Here is how I have the base64data defined.
base64data VarChar(4096) CCSID(1208);

Have you checked the SQL State and SQL Code?
How is Labelresponse.base64data defined?
Is it defined VARCHAR(4096) CCSID(1208)?
Is it CHAR with trailing whitespace?
Did you try to trim it?
To do base64 decoding, I normally use base64_decode from Scott Klement's BASE64R4 module.
Looks like the input to systools.base64decode must be:
"A character string in CCSID 1208 that is currently Base64 encoded. The length cannot exceed 4096 characters."

Subject: Base64Decode
Hi All
This is the first time I am working the a Base64 returned value from a web service.
It's the shipping label from a carrier.
When I use Labelary, paste in value and decode it show the label as expected.
Where I am having issues is in the exec sql set :DecodedLabel = systools.base64decode(:Labelresponse.base64data)
Either I get nothing in the DecodedLabel or not ZPL type data.
I have tried several different combinations of CCSID (including nothing) on the DecodedLabel but just not working.
Dcl-S DecodedLabel VarChar(4096) CCSID(1208);
What is the obvious thing I am doing wrong?
