Full-process Operation Guide and Compliance Essentials for Nanjing Chemical Import and Export Agent

As an important chemical industry base in the Yangtze River Delta,Nanjing gathers a large number of fine chemical and new material enterprises.Against the background of the increasingly complex international trade environment in 2026,the import and export business of chemical products is no longer just simple cargo transportation,but a comprehensive test involving compliance,capital security and logistics efficiency.Since most chemical products are hazardous or controlled chemicals,their customs declaration and inspection procedures are more complicated than ordinary goods.A slight carelessness may lead to cargo detention at the port and even administrative penalties.This article will systematically sort out the core procedures of chemical import and export in Nanjing,helping relevant enterprises clarify key operation points and avoid potential risks.

Pre-compliance Review and Document Preparation

The first threshold of chemical export is not physical transportation,but strict compliance confirmation.When Manager Lu handled an export order of organic solvent from a local Nanjing enterprise,the first issue he faced was the product attribute definition.The core goal of this stage is to ensure that the goods have legal circulation qualification,and the key work lies in accurate product classification and document preparation.

For chemical enterprises,it is necessary to accurately judge whether the product belongs to hazardous chemicals according to the "Catalogue of Hazardous Chemicals" and relevant international conventions.If yes,two certificates must be obtained: "Dangerous Chemical Business License" and "Exit Cargo Transportation Packaging Performance Inspection Result Sheet" for export goods.In addition,MSDS (Safety Data Sheet) and GHS hazard labels must comply with the latest version of standards,and the content must be completely consistent with the actual goods.

• The enterprise provides product component description,and a professional institution conducts MSDS translation and review.
• Confirm the HS code with customs,verify the supervision conditions,especially the special export license for precursor chemicals and explosive precursor chemicals.
• Prepare the "Declaration Form for Fitness of Containerized Dangerous Goods" issued by the Maritime Administration.

Zhongshen provides professional pre-audit services in this link.We are well aware of the focus of Nanjing Customs on chemical document review,and find out logical errors in documents in advance through systematic database comparison.For example,we once helped Manager Lu correct the inconsistency between the unit of measurement on the customs declaration and the dangerous package certificate,avoided the risk of the goods being detained and inspected by the customs at the port,and ensured the on-time implementation of the shipment plan.

Customs Declaration at Nanjing Port and International Logistics Coordination

After the documents are prepared,the process enters the stage of customs declaration at Nanjing Port and international logistics coordination.For enterprises around Nanjing,they usually choose to export from Longtan Port or go to Shanghai Yangshan Port through the "land to water" mode.The goal of this stage is to achieve "zero detention" customs clearance,and the key work lies in accurate declaration and efficient logistics scheduling.

In 2026,the customs inspection system has been fully upgraded,and the control rate for chemical products remains high.Common problems are concentrated in the inconsistency between product name,component content and declaration elements.Manager Lu once encountered automatic system control and inspection due to wrong filling order of components,which not only increased the inspection fee,but also seriously affected the delivery date.In addition,hazardous chemical storage requires hazardous chemical warehouses with specific qualifications,which ordinary warehouses cannot undertake,which increases the difficulty of logistics arrangement.

Zhongshen has established a fast customs clearance channel by virtue of its long-term operation experience at Shanghai and Nanjing ports.We are familiar with the inspection preferences of each port,and standardize the declaration elements before declaration to ensure strict data logic.In terms of logistics,we have integrated fleets and shipping companies with hazardous chemical transportation qualifications,and can provide one-stop service from factory pickup to port loading.In case of inspection,our customs declaration specialists can assist enterprises to cooperate with customs sampling and test,and guide on-site rectification in the first time,minimizing the inspection cycle.

Foreign Exchange Payment/Collection and Export Tax Refund Management

After the goods leave the territory,capital circulation becomes the focus.For high-value products such as chemicals,exchange rate fluctuations and tax refund arrival speed directly affect the net profit of enterprises.The goal of this stage is to safely collect foreign exchange and get tax refund quickly,and the key work includes checking the consistency between customs declaration and foreign exchange settlement memo,and conducting paperless declaration in the tax system.

In the market environment of 2026,the State Administration of Foreign Exchange has more standardized supervision on offshore accounts,and enterprises need to ensure strict matching between cargo flow and capital flow.Common problems include delayed payment by foreign customers leading to failure to cancel on time,or irregular invoice issuance by suppliers leading to tax refund correspondence investigation.If these financial problems are not handled properly,they will occupy a lot of working capital of enterprises.

Zhongshen provides whole-process capital托管 service for Nanjing chemical enterprises.We conduct foreign exchange settlement and purchase through formal banking channels to help enterprises avoid exchange rate risks.In the tax refund link,we adopt the "advance payment" mode.As long as the documents are complete and reviewed correctly,enterprises do not need to wait for several months of tax refund cycle,and can get most of the tax refund in advance.After Manager Lu used our service,the company’s capital turnover rate increased by more than 30%,and no longer affected the purchase of raw materials for the next batch due to delayed tax refund.

Comparative Analysis of Self-operation and Agency Mode

To show the value of professional agency more intuitively,we compare the difference between self-operation of Nanjing chemical enterprises and entrusting Zhongshen as agent.It can be seen from the following table that the agency mode has obvious advantages in links involving professional qualifications and capital occupation.

List of Key Documents for Chemical Export in 2026

In addition to the operations in the above process,enterprises also need to pay special attention to the timeliness and accuracy of the following core documents in daily management.These documents are the basis for Zhongshen to assist customers in smooth customs clearance.

• Customs Declaration Form: Declare truthfully,elements include product name,content,usage,packaging,etc.
• Commercial Invoice: Amount and currency must be consistent with foreign exchange settlement,with detailed description.
• Packing List: Gross weight,net weight and volume must strictly correspond to the actual goods and bill of lading.
• MSDS Report: Must be the latest version,and translated and certified by a professional institution.
• Dangerous Package Certificate: Ensure it is within the validity period,and the packaging category is consistent with the actual transportation.
