# Full Process Analysis and In-depth Compliance Sorting of Imported Food Customs Declaration Agency at Shanghai Port

## Realistic Dilemmas and Breakthrough Ideas for Customs Clearance of Imported Food at Shanghai Port

In the first quarter of 2026,the value of imported food through Shanghai Port increased by 17.3% year-on-year,with EU dairy products,Southeast Asian aquatic products,and Australian meat accounting for the main share.A trading company where Ms.Xue works represented a batch of Greek sheep cheese at the beginning of the year.After the goods arrived at the port,they were detained and inspected due to non-standard labeling on the sanitary certificate,and the costs incurred during the ten-day detention almost swallowed all the profits.This situation is not an isolated case; the risks of customs clearance delays,return,and even destruction for imported food at Shanghai Port always exist.Dynamic adjustments to regulatory policies,detailed and strict document requirements,and inconsistent enforcement of quarantine standards constitute the three tests that importers must face.The Zhongshen team has handled more than 2,000 food import projects in the past 20 years and found that most problems do not stem from the policies themselves,but from enterprises’ insufficient grasp of process nodes and insufficient attention to compliance details.

## Document Pre-examination Stage: Compliance Foundation Determines the Upper Limit of Customs Clearance

The document system for imported food is far more complex than that of ordinary goods.Take EU dairy products as an example: five types of documents are indispensable,including certificate of origin,sanitary certificate,composition analysis report,label sample,and the registration number of the overseas production enterprise in China.In March 2026,the General Administration of Customs updated the "Regulations on the Administration of Registration of Overseas Production Enterprises for Imported Food",requiring that overseas production enterprises of dairy products must be registered in China and obtain a unique number,which must be clearly marked on the sanitary certificate.Mr.Lu’s enterprise once failed to declare the entire batch of goods because the sanitary certificate provided by the supplier did not have the updated registration number,and eventually missed the sales season.

Zhongshen first activates the document pre-examination mechanism after accepting an order.Reviewers will check page by page whether the official seal of the sanitary certificate,the handwriting of the veterinarian’s signature,and the certificate number rules comply with the official templates of EU member states.For label samples,the team checks 12 details such as the order of ingredients list,allergen labeling,and nutrition label format in accordance with the "General Rules for Labeling of Prepackaged Foods" (GB 7718-2026) and the newly revised "Inspection Procedures for Imported Food Labels".There was once a batch of Italian mozzarella cheese that used the word "natural" on the label but did not provide relevant certification materials.The reviewers requested rectification in advance,avoiding the risk of being judged unqualified during port inspection.

Another key task in the pre-examination stage is commodity classification and tax rate calculation.There are many easily confused items in food classification.For example,the tax rates differ by nearly 10 percentage points between modulated milk powder with milk content exceeding 95% and solid drinks with milk content below 80%.Zhongshen’s classifiers will make comprehensive judgments based on product formulas,production processes,and industry standards to ensure the accuracy of the declared tax number.At the same time,the team will calculate tariffs,value-added tax,and possible consumption tax in advance to provide customers with a clear cost budget.

- Check the official seal of the sanitary certificate and the handwriting of the veterinarian’s signature page by page to confirm the authenticity of the certificate
- Check 12 details of label samples,including ingredient order,allergen labeling,and nutrition label format
- Accurate commodity classification and tax rate calculation to avoid tax differences caused by incorrect tax number declaration

## Port Customs Declaration Link: Accurate Declaration and Dynamic Communication

After completing the document pre-examination,Zhongshen will declare in advance to Shanghai Customs three days before the goods arrive at the port.The key information that needs to be entered at this time includes: the registration number of the overseas production enterprise,the percentage of product ingredients,production date and shelf life,storage conditions,information of the responsible unit in China,etc.Since 2026,Shanghai Customs has implemented the "Smart Supervision System for Imported Food",which requires automatic system comparison between declared data and overseas official certificate information.Any slight difference will trigger a manual inspection instruction.

