatment.The solution designed by Zhongshen for Taizhou enterprises is: for products containing imported components,apply the RCEP accumulation rule,take Thailand or Cambodia as raw material processing locations,obtain ASEAN FORM E certificate of origin,and enjoy further reduction on the basis of MFN tariff rate when exporting to the EU.In cases handled by Ms.Deng,by adjusting the supply chain route,the tariff for a batch of pharmaceutical intermediates produced in Taizhou was reduced from 6.5% to 2.1% during EU customs clearance,saving nearly 54,000 euros in tariff costs per shipment.

## Customs Clearance Process Module: Technical Docking with EU Customs Systems

### Time Limit Control for ICS2 System Phase II Declaration

The EU ICS2 system requires carriers to submit complete ENS declaration data 24 hours before loading in 2026,including 6-digit HS code,detailed consignor,consignee and notify party information,and accurate cargo description.The traditional operation habit of Taizhou enterprises is to prepare customs declaration materials only 1-2 days before sailing,which can no longer meet the new requirements.Zhongshen’s response is: after the client’s production plan is confirmed,start the "virtual declaration" process,use estimated data to submit simulation declarations in the system in advance,obtain feedback error codes and make corrections.

Ms.Deng’s team has developed a direct docking channel with EDI interfaces of shipping companies such as Maersk and Hapag-Lloyd.After the bill of lading draft is confirmed,the cargo information of Taizhou clients is automatically transmitted to Zhongshen’s pre-declaration platform to complete data verification and risk screening.The system has a built-in list of prohibited imported goods and high-risk goods marking library of customs of 27 EU countries.Once the cargo description triggers keywords,it will immediately issue an early warning and start manual verification.In April 2026,the system intercepted a shipment that misdescribed "nitrocellulose" as "cellulose derivative",avoiding huge fines for concealing dangerous goods identified by customs at the Port of Hamburg.

### Correlation Between AEO Certification Qualification and Lower Inspection Rate

EU customs grant an average 45% inspection rate reduction for enterprises holding AEO qualification.Zhongshen itself holds the Advanced Certification qualification of China Customs,and has established agency cooperation relationships with multiple AEO enterprises in the EU.Taizhou enterprises exporting through Zhongshen can "borrow" the AEO qualification of its partners for declaration and enjoy green channel treatment.According to data provided by Ms.Deng,the average inspection rate of Taizhou cargo operated through this mode at the Port of Rotterdam dropped to 3.2% in 2026,while the inspection rate of similar cargo not using this mode was 19.7%.

| Customs Clearance Node | Standard Operation Timeframe | Optimized Timeframe by Zhongshen | Risk Control Measures |
| --- | --- | --- | --- |
| ENS Declaration Submission | 12-24 hours before shipment | 48-72 hours before shipment | Pre-declaration + manual review,error rate reduced to below 0.3% |
| EU Customs Release | 24-48 hours after arrival | 6-12 hours after arrival | AEO qualification channel + pre-payment of taxes |
| Abnormal Inspection Handling | 3-7 working days | 1-2 working days | On-site intervention by cooperative customs brokers in the EU |

## Tax Refund Operation Module: Strategy to Shorten Capital Return Cycle

### Pre-audit Mechanism for Export Tax Refund Declaration Materials

The State Taxation Administration adjusted the classified management of export tax refunds in 2026,shortening the tax refund time limit for Class I enterprises to 5 working days,but requiring the completeness and accuracy of declaration materials to reach more than 99%.Taizhou enterprises are often downgraded to Class II or Class III enterprises due to problems such as delayed VAT invoice certification,minor differences between customs declaration data and invoice data,and non-standard foreign exchange receipt vouchers,extending the tax refund cycle to 15-30 working days.Zhongshen’s operation breakthrough lies in: advancing the tax refund declaration work to before the release of the customs declaration form.

Ms.Deng’s team completes the automatic comparison between customs declaration data and VAT invoices within 24 hours after the cargo is loaded,and verifies 12 key fields such as product name,specification,quantity,measurement unit,and amount one by one.If differences are found,the correction procedure is started immediately,rather than waiting until the tax refund declaration to deal with them.In May 2026,the customs declaration for a batch of goods exported to the EU by a Taizhou enterprise incorrectly filled the "unit" column as "kilogram" while the invoice used "kg".The system issued an early warning and the information was modified in time,avoiding a 10-day delay caused by being required to provide a situation explanation during the subsequent tax refund review.

