First, you must go to the agricultural administrative agency (Agricultural Bureau) at or above the county level to apply for an agricultural input operating license (this is for agricultural input access); the pesticides you sell are Class B dangerous goods and you must go to the safety inspection If you want to operate ammonium nitrate, you have to go to the Public Security Bureau to apply for a certificate (it is an explosive); if individual pesticides cannot get a certificate now, you have to go to the Agricultural Materials Bureau Or find an affiliated unit at the agricultural station.
If funds and other aspects are relatively sufficient, you can set up a specialized agricultural supplies company, and if you are smaller, you can open a branch.
