5 Core Stages of Japan Import and Export Customs Clearance

For foreign trade enterprises engaged in Sino-Japan trade,customs clearance is an inevitable key link -- incomplete documents may lead to cargo detention,errors in tariff calculation affect profits,and even cause delivery delay due to policy updates.In 2026,Japan has introduced new adjustments to customs clearance requirements for electronic documents and environmental protection products,and it is difficult for many enterprises to keep up with the pace only by their internal teams.As a foreign trade agency with 20 years of deep roots in Shanghai,Zhongshen decomposes the Japan import and export customs clearance process into 5 core stages based on years of service experience to help enterprises avoid detours.

1.Preliminary Preparation: "Pre-audit" of Documents and Qualifications

Stage Objective: Ensure all documents meet the requirements of Japan Customs and avoid rework that delays shipping schedule.

Key Actions:

• Verify import and export qualifications (Japanese importers need to provide "Importer Number",we can assist connect with compliant agency if no qualification is available)
• Organize basic documents (packing list,commercial invoice,bill of lading,certificate of origin,etc.which need to comply with format specifications of Japan Customs)
• Confirm commodity HS code (Japan Customs has strict code classification,which needs to accurately match the actual attributes of the commodity)
• Check mandatory certification (such as PSE certification for electrical appliances,food hygiene permit,Japan added remote certification requirements for some electronic products in 2026)

Common Problems:

• Incorrect format of certificate of origin (Japan only recognizes FORM A issued by commodity inspection authority,some enterprises mistakenly choose other formats leading to application rejection)
• No IPPC mark on wooden packaging (Japan upgraded wooden packaging quarantine in 2026,cargo without mark will be required for on-site fumigation)
• HS code classification deviation (such as misclassifying smart home appliances as ordinary home appliances,leading to wrong application of tariff rate)

Role of Zhongshen: Manager Qian is in charge of customer docking,pre-audits all documents 1-2 weeks in advance,verifies the validity of electronic documents required by Japan Customs in 2026,reminds customers to supplement traceable electronic versions; if the customer does not have Japanese importer qualification,we can assist connect with compliant importer with "Importer Number" to avoid declaration failure caused by qualification issues.

2.Customs Declaration: System Submission and Data Verification

Stage Objective: Complete one-time successful declaration through Japan Customs "NACCS" system,avoid rejection and re-declaration.

Key Actions:

• Electronic declaration (upload all documents through NACCS system,some documents are required to be uploaded to the database of Japan External Trade Organization simultaneously in 2026)
• Tariff / Consumption Tax declaration (Japan tariff calculation needs to combine CIF price,tariff schedule and additional tax,some environmental protection products can enjoy tariff reduction and exemption)
• Pre-classification confirmation (for complex commodities,communicate with the pre-classification department of Japan Customs in advance)

Common Problems:

• Deviation between declared value and market price (Japan Customs will refer to transaction price of similar commodities,deviation over 10% will be subject to spot check)
• Operation error in electronic declaration system (such as wrong HS code input,reversed order of document upload)
• Failure to declare additional tax (some commodities in Japan need to pay consumption tax and local consumption tax,with a total of about 10%)

Role of Zhongshen: Manager Niu is familiar with NACCS system operation,will double check HS code and declared value before declaration,has helped more than 30 enterprises avoid declaration rejection caused by system operation error since 2026; he can also estimate the amount of tariff and additional tax in advance according to commodity category,so that customers can clarify costs clearly.

3.Inspection and Release: On-site Coordination and Problem Handling

Stage Objective: Pass customs inspection quickly without delaying shipping schedule or flight.

Key Actions:

• Coordinate with customs inspection (such as checking consistency between commodities and documents by opening boxes,sampling for quality testing)
• Handle inspection problems (such as supplementing explanation for quantity discrepancy,on-site rectification for commodity labels that do not meet Japanese standards)
• Pay taxes and fees (tariff,consumption tax,etc.can be paid by Zhongshen on behalf of customers)

Common Problems:

• Vague ingredient labeling for food products (Japan requires food ingredients to be labeled with the specific name of additives in 2026)
• No Japanese instruction manual provided for electronic products (Japan Customs requires imported electronic products to be equipped with Japanese operation instructions)
• Insufficient response speed to inspection (enterprises do not arrange special personnel for on-site docking,leading to prolonged inspection time)

Role of Zhongshen: Mr.Geng is in charge of on-site coordination for inspection,prepares all required documents for inspection in advance.In 2026,he handled a case of vague food ingredient labeling for a customer,assisted in contacting a third-party testing institution to supplement the explanation on site,and avoided cargo detention; we also provide tariff payment agency service,so that customers do not need to queue on site for payment,saving 3-5 hours of waiting time.

4.Warehousing and Logistics Connection: From Supervised Area to Destination

Stage Objective: Deliver cargo smoothly from the customs supervised area to the customer’s designated warehouse or store.

Key Actions:

• Arrange customs supervised warehousing (if temporary storage is required,the Japanese bonded warehouse cooperated by Zhongshen can provide 7 days of free storage)
• Coordinate logistics transportation (dock with local Japanese trailer,sea/air freight agents to ensure smooth connection)
• Complete pickup procedures (customs release certificate and delivery order are required)

Common Problems:

• Cargo stranded at the port due to no pre-booking of warehousing (port congestion in Japan intensified in 2026,warehousing booking needs to be made 3 days in advance)
• Poor logistics connection (trailer is not arranged in time after the ship arrives at the port,resulting in container detention fee)
• Failure to report dangerous goods transportation in advance (Japan has strict requirements for dangerous goods transportation,special transportation permit needs to be applied in advance)

Role of Zhongshen: Zhongshen has cooperative Japanese bonded warehouses and can reserve space in advance; we can also dock with local Japanese logistics providers,helped customers solve the problem of trailer delay caused by port congestion in 2026,and ensured on-time delivery of cargo through alternative logistics routes.

5.After-sales Follow-up: Document Archiving and Problem Traceability

Stage Objective: Ensure all documents are traceable to cope with possible subsequent inspections.

Key Actions:

• Organize complete set of customs clearance documents (archive and store for more than 3 years to meet inspection requirements of Japan Customs)
• Follow up tariff refund (if it meets Japan’s tariff reduction and exemption policy for imported environmental protection equipment,we assist in handling the refund)
• Answer follow-up questions (such as customs clearance requirements for commodity re-export,interpretation of Japan Customs policy updates)

Common Problems:

• Improper preservation of documents leads to failure to provide materials for subsequent inspection (Japan Customs has the right to require enterprises to provide customs clearance documents within 3 years)
• Unfamiliar with Japan’s tariff refund process (some environmental protection products can enjoy 50% tariff reduction,which requires active application during declaration)

Role of Zhongshen: Ms.Ruan is in charge of document archiving,will back up all customs clearance documents electronically and notify customers; she helped a customer handle tariff refund for imported environmental protection equipment in 2026,saving about 2% of the cargo value in cost; we also provide customs clearance consulting for customers’ subsequent trade and interpret policy updates in a timely manner.
