Full Process Analysis and Key Compliance Points of Tianjin Customs Clearance Agency for Food Imported from Japan

Regulatory Environment and Practical Difficulties of Japanese Food Import at Tianjin Port

In early 2026,the reefer container yard in Beijiang Port Area of Tianjin Port welcomes the peak season of Japanese food import again.From Hokkaido scallops to Kyushu matcha powder,from Kanto sauces to Kansai instant noodles,there is a reality behind these goods: Japanese food import is not a simple transaction and transportation,but a compliance marathon running through the supply chain.Language barriers,standard differences,and upgraded quarantine,any problem in any link may lead to cargo detention,soaring costs,and even the risk of return shipment.

Beitang Inspection and Quarantine Department under Tianjin Customs implemented more detailed classified supervision on Japanese food in 2026.For high-risk categories such as aquatic products,dairy products and infant supplementary food,in addition to the conventional animal and plant quarantine certificate,specific component test reports issued by Japan’s Ministry of Agriculture,Forestry and Fisheries are also required.For alcoholic beverages such as sake and shochu,the customs will focus on verifying whether the use of additives complies with China’s GB 2760 Standard,especially some sweeteners and preservatives allowed in Japan may be prohibited in China.Radioactive substance testing remains a sensitive item.Although the Japanese government provides official testing certificates,Tianjin Port Customs still conducts random inspection at a proportion of 10% to test the content of Cesium-137 and Iodine-131.

Zhongshen’s position in this chain is not a simple document transmitter,but a converter that transforms the 20 years of foreign trade operation experience of the Shanghai headquarters into practical capabilities at Tianjin Port.Our team is stationed in Binhai New Area,docking with Tianjin Customs,Tianjin Inspection and Quarantine Bureau,and port operators,and integrates six core links: customs declaration and inspection,international transportation,warehouse management,foreign exchange receipt and payment,foreign exchange settlement and purchase,and export tax refund into an executable plan.

Document Pre-audit: Lock in Compliance Risks Before Cargo Departure

The documents provided by Japanese exporters are usually issued in accordance with the format of Japan’s Ministry of Agriculture,Forestry and Fisheries,which has表述 differences from the import food access list required by the General Administration of Customs of China.The revised Regulations on the Administration of Registration of Overseas Manufacturers of Imported Food implemented in March 2026 has stricter verification of factory registration numbers for high-risk categories such as aquatic products,dairy products and infant supplementary food.Zhongshen’s operation practice is to start pre-audit before the cargo departs: check whether the manufacturer registration number provided by the Japanese side is in the valid list of China Customs CIFER System,check whether the product ingredient list contains unapproved new resource food ingredients,and verify whether the shelf life marking method on the original Japanese label meets the conversion requirements of GB 7718 General Rules for Labels of Prepackaged Food.

Last summer,when Manager Li handled a batch of sauces imported from Osaka,he found that the ingredient list provided by the Japanese side contained "bonito extract".According to the latest Measures for the Supervision and Administration of Inspection and Quarantine of Imported Aquatic Products issued in 2026,bonito extract belongs to animal-derived non-edible products,which requires an additional risk substance assessment report.We immediately launched the emergency plan,requiring the Japanese side to supplement the histamine content test report issued by the official Japanese laboratory before the cargo is loaded,and adjust the wording of "natural extract" on the original label to the compliant Chinese marking of "bonito extract".This action avoided the risk of cargo detention for testing due to unclear ingredient declaration after arrival at the port.

Port Customs Declaration: Accurate Classification and Price Declaration Control

The core of customs declaration for Japanese food at Tianjin Port lies in accurate classification and reasonable pricing.Under the RCEP Agreement in 2026,commodities such as Japanese sake and green tea enjoy tariff reduction,but the format of the certificate of origin must be completely consistent with the customs filing template.Zhongshen’s customs declaration team will obtain the cargo manifest information in advance,complete the pre-entry 24 hours before the ship arrives at the port,and focus on three key nodes: first,commodity code classification,to avoid misclassifying sauces into the sauce category leading to tax rate differences; second,price declaration,referring to the FOB guide price published by the Japan External Trade Organization in the same period to prevent the risk of customs valuation; third,supervision document matching,for example,the official Japanese health certificate attached to imported aquatic products must be issued within 5 working days after the ship sets sail,otherwise it will be deemed invalid.

In actual operation,we encountered a batch of Japanese ready-to-eat rice imported by Mr.Fang’s company.When reviewing the documents,the customs considered that the declared price was lower than the average market level,triggering a price query.Zhongshen’s customs declarant immediately retrieved the export declaration data of similar Japanese products in the first quarter of 2026,combined with the composition of freight and insurance premiums,and submitted a detailed cost breakdown statement to the customs.At the same time,we provided supporting materials such as the sales contract of the Japanese factory and payment vouchers,and finally the customs accepted the original declared price,and the whole processing cycle was compressed to 3 working days.

Commodity Inspection: Sampling Testing and Label Rectification

Beitang Inspection and Quarantine Department under Tianjin Customs maintained an inspection rate of about 15% for Japanese food in 2026,while the random inspection proportion for high-risk products increased to 30%.The inspection focuses on three aspects: microbial overlimit,radioactive substance testing and label compliance.Zhongshen’s inspection specialist will prepare three sets of materials in advance: one set of original documents with the cargo,one set for future reference,and one set of electronic version uploaded to the customs e-CIQ System in advance.For goods that need to be sampled for testing,we coordinate with three qualified laboratories designated by Tianjin Port to ensure that the samples are transferred within 48 hours,so as to avoid additional reefer demurrage charges in the port area.

