Analysis on Core Operation Process of Japan Import Customs Clearance Agency
As a practical expert focusing on Japan import and export agency for 20 years,we often encounter situations where enterprises face cargo port detention due to insufficient understanding of customs clearance process.For example,a Japanese auto parts importer last year failed to confirm HS Code classification rules in advance,leading to wrong classification determined by customs during declaration,which resulted in 3 days of port detention after cargo arrival and nearly 50,000 RMB demurrage.Japan import customs clearance agency shall strictly follow the four-step core process of "pre-review - declaration - inspection - release",with risk points in each link to be avoided in advance.
1.Preparation Stage for Japanese Exporters
- Confirm HS Code of the goods: There are differences between the HS Code systems of Japanese Customs and Chinese Customs.For example,for the HS Code 30049090 (Japanese-made medical consumables),Chinese customs requires distinction between "pre-dosed" and "non-pre-dosed" in classification,and wrong classification will lead to abnormal declaration data.
- Certificate of Origin (FORM J): Note that from 2026,for agricultural products,aquatic products and other goods exported from Japan to China,FORM J certification must be handled at designated institutions under the Ministry of Agriculture,Forestry and Fisheries of Japan,to avoid queries from Chinese customs due to non-compliant non-originating component proportion.
- Selection of trade terms: FOB terms (the buyer is responsible for transportation and insurance) are recommended.Under EXW terms,extra communication cost for Japanese exporters to cooperate in customs clearance will be incurred.Zhongshitong once assisted a client in changing trade terms from EXW to FOB,which reduced customs clearance delay rate by 30%.
2.Declaration Stage at Shanghai Port
As China’s largest foreign trade hub,Shanghai Port handles more than 12,000 TEUs of Japan import cargo on a daily basis in 2026.Relying on the "Single Window" system,Zhongshitong realizes direct data connection between Japan and Shanghai Port.Key operations include:
| Declaration Link | Operation Key Points | Common Problems |
|---|---|---|
| Electronic Declaration | Complete manifest data verification 24 hours in advance to ensure that the name,weight,mark and other information of imported goods are consistent with the bill of lading | The "used equipment" provided by Japanese exporters was not marked with service life,requiring supplementary |
| Pre-Valuation Review | Submit import price data of similar products in the past 3 months to avoid disputes when customs applies the transaction value method | A Japanese cosmetics enterprise had a declared price deviating by more than 20% from the average import price in the same period,triggering customs price query |
| Inspection Preparation | Mark UN number for dangerous goods at the time of declaration,and MSDS must be provided for chemical products (new requirement in 2026) | Failure to submit MSDS in advance led to 48-hour delay in dangerous goods inspection and generated demurrage |
Special Requirements for Different Product Categories in Japan Import Customs Clearance Agency
Supervision priorities for different product categories in Japan import customs clearance differ significantly.Taking the latest 2026 policy as an example:
- General Cargo Category (Apparel / Stationery / Toys): Focus on verification of "brand / material / specification" in declaration elements.Zhongshitong once assisted an enterprise which faced inspection due to inaccurate material description (miswriting "polyester fiber" as "cotton") to complete release within 3 working days by supplementing material certification documents.
- Machinery / Equipment Category: Additional
6 Major Risks and Avoidance Schemes for Japan Import Customs Clearance Agency
According to 2026 data from Zhongshitong,37% of delays in Japan import customs clearance agency are caused by declaration errors.The following are typical risks and countermeasures:
- Declaration elements inconsistent with actual goods: For example,an enterprise declared "general cargo" while the actual goods were dangerous goods,resulting in customs detention of the cargo.Countermeasure: Make
in advance,and compare key parameters (such as weight,volume,material) with actual goods item by item. - Incorrect information on Certificate of Origin: The country of origin in FORM J is inconsistent with the actual situation,leading to loss of tariff preference for importers.Countermeasure: Require Japanese exporters to provide the Certificate of Origin,and simultaneously provide the
issued by Japan Chamber of Commerce and Industry. - Delayed application for import license: In 2026,new regulations require that some imported medical devices shall apply for
in advance.An enterprise failed to apply 2 months in advance,leading to failure of cargo release after arrival.Countermeasure: Verify in advance whether the imported product is listed in ,and establish a "license application calendar". - Exchange loss caused by exchange rate fluctuation: Fluctuation of JPY to CNY exchange rate may increase cost by 10%-15%.Countermeasure: Adopt the strategy of "batch settlement + exchange rate locking",and cooperative banks of Zhongshitong can provide the service of "real-time hedging between customs declaration amount and foreign exchange settlement amount".
- Hidden cost exceeding budget: Document exchange fee (average 2000 RMB per shipment),demurrage (starting from 2000 RMB per day),inspection fee (500 RMB per time),etc.Countermeasure: Specify "upper limit of cost" and "responsible party for extra cost" in the agency contract,and Zhongshitong can provide "preliminary cost estimation sheet".
- Customs inspection delay: The customs inspection rate has risen to 28% in 2026,and a precision instrument was detained at port for 15 days due to inspection.Countermeasure: Apply for "unaccompanied inspection" in advance (applicable to general cargo excluding dangerous goods),and Zhongshitong provides the "inspection green channel" service.
