Full Process of Pre-packaged Food Import Customs Clearance and Analysis of Common Issues

Core Process of Pre-packaged Food Import Customs Clearance and Pitfall Avoidance Guide

Pre-packaged food import customs clearance is a key link in the foreign trade chain that directly affects the efficiency of cargo circulation.As China’s core port for imported food,Shanghai has further refined policies on label traceability and quarantine requirements in 2026.Many enterprises face cargo detention and delays at ports due to unfamiliarity with the process and inconsistent documents.Based on Zhongshen’s 20 years of industry experience,this article systematically sorts out the core stages of customs clearance to help enterprises complete import efficiently.

I.Pre-preparation: Document and Qualification Review (Goal: Avoid declaration rejection)

The core of this stage is to confirm that all documents comply with the latest 2026 policies.Key actions include:

• Verify whether the imported food is included in China’s Catalogue of Foods Permitted for Import (access for some plant-based beverages was added in 2026)
• Prepare Chinese labels (Shanghai Port Traceability QR Code and Nutrition Facts Table shall be marked)
• Sort out commercial documents: contract,invoice,packing list,ocean bill of lading (shall be consistent with the actual goods)
• Complete Import Food Consignee Filing (Shanghai Port requires submission 3 working days in advance)

Common problems: Some customers fail to notice the newly added "traceability code marking position" requirement in 2026 (it shall be placed in a prominent position on the label),resulting in failure of label review; some enterprises are intercepted by the system during declaration due to expired consignee filing.

Role of Zhongshen: Provide the latest 2026 label templates,assist customers in checking key information such as traceability codes; review the access catalogue for free,and exclude prohibited products in advance; assist in completing consignee filing quickly (completed within 1 working day at Shanghai Port,2 days faster than customers applying on their own).Last year,for a batch of imported probiotic powder of Mr.Kang,due to incorrect position of the label traceability code,Zhongshen assisted in modification and passed the review within 1 day,avoiding a container detention charge of 3,000 RMB.

II.Coordination Before Cargo Arrival at Port (Goal: Seamless connection with port operations)

The following shall be completed before the cargo arrives at the port:

• Confirm the shipping company’s arrival notice (confirmation 24 hours in advance is required for Shanghai Yangshan Port / Waigaoqiao Port)
• Arrange warehousing reservation (bonded warehouses cooperating with Zhongshen can provide temporary storage)
• Make advance declaration (if the cargo meets the conditions for "advance declaration",1-2 days can be saved)

Common problems: Some customers do not reserve warehousing in advance,resulting in no storage place after the cargo arrives at the port and incurring port demurrage charges; some enterprises fail to confirm the arrival time of the shipping company and miss the advance declaration window.

Role of Zhongshen: Connect with 12 core bonded warehouses in Shanghai to lock storage space in advance; track the dynamics of shipping companies in real time to ensure smooth advance declaration; if the cargo needs temporary storage,7 days of free bonded storage can be provided (new service in 2026).

III.Core Link of Customs Clearance Declaration (Goal: Pass the declaration in one attempt)

At this stage,complete declaration materials shall be submitted to the customs.Key actions:

• Enter information into the declaration system (Shanghai Customs Single Window) to ensure accurate HS codes (codes for some snacks were updated in 2026)
• Upload all documents,including health certificate,label review form,etc.
• Cooperate with customs inspection (if selected,samples and relevant explanations shall be prepared)

Common problems: Incorrect HS codes lead to deviation in customs duty calculation; health certificates not updated to the 2026 version are required to be supplemented by the customs.

Role of Zhongshen: With Class A Qualification accredited by the customs,the declaration pass rate reaches 98%; HS codes are checked by specialists with more than 5 years of experience to avoid customs duty errors; if selected for inspection,specialists will accompany the whole process,prepare samples and explanatory materials,and reduce inspection time (on average 4 hours faster than customers handling it on their own).

IV.Quarantine,Inspection and Release (Goal: Complete quarantine and certificate issuance quickly)

The quarantine link is the key point of pre-packaged food customs clearance,and "rapid microbial testing" is added to the requirements in 2026:

• Submit quarantine application to Shanghai Entry-Exit Inspection and Quarantine Bureau
• Cooperate with sampling (3-5 samples are required for some foods)
• Wait for quarantine results (3-5 working days for regular foods,7 working days for special foods)

Common problems: Samples do not meet quarantine standards (e.g.excessive mold in some imported chocolates); failure to prepare the certificate of origin required for quarantine in advance leads to delays.

Role of Zhongshen: Review materials required for quarantine in advance to ensure that the certificate of origin meets the requirements; connect with the rapid testing channel of the inspection and quarantine bureau,shortening the quarantine time for regular foods to 2-3 working days; if there are problems with the samples,assist customers in providing rectification plans (such as replacing batches).Last year,for a batch of imported juice of Mr.Jian,due to excessive sugar content in the samples,Zhongshen assisted in contacting the supplier to replace the qualified batch,avoiding the return of the entire batch of goods.

V.Follow-up Warehousing and Distribution (Goal: Deliver to customers efficiently)

The following shall be completed after release:

• Take the goods out of the bonded warehouse (customs duty and value-added tax shall be paid)
• Arrange domestic distribution (next-day delivery service is available in Shanghai and surrounding areas)
• Provide a full set of customs clearance documents for subsequent foreign exchange settlement and financial accounting

Common problems: Delayed domestic distribution affects customers’ sales; failure to provide customs clearance documents in time makes it impossible for the finance department to complete accounting.

Role of Zhongshen: Cooperating logistics suppliers cover 30 provinces and cities across the country,with next-day delivery in areas surrounding Shanghai; a full set of customs clearance documents is provided within 1 working day after release,assisting customers in completing foreign exchange settlement and tax refund procedures.

Pre-packaged food import customs clearance involves multi-department linkage,and policies are updated frequently in 2026,so it is easy to encounter pitfalls when operating by yourself.Zhongshen has focused on customs clearance at Shanghai Port for 20 years,predicting risks in advance at each link to help customers save time and cost.For example,last year,a batch of imported nuts of Mr.Cheng was almost delayed due to label problems.Zhongshen assisted in modifying the label and passed the review within 1 day,avoiding a container detention charge of 5,000 RMB.Choosing a professional agent can make the import process smoother and allow you to focus on your core business.
