Last July 2020 China government sent to the World Trade Organization a document which gathers the proposed MRLs, G/SPS/N/CHN/1164.
Most of the proposed MRLs are new, it means, right now there are no MRLs for the active in combination with the commodity. However, in some cases there are MRLs already in force for some other combinations (active&commodity).
Usually the new proposed MRL are higher (less restrictive) than the current ones. However not always is like this. In fact, the Chinese authorities have proposed to reduce the MRL (a.k.a. tolerances) for some combinations crop-active. Let´s see some.
Chinese goverment proposes to reduce the allowance of acetamiprid residues on grapes, lemons, papaya, kumquat, melons, papaya and pitaya/dragon fruit. If this proposal goes ahead the tolerances will be reduced from 2 ppm to 0.5 ppm and in some cases to 0.2 ppm. Note «ppm» stands for parts per million, it means, miligrams/kilogram.

Another tolerance to be sharply reduced is the one for chlorantraniliprole(Rynaxypyr) on celtuce (Scientific name: Lactuca sativa angustana) and letture-romaine (Scientific name: Lactuca sativa romana). The current MRL is 20 ppm and the proposal sets the tolerance in 1 ppm for celtuce and 5 ppm for romaine lettuce. (Source: Homologa)
There are another bunch of cases where the MRLs are proposed to be reduced. For more information you can write to firstname.lastname@example.org
