2026 Types of Companies Requiring Import Customs Clearance and Full Process Operation Guide

Key Role of Import Customs Clearance in the Foreign Trade Chain

Import customs clearance is not a simple declaration action,but a core link that determines whether goods can be put into storage on time and whether costs are controllable.In 2026,customs supervision rules are further refined,the inspection rate has increased year-on-year,and the risk cost of self-operation by enterprises has increased significantly.From commodity access assessment to document design,from on-site inspection coordination to follow-up foreign exchange processing,errors at any node may lead to port detention,fines or even return of goods.Zhongshen has been deeply engaged in the industry for more than 20 years,and has handled import cases covering machinery,chemicals,food,electronic products and other fields,and is familiar with the practical operation standards of various regulatory departments at Shanghai Port.This article systematically sorts out the types of enterprises that need to handle import customs clearance,and disassembles the whole process into four core stages,explaining the objectives,key actions and common problems of each stage,so as to help enterprises establish a clear operation framework.

Stage 1: Enterprise Qualification and Commodity Access Assessment

The goal of this stage is to confirm that the enterprise has import qualification and the commodities meet China’s access requirements before the goods are shipped,so as to avoid the situation that the goods cannot be declared after arriving at the port.Key actions include checking whether the business scope of the business license covers the relevant commodity categories,querying the customs HS code and confirming the supervision conditions,and verifying whether special approval documents such as 3C certification,import license,animal and plant quarantine certificate are required.Common problems are concentrated in the misjudgment of supervision conditions caused by incorrect code classification,and the lack of pre-approval documents for special commodities.In 2026,customs access review for chemicals and old electromechanical equipment is particularly strict,so advance verification is even more important.

Zhongshen’s role in this stage is to provide commodity pre-classification services.The customs affairs team led by Manager Yuan will issue a classification proposal in advance according to the product technical parameters and verify the supervision conditions.Last year,a manufacturing enterprise planned to import old CNC machine tools.During the pre-examination,Manager Yuan found that the manufacturing year of the equipment exceeded the age limit specified by the customs,and promptly advised the customer to adjust the procurement plan,avoiding the loss of return after the goods arrived at the port.For commodities that need to apply for automatic import licenses,Zhongshen will guide customers to prepare application materials two months in advance to ensure that the certificates are completed before the goods arrive at the port.

Stage 2: Document Preparation and Declaration Scheme Design

The goal of document preparation is to make all declaration documents highly consistent in data logic,and withstand customs valuation and classification queries.Key actions include guiding foreign sellers to provide commercial invoices and packing lists that meet the requirements of Chinese customs,verifying whether the format of the certificate of origin is accurate,and designing a reasonable declaration price structure.In 2026,customs inspection efforts for price fraud have increased.If the declared price is more than 15% lower than the average price of similar commodities in the same period,the system will automatically trigger a price query.Common problems are concentrated in the inconsistency between invoice price and foreign exchange payment amount,incorrect consignee information on the certificate of origin,and inconsistency between the weight and volume on the packing list and the bill of lading.

Zhongshen will design the optimal declaration scheme for customers at this stage.In the chemical import project led by Ms.Yao,the invoice provided by the foreign supplier combined freight and cargo value,which would lead to a false increase in the tariff base.Zhongshen guided the supplier to split the invoice and list the international freight separately,which reasonably reduced the dutiable value.For commodities with royalty fees,Zhongshen will help determine whether the fee should be included in the dutiable value and prepare corresponding written explanation materials.In the document review link,Zhongshen implements a double review system to ensure that documents are consistent with each other and documents are consistent with goods.

