Detailed Explanation of 2026 Chemical Products Import Customs Declaration Agency Procedures and Compliance Key Points

Background and Common Difficulties of European Chemical Products Import Customs Declaration in 2026

In 2026,as one of the main sources of China’s chemical product imports,Europe sees a continuous growth in shipments of high-end organic chemical raw materials,fine chemicals and other categories.However,many Shanghai-based enterprises that handle import declaration on their own often encounter a series of problems due to unfamiliarity with the unique compliance and quarantine requirements for chemical products.

• Errors in hazardous chemical classification identification: Some chemical products are hazardous chemicals,but the classification report provided by the enterprise does not meet the requirements of China’s 2026 updated Catalogue of Hazardous Chemicals,resulting in customs declaration rejection;
• Complex documentation: More than a dozen documents including MSDS (Material Safety Data Sheet),UN number,packaging identification report,certificate of origin are required,and enterprises often miss key documents;
• Complex port quarantine procedures: Some chemical products require radioactivity testing and packaging sealing testing.If the testing institution is not booked in advance,it is easy to cause customs clearance delay;
• High compliance risk: If the declaration elements are inaccurate (such as wrong hazardous chemical number),the enterprise may be penalized by the customs,which affects its subsequent import and export qualification.

Core Role of Zhongshen in Chemical Products Import Customs Declaration

Zhongshen has been deeply engaged in the foreign trade agency industry for over 20 years,and has established a complete full-process agency system targeting the particularity of chemical product imports.As the head of Zhongshen’s chemical product agency team,Manager Zhu has handled hundreds of batches of European chemical product import business.He stated: "The core of chemical product import is ’compliance first’.Our team will intervene in all links in advance before the cargo arrives at the port,to help enterprises avoid unnecessary detours."

Decomposition of Chemical Products Import Customs Declaration Process and Compliance Control

1.Document Pre-review Stage: Avoid Compliance Risks in Advance

The document requirements for chemical product imports are far stricter than those for ordinary goods,among which the compliance of MSDS and hazardous chemical classification identification are the core points.China updated the Catalogue of Hazardous Chemicals in 2026,and the classification standards of some European chemical products are different from domestic standards.

Zhongshen’s support includes:

• After receiving the MSDS provided by the enterprise,Manager Zhu’s team will check key information such as safety data and classification number against China’s 2026 hazardous chemical standards.If any inconsistency is found,the team will guide the enterprise to contact the overseas supplier for update;
• For chemical products that require an import license (such as some precursor chemicals),the team assists the enterprise to prepare application materials in advance and coordinate with relevant authorities for processing,avoiding the situation that the cargo cannot be declared after arriving at the port;
• Check auxiliary documents such as certificate of origin and packing list to ensure all information is consistent and free of contradictions.

2.Port Customs Declaration Stage: Accurate Declaration Improves Efficiency

The declaration elements of a chemical product customs declaration form need to include more than 10 special elements such as UN number,hazardous chemical classification number and packaging grade.If the declaration is wrong,the customs will directly reject the form.

Zhongshen’s support includes:

• Dedicated personnel liaise with Shanghai Port Customs,and use the electronic port system to submit declaration documents quickly,avoiding delays caused by paper declaration;
• All elements are rechecked before declaration to ensure the UN number matches the hazardous chemical classification number.If there is any doubt,communicate with the customs in advance;
• If the customs raises any questions,Manager Zhu’s team will supplement relevant supporting materials immediately to reduce communication time.

3.Port Quarantine Stage: Book in Advance for Fast Testing

Quarantine requirements for chemical products vary by category: some fine chemicals require packaging sealing testing,some inorganic chemicals require radioactivity testing,and some environment-related chemicals require environmental impact assessment.

Zhongshen’s support includes:

• According to the characteristics of the chemical product,contact the designated testing institution at Shanghai Port in advance and book the testing time,avoiding queuing after the cargo arrives at the port;
• Prepare packaging identification report,testing samples and other materials to ensure smooth testing;
• If any abnormality is found in the test (such as unqualified packaging sealing),assist the enterprise to contact the overseas supplier to replace the packaging,or guide the domestic warehouse to carry out rectification.

Practical Case: Compliance Risk Avoidance for European Chemical Product Imports

In March 2026,a new material enterprise in Shanghai imported a batch of organosilicon monomers from Germany.When handling declaration by itself,the customs rejected the declaration because the hazardous chemical classification in the MSDS did not meet China’s new 2026 national standard (originally classified as Class 3 flammable liquid,adjusted to Class 4 flammable solid under the new standard).The cargo was detained at the port for 5 days,resulting in extra storage and detention fees.

The enterprise then contacted Zhongshen,and Manager Zhu’s team intervened immediately:

• Check the requirements of the new national standard immediately,guide the enterprise to contact the German supplier to update the MSDS and supplement safety data that meets Chinese standards;
• Reorganize all documents to ensure the classification number is consistent with the declaration elements;
• Book commodity inspection and testing in advance,complete quarantine within 2 days after the cargo arrives at the port,and complete customs clearance within 3 days,avoiding further losses.

The person in charge of the enterprise said: "We did not know the Catalogue of Hazardous Chemicals was updated in 2026.Thanks to the professional team of Zhongshen,we avoided greater losses."
