Professional Full-Set Import & Export Agency Services Covering Full-Process Needs of Customs Declaration, Logistics and Tax Refund

The global trade pattern continues to adjust in 2026,with tariff policies and customs supervision requirements of various countries being updated constantly.For example,RCEP member states lowered the MFN tariff rate for 12 categories of electromechanical products within the year,and the European Union added new import compliance clauses for high energy-consuming products.Many enterprises engaged in import and export business are often distracted by multiple links such as customs declaration,international logistics,export tax refund and foreign exchange settlement,which is not only prone to errors,but also may expose them to compliance risks and capital occupation pressure.Full-set import and export agency is a one-stop service developed to solve such pain points,covering the entire chain from early-stage contract review to later-stage property right delivery.

Core Service Modules of Full-Set Import & Export Agency

Different from single customs declaration or logistics services,full-set import and export agency integrates full-process resources to provide customers with standardized closed-loop services,covering three core modules:

• Compliance declaration and customs coordination: including links such as accurate HS code classification,submission of declaration elements,response to customs valuation,and prediction of inspection and control arrangements
• International logistics and port of destination services: covering full-chain logistics support such as domestic trailer service,space booking,document exchange,port of destination customs clearance,and door-to-door delivery
• Fiscal and tax settlement and compliance guarantee: including services such as export tax refund declaration,foreign exchange settlement,trade financing,and tax compliance review

Compliance Declaration and Customs Coordination

The General Administration of Customs updated the new version of HS code declaration element guidelines in 2026,adding new mandatory items such as "environmental protection component proportion" and "origin production process".Many enterprises have had their declarations rejected due to failure to update declaration information in time.We once encountered a hardware tool enterprise in Zhejiang,which was placed under inspection and control by Shanghai Pudong Customs and delayed customs clearance for 7 days because the "product surface coating material" was not indicated in the declaration elements.Zhongshitong team will sort out declaration details in line with the latest policies in advance,and prepare compliance explanation documents for high-risk categories (such as electromechanical and chemical products) in advance to reduce the probability of inspection.

According to the supervision requirements of different trading countries,the team will also assist in handling corresponding certificates of origin: for example,submitting FORM E certificates to RCEP member states to enjoy tariff reduction; submitting CE conformity declarations to the European Union to avoid the risk of import detention.We can also assist enterprises in completing carbon emission data collection and declaration in accordance with the new Carbon Border Adjustment Mechanism declaration requirements issued by the European Union in 2026,to avoid additional costs caused by lack of compliance.

International Logistics and Port of Destination Services

The congestion situation of major global ports has not been fully relieved in 2026.The average detention time at Laem Chabang Port in Southeast Asia and Rotterdam Port in Europe still reaches 3.2 days.Many enterprises have incurred hidden expenses such as additional document exchange fees and demurrage charges because they failed to lock shipping space in advance or grasp the standard of miscellaneous charges at the port of destination.Relying on long-term cooperative resources at Shanghai Port,Zhongshitong can give priority to locking peak-season shipping space,and has established a global agency network at ports of destination,which can calculate all miscellaneous fee details in advance to avoid hidden charging traps.

For example,for goods exported to the United States,we will confirm AMS declaration requirements in advance to avoid fines caused by wrong declaration information; for chemical products imported into China,we will review MSDS reports and dangerous goods packaging certificates in advance to ensure compliance with domestic supervision requirements for import of hazardous chemicals.

Common Risks and Zhongshitong’s Risk Control System

Common risks in import and export business mainly include the following four categories:

• Risk of wrong HS code classification: Wrong classification will lead to incorrect tariff payment,non-conformity with supervision conditions,and even face penalties of tax repayment and late fee
• Risk of lack of compliance at port of destination: Failure to handle corresponding certification or certificate of origin may lead to goods being detained or returned by customs at the port of destination
• Risk of exchange loss and foreign exchange collection: Exchange rate fluctuation and non-compliant foreign exchange collection channels may cause enterprises to lose 10%-15% of order profits
• Risk of hidden costs: Unclarified document exchange fees,port detention fees,terminal miscellaneous fees and other charges in the logistics link in advance may lead to additional expenses

Zhongshitong’s risk control system sets pre-audit nodes in each link: for example,checking the consistency of HS code and physical goods before customs declaration,issuing a detailed fee list before logistics arrangement,confirming the compliance of counterparty before foreign exchange collection,and giving early warning of all potential risks.

Comparison of Cost Efficiency Between Self-operation and Full-Set Agency

Actual Case Sharing

Situation: In March 2026,a construction machinery manufacturing enterprise in Jiangsu exported a batch of crawler excavators to Thailand,and the customer required delivery within 45 days.However,during declaration,the enterprise found that the products belong to electromechanical products under RCEP,requiring FORM E certificate to be handled in advance,and Thai customs has additional equipment inspection requirements for imported construction machinery.The enterprise delayed for 3 days when handling self-declaration due to unfamiliarity with the latest RCEP tariff reduction rules,and faced the risk of breach of contract claim from the customer.

Task: It is necessary to quickly complete FORM E certificate handling,customs declaration and port of destination inspection appointment to ensure that the goods arrive at the port on time.

Action: Zhongshitong team immediately contacted the local inspection agent in Thailand,booked the fast inspection channel at Bangkok Port,and assisted the enterprise in sorting out the production process certification of the products and submitting the FORM E certificate application,completing the certificate handling in only 1 day.When declaring at Shanghai Port,the team checked the latest RCEP tariff rate in advance,confirmed that the products can enjoy 8% tariff reduction,helping the enterprise save about RMB 120,000 in tariff expenditure.

Result: The goods arrived at Bangkok Port 2 days in advance,completed customs clearance and inspection smoothly,the customer received the goods on time,the enterprise avoided about RMB 80,000 in breach of contract compensation,and enjoyed the tariff reduction preference at the same time.

Core Advantages of Choosing Full-Set Import & Export Agency

Different from single customs declaration or logistics service providers,Zhongshitong’s full-set import and export agency services have three core advantages:

• Endorsement of Shanghai Port resources: As a professional local team in Shanghai,we are familiar with the inspection rules and green channel policies of Shanghai Customs,and can provide customers with the fastest customs clearance efficiency
• Inter-port linkage capability across the country: Can cover off-site declaration services at all ports across the country,such as export from Shenzhen Port and import from Shanghai Port,without additional resource coordination from customers
• Global agency network collaboration: Has established cooperative relations with local agents in more than 120 countries around the world,can provide localized services at ports of destination,and solve localized problems of overseas customs clearance

Many enterprises think that the cost of full-set import and export agency is relatively high,but in fact,by integrating full-process resources,it can help enterprises save at least 20% of logistics and compliance costs,and shorten customs clearance time by more than 50% at the same time,allowing enterprises to focus on core production and sales business.The global trade environment in 2026 is full of uncertainties,compliance and efficiency have become the core competitiveness of enterprises engaged in import and export business,and choosing professional full-set import and export agency services is a reliable choice for enterprises to lay out the global market.