A batch of Australian frozen beef in charge of Director Ning encountered a new problem during declaration.The customs system showed that the registration status of the slaughterhouse was "suspended for import",but the issuance date of the sanitary certificate provided by the customer was before the suspension announcement.Zhongshen immediately activated the emergency mechanism,submitted a written explanation to the customs,and attached the slaughter time certification document issued by the Australian authorities,proving that the batch of goods was produced before the suspension order took effect,which complied with the principle of "non-retroactivity of law".After three working days of communication and supplementary materials,the customs finally accepted the declaration and the goods were released.

Another difficulty in the customs declaration link is price declaration.Imported food often involves non-goods value such as brand licensing fees,technology transfer fees,and packaging design fees.Whether these fees should be included in the dutiable value directly affects tax payment.Zhongshen will,in accordance with the "Measures for the Examination and Determination of Dutiable Value of Import and Export Goods by the Customs",assist customers in sorting out the price composition,prepare supporting materials such as royalty allocation calculation forms and trademark license agreements,and ensure that the price declaration is compliant and reasonable.

- Declare key information to Shanghai Customs three days in advance to ensure that the data is completely consistent with the official certificate
- Sort out price composition and allocate royalties,prepare supporting materials for dutiable value
- Emergency communication mechanism for abnormal situations,quickly respond to customs questions and system warnings

## Commodity Inspection and Quarantine Stage: On-site Cooperation and Rapid Response

Food imports will inevitably face commodity inspection and quarantine.In 2026,Shanghai Port implements 100% box opening inspection for high-risk foods,and adopts the "double random" inspection mode for medium and low-risk foods.The inspection content covers three aspects: label consistency check,sensory inspection,and sampling for inspection.A batch of Thai coconut water imported by Mr.Ai was judged to have non-compliant labels during inspection,because the Chinese label did not mark "coconut pulp content",and the expression "with coconut pulp" on the original English label was recognized as a substantive ingredient.

Zhongshen provides full-process on-site inspection services.The day before the inspection,the team will recheck the stacking position of the goods and the label pasting situation to ensure that the goods and documents match.On the day of the inspection,the on-site staff will bring all original documents,label filing vouchers,and ingredient description materials to cooperate.In case of sampling for inspection,the team will assist customs officers in standard sampling and sealing,and track the laboratory test progress in real time.Generally,microbial index testing takes 5 working days,and additive and pollutant testing takes 7 working days.Zhongshen has established a working docking mechanism with laboratories such as the Shanghai Institute for Food and Drug Control,which can obtain feedback immediately when testing abnormalities occur,and assist customers in data interpretation and risk assessment.

For minor non-conforming items found during inspection,Zhongshen will immediately start the rectification procedure.For example,problems such as insufficient label font height and non-standard shelf life printing format can be technically rectified under customs supervision without return.In April 2026,a batch of French butter was required to be rectified because the Chinese label did not mark "trans fatty acid content".Zhongshen reprinted compliant labels and completed pasting within 24 hours,and the goods were allowed to be released the next day,minimizing losses.

- Cooperate on-site for label consistency check and sensory inspection,bring all original documents for inspection
- Track the sampling and inspection process,obtain real-time laboratory test progress and abnormal feedback
- On-site rectification of minor non-conforming items,reprint and paste labels within 24 hours

## Special Category Response: Dairy Products,Meat,Aquatic Products

Different food categories face differentiated regulatory requirements.In addition to conventional documents,dairy product imports also need to provide the "Entry-Exit Quarantine License for Animals and Plants",and customs clearance must be completed within the validity period of the certificate.Zhongshen has established a license term early warning mechanism to remind customers to renew the license 30 days in advance,avoiding goods return due to expired documents.For infant formula milk powder,an additional product formula registration certificate is required,and the Chinese label must be directly printed on the smallest sales package and cannot be pasted on.

Meat product supervision is more strict.Imported meat must come from enterprises listed in the "List of Meat Products from Countries or Regions Meeting Evaluation and Review Requirements for Export to China" published by the General Administration of Customs.Each batch of goods needs to provide a veterinary sanitary certificate corresponding to the production batch number,and the container number and seal number must be completely consistent with those marked on the certificate.When accepting an order,Zhongshen will first check whether the production enterprise is on the access list,and verify whether the certificate information provided by the customer matches the actual information of the goods.There was once a batch of Brazilian chicken detained by the customs because the veterinarian’s signature was suspected of being forged.Zhongshen assisted the customer in contacting the Brazilian official competent department to identify the authenticity of the signature,and finally confirmed that it was a problem with the clarity of the scanned copy,avoiding major losses.