Stage 3: On-site Inspection and Tax and Fee Processing

The goal of the on-site inspection stage is to cooperate with the customs to complete the inspection and release of goods,timely handle problems found in the inspection,and accurately calculate and pay taxes and fees.Key actions include preparing relevant technical materials according to inspection instructions,explaining the functional principles of commodities on site,and providing supplementary explanations for classification or price questions raised during inspection.In 2026,the inspection rate for electromechanical and food commodities at Shanghai Port remains at a high level.Common problems are concentrated in the inconsistency between the goods model and the declaration found during inspection,or the customs queries the declared price and requires the provision of foreign exchange payment vouchers and correspondence.

Zhongshen deploys experienced field staff in the on-site inspection link.In the batch of imported electronic products led by General Manager Zou,the customs raised classification questions about a certain chip model.Zhongshen’s field staff presented the product specification and technical white paper on the spot,and communicated with the customs classification department by phone,finally maintaining the original classification and avoiding the delay of document modification.In terms of tax and fee processing,Zhongshen’s customs affairs system is connected with the customs tax library in real time,which can accurately calculate tariffs,value-added tax and consumption tax,and provide a variety of tax payment schemes.For cases requiring security deposit,Zhongshen assists customers in preparing application materials to speed up the release.

Stage 4: Post-release Matters and Risk Management

The goal after the release of goods is not only to pick up the goods and put them into storage,but also to complete follow-up work such as foreign exchange verification,document archiving,and risk file establishment.Key actions include timely handling of foreign exchange payment procedures,sorting out a full set of customs declaration documents for archiving,and reviewing the abnormal points in this customs clearance process.In 2026,the State Administration of Foreign Exchange has stricter verification of large-value foreign exchange payments,requiring enterprises to provide complete trade chain certificates.Common problems are concentrated in being questioned by the foreign exchange bureau due to the long interval between foreign exchange payment time and customs declaration time,or being required to supplement price certification materials in the post-customs audit.

Zhongshen provides a full chain service covering customs declaration,transportation,warehousing,foreign exchange and tax refund.After the completion of Mr.Huo’s mechanical parts import project,Zhongshen helped sort out a full set of customs declaration forms,invoices,packing lists,waybills and foreign exchange payment vouchers,and established a complete trade file.When the customs launched a follow-up price audit three months later,Zhongshen quickly provided all supporting documents to prove that the declared price was true and reasonable,and the case was successfully closed.Zhongshen will also establish a commodity database for customers,recording the customs recognition results of each classification to provide reference for subsequent imports.

Enterprises That Must Handle Import Customs Clearance

Not all enterprises involved in import business are aware that they need professional customs clearance services.The following three types of enterprises especially need to entrust professional agents:

• Trading companies that carry out import business for the first time,which lack experience in customs rules and port operations,and are prone to errors in document preparation and on-site disposal links.
• Production-oriented enterprises purchasing foreign equipment or raw materials,which usually do not have full-time customs affairs personnel,and face high classification and valuation risks due to complex technical parameters of imported commodities.
• Cross-border e-commerce and new retail enterprises,which have high import frequency,multiple categories and strict timeliness requirements,and need agents to provide rapid response and batch processing capabilities.

Zhongshen’s customers cover large manufacturing enterprises and start-up foreign trade companies.General Manager Guan’s food trading company was just established last year,and Zhongshen intervened from the first order,providing full guidance from supplier audit to label audit.The core criterion for judging whether a company needs import customs clearance services lies not in its scale,but in whether it has professional customs affairs capabilities.Zhongshen provides customized service schemes according to the customer’s import frequency and commodity complexity,which not only ensures compliance,but also controls operation costs.

Core Value of Zhongshen’s Services

Import customs clearance is not an isolated link,but deeply intertwined with foreign exchange,taxation and transportation.The value of Zhongshen’s more than 20 years of accumulation is reflected in three levels: prediction ability,coordination ability and system ability.As customs supervision becomes stricter in 2026,the time cost and risk cost of self-operation by enterprises are far higher than the agency fee.Choosing Zhongshen means converting uncertain risks into certain service costs,letting professional teams handle professional affairs,and allowing enterprises to focus on core business expansion.
