Practical Challenges of Importing Russian Far East Aquatic Products via Dalian Port

In the first quarter of 2026,the total volume of Russian king crab and cod imported via general trade in Dalian Customs District increased by 23% year on year,but the return rate caused by inconsistent documents and unqualified quarantine also rose to 5.8% in the same period.In a case handled by Supervisor Wan in March,a batch of frozen cod imported by a trading company from Vladivostok Port was detained by Dayao Bay Customs for 11 full days because the certificate of origin did not indicate the fishing area code,resulting in total container detention and cold storage fees exceeding 180,000 yuan.Such losses are not isolated cases.Many enterprises believe that general trade import is simply "customs declaration and tax payment",but ignore the unique rigid requirements for aquatic products such as the Entry Animal and Plant Quarantine Permit,radioactive substance testing,and cold chain transportation temperature record trail.Dalian Port implements differentiated supervision on aquatic products from source countries including Russia,Norway,and Chile.Details such as incorrect HS code classification,missing signature of the veterinary officer on the sanitary certificate,and failure to mark the fishing vessel name on the outer packaging label may trigger inspection or even destruction procedures.

The 15-member team of Zhongshen based in Dalian receives dynamic instructions from three supervision zones: Dayao Bay,Beiliang Port,and Lüshun New Port synchronously every day.Manager Wen mentioned that in 2026,the General Administration of Customs added a new regulation for imported aquatic products: "a risk analysis report is required if the temperature fluctuation exceeds 3 degrees Celsius during transportation".This seemingly ordinary notice actually requires enterprises to confirm with the shipping carrier whether the data interface of the reefer container can connect with the customs system at the booking stage.Many importers do not realize until the goods arrive at the port that they cannot obtain the temperature record data on board for the goods purchased under FOB terms at all,resulting in failure to submit compliant documents during customs declaration.

Document Pre-audit Stage: Resolve Problems Before Cargo Loading

Zhongshen’s service starts the moment it receives the scanned copies from overseas suppliers.Supervisor Wan’s team will establish an exclusive file,and verify the validity of the production registration number against the *2026 Access List of Overseas Aquatic Product Manufacturers*.A total of 37 fishing vessel processing enterprises in Russia had their qualifications suspended at the end of 2025,but some overseas suppliers still use the old version of the list for quotation.If not identified in advance,the goods will face return shipment immediately upon arrival at the port.

The pre-audit checklist covers 23 core documents,focusing on three types of high-risk items:

• Sanitary certificate: It must show the official seal of the Federal Service for Veterinary and Phytosanitary Supervision of the Russian Federation,the name and registration number of the signing veterinary officer,and the date of issuance of the certificate shall not exceed 7 days from the shipment date.Since April 2026,the FAO code of the fishing area must also be added to the certificate,and the inspection rate caused by the absence of this item accounts for 34% of the total problems.
• Certificate of origin: GSP Certificate of Origin FORM A is no longer applicable to Russian aquatic products,and a general certificate of origin or a special origin declaration under the China-Russia Free Trade Agreement must be provided.Manager Wen once handled a batch of king crab worth 2 million yuan.Due to the overseas agent’s misuse of FORM A,the tariff soared from 5% to 14%,resulting in a direct tax loss of 180,000 yuan.
• Fishing certificate: For wild-caught fish,a copy of the fishing license issued by the Russian Federal Agency for Fisheries must be provided to prove that the fishing volume does not exceed the annual quota.The cod quota in the Russian Far East was cut by 12% in 2026 compared with 2025,and documents for over-quota fishing from many suppliers were directly judged invalid during customs online verification.

The pre-audit cycle usually takes 3-5 working days,and Zhongshen will conduct video calls with overseas suppliers to check document details page by page.Supervisor Wan intercepted a batch of "problematic goods" in February 2026: the veterinary officer’s signature on the sanitary certificate provided by the supplier was printed rather than handwritten,which was judged as an invalid certificate during comparison by the customs system.After discovering this problem in advance,the supplier was immediately required to reissue the certificate,avoiding the risk of port detention after the goods arrived.

Port Customs Declaration Link: Accurate Classification and Tariff Application

The HS code classification dispute rate for aquatic products at Dalian Port remains high,especially for products with ambiguous processing method definitions.For example,should frozen cod that is headed,gutted and cut into sections be classified under 03036300 (frozen cod,7% tariff) or 16041990 (prepared or preserved cod,12% tariff)?The classification difference directly leads to a 5 percentage point tariff difference.Zhongshen’s customs declaration team holds the pre-classification qualification issued by the General Administration of Customs,and will submit a classification inquiry letter to the Dalian Customs Tariff Office before declaration to obtain official confirmation opinions.

In 2026,the customs launched the "intelligent document review" system,which has extremely high requirements for the completeness of declaration elements.Taking imported Russian king crab as an example,the declaration elements need to be specific to: scientific name (Paralithodes camtschaticus),specification (200-300g per piece),packing specification (10kg per box),whether it is live fresh,fishing method (pot caught or trawling),transportation method (air freight or sea freight).Manager Wen pointed out that many enterprises omit the "fishing method",and the system directly judges the declaration as incomplete and transfers it to the manual document review channel,extending the customs clearance time by 2-3 days.

Zhongshen’s customs declaration system is directly connected with the customs H2010 system,and the declaration data will go through three levels of logic verification before being sent.When Supervisor Wan handled a batch of Norwegian salmon imports in March 2026,the system prompted "the certificate of origin number does not match the customs registration database".After verification,it was found that the overseas agent mistakenly entered the letter "O" in the certificate number as the number "0",and the goods were released smoothly after correction.Such detailed errors are easily overlooked in manual review,but the intelligent document review system has a 100% interception rate.