Aquatic product imports focus on heavy metals and veterinary drug residues.The 2026 new version of the "National Food Safety Standard for Limits of Contaminants in Food" has adjusted the limit standards for cadmium and methylmercury in aquatic products,and some high-end seafood products face stricter testing.Zhongshen will require overseas suppliers to provide self-inspection reports from the past six months in advance,and advise customers to entrust a third-party institution for pre-testing before shipment to ensure compliance with Chinese standards.For fresh aquatic products,timeliness is life.Zhongshen has opened a green channel to ensure that the goods are declared within 6 hours after arriving at the port and inspected and released within 24 hours.

- Dairy Products: Early warning of "Entry-Exit Quarantine License for Animals and Plants" term and special review of infant formula milk powder labels
- Meat Products: Dynamic check of access list and accurate matching of veterinary sanitary certificate information
- Aquatic Products: Pre-testing suggestions for heavy metals and veterinary drug residues,green channel for fast customs clearance of fresh products

## Case Review: A Practical Risk Avoidance Exercise for EU Dairy Product Imports

In February 2026,Ms.Xue’s company planned to import three containers of Greek yogurt with a value of about 800,000 euros.During the order review,Zhongshen found that the sanitary certificate provided by the customer did not mark the registration number in China,and the product formula contained the strain "Streptococcus thermophilus" but did not provide a strain identification report.According to the latest regulations,dairy products containing probiotics must provide a strain identification report to prove their safety and functionality.

The team immediately activated the risk early warning mechanism.First,the Greek supplier was required to supplement and provide the latest sanitary certificate with the registration number in China clearly marked.Second,the supplier was coordinated to contact the strain supplier to obtain the strain identification report,and a professional translation agency was arranged to translate the report into Chinese.At the same time,the Chinese label was redesigned to clearly mark the strain name and strain number in the ingredients list.All these tasks were completed before the goods were loaded.

After the goods arrived at Shanghai Yangshan Port,the customs system comparison showed that all document information was consistent,no manual inspection instruction was triggered,and they successfully entered the random inspection link.The inspection officers checked the labels on site and found no abnormalities in sensory inspection,and the microbial indicators and additive items sampled for inspection were qualified.The entire batch of goods took only 4 working days from declaration to release,which was a full week earlier than the customer’s expectation.Ms.Xue later calculated that the fast customs clearance saved her about 120,000 yuan in detention and refrigeration fees,and the products were put on the shelf in time to catch the consumption peak after the Spring Festival.

## Service Value of Zhongshen: From Process Execution to Pre-emptive Risk Control

Imported food customs declaration is not just simple document transfer and system entry,but a comprehensive test of regulatory understanding,process control,and resource integration.The core competitiveness accumulated by Zhongshen over 20 years lies in pre-emptive risk control at the beginning of the business.The document pre-examination mechanism intercepts about 85% of potential compliance problems,the on-site inspection service increases the inspection pass rate to more than 98%,and the special response capability for special categories ensures that high-risk goods can also find the optimal customs clearance path.

In 2026,the smart supervision system was fully launched at Shanghai Port,with a higher degree of automatic data comparison,which means that the accuracy requirements for preliminary preparation are more stringent than ever before.The intelligent document review platform invested and built by Zhongshen can automatically identify the authenticity of certificates,compare label compliance,and warn of license terms,increasing the efficiency of manual review by three times.At the same time,the team maintains regular communication with customs,commodity inspection,and industry associations to ensure the timeliness and accuracy of policy interpretation.

For importers,the essence of choosing a professional agency is to convert uncertain compliance costs into predictable service fees.Zhongshen provides not only customs declaration operations,but also a complete set of solutions covering the entire supply chain.From overseas supplier qualification review,trade clause design,to domestic label compliance consulting and warehousing and logistics connection,each link is embedded with risk control nodes.This full-process embedded service model allows importers to focus on market development and channel construction,and hand over complex customs clearance matters to professional teams.
