I know you have got your answer...but since I got he code, I am posting here
Code:
awk '/\"NEW PRODUCT, VERSION 1[.]1\"/ {if(n) {l = l < n ? n : l; print "\"NEW PRODUCT, VERSION 1.1\""; print prod; print head; for(i = 1; i < l-1; i++){print A[i]}; l = 0; n = 0; print ""}; head = ""; val = ""; getline; prod = $0; split(x, A); next}
/\"PRODUCT FIELD\"/ {l = l < n ? n : l; n = 1; next}
n == 1 {head = head == "" ? $0 : (head "\t" $0); n++; next}
n >= 2 {A[(n-1)] = (A[(n-1)] == "") ? $0 : (A[(n-1)] "\t" $0); n++}
END {l = l < n ? n : l; print "\"NEW PRODUCT, VERSION 1.1\""; print prod; print head; for(i = 1; i < l-1; i++){print A[i]}}' Item_List.txt

One last thing. In the input file there is the possibility that there will be blank spaces for some of the data values. For instance;

Code:
 
"NEW PRODUCT, VERSION 1.1"
PRODUCT_01
"PRODUCT FIELD"
FIELD_X
3333333.0000000
  
4444444.0000000

The output looks like;

Code:
 
"NEW PRODUCT, VERSION 1.1"
PRODUCT_01
"PRODUCT FIELD"
FIELD_X
3333333.0000000
4444444.0000000

Is there a way to keep the blank spaces?

column

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME

     column -- columnate lists

SYNOPSIS

     column [-tx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.	Empty lines are ignored.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the -t option.

     -t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default, or with
	     the characters supplied using the -s option.  Useful for pretty-printing displays.

     -x      Fill columns before filling rows.

     column exits 0 on success, >0 if an error occurred.

ENVIRONMENT

     COLUMNS  The environment variable COLUMNS is used to determine the size of the screen if no other information is available.

EXAMPLES

	   (echo "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME"; 
	   ls -l | sed 1d) | column -t

SEE ALSO

     colrm(1), ls(1), paste(1), sort(1)

HISTORY

     The column command appeared in 4.3BSD-Reno.
