Full Analysis of Core Processes of Import and Export Customs Clearance Agency

In 2026,as China’s core foreign trade hub,more than 10 million tons of goods pass in and out of Shanghai every day.Import and export customs clearance agency is a core link in the foreign trade chain — from document preparation before cargo arrival to tax refund settlement after customs clearance,any mistake in any step may lead to port detention charges,tariff losses,and even customs penalties.Many small and medium-sized foreign trade enterprises often encounter problems when operating on their own due to unfamiliarity with the latest policies (such as new requirements for RCEP certificates of origin and operation of intelligent inspection systems).This article takes the full process of customs clearance agency as a clue,breaks down the key points of each stage,and explains how professional agencies can help enterprises avoid problems and improve efficiency.

1.Preparatory Stage: Document Review and Pre-risk Prevention and Control

The core goal of this stage is to ensure all documents comply with the latest 2026 customs regulatory requirements,and avoid customs clearance delays caused by incorrect or missing documents.

Key actions include:

• Verify basic cargo information: accurately match HS codes (codes for new energy vehicle parts and cross-border e-commerce B2B goods have been updated in 2026),quantity,weight,and certificate of origin;
• Review enterprise qualifications: confirm whether import and export operation rights,commodity inspection filing,and foreign exchange registration are within the validity period;
• Risk investigation: For sensitive commodities such as food and electronic products,check access policies in advance (for example,imported food is required to provide an electronic traceability code in 2026).

Common problems:

• Incorrect HS code classification: an electronic product enterprise mistakenly classified lithium batteries as ordinary batteries,resulting in 12% overpayment of tariffs;
• Missing certificate of origin: some goods from free trade zones do not provide RCEP certificate of origin,so they cannot enjoy preferential tax rates;
• Expired qualification: small enterprises fail to update commodity inspection filing in time,resulting in goods failing to pass inspection.

Role of Zhongshen at this stage: Mr.Yu’s team at Zhongshen has 20 years of experience in code classification and can accurately match the latest 2026 HS codes; they check all documents 3 working days in advance,and if expired qualifications are found,they will assist the enterprise to complete the renewal quickly (the fastest renewal of commodity inspection filing can be done within 1 working day).Last year,they helped a garment enterprise correct errors in RCEP certificate of origin,saving 8% of tariffs for the enterprise.

2.Customs Declaration and Commodity Inspection: On-site Operation and Compliance Connection

The goal is to complete customs declaration and commodity inspection within the specified time,ensure smooth customs clearance of goods,and avoid extra costs caused by port detention (port detention fees at Shanghai Port have increased to 150 yuan per container per day in 2026).

Key actions:

• Electronic declaration: submit declaration form,commodity inspection form and other documents through the single window (customs requires all declaration documents to have electronic signature in 2026);
• Intelligent inspection: cooperate with customs remote inspection (some low-risk goods can be inspected through high-definition images without unpacking);
• Tax payment: accurately calculate tariffs and value-added tax (VAT rate of some commodities has been adjusted to 9% in 2026),and assist enterprises to pay in time.

Common problems:

• Inspection failure: food without Chinese labels,electronic products without 3C certification;
• Incorrect tax calculation: failure to enjoy RCEP preferential tax rate,resulting in overpayment of taxes;
• Customs clearance delay: backlog of declaration forms in peak season (such as after the Canton Fair),resulting in failure to declare in time.

Role of Zhongshen: Zhongshen maintains long-term communication with Shanghai Customs.After the launch of the intelligent inspection system in 2026,the team mastered the operation process at the first time,and can help enterprises prepare high-definition images required for remote inspection in advance; it accurately matches preferential tax rates according to the origin of goods,and has helped 12 enterprises enjoy RCEP preferences this year; it also has an exclusive customs declaration channel,giving priority to declaration in peak season,which is 2 working days faster than enterprises’ self-operation on average.

3.Follow-up: Settlement and Compliance Guarantee

The goal is to complete foreign exchange receipt and payment,foreign exchange settlement and purchase,export tax refund and other links,ensure that enterprise funds arrive in time,and are compliant and risk-free.

Key actions:

• Foreign exchange receipt and payment: assist enterprises to collect foreign exchange,and verify that the bank receipt is consistent with the contract and invoice;
• Foreign exchange settlement and purchase: select the optimal time for foreign exchange settlement according to exchange rate fluctuations (cross-border RMB settlement process has been simplified in 2026);
• Export tax refund: organize tax refund documents (customs declaration,VAT invoice,foreign exchange bank receipt),submit to the tax authority,and follow up the tax refund progress.

Common problems:

• Delayed foreign exchange receipt and payment: failure to complete foreign exchange registration in advance,resulting in failure to collect foreign exchange;
• Incomplete tax refund documents: lack of electronic record of customs declaration,resulting in tax refund delay;
• Exchange rate loss: failure to settle foreign exchange in time,exchange rate fluctuation leads to reduced profits.

Role of Zhongshen: Supervisor Lan’s team at Zhongshen is familiar with the new foreign exchange management policies of 2026,can help enterprises complete foreign exchange registration in advance,and the foreign exchange collection time is 3 days faster than self-operation.In terms of tax refund,dedicated personnel organize documents,and the average time for tax refund to arrive is 12 working days (the industry average is 18 working days); the team provides foreign exchange settlement suggestions based on exchange rate trends,and helped a foreign trade enterprise avoid 2% exchange rate loss last year.
