Dear Sup.Koi,
Per your story brought up about no different of Frozen XX Paste between Pesticide Free version and normal version, which you are concern about mis-delivery into production line.
As discuss, please take photo of packaging of both and share with Purchasing Dept. to let supplier known and request for different tape / label to help avoiding any mistakes that may occur.
Good point bringing up, you are the one who are close to operation site and workers.
Whichever you can help them less mistaken, it’s better for them.