Commodity Inspection and Release: Cold Chain Supervision and Laboratory Testing

The core risks of aquatic product import are concentrated in the commodity inspection link.The Animal and Plant Inspection Division of Dayao Bay Customs,subordinate to Dalian Customs,implements strict supervision of "inspecting every batch,measuring temperature of every item" for imported aquatic products.Zhongshen’s on-site personnel will arrive at the inspection platform 2 hours before the ship berths,and coordinate with the terminal dispatcher to arrange inspection berths on priority.

In 2026,the customs launched the new "three-document cross-verification" requirement for cold chain supervision: the data of the customs declaration form,manifest,and temperature record sheet must be completely consistent.Manager Wen explained that many importers only focus on the customs declaration form and manifest,but ignore the temperature record sheet.The temperature data of the reefer container during transportation is uploaded to the customs cold chain supervision platform in real time through the shipping carrier’s GPS system.If a temperature exceeding the standard alarm occurs,the goods will be directly transferred to the quarantine warehouse,waiting for laboratory testing.

The laboratory testing cycle is usually 5-7 working days,and the testing items include: total volatile basic nitrogen,histamine,heavy metals (lead,cadmium,mercury),veterinary drug residues (chloramphenicol,nitrofuran),and radioactive substance cesium-137.Zhongshen has established a green channel for sample submission with the Dalian Customs Technology Center,which can shorten the testing cycle to 3 working days.For a batch of Russian cod handled by Supervisor Wan in April 2026,the customs judged it unqualified due to 0.2mg/100g excess of total volatile basic nitrogen.Zhongshen immediately launched the emergency plan,assisted the customer in handling return shipment procedures,and contacted the Russian supplier for compensation,finally recovering 70% of the payment loss for the customer.

Case Review: 72-hour Crisis Handling of a Russian King Crab Import

In May 2026,a catering group entrusted Zhongshen to act as the agent for importing a batch of Russian live fresh king crab worth 4.5 million yuan,totaling 3 tons,packed in 12 special seawater tanks.The goods were transported by air from Vladivostok to Dalian Zhoushuizi International Airport,and were expected to arrive at 2 a.m.Supervisor Wan received an email from the overseas agent 6 hours before the flight took off,and found that the fishing date on the sanitary certificate was 3 days later than the actual shipment date,which meant the certificate issuance time was logically wrong,and the customs would judge it as a fraudulent document.

Zhongshen launched the 72-hour emergency response:

• 1st hour: Supervisor Wan directly contacted the Russian supplier,requested immediate reissuance of the correct certificate,and simultaneously contacted the Russian veterinary officer’s office to explain the situation and strive for expedited processing.
• 6th hour: The scanned copy of the new certificate arrived.After internal review by Zhongshen confirmed no errors,the document was pre-entered into the customs system in advance,and the *Emergency Customs Clearance Application* was submitted.
• 12th hour: The goods arrived at Dalian Airport.The customs agreed to release the goods first and supplement the original certificate later,and Zhongshen paid a deposit of 1.2 million yuan.
• 48th hour: The original certificate was delivered to Dalian via international express.After the customs verified it was correct,the deposit was refunded.
• 72nd hour: The goods were successfully delivered to the temporary rearing pond designated by the customer,with zero mortality and zero loss.

Manager Wen reviewed the case afterwards: if following the conventional process of waiting for the original certificate to arrive before customs declaration,the king crab would be kept in the customs supervision warehouse,resulting in 24,000 yuan of storage fees per day,and the survival rate would drop by 5% per day.Zhongshen’s emergency mechanism saved the customer at least 150,000 yuan of additional costs and ensured the quality of the goods.

Service Value of Zhongshen: From Cost Center to Profit Guarantee

Many import enterprises regard the customs declaration agency fee as a cost expenditure,but Zhongshen’s service is essentially a risk hedging tool.According to 2026 customs audit data,the average inspection rate of general trade imported aquatic products at Dalian Port is 28%,while the inspection rate of goods represented by Zhongshen is controlled below 9%.This benefits from three core capabilities: preliminary document pre-audit,accurate HS classification,and standardized label audit.

Supervisor Wan calculated: for an aquatic product trading company with an annual import volume of 50 million yuan,if it operates by itself,the annual average loss caused by document errors,classification mistakes,and unqualified quarantine is about 1.2 million yuan.After entrusting Zhongshen,the agency fee expenditure is about 350,000 yuan,but the direct losses avoided exceed 800,000 yuan,with a net income of 450,000 yuan.More importantly,the stable customs clearance efficiency enables the enterprise to meet the just-in-time procurement needs of high-end catering customers,and the annual turnover increases by 40% as a result.

Zhongshen has a 3,000-square-meter bonded cold storage in Dalian,equipped with -60℃ ultra-low temperature freezing capacity,which can provide customers with value-added services such as temporary storage,sorting,labeling,and distribution after the goods arrive at the port.Manager Wen emphasized that in 2026,the customs launched the "two-stage access" reform,and goods release does not equal to customs clearance completion.Follow-up supervision requires enterprises to establish complete import records and sales ledgers.Zhongshen’s ERP system can automatically generate electronic account books that meet the requirements of customs audit for customers,avoiding follow-up supervision risks.

From document pre-audit to port coordination,from commodity inspection response to crisis handling,Zhongshen has transformed 20 years of practical experience into replicable service modules.The import environment at Dalian Port is becoming more complex in 2026,but professional agency services enable enterprises to focus on upstream supply chain procurement and downstream sales under the premise of compliance,instead of being entangled in the trivial details of the customs clearance link.Supervisor Wan finally mentioned that their goal is not simply "customs clearance",but to build full-process certainty for customers from procurement negotiation to terminal delivery.
