CHINA PESTICIDE REGULATORY UPDATE
On August 12, 2026, China's Ministry of Agriculture and Rural Affairs (MARA) issued Announcement No. 1049, introducing updated formatting and generation requirements for pesticide label QR codes. The new regulation strengthens technical material traceability requirements and will officially enter into force on November 1, 2026.

Background and Context
This updated regulation replaces the previous framework, MARA Announcement No. 2579, issued in 2017. While the foundational QR code system remains intact, regulatory priorities have shifted over the past decade. The initial policy focused on ensuring every product had a unique digital identity. The new mandate focuses on data authenticity and full-chain traceability, transforming the QR code into a verifiable piece of evidence linking raw materials to finished formulations and market distribution.
Key Regulatory Changes
The revised regulation introduces four primary adjustments that agrochemical companies must adopt:
Mandatory Technical Material Traceability: If a formulated pesticide label does not explicitly state the technical material (TC) or technical concentrate (TK) used, scanning the QR code must now display the corresponding TC/TK registration certificate number and the manufacturer's name.
Flexible Unit Identification Codes: The mandatory unit identification code has been modified from a fixed 32-digit string to "at least 32 digits." The strict requirement for randomized numbers from the 12th digit onward has been lifted, allowing enterprises to self-define the code sequence after the 11th digit.
Removal of Temporary Registration Codes: The code indicating "temporary registration" has been abolished, leaving only standard registrations ("PD" and "WP"). The reference website for checking pesticide registration numbers has also been updated to the China Pesticide Information Network.
Strict Production Date Verification: The production date is now a mandatory field on the required traceability web portal. The production date displayed via the QR scan must be consistent with the date printed on the physical product label and instructional leaflet.
Impact Analysis and Compliance Advice
With the regulation taking effect on November 1, 2026, companies have a relatively short transition period. Industry experts emphasize that compliance requires more than just printing new labels. Agrochemical manufacturers should assess whether their internal traceability software and production line inkjet systems require updates to accommodate new data fields and adapt to the revised coding logic.
Notably, the new rules continue to cover enterprises that export pesticides to China. Overseas suppliers must also assign traceability codes to products exported to China in accordance with the new format and ensure that the relevant traceability webpages are accessible on both desktop and mobile devices. Multinational companies will therefore need to adapt their global traceability systems to meet China-specific requirements.
Practical Compliance Checklist
Check whether TC/TK registration information can be displayed through the QR code where it is not stated on the product label.
Review whether existing unit identification code logic meets the new "at least 32 digits" format.
Verify that production dates shown through the traceability webpage are consistent with the physical label and instructional leaflet.
Assess whether traceability software and production line coding systems require updates.
For products exported to China, confirm that traceability webpages remain accessible on both desktop and mobile devices.
Conclusion and Next Steps
MARA Announcement No. 1049 reflects a stricter, data-driven approach to pesticide market supervision in China. The new rules are expected to increase regulatory attention to consistency between physical labels and scanned digital data during upcoming regulatory inspections. Agrochemical manufacturers and global exporters are strongly advised to leverage the remaining compliance window to upgrade IT systems where necessary, adapt packaging designs, and refine quality management protocols before the November deadline.
