Function module 'BAPI_OBJCL_CREATE' can be used to upload new material classification data, and the function module 'BAPI_OBJCL_CHANGE' can be used to change existing material classification data. Before doing the upload data, it's better to verify the material classification already existed or not by function module 'BAPI_OBJCL_GETDETAIL'.
Be careful regards classification data as existing or not by checking the return message type from 'BAPI_OBJCL_GETDETAIL'.
Nothing special for new classification assignment& creation for material, little tips when comes to change mode as material classification contains 3 different types of data and has to consider new data merged with already existing data without changes. Just refer to the below code as a reference.
Besides, there's one SAP Note about this change FM: 2217098 - BAPI_OBJCL_CHANGE - some existing characteristic values are cleared.

- <S>: Currently, material already has such an assignment for this specific classification.
- <I>: Assignment doesn't exist now. But could be been created before then deleted later.
- <E>: There'll be no error no matter assignment existed or not for this specific classification, but errors like not existing material.
