2026 Full Process Detailed Analysis of Import Customs Declaration and Clearance Agency Services

Analysis of Core Processes of Import Customs Declaration and Clearance Agency Services

In 2026,as the core foreign trade hub in China,Shanghai’s import business volume increased by 12% year-on-year,with cross-border e-commerce imports and general trade imports accounting for more than 70% of the total.However,many enterprises encounter difficulties in the import process: declaration is rejected due to failed document review,container detention fees are incurred due to failure to clear customs in time after goods arrive at the port,and they do not know how to adjust operations after policy changes.Import customs declaration and clearance agency services are the key to solving such problems,helping enterprises efficiently complete the full process from goods arrival at the port to customs clearance and release.Next,combined with more than 20 years of service experience of Zhongshen,we will systematically sort out the core processes of agency services.

I.Pre-preparation and Document Review Stage: Lay a Solid Compliance Foundation

Stage Objective: Ensure all documents are complete and information is accurate,comply with the latest customs requirements,and avoid declaration failure.

Key Actions:

• Confirm core information of imported goods with customers,including HS code,quantity,weight,place of origin,trade mode (general trade/cross-border e-commerce,etc.);
• Review basic documents: bill of lading,commercial invoice,packing list,trade contract,certificate of origin,etc.;
• Assist in handling special documents: For special requirements such as 3C certification,import license,animal and plant quarantine certificate,inform customers of the handling process and timeline in advance.

Common Problems: Incorrect HS code classification (the customs updated the coding rules for some mechanical and electrical products in 2026),inconsistent document information (such as quantity difference between invoice and packing list),missing special documents (such as no health certificate provided for food imports).

Role of Zhongshen: We have a 5-member full-time document review team,each with more than 8 years of experience,who can accurately match the latest 2026 HS codes; we start document review 3 working days in advance,and immediately feedback to customers if problems are found (for example,Supervisor Hua’s team will synchronize the review progress in real time through an exclusive communication group); for special documents,we can assist customers to connect with third-party institutions for handling,so as to avoid delaying the declaration after goods arrive at the port due to document problems.

II.Goods Arrival at Port and Declaration Stage: Seize the Lead in Time Efficiency

Stage Objective: Complete electronic declaration within 24 hours after the goods arrive at the port to avoid port container detention fees.

Key Actions:

• Track cargo dynamics: Monitor the arrival time of goods in real time through the port system,and coordinate with the yard to reserve space in advance;
• Electronic declaration: Submit declaration data to the customs single window,including cargo information,tax calculation,trade mode,etc.;
• Manifest confirmation: Cooperate with the shipping company to complete the verification of manifest information and declaration data to ensure consistency.

Common Problems: Manifest information is inconsistent with actual goods (such as wrong container number),declaration data entry errors (such as unit price calculation deviation),declaration delay caused by congestion of customs system during peak hours.

Role of Zhongshen: We maintain long-term cooperation with Shanghai Yangshan Port and Waigaoqiao Port,and can obtain advance cargo arrival forecasts; the electronic declaration team is familiar with the latest upgraded single window system of the customs in 2026,with a declaration accuracy rate of 99%; in case of system congestion,we can submit declarations preferentially through the exclusive green channel (the right of Zhongshen as a Class A agency enterprise),which is 1-2 working days faster than ordinary enterprises.

III.Inspection and Release Stage: Pass Supervision Efficiently

Stage Objective: Pass customs inspection smoothly and complete release procedures within 1 working day.

Key Actions:

• Inspection preparation: After receiving the customs inspection notice,sort out the cargo list,original documents and other materials;
• On-site cooperation: Accompany customs personnel to conduct unpacking inspection and answer questions in time;
• Release processing: After passing the inspection,submit a release application,pay relevant taxes and fees (if necessary),and obtain the release note.

Common Problems: Increased inspection ratio (the inspection ratio for food and cosmetics rose to 15% in 2026) leads to long waiting time,inconsistency between goods and declaration found during inspection (such as the difference between actual weight and declaration exceeds 5%),and cumbersome release process (multiple submissions of materials are required).

Role of Zhongshen: We have rich experience in inspection cooperation,and can predict the key points of inspection in advance (for example,the production date of food goods will be checked emphatically); if the goods are inconsistent with the declaration,we can assist customers to analyze the reasons (such as weight change caused by package expansion),and supplement explanations according to customs requirements to reduce the probability of punishment; we have established a smooth communication mechanism with the customs inspection department,and can complete the release procedures within 2 hours at the fastest after inspection.

IV.Post-process Settlement and Archiving Stage: Clear and Transparent Closed Loop

Stage Objective: Accurately calculate various expenses,improve data archiving,and facilitate subsequent business inquiry.

Key Actions:

• Expense accounting: Statistics of agency service fee,customs duty/VAT,port sundry fees (container detention fee,storage fee,etc.),transportation fee,etc.;
• Provide details: Send the expense list to customers,marking the calculation basis of each expense;
• Data archiving: Sort out customs declaration forms,release notes,tax vouchers and other materials,and carry out electronic backup and paper archiving.

Common Problems: Vague expense details (such as sundry fees not marked with specific purposes),incorrect tax calculation (such as incorrect application of tariff rate),and data loss affecting subsequent tax rebates (such as loss of customs declaration form).

Role of Zhongshen: We upgraded the expense accounting system in 2026,which can automatically generate a detailed expense list (including the official website query link for customs taxes and fees),and customers can view it in real time through the exclusive background; the tax calculation team is familiar with the latest tariff policies (for example,the tariff on some agricultural products imported from Southeast Asia was reduced by 5% in 2026),with an accuracy rate of 100%; all materials are stored for 5 years,and customers can contact Supervisor Hua to retrieve them at any time,which will not affect subsequent export tax rebates or other businesses.
