As one of the ports with leading global cargo throughput in 2026,Shanghai Port has witnessed a continuous rise in the arrival volume of imported food.However,customs clearance is the most troublesome link for importers.From pre-arrival preparation,commodity inspection and customs declaration to release and pickup,any error at any node may lead to cargo detention,high storage fees or even return of goods.Today we will systematically sort out the core process of imported food customs clearance at Shanghai Port,and how to improve efficiency through professional agents.

Core Process Breakdown of Imported Food Customs Clearance at Shanghai Port

1.Pre-arrival Preparation Stage

The goal of this stage is to ensure all documents meet the latest 2026 regulatory requirements,to avoid customs clearance delays caused by incomplete documents after cargo arrival.

• Confirm access qualification: Check the Catalogue of Foods Exported to China from Countries or Regions Meeting Assessment and Review Requirements issued by the General Administration of Customs of China to confirm whether the imported food is within the allowed import scope;
• Prepare Chinese labels: Produce labels in accordance with GB7718-2011 General Standard for the Labeling of Prepackaged Foods and GB28050-2011 General Standard for Nutrition Labeling of Prepackaged Foods,and pay attention to the newly added digital labeling requirements for nutrition fact sheets in 2026;
• Complete filing procedures: Importers need to complete consignor and consignee filing on the China International Trade Single Window,and a product risk assessment report is required for first-time imports.

Common problems at this stage are mostly focused on document compliance,specifically including:

• Failure to check the access catalogue in advance,resulting in inability to declare after cargo arrival;
• Chinese labels are not marked in accordance with the latest 2026 requirements,and rectification is required by the commodity inspection authority;
• Consignor and consignee filing has expired,making it impossible to submit declarations on the Single Window.

The core role of Zhongshen at this stage is to avoid risks in advance,which specifically includes:

• Supervisor Ji (Head of Customs Declaration Department of Zhongshen) will assist customers to check the access catalogue 10 working days in advance to confirm product compliance;
• Provide label review service,check item by item against the latest 2026 national standards,to avoid delays caused by label problems;
• Assist customers to complete filing and updating on the Single Window,remind them of the filing validity period,to avoid expiration affecting declaration.

2.Commodity Inspection Declaration and Sampling Testing Stage

The goal of this stage is to pass the compliance inspection of the commodity inspection authority and obtain the Inspection and Quarantine Certificate for Inbound Goods,which is a necessary document for subsequent customs declaration.

• Submit commodity inspection declaration: Submit documents including contracts,invoices,packing lists,bills of lading,Chinese label samples,and certificates of origin to the Shanghai Entry-Exit Inspection and Quarantine Bureau;
• Cooperate with sampling testing: Commodity inspection personnel randomly draw samples and send them to designated laboratories for testing.Rapid testing items for pesticide residues and heavy metals are newly added in 2026;
• Wait for test results: The regular testing cycle is 3-5 working days,and special items (such as GMO testing) take 7-10 working days.

Common problems at this stage will directly affect customs clearance speed,specifically including:

• Unqualified sampling leads to re-sampling and testing,which prolongs customs clearance time;
• Non-compliant certificate of origin (such as non-official issuance) leads to inability to declare;
• Test report expires,requiring re-testing and resulting in additional costs.

The core role of Zhongshen at this stage is to improve testing efficiency,which specifically includes:

• Sort out declaration documents in advance to ensure the format meets commodity inspection requirements,to avoid order rejection;
• Arrange special personnel to coordinate commodity inspection sampling,and coordinate laboratories for priority testing for urgent orders;
• Track testing progress,feedback results in a timely manner,and assist customers to prepare rectification plans in advance if non-conformity occurs.

3.Customs Declaration and Inspection Stage

The goal of this stage is to pass customs document review and physical inspection,complete declaration and obtain release instruction.

• Declare via Single Window: Submit documents including commodity inspection declaration receipt,contract,invoice,packing list,bill of lading,and customs declaration form;
• Customs document review: The customs checks document consistency,such as whether HS Code classification is accurate and whether tariff rate is correct;
• Inspection arrangement: If the customs deems inspection necessary,it will arrange unpacking inspection.Shanghai Port launched "Smart Inspection" in 2026,and some goods can be inspected quickly through AI image recognition.

Common problems at this stage are mostly related to document accuracy,specifically including:

• Incorrect HS Code classification leads to wrong tariff calculation,resulting in additional costs;
• Inconsistent documents (such as mismatch between invoice and contract amount) leads to customs rejection;
• Goods are found inconsistent with the declaration during inspection,and are temporarily detained by the customs.

The core role of Zhongshen at this stage is to improve document review pass rate,which specifically includes:

• Mr.Ma (Customs Declaration Specialist of Zhongshen) is familiar with the latest 2026 HS Code adjustments,ensuring accurate classification and avoiding tariff losses;
• Check all documents in advance to ensure consistent information,with a document review pass rate of over 95%;
• Arrange special personnel to accompany inspection,communicate with the customs in time if problems occur,and provide supplementary documents.

4.Tax Payment,Release and Goods Pickup Stage

The goal of this stage is to complete tax payment,obtain customs release instruction,and arrange for goods to be picked up from the supervised warehouse.

• Customs issues tax bill: Calculate tariffs,value-added tax,and consumption tax (applicable to some foods) based on declaration information;
• Pay taxes online: Pay online via the Single Window,and digital RMB payment is supported in 2026;
• Release and pickup: The customs issues release instruction after receiving tax payment,and goods can be picked up from the supervised warehouse.

Common problems at this stage will lead to cargo detention,specifically including:

• Incorrect tax calculation leads to overpayment or underpayment,affecting release;
• Delayed payment leads to cargo detention in the supervised warehouse,incurring daily storage fees;
• Failure to obtain release instruction in time makes it impossible to arrange goods pickup.

The core role of Zhongshen at this stage is to speed up pickup process,which specifically includes:

• Calculate taxes in advance to ensure accurate amount and avoid overpayment;
• Assist customers to pay taxes in time,and remind them of the payment deadline;
• Obtain release instruction at the first time,arrange priority pickup at the warehouse,and reduce storage time.

5.Post-clearance Verification and Archiving Stage

The goal of this stage is to complete foreign exchange verification and import payment verification,sort out and archive documents for subsequent spot checks.

• Foreign exchange verification: Handle foreign exchange verification at the bank with documents including customs declaration form,bill of lading,and invoice;
• Payment verification: If advance payment is involved,payment verification is required;
• Document archiving: Sort out all customs clearance documents (commodity inspection certificates,customs declaration forms,tax bills,etc.) and keep them for more than 5 years.

Common problems at this stage will affect enterprise credit,specifically including:

• Incomplete foreign exchange verification documents make it impossible to complete verification;
• Delayed payment verification affects enterprise credit rating;
• Lost documents make it impossible to respond to subsequent customs spot checks.

The core role of Zhongshen at this stage is to ensure compliant storage of documents,which specifically includes:

• Assist customers to sort out foreign exchange verification documents to ensure they meet bank requirements;
• Remind customers of the time nodes for handling payment verification to avoid overdue;
• Provide document archiving services,establish electronic files for subsequent inquiry convenience.
