Dalian Port Import Customs Declaration Agency: Complete Operation Guide from Documents to Release

I.Background and Operational Difficulties of Import Cargo Supervision at Dalian Port

As a Northeast Asian international shipping hub,Dalian Port saw continuous growth in container throughput in 2026,maintaining top-ranked route density for Japan and South Korea in China.Precision equipment and electronic components imported from Tokyo,Osaka,Busan,and Incheon,timber and mineral products entering via Vladivostok,and agricultural goods transshipped from Southeast Asia form the core import cargo portfolio of Dalian Port.This cargo structure brings specific operational difficulties: goods from Japan and South Korea generally involve technical trade barriers such as CCC certification and radio type approval; Russian logs and grain products require official plant quarantine certificates,with discrepancies between fumigation treatment standards and domestic requirements; transshipment cargo has long document chains and complex origin determination.

When Mr.Qiu imported a batch of precision measuring instruments from Japan last year,he encountered a software encryption module attached to the equipment,which required both a commercial password import license and triggered dual-use item control review.Such complex regulatory requirements often leave inexperienced enterprises stuck after cargo arrives at the port,incurring high container detention fees and terminal storage fees.What’s more troublesome is that Dalian Port launched a new generation of inspection management system in 2026,with dynamically adjusted rules for manual document review and machine inspection control.Disputes over HS code classification,questions about dutiable value,and abnormal inspection and quarantine issues account for over 70% of total document returns.

II.Core Role of Zhongshen in Import Agency at Dalian Port

Zhongshen has stationed teams at two core port areas: Dayao Bay and Dalian Bay,and has established regular communication mechanisms with the Customs Comprehensive Business Section,Inspection Section,and Commodity Inspection and Food Inspection Section.This on-site physical advantage allows hidden risk points such as encryption modules,used mechanical and electrical attributes,and hazardous chemical components to be identified during the document pre-review stage.In Mr.Qiu’s project,Zhongshen intervened before the Japanese side loaded the cargo,guiding the supplier to declare the software module and hardware equipment separately: the hardware was declared as an ordinary measuring instrument,and the software module applied for a password product import license separately.The overall clearance period was shortened from the estimated 45 days to 18 days.

The core value of agency services lies in pre-emptive compliance consulting.Zhongshen has established a regulatory element database for common import commodities at Dalian Port,covering access conditions,regulatory documents,and inspection key points corresponding to over 2,000 HS codes.When a customer consults about importing cosmetic semi-finished products from South Korea,the system will automatically prompt that the "Record Certificate for Imported Non-Special Cosmetics",full ingredient ratio table,microbial and heavy metal test report,and the label review process designated by the drug supervision department of Dalian Port are required.This predictive ability avoids the passive situation of discovering missing documents only after the cargo arrives at the port.

III.Step-by-Step Breakdown of the Full Import Customs Declaration Process at Dalian Port

1.Document Pre-Review and Compliance Assessment

Document consistency is the first hurdle in clearance.Zhongshen requires customers to provide five basic documents: original contract,invoice,packing list,bill of lading,and certificate of origin,before launching a three-level review mechanism.The first review checks whether the goods name,specification model,quantity,unit price match the declaration elements; the second review verifies the validity of regulatory documents,such as whether the CCC certificate is within validity period,whether the issuing authority is authorized by the CNCA,and whether the product model covers the imported goods; the third review assesses special risks,including whether it involves solid waste attribute identification,whether it is listed in the used mechanical and electrical products catalogue,and whether it contains endangered species components.

Based on the import characteristics of Dalian Port,Zhongshen has compiled a list of high-frequency issues：

• Operation manuals and installation discs attached to imported equipment from Japan and South Korea must be declared separately as software products,and cannot be included in the total equipment price
• Original Plant Quarantine Certificate is required for Russian timber,and the fumigant concentration,treatment temperature,and duration indicated on the certificate must comply with GB/T 27784 standard
• For US-origin goods transshipped through South Korea,a Certificate of No Further Processing issued by US Customs must be provided when applying for preferential tariff rates
• For imported food contact materials,in addition to conventional documents,a conformity declaration and migration test report must be additionally provided

When Mr.Qiu imported the measuring instruments,Zhongshen discovered during the pre-review stage that the production date marked on the equipment nameplate was June 2023,which falls under the category of used mechanical and electrical products according to the Measures for the Supervision and Administration of Imported Used Mechanical and Electrical Products,and an "Import Record for Used Mechanical and Electrical Products" is required.The team immediately guided the Japanese side to provide equipment operation manuals,maintenance records,and residual value assessment reports,and submitted the record application to Dalian Commodity Inspection Bureau before the cargo departed,avoiding the dilemma of being unable to declare upon arrival at the port.

2.Port Customs Declaration and Tax Accounting

The core of the customs declaration process is HS code classification and dutiable value declaration.Dalian Port Customs strictly reviews prices for three major categories of goods: machinery,chemicals,and food,and focuses on monitoring under-declared prices in 2026.Zhongshen adopts a "benchmark price + floating factor" model,referring to the transaction prices of similar goods at Dalian Port in the same period,international futures market trends,and exchange rate fluctuation coefficients,to formulate a reasonable declaration price range for customers.When declaring precision measuring instruments for Mr.Qiu once,the customs system triggered price risk parameters.Zhongshen submitted technical materials such as the Japanese manufacturer’s original sales invoice,equipment configuration list,and function description within 24 hours,proving that the high unit price was due to nanometer-level measurement accuracy rather than underreported price,and finally obtained customs approval.