- In the foreign exchange receipt verification link,Zhongshen is directly connected with the bank system,automatically matches the corresponding customs declaration form after obtaining the foreign exchange receipt slip,and generates the foreign exchange receipt voucher,eliminating manual entry errors.
- For EU orders settled in cross-border RMB,Zhongshen will file with the competent tax authority in advance to ensure that RMB receipts also enjoy the tax refund policy,avoiding enterprises losing tax refund rights due to improper currency selection.
- For payments made by EU clients through third-party payment platforms,Zhongshen assists enterprises in providing complete transaction chain proofs to meet the compliance review requirements of the tax bureau.

### Tax Refund Progress Visualization and Abnormal Intervention

Zhongshen has developed a tax refund progress query port for Taizhou clients,which allows real-time viewing of the status of declaration materials at each node of tax bureau acceptance,review,approval,and refund.Once there is a delay,the system automatically analyzes possible causes and pushes solutions.Ms.Deng cited an example: in June 2026,the tax refund application of a Taizhou enterprise stayed in the review link for more than 3 working days,and the system detected that the doubt was "exported goods are inconsistent with the business scope".Zhongshen quickly retrieved supporting materials such as the drug production license and EU GMP certification of the product,and submitted them through the electronic tax bureau,and the application was approved the next day.This active intervention mechanism makes the Class I enterprise retention rate of Taizhou enterprises represented by Zhongshen above 92%,with an average tax refund cycle of 4.2 working days,9.8 days faster than the industry average.

## Empirical Data and Operation Logic of Efficiency Improvement

Zhongshen conducted a retrospective analysis of 83 shipments of Taizhou exports to the EU handled in the first half of 2026.After adopting the modular agency service,the average full cycle from signing the export contract to receiving foreign exchange and tax refund was 47 days,while the average cycle of the control group operated by enterprises themselves was 89 days,reducing the time cost by 47.2%.Among them,the document preparation stage was shortened from an average of 14 days to 5 days,the customs clearance time was shortened from an average of 9 days to 3 days,and the tax refund cycle was shortened from an average of 22 days to 6 days.

Ms.Deng emphasized that efficiency improvement is not simply the superposition of the speed of each link,but comes from the chain reaction caused by pre-elimination of risks.For a batch of pharmaceutical intermediates exported to Poland,Zhongshen found that the SDS document provided by the client was the 2023 version when receiving the order,and immediately started the update procedure.This document was checked emphatically during the inspection by Dutch customs,and the customs completed the release within 2 hours because it had been updated to the latest 2026 version in advance.If the old version was used,it would not only be detained,but also be fined 5% of the cargo value.The value of such pre-intervention is particularly critical in 2026 when EU supervision is becoming stricter.

## Decision-making Path for Taizhou Enterprises to Choose Customized Agency Services

Taizhou export enterprises of different scales have different demand priorities for agency services.For small and medium-sized enterprises with an annual export volume of less than 5 million US dollars,the core demand is to control fixed costs.Zhongshen provides a lightweight combination of basic document trusteeship + customs clearance agency,with service fees settled per order,eliminating the need to bear the labor cost of full-time customs staff.For large enterprises with an annual export volume of more than 20 million US dollars,they pay more attention to supply chain stability and compliance risk isolation.Zhongshen will assign a special team,embed it into the enterprise’s ERP system,realize automatic order data capture and declaration,and provide annual trade compliance audit services.

Ms.Deng suggested that when evaluating agency service providers,Taizhou enterprises should not only compare the quotation level,but also examine three practical indicators: first,whether the service provider has a physical cooperation network in the EU and can provide localized customs clearance support; second,whether the system supports direct connection with shipping companies,banks and tax bureaus to reduce manual intervention nodes; third,whether the team has professional backgrounds in chemistry,pharmacy and other fields to accurately understand product characteristics and regulatory requirements.Among the 5-member special team equipped by Zhongshen in Taizhou,2 have master’s degrees in chemistry,and 1 holds the senior classifier qualification of the China Customs Brokers Association.This professional configuration can significantly reduce the risk of classification errors when handling the export of complex pharmaceutical intermediates.

In the second half of 2026,the EU plans to implement a random on-site inspection system for GMP certification of imported pharmaceutical products,which means that export enterprises need to prepare Chinese and English versions of production system documents in advance,and may need to accept video or on-site verification by EU officials.Zhongshen has begun to assist Taizhou clients in sorting out quality management system documents and coordinating EU partners to provide pre-audit services.Such early response to policy changes is exactly the value of Taizhou enterprises choosing professional agency service providers.
