Dujiangyan Import Customs Clearance Agency: Full Process Operation and Compliance Key Points Analysis

Dujiangyan Import Customs Clearance Agency: Focus on Compliance Customs Clearance for Food and Mechanical and Electrical Products

In 2026,the continuous upgrading of cultural and tourism industry in Dujiangyan has driven an 18% year-on-year increase in imports of products such as Southeast Asian tropical fruits,European dairy products and small processing agricultural machinery.However,many local enterprises reported that during import customs declaration,inconsistent documents and poor connection of quarantine procedures often lead to goods being detained at the port for more than 3 days,and some fresh products even deteriorate due to delays.

As a Shanghai-based enterprise with more than 20 years of experience in foreign trade agency,Zhongshen provides full-process connection services from document pre-audit to port customs clearance according to the regional and category characteristics of imported products in Dujiangyan.It is especially good at coordinating the connection between local ports and quarantine departments to help enterprises avoid compliance risks.

1.Document Pre-audit: Avoid Core Compliance Risks in Advance

For food and mechanical and electrical products imported to Dujiangyan,as they involve quarantine standards of different countries and domestic regulatory requirements,document pre-audit is a key pre-process for customs clearance.Take Southeast Asian fruits as an example: in 2026,China requires supplementary Cold Treatment Certificate and origin epidemic notification verification records for imports of durian and mangosteen from Thailand,Malaysia and other origins; European dairy products need to provide the Pathogen Detection Report issued by the EU Health Directorate.

During the document pre-audit stage,Zhongshen develops exclusive checklists for different products:

In 2025,a trading company in Dujiangyan imported frozen durian from Malaysia.Without preparing the Chinese translation of the Cold Treatment Certificate in advance,the company was required by the quarantine department to supplement the document after the goods arrived at the port,resulting in 3 days of detention.After receiving the request for help,Zhongshen immediately assisted in supplementing the translation and coordinated with the quarantine department for priority review,and finally completed the document correction within 24 hours,avoiding the loss of goods deterioration.

2.Port Customs Declaration: An Efficient Channel Connecting Transit and Declaration

Local ports in Dujiangyan are mainly for road transit.Most imported goods enter through Shanghai Port and Ningbo Port and then transit to Dujiangyan.The core difficulties of this link are the information consistency between the transit declaration form and the customs declaration form,and the connection efficiency with the port customs broker.

The core actions of Zhongshen in the port customs declaration stage include:

• Connect with Shanghai Port customs brokers in advance to confirm the manifest information of transit goods,avoid inconsistency between manifest and bill of lading
• Optimize the filling format of the transit declaration form according to the transit requirements of Dujiangyan local ports,ensure that the information is consistent with the customs declaration form
• Arrange special personnel to follow up the transit transportation process,coordinate customs supervision and inspection of transit goods,reduce inspection time

In 2026,an agricultural machinery trading company in Dujiangyan imported a small German seeder.The Shanghai Port Customs required modification because the 3C certification number of the equipment was not marked on the transit declaration form.Zhongshen immediately assisted in supplementing the certification number,and coordinated with Dujiangyan Port Customs to confirm the transit connection process in advance.Finally,it only took 2 days to complete the transit and customs declaration,saving 3 days compared with the conventional process.

3.Commodity Inspection Link: Targetedly Solve Special Quarantine Requirements

In the commodity inspection link of imported food in Dujiangyan,it is necessary to focus on origin epidemic,product composition testing and the compliance of Chinese labels; for mechanical and electrical products,it is necessary to verify equipment safety standards and the validity of 3C certification.Zhongshen has established a green channel with local commodity inspection institutions,can book inspection time in advance,and provide customized quarantine assistance for different products:

Take European dairy products as an example: in 2026,China requires imported milk powder to test 12 indicators including melamine and Cronobacter sakazakii,and the Chinese label must mark 10 items including nutritional composition and shelf life.Zhongshen will assist enterprises to complete the pre-audit of Chinese labels before commodity inspection,avoiding being required for rectification due to unqualified labels.

In 2025,a supermarket in Dujiangyan imported Spanish whole milk powder,and was required for rectification by the commodity inspection department because the Chinese label did not mark "not suitable for 0-6 months old infants".Zhongshen assisted the enterprise to redesign the label and passed the pre-audit,and the inspection was completed in only 1 day during commodity inspection,saving 2 days compared with the conventional process.

Core Values of Zhongshen Agency Service

Through full-process pre-audit,efficient connection and customized assistance,Zhongshen can shorten the conventional cycle of Dujiangyan import customs clearance from 7-10 days to 3-5 days,while avoiding the following core risks:

• Risk of customs declaration rejection and cargo detention caused by inconsistent documents

In 2026,a food trading company in Dujiangyan imported Thai mangosteen through Zhongshen agency service,which only took 4 days from document pre-audit to completion of customs clearance,saving 5 days compared with self-declaration,and no compliance problems occurred,effectively guaranteeing the freshness of fresh products.