Tax accounting needs to consider multiple variables.In addition to tariffs and value-added tax,Dalian Port levies anti-dumping duties and consumption tax on specific commodities.Zhongshen has developed a tax simulation calculator,which can automatically output tax details after entering the HS code,declared price,and origin.Taking a 2.5-liter gasoline engine imported from Japan as an example,the tariff rate is 8%,VAT is 13%,consumption tax is 9%,and the comprehensive tax burden reaches 32.6%.If the engine complies with the RCEP origin standards,the tariff can be gradually reduced to zero,but a back-to-back certificate of origin issued by Japanese Customs must be provided.

3.Commodity Inspection and Release Handling

The inspection rate of statutory inspection goods at Dalian Port has long remained above 30%.Zhongshen’s on-site personnel arrive at the inspection site within 15 minutes after receiving the inspection instruction,and assist customs officers in unpacking,unboxing,and sorting goods.Key inspection points include: whether the product name and specifications match,whether contraband is smuggled,whether wooden packaging is marked with IPPC,and whether dangerous goods are labeled with GHS labels.In 2026,Dalian Port implemented a "batch inspection" policy for imported foods,extending the microbial and heavy metal test cycle to 7 working days.Zhongshen compressed the overall waiting time by 30% through methods such as appointment inspection and off-peak testing.

Handling inspection abnormalities tests the responsiveness of agency institutions.There was once a batch of flour imported from Russia,and customs sampling found that vomit toxin exceeded the standard,requiring the entire batch to be returned or destroyed.Zhongshen quickly activated the emergency plan: first verify whether the sampling process is compliant and confirm the representativeness of the sample; then contact the Russian supplier to obtain the test report of the same batch of goods in the exporting country,proving that the toxin content complies with Russian standards but is lower than Chinese standards; finally coordinate with Dalian Customs to conduct a retest and apply for technical rectification,removing moldy particles through physical sorting,allowing the goods to be released conditionally,saving the customer nearly 2 million yuan in losses.

IV.Practical Case: Mr.Qiu’s Mechanical Equipment Import Project

Mr.Qiu’s company imported 5 precision CNC grinding machines from Japan,with a value of 38 million yen,planned for the production line of the new factory in Dalian Development Zone.When Zhongshen intervened,the Japanese side had completed packaging and was ready to load the cargo.The project team immediately launched a risk scan and found three potential issues: the equipment falls under the used mechanical and electrical products catalogue; the attached measuring software worth 2 million yen is subject to password product control; and the wooden packaging is not marked with IPPC.

Zhongshen handled three tasks in parallel: First,guide the Japanese side to supplement the equipment’s maintenance records of the past three years and residual value assessment report,apply for used mechanical and electrical product record to Dalian Commodity Inspection Bureau,obtain the "Pre-Shipment Inspection Notice for Imported Used Mechanical and Electrical Products",and entrust the Japanese CCIC institution to conduct pre-shipment inspection; Second,separate the software module from the total equipment price,separately submit the application materials for "Commercial Password Product Import License" to the State Cryptography Administration,and prepare technical documentation to demonstrate that the software is only used for equipment debugging and does not involve encryption algorithm export; Third,coordinate with the Japanese side to replace the wooden packaging that complies with ISPM 15 standards and add IPPC markings.

After the cargo arrived at Dayao Bay Port,Zhongshen submitted the full set of documents including the used mechanical and electrical product record certificate,pre-shipment inspection report,password product import license,and IPPC marking photos to customs in advance.After review,customs granted a green release channel and exempted from inspection.From the berthing of the ship to the release of the cargo,the total time taken was 4 working days,saving 11 days compared to conventional operations,avoiding a total of about 48,000 yuan in container detention fees and storage fees.Mr.Qiu later commented that the value of Zhongshen lies not only in customs declaration operations,but also in pre-emptive risk identification and systematic solution design.

V.2026 Import Supervision Trends at Dalian Port and Countermeasures

In 2026,Dalian Port Customs promoted the upgrade of "smart supervision",introduced an AI-assisted document review system,implemented algorithm pre-review for HS code classification,price declaration,and origin determination,and increased the automatic interception rate of abnormal documents to 45%.At the same time,the commodity inspection department has strengthened traceability management of high-risk commodities,established a quality and safety information traceability platform for imported food,cosmetics,and medical devices,and required enterprises to provide the registration number of overseas manufacturers,product batch number,and logistics chain information.

Zhongshen recommends that enterprises take three countermeasures: First,establish supplier compliance files,require overseas shippers to provide complete qualification certificates,product technical documents,and quality test reports,and agree on liability for breach of contract for inconsistent documents in the contract; Second,use Zhongshen’s simulation declaration system to conduct a full-process drill before the cargo is shipped to identify potential risk points; Third,purchase import cargo insurance and clearance delay insurance for high-value,high-tech goods to transfer force majeure risks.

As an open gateway to Northeast Asia,Dalian Port’s regulatory rules reflect both national unified requirements and regional characteristics.The localized service capability formed by Zhongshen’s 20 years of deep cultivation is reflected in the accurate interpretation of Japan and South Korea’s technical trade barriers,in-depth understanding of Russian quarantine standards,and extreme familiarity with port operation procedures.This capability translates into actual benefits for customers: the average clearance time is shortened by 40%,the document return rate is controlled below 2%,and compliance costs are reduced by 15% to 20%.For enterprises planning to import goods through Dalian Port,choosing an agency with deep localized experience is a key decision to ensure supply chain stability and avoid hidden risks.
