# Full Process Analysis and Risk Avoidance Guide for Customs Clearance Agency of Japanese Imported Food Ingredients in Shenzhen

## Entry Barriers and Practical Difficulties of Importing Japanese Food Ingredients to Shenzhen

In the first quarter of 2026,the import volume of Japanese food at Shenzhen Port increased by 15% year-on-year,but the number of return and destruction cases also rose by 22% in the same period.Behind this figure is the reality that importers have insufficient understanding of the special regulatory requirements for Japanese food ingredients.Japanese food ingredients are mainly aquatic products,pre-packaged condiments and processed agricultural products,each of which has independent access directories and quarantine standards.Shenzhen Customs strictly enforces standards on Japanese label review,radioactive substance testing,cold chain transportation verification and other links,and enterprises often get stuck at three nodes when operating on their own: misjudgment of access qualification,inconsistent document format,and deviation in understanding of quarantine standards.

Zhongshen has been deeply engaged in import and export agency in Shanghai for 20 years,and the Japanese food ingredients cases it has handled cover three major categories: aquatic products,pre-packaged food and agricultural products.The team led by Supervisor Shen does not accept scattered customs declaration forms,but provides full-process custody from pre-shipment pre-audit to distribution after warehousing.Under this model,the abnormal customs clearance rate has been reduced from the industry average of 18% to less than 3%.For Shenzhen importers,choosing an agent partner familiar with port characteristics is essentially spending money to buy certainty and time.

## Document Pre-audit and Access Qualification Confirmation: Pre-review Determines Success or Failure

The first step of importing Japanese food ingredients is not to ship,but to confirm whether the product is in the access directory.In April 2026,the General Administration of Customs of China updated the Regulations on the Administration of Registration of Overseas Food Production Enterprises for Imported Food,requiring Japanese aquatic product enterprises to provide Chinese translation of HACCP certification.Manager Pei once handled a typical case: the customer planned to import scallop adductor from Hokkaido,Japan,but the health certificate provided by the Japanese side still used the 2025 old version format,and did not mark the fishing area code.Manager Pei found this problem in the pre-audit stage and asked the Japanese side to re-apply for the certificate,avoiding the risk of goods being returned due to inconsistent documents after arrival.

The list of documents to be prepared at this stage includes: the original health certificate issued by the Japanese official authority,the certificate of the production enterprise’s registration number in China,the product formula table (for pre-packaged food),and the qualified radioactive substance test certificate (for products from specific regions).The practice of Zhongshen is to establish a dynamic database,and track the policy changes of the regulatory authorities of China and Japan in real time.The document team led by Mr.Fan updates the Template Library of Japanese Quarantine Certificates for Food Exported to China every week,to ensure that every certificate received by the client meets the current port requirements.

The quarantine requirements vary greatly for different product categories,Zhongshen has compiled the latest comparison table for 2026:

| Product Category | Core Quarantine Certificate | Special Requirements (2026) | Common Mistakes |
| --- | --- | --- | --- |
| Frozen Aquatic Products | Official Japanese Health Certificate | Fishing Area Code + Chinese Translation of HACCP | Outdated Certificate Format |
| Pre-packaged Condiments | Composition Analysis Report | Chinese Allergen Labeling + Registration Number | No Pre-audit of Labels |
| Fresh Agricultural Products | Radioactive Substance Test Certificate | Origin Traceability QR Code | Expired Test Report |

## Port Customs Declaration and Tax Calculation: A Detail Battle on Price Assessment and Classification

Shenzhen Port has relatively strict price assessment standards for Japanese food ingredients,especially for high-end products such as Wagyu beef and tuna.In 2026,the customs launched the new Operating Procedures for Price Assessment of Imported Goods,which requires the provision of local purchase invoices in Japan,payment vouchers and logistics chain proof.When Manager Kang handled the import of Wagyu beef for a Japanese chain restaurant in Shenzhen,he found that the customer paid the payment through a Hong Kong offshore company,which resulted in unclear price composition.Manager Kang assisted the customer to sort out the complete capital flow proof,and submitted a situation statement to the customs,and finally taxed according to the actual transaction price,avoiding the risk of valuation and tax supplementary payment.

The difficulty of customs declaration lies in commodity classification.Japanese condiments often have complex ingredients and may involve multiple tax codes.President Qin of Zhongshen will intervene in advance and determine the most accurate HS code according to the proportion of product ingredients.For example,a certain brand of ramen soup contains soy sauce,mirin and fish extract.Different ingredient proportions determine whether it is classified under tax code 2103 or 2104,with a tax rate difference of 5 percentage points.Based on the percentage data in the composition analysis report,President Qin obtained a more favorable tax code for the customer,saving nearly 10,000 RMB in tax for a single shipment.

Another pitfall in tax calculation is the certificate of origin.Under the RCEP agreement,Japanese food exported to China enjoys tariff preferences,but the format of the certificate of origin must comply with the 2026 new version standard of the General Administration of Customs.Supervisor Shen’s team will review the draft certificate before shipment to ensure that every piece of information is consistent with the customs declaration,avoiding the inability to enjoy preferences due to minor differences after arrival.

