The I.V.I. is depending on what is stated on the import permit. 
Please send me the import permit a.s.a.p. so I can check if the I.V.I. is needed. The I.V.I. stands for ‘instruction for inspection’, this is needed when there are additional declarations on the import permit, which are required by the Thai authorities, but which are not required by the Dutch Authorities. To get those additional declarations on the phytosanitary certificate we will have to pay a fee of € 250,00. 
So please make sure you will send me the import permit. With no import permit, we cannot send the peonies to Thailand. 
Met vriendelijke groet – With kind regards,
