Chengdu Dairy Import Customs Clearance Agency: Full Analysis of Compliance Operations in 2026
The import volume of dairy products in western China increased by 12% year on year in 2026.As the core land and air trade hub in western China,Chengdu has seen a surge in demand for customs clearance.However,dairy products are special commodities subject to statutory inspection,under dual supervision of customs and entry-exit inspection and quarantine.Many enterprises fall into difficulties such as inconsistent documents and port detention fines as they are not familiar with the latest 2026 regulatory rules.As a professional foreign trade agency headquartered in Shanghai,Zhongshitong has 20 years of frontline practical experience,providing full-process compliant customs clearance services,breaking geographical restrictions and realizing coordinated operation across ports nationwide.

I.Core Regulatory Requirements for Chengdu Dairy Import Customs Clearance
In 2026,customs and commodity inspection authorities have further tightened supervision standards for dairy imports.The core requirements include:
- Official Certificate of Origin: RCEP member states need to provide certificates of origin that meet the requirements of the agreement,to enjoy preferential agreement tariff up to 0.3%
- Entry Animal and Plant Quarantine Permit: Application needs to be submitted 20 days in advance through the online platform of National Immigration Administration.Chengdu port has opened a green channel,which shortens the approval time by 30%
- Accurate HS Code Classification: There are up to 12 subcategories of dairy products.Wrong classification will directly lead to tariff deviation and change of supervision conditions
- Third-party Test Report: Test reports on total bacterial count,heavy metals and other indicators issued by official institutions of the exporting country are required,which shall comply with China’s national food safety standards
II.Key Process Nodes and Compliance Points for Chengdu Dairy Import Customs Clearance
The following is the standard process of Chengdu dairy import customs clearance in 2026 and compliance requirements for each node.A structured table is organized for reference:
| Process Node | Required Documents | 2026 Compliance Priorities |
|---|---|---|
| Pre-stage Document Pre-review | Trade contract,commercial invoice,packing list,bill of lading | Verify the consistency between HS code and actual goods in advance.In 2026,the customs system will automatically compare the declaration information and imported goods data,and the control trigger rate for errors has increased by 18% |
| Quarantine Permit Application | Enterprise business license,trade contract,product ingredient list | Applications can be submitted online at Qingbaijiang Free Trade Zone,Chengdu,no need for offline submission,and the approval cycle is shortened to 7 working days |
| Port Declaration | Quarantine permit,certificate of origin,test report | Adopt the "advance declaration" mode.Completing the declaration before goods arrive at the port can shorten the customs clearance time by 40%,and electronic documents need to be uploaded in advance |
| Customs Valuation | Transaction value certificate,freight and insurance policy | The 2026 customs valuation system is connected to the global trade database.Authentic transaction records are required to avoid risks of under-declaration or over-declaration of value |
| Inspection and Release | Customs inspection notice,physical sample | Temperature control records for cold chain dairy products shall be prepared in advance.The inspection area at Chengdu port is equipped with special cold chain storage facilities to prevent goods deterioration |
| Tax Payment and Goods Pick-up | Tariff payment receipt,value-added tax payment receipt | The original certificate of origin for goods from RCEP member states shall be submitted to enjoy the agreement tariff,otherwise the goods will be taxed at the most-favored-nation tariff rate |
III.Practical Risk Avoidance: High-frequency Risks and Solutions for Chengdu Dairy Import Customs Clearance
I handled two dispute cases of local Chengdu dairy import enterprises in 2025.In one case,a trading company entrusted an ordinary freight forwarder to handle the import of New Zealand whole milk powder.Due to wrong HS classification,the goods were declared as "other dairy products" but should actually be classified as "whole milk powder",resulting in an extra 2.1% tariff payment totaling RMB 82,000.In the other case,a client failed to apply for the quarantine permit in advance,and the problem was not found until the goods arrived at the port,leading to 7 days of port detention and demurrage of RMB 23,000.Based on these experiences,I summarized three high-frequency risks and corresponding solutions:
- Risk of Wrong HS Code Classification: The HS code for dairy products shall be subdivided according to fat content,packaging specification and processing method.It is recommended to entrust a professional agency for pre-classification in advance.In 2026,customs provides pre-classification service to confirm the accuracy of the code in advance
- Risk of Incomplete Documents: The certificate of origin and health certificate must be issued by official institutions of the exporting country.Forgery or inconsistency will lead to goods return.It is recommended to confirm the document format with overseas suppliers in advance,and Chengdu port provides document pre-review service
- Risk of Hidden Costs: Some freight forwarders conceal expenses such as document exchange fee,demurrage fee and inspection fee.It is recommended to sign a clear cost list before entrustment.Zhongshitong will list all charging items in advance with no extra hidden costs

V.New Policy Changes for Chengdu Dairy Import Customs Clearance in 2026
In 2026,Chengdu port has launched multiple user-friendly policies for dairy imports:
First,the "fast inspection channel for imported dairy products" is opened.For goods from RCEP member states,the inspection time is shortened to less than 4 hours.Second,the traceability management requirements for imported dairy products are adjusted.Enterprises need to provide full-chain traceability information covering production to transportation,and Zhongshitong can assist clients to establish a traceability system to ensure compliance with regulatory requirements.Third,import tariffs on some dairy products are reduced.For example,the most-favored-nation tariff rate for low-fat milk powder is reduced from 10% to 8%,and goods from RCEP member states can enjoy further preferential rates.
It should be noted that customs has strengthened anti-counterfeiting efforts for dairy products in 2026.Enterprises that forge certificates of origin or test reports will be fined 1 to 3 times the value of the goods,and will be included in the customs dishonest enterprise list,which will affect all subsequent import and export businesses.Therefore,choosing a professional customs clearance agency is particularly important.