Label problems are high-frequency pain points for Japanese food import.In 2026,Tianjin Customs has extremely strict review on the corresponding relationship between the original Japanese label and the Chinese back label,especially the conversion of nutrition facts table,the marking of allergen information,and the conversion of shelf life format.Zhongshen’s practice is to complete the design and filing of Chinese labels before the cargo arrives at the port,and generate standard formats using the label review system recognized by the customs.For the unique "best before date" marking in Japan,we will convert it into the "expiry date" format familiar to domestic consumers according to the mode of production date plus shelf life,and clearly mark the storage conditions on the label.

Typical Case: Emergency Handling of Functional Beverage Ingredient Dispute

Last autumn,the company where Mr.Fang works imported a batch of functional beverages containing collagen peptide from Japan for the first time.After the cargo arrived at the port,the customs considered that "shark cartilage extract" in the product ingredients belongs to the category of new resource food,and required the access approval of the National Health Commission of China.Mr.Fang only had the product description from the Japanese side,and was completely unaware of the domestic regulatory requirements.After taking over the case,Manager Li of Zhongshen first checked the 2026 edition of the new resource food catalog,and confirmed that shark cartilage extract was not in the approved list.Then we launched the emergency plan: contacted the Japanese side to change the formula,adjusted the disputed ingredient to approved bovine bone collagen,and coordinated the port warehouse to temporarily store the original cargo to avoid return shipment.The whole processing cycle was controlled within 12 working days,saving nearly 400,000 yuan of logistics cost compared with direct return shipment.

This case exposes the typical risk of Japanese food import: the innovative application of ingredients by the Japanese side may touch the domestic regulatory red line.Zhongshen’s value lies in that we are not only familiar with Chinese regulations,but also understand the R&D habits of Japanese enterprises,and can find a conversion space between the regulatory systems of the two countries.We have established an internal database that includes all customs judgment results of Japanese food ingredients since 2026.When encountering new ingredients,we can quickly compare historical cases and give prediction opinions.

Warehousing and Follow-up Services: Port Temporary Storage and Foreign Exchange Settlement

Japanese food has strict temperature control requirements,especially for fresh aquatic products and dairy products.During the high temperature period in summer at Tianjin Port,the daily power connection fee for reefer containers is as high as 800 yuan.Zhongshen has signed annual agreements with three reefer container yards in Beijiang Port Area,which can obtain priority power connection right and fee discount for customers.For goods that need temporary storage,we will dynamically adjust the storage plan according to the customs inspection progress to avoid unnecessary container detention charges.

After the cargo is released,our service extends to foreign exchange receipt and payment and export tax refund.In 2026,the State Administration of Foreign Exchange implemented stricter directory management for trade foreign exchange receipts and payments.Zhongshen’s financial team will assist customers in completing the declaration of the foreign exchange monitoring system to ensure that the payment for goods is consistent with the amount on the customs declaration form.For Japanese food that meets the tax refund conditions,we prepare value-added tax invoices,tax refund copy of customs declaration form and other materials in advance,and submit the application through the electronic tax bureau.Usually,the tax refund can be received within 10 working days.

Comprehensive Balance of Cost and Time Efficiency

The overall time limit for Japanese food import at Tianjin Port,from the ship’s arrival to the cargo pick-up,normally takes 5-7 working days.If customs inspection or laboratory testing is encountered,the cycle may be extended to 15 working days.Zhongshen can shorten the customs clearance time of normal goods to 3-4 working days through pre-document pre-audit and pre-entry.For high-risk products,we communicate with the customs risk department in advance to strive to eliminate the control instructions before the cargo arrives at the port and reduce the inspection probability.

Enterprise Self-inspection Checklist and Agency Intervention Timing

For enterprises planning to import food from Japan,we recommend introducing agency participation before the contract is signed.Zhongshen provides a self-inspection checklist to help customers avoid common mistakes in the procurement process:

• Confirm whether the Japanese manufacturer is registered in the China Customs CIFER System and whether the registration status is valid
• Check the product ingredient list,especially whether functional ingredients belong to the new resource food or the catalog of substances that are both food and traditional Chinese medicine
• Check the shelf life marking method of the original Japanese label,and design the Chinese back label that meets the national standards in advance
• Evaluate the product risk level,and reserve 10-15 working days of customs clearance time for high-risk categories
• Prepare a complete trade document chain,including contract,invoice,packing list,bill of lading,certificate of origin,health certificate
• Understand the applicable conditions of tariff preferences under the RCEP Agreement to ensure that the format of the certificate of origin is compliant

The best time for agency intervention is when the Japanese cargo is ready and not yet loaded.Zhongshen can complete document pre-audit,label filing and price pre-audit at this stage,and solve the problems before the cargo is transported.Once the cargo arrives at the port,if problems are found,the processing cost and difficulty will increase exponentially.

Future Trends and Countermeasures for Japanese Food Import at Tianjin Port

In the second half of 2026,Tianjin Port plans to launch an intelligent document review system to implement AI-assisted review of customs declaration forms for Japanese food,which means higher requirements for the accuracy of declared data.Zhongshen is docking with the system developer to adapt the data interface in advance to ensure that customers’ goods can enjoy the fast channel.At the same time,the customs’ requirements for the traceability system of imported food are also upgrading,and it may be required to provide full-chain traceability information from the Japanese raw material origin to the finished product delivery in the future.

For Japanese importers,choosing an agent that is familiar with the characteristics of Tianjin Port,understands the habits of the Japanese supply chain,and has full-process service capabilities is no longer an option,but a necessity.Zhongshen’s 20 years of accumulated experience is reflected in the verification of each document,each customs communication,and each round of risk prediction.Our goal is to let customers’ goods arrive at the warehouse at predictable cost and controllable time under the premise of compliance.