## Commodity Inspection and Laboratory Testing: The Biggest Variable of Time Cost

The Food Inspection and Quarantine Technology Center of Shenzhen Customs covers four major categories of testing items for Japanese food ingredients: microorganisms,additives,heavy metals and radioactive substances.In 2026,a new item "verification of temperature records during cold chain transportation" was added,which requires the provision of full-process temperature control data from the Japanese factory to Shenzhen Port.Supervisor Shen’s team will guide customers to install temperature recorders that meet the requirements in advance,and ensure that the data format meets the reading standards of the commodity inspection system.

Testing cycle is the most concerned issue for importers.Through methods such as pre-scheduled inspection and expedited channels,Zhongshen reduces the conventional testing time from 7 working days to 4 working days.For fresh products that are urgently needed to be launched,the "inspection while releasing" mode can also be applied.Under the premise of providing a security deposit,you can pick up the goods first,and the guarantee will be lifted after the test result is qualified.

The specific contents of the testing items are as follows:

- Microbial testing: total colony count,coliform bacteria,pathogenic bacteria
- Additive screening: compliance of preservatives,pigments,sweeteners
- Heavy metal residue: lead,cadmium,mercury,inorganic arsenic
- Radioactive substances: Cesium-137,Iodine-131 (for specific regions)
- Cold chain verification: verification of completeness of full-process temperature records

Manager Pei specially reminds that in 2026,some products from Fukushima Prefecture,Japan have resumed export to China,but the radioactive substance testing standard is three times stricter than other regions.A customer once imported condiments from areas near Fukushima,and the entire batch was destroyed due to unqualified test because he did not inform the origin in advance.When accepting an order,Zhongshen will force customers to provide a certificate of origin accurate to the county level and enter it into the risk assessment system.

## Warehousing and Distribution: Label Affixing and the Last Mile

After passing the commodity inspection,the goods enter the bonded warehouse of Zhongshen in Shenzhen.What needs special attention here is that the Chinese label of Japanese pre-packaged food must be affixed before warehousing.In 2026,the State Administration for Market Regulation has more detailed requirements on the labels of imported food,requiring the labeling of allergen information,GMO identification (if applicable),and the registration number of the Japanese production enterprise.Zhongshen provides label review and printing services to ensure that every product is label-compliant before launch.

The label review team led by Mr.Fan found that Japanese manufacturers are used to marking eras like "Reiwa 8" on labels,but Chinese regulations require Gregorian date.A customer was once fined 50,000 RMB by the market supervision department due to the date format problem on the label.During the review,Zhongshen will force the Japanese side to provide Gregorian date marking,and clearly mark it on the Chinese label.

In the distribution link,Zhongshen provides two modes according to customer types: for large chain supermarkets,direct distribution to the central warehouse; for small Japanese restaurants,LCL distribution services are provided.The distribution plan designed by President Qin takes into account the characteristics of the goods.For example,frozen tuna requires -60ultra-low temperature transportation,Zhongshen will arrange special refrigerated trucks to avoid quality degradation of the goods in the last mile.

## Practical Case: 72-Hour Rescue of 800,000 RMB Octopus Slices Stranded at the Port

In February 2026,an importer in Shenzhen planned to import a batch of frozen octopus slices from Fukuoka,Japan,with a cargo value of about 800,000 RMB.After the goods arrived at the port,the sampling inspection by the commodity inspection department found that the production date format on the product packaging did not meet Chinese standards,and the registration number in China was not marked.When the customer contacted Zhongshen,the goods had been stranded at the port for 5 days,and the daily container detention fee and refrigeration fee were nearly 10,000 RMB.

After Supervisor Shen took over,he immediately launched an emergency plan: first,contact the Japanese manufacturer to re-make qualified Chinese labels and arrange air shipment to Shenzhen; second,coordinate with the commodity inspection department to allow on-site affixing to avoid returning the goods; third,Manager Pei applied to the customs to modify the customs declaration and supplement the registration number information.The entire processing process took 3 days,saving the customer the additional costs that would have been incurred if the goods continued to be stranded.

This case reveals that many importers do not update the regulations on Japanese food labels in time,and rely on the default packaging provided by foreign suppliers.When accepting an order,Zhongshen will force customers to provide label design draft for pre-audit,and intercept problems before shipment.Supervisor Shen concluded that the prevention cost is one tenth of the remediation cost,and pre-review is the core value of agency services.

## The Essence of Agency Service: Exchanging Professional Experience for Certainty

The chain of importing Japanese food ingredients to Shenzhen is long and has many nodes,each link has specific compliance requirements.The value of Zhongshen lies in integrating scattered regulatory requirements into an executable operation list,and changing post-remediation to pre-prevention.From document pre-audit to label affixing,from tax calculation to testing follow-up,the essence of agency service is to exchange professional experience for time and certainty.

In 2026,with the deepening implementation of the RCEP agreement,Sino-Japanese food trade ushers in new opportunities,but the general trend of stricter regulation will not change.As the primary port for Japanese food ingredients to enter the South China market,the law enforcement standards of customs and commodity inspection in Shenzhen will only become more and more precise.The challenge for importers is no longer whether they can import the goods,but whether they can control costs and improve turnover efficiency on the premise of compliance.

The database,case library and network accumulated by Zhongshen in 20 years constitute a risk firewall that is difficult for ordinary enterprises to replicate.Choosing such a partner means outsourcing non-core processes and focusing on sales channels and brand building.For the segmented track of Japanese food ingredients import,professional agency is not a cost,but an investment.
