The grep utility evaluates basic regular expressions. Unfortunately, (SH?*???????????????US.*) is a filename matching pattern; not a BRE.
To search for lines in a file that match a pattern matching expression, try the following shell script using any shell that recognizes basic Bourne shell syntax (such as ksh and bash):
Furthermore, since you didn't quote the expansion of $INPUT_FILE_T in your grep command, the shell expanded that variable into a list of matching filenames in the current directory before calling grep; so (assuming that the file PCF_STARHUB_20130625_1 contained a list of some of the files in the current directory) the command that you ran was expanded by the shell to:
which treated SH_5.55916.00.00.100029_20130601_0001_US.csv.gz|349|1700116234 as a basic regular expression that happens to match itself when looking in the file PCF_STARHUB_20130625_1 and, fortunately, doesn't seem to have matched any lines in the file named SH_5.55916.00.00.100038_20130601_0001_US.csv.gz|199|2099616349.
To use grep instead of a loop in the shell, you could translate the filename matching pattern SH?*???????????????US.* to a corresponding BRE (SH..*...............US[.].* or more succinctly SH.\{16,\}US[.].*) and use:
Note that the double quotes in the above grep command are crucial to keep the shell from trying to expand the BRE as a filename matching pattern

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
