If a security agreement or other writing that evidences a security interest describes collateral covered by the security interest merely as either consumer property, commercial property or equipment, then that alone is not a sufficient description of collateral for the security interest to be enforceable against third parties (persons other than the grantor).
In addition, the collateral must be described by item or class1, for example:
“commercial property – all wine vats owned by the grantor” (reference to class), or
“commercial property – the ten wine vats owned by the grantor and located at its winery” (reference to item).
