Annual analysis of heavy metal and pesticide for Thailand market

Hi,

Does anybody here facing same issue for Thailand export market food regulation that require annual analysis report (heavy metal, pesticide, aflatoxin, etc) I think that is too costly to send every year. Can we issue letter/declaration instead of provide annual analysis? I already explain to sales team that it might be costly for annual testing. But they said it is requirement. I try to search but could not found the specific regulation. Can anybody help me for this kind of issue.

What commodity are you exporting?
