# Zhongshen Shanghai Zijiang Import Agency: Customs Clearance Efficiency Increased by 30%

## Core Pain Points and Industry Status of Zijiang Import Customs Declaration

In the first half of 2026,the total volume of chemical intermediates and refrigerated agricultural products imported via the Zijiang route of Shanghai Port increased by 18% compared with the same period last year.However,an east China trading enterprise neglected the validity period of the Dangerous Goods Packaging Certificate for imported chemicals,resulting in the cargo being detained at Yangshan Port for 3 days with a direct loss of more than 20,000 yuan.This is one of the typical cases handled by Supervisor Zheng recently.Since Zijiang imported products involve special categories such as hazardous chemicals and refrigerated products,the compliance threshold for customs declaration and inspection has been increasing year by year,which has become a pain point for many enterprises.

Zijiang is an important production base of chemicals and agricultural products in Southeast Asia.In 2026,China Customs added two new regulations for products imported from this region: first,chemical products need to provide low-VOCs test reports issued by the Zijiang Environmental Protection Agency; second,refrigerated fruits need to simultaneously upload real-time temperature curves during transportation.Many enterprises failed to adapt to the new regulations in time,resulting in problems such as document rejection,inspection detention and overtime inspection,and the average customs clearance efficiency dropped by 25%.

## Core Role of Zhongshen in Zijiang Import Customs Declaration

As a foreign trade agency company that has been deeply engaged in Shanghai Port for more than 20 years,Zhongshen has built a full-chain control system from document pre-audit to port release according to the characteristics of Zijiang imported products.The team is not only familiar with the trade policies of Zijiang origin,but also has established a regular communication mechanism with multiple inspection departments of Shanghai Customs,which can respond to the adjustment of new regulations immediately.Since last year,among the Zijiang import business handled by Zhongshen,92% of the cargo has realized "declare and release upon arrival",and the document rejection rate is 15% lower than the industry average.

## Process Breakdown and Targeted Services for Zijiang Import Customs Declaration

### I.Document Pre-audit: Proactively Avoid Compliance Risks

Document requirements for Zijiang imported products vary significantly by category.Chemicals need to provide Dangerous Goods Packaging Certificate,MSDS (2026 edition including toxicity description of the 9th revised edition of GHS),and low-VOCs test report from Zijiang Environmental Protection Agency; refrigerated fruits need to provide origin quarantine certificate,cold treatment certificate,and transportation temperature curve.Supervisor Zheng’s team will conduct "double verification" on the documents provided by the enterprise 7 working days before the cargo is shipped:

- Check the format,validity period and key parameters of documents against Announcement No.12 of 2026 issued by Shanghai Customs;
- Cooperate with Zijiang local agents to confirm the authenticity of documents and their compliance with local policies.

When an enterprise imported epoxy resin produced in Zijiang last year,Supervisor Zheng found that its MSDS did not update the toxicity classification of the 2026 GHS revised edition,and coordinated with the local supplier to make corrections in advance,avoiding the situation that the cargo could not be declared after arrival at the port.

### II.Port Customs Declaration: Adapt to the Fast Channel of Zijiang Routes

Zijiang routes mainly call at Yangshan Port and Waigaoqiao Port.In 2026,Shanghai Customs implemented the "priority inspection" policy for this route,but it needs to meet the conditions such as accurate pre-declaration data and complete documents.Zhongshen’s operation process is as follows:

- Submit pre-declaration data through the "Single Window" 3 days in advance,and simultaneously upload the Zijiang origin traceability QR code (required to be connected to the China Customs traceability system from 2026);
- For refrigerated fruits,coordinate with the cold chain inspection area of Yangshan Port to reserve temperature review equipment in advance,and complete the temperature curve verification within 4 hours after the cargo arrives at the port;
- For chemical products,mark "Zijiang-origin hazardous chemicals" in the remarks column of the customs declaration form to activate the special customs inspection channel.

When a food trading company imported Zijiang mangoes,Zhongshen helped it upload the cold treatment certificate and transportation temperature curve in advance,shortening the original 2-day inspection process to 8 hours and avoiding the deterioration of fruits due to detention.

### III.Commodity Inspection (Inspection and Quarantine): Category-specific Quarantine Coordination

Quarantine requirements for different categories of Zijiang products vary greatly.Zhongshen has developed exclusive service plans for three core categories of products,as follows:

| Product Category | Special Quarantine Requirements for Zijiang Origin (2026) | Zhongshen Assistance Method |
| --- | --- | --- |
| Chemical intermediates (epoxy resin) | Low-VOCs test report issued by Zijiang Environmental Protection Agency (valid for 3 months) | Connect with Zijiang agents in advance to obtain report templates,assist enterprises in coordinating with testing institutions,and ensure that the report complies with the *Import Chemicals Inspection Regulations* of China Customs |
| Refrigerated tropical fruits (mango) | Methyl bromide cold treatment certificate + full transportation temperature curve (recorded every 2 hours) | Coordinate with the cold chain inspection area of Yangshan Port to reserve review equipment,and complete quarantine review within 4 hours |
| Electronic components (chips) | Non-infringement statement issued by Zijiang Semiconductor Association (with specific models marked) | Cooperate with intellectual property agency to review the content of the statement,and ensure compliance with the 2026 revised edition of the *Regulations on Customs Protection of Intellectual Property Rights* |

## Practical Case: Key Practice of Risk Avoidance

In March 2026,a technology company importing Zijiang-produced chips was required by customs to supplement materials because the "non-infringement statement" did not mark the specific chip models.After entrusting Zhongshen,Supervisor Zheng’s team immediately contacted the Zijiang Semiconductor Association,clarified the models and production batches in the statement,and simultaneously uploaded the patent search report of the chips.The declaration was approved at one time,saving 2 days of inspection time and avoiding delivery delay.

The person in charge of the company said: "The compliance requirements for Zijiang imports change every year.It is easy to make mistakes when operating by ourselves.Zhongshen’s pre-audit mechanism has helped us avoid many risks."

## Summary: Value of Professional Agency

From the pre-control of document pre-audit,to policy adaptation for port customs declaration,and to category-specific services in the commodity inspection link,Zhongshen’s full-process agency for Zijiang import products not only helps enterprises shorten the average customs clearance cycle by 30%,but also avoids more than 90% of cargo return risks caused by improper adaptation to new regulations through mechanisms such as "pre-compliance audit" and "dynamic policy update".In response to the continuous growth of import volume on Shanghai Zijiang routes in 2026,Zhongshen will continue to optimize service details for special categories and provide more accurate import agency support for enterprises.
