The Chinese standard GB2763-2019 sets the MRLs that currently applies for plant protection products’ residues in China.
This standard was published on 15 August, 2019 and entered into force on 15 February, 2020.
Since then, China has notified to the World Trade Organization (WTO) three drafts about Maximum Residue Limits:
G/SPS/N/CHN/1149 (January, 2020)
G/SPS/N/CHN/1164 (July, 2020)
G/SPS/N/CHN/1172 (September, 2020)
Moreover, on 23 November 2020 the Chinese Ministry of Rural Affairs published a new MRL proposal. For the time being, this proposal has not been sent to WTO yet.
The MRL currently in force are available at Homologa database along with the three drafts sent to the WTO. The last proposal which is under public consultation will be available as soon as the final draft is published.
Dealing with such amount of documents from different sources and not easily accessible, is not straightforward. Homologa uses different strategies.
On the one hand, when analysing and harmonizing the documents, Homologa´s team has found that some proposals overlap. It means that two or more different MRLs values were proposed for the same active-crop combinations. In these cases, Homologa shows the most recent proposal´s value as the “Future MRL”.
On the other hand, as the original documents are in Chinese, Homologa team´s gets help from our collaborator based on Taiwan for helping with tricky cases. Most importantly, the software created by Homologa´s developers carries out checks to avoid doubles and misleading information. By this way, Homologa database offers a reliable and clean version of all current and future Chinese MRLs in a consolidated and harmonized way which allows cross-comparison among countries.
