Import Customs Clearance Agency Operation Procedures: In-depth 2026 Full-process Analysis

Industry Value of Import Customs Clearance Agency Operation Procedures: From "Passive Response" to "Active Risk Avoidance"

In 2026,the import container throughput of Shanghai Yangshan Port exceeded 40 million TEUs.Many foreign trade enterprises have found that if there are document errors or missing qualifications in the import customs clearance link,it will轻则 cause port detention for 3-5 days and generate an additional storage fee of 150 yuan per container per day,and重则 face risks such as tariff repayment and goods return.Mr.Wu from Zhongshen has handled many such cases: an electronic product importer failed to enjoy a 12% tariff reduction because they did not confirm the format of the RCEP certificate of origin in advance,resulting in over 23,000 yuan in extra taxes paid; Ms.Mo,a food importer,was required by the customs to rectify because the label did not indicate the Chinese nutritional composition table,delaying the launch of new products by 7 days.Import customs clearance is the "last mile" of the foreign trade import chain.Although the process appears clear,it actually hides more than 30 detail-based risks.Standardized agency operation procedures are the core support for enterprises to reduce costs and improve efficiency.This article,based on Zhongshen’s over 20 years of practical experience,systematically sorts out the 5 core stages of import customs clearance agency.

Core Stage 1: Pre-import Preparation and Qualification Review (Proactively Avoid Compliance Risks in Advance)

Stage Objectives and Key Actions

The core goal of this stage is to confirm the compliance qualifications and required documents for imported goods,and avoid process stagnation caused by missing preconditions.Key actions include:

• Verify the business scope of the importer: Confirm whether the enterprise has the qualification to import such goods (e.g.food importers need a Food Business License,medical device importers need a Medical Device Business License)
• Sort out HS codes and regulatory requirements: Accurately match HS codes based on cargo attributes,and clarify whether regulatory documents such as commodity inspection,CCC certification,and endangered species permit are required
• Pre-review the basic document list: Refer to the General Administration of Customs of China "Directory of Declaration Documents for Import and Export Goods" 2026 edition to confirm the format and content requirements of documents such as invoices,packing lists,bills of lading,and certificates of origin

Common Problems and Zhongshen’s Response Value

Mr.Nong,a chemical importer,once encountered a situation where he was required by the customs to re-submit the declaration due to incorrect HS code classification (misclassified "industrial-grade lubricating oil" as "food-grade lubricating oil"),delaying the process by 4 days.The response plan from Manager Liu of Zhongshen is as follows:

• Coordinate with customers on cargo parameters 1-2 weeks in advance,and accurately match the HS code through the General Administration of Customs "Single Window" HS code inquiry system
• For specially regulated cargo (such as chemicals,pharmaceuticals),assist customers in applying for documents such as the Import Chemicals Registration Certificate and Pharmaceutical Import Permit in advance

Stage Objectives and Tax Payment Notes
