Hi,

This is what you were trying to write

#!/usr/bin/perl --
package xyz;
require Exporter;
*import = \&Exporter::import;
use strict;
use warnings;
our @EXPORT_OK = qw(@overall @electronics @safety);
our @products  = (
    [ "MG-20", 1,  2,  3 ],
    [ "JU-54", 2,  3,  1 ],
    [ "HY-21", 3,  1,  2 ],
    [ "OK-34", 4,  10, 5 ],
    [ "GT-75", 9,  6, 0 ],
    [ "KJ-23", 6,  8,  7 ],
    [ "PO-65", 7,  5,  10 ],
    [ "HN-34", 8,  6,  9 ],
    [ "ED-23", 9,  7,  4 ],
    [ "FR-98", 10, 4,  8 ],
);
our( @overall, @electronics, @safety );
{
    for my $i ( 0 .. @products ) {
        push @overall,     $products[$i][1] . ":" . $products[$i][0];
        push @electronics, $products[$i][2] . ":" . $products[$i][0];
        push @safety,      $products[$i][3] . ":" . $products[$i][0];
    }
}
1;
__END__

Actually this is what you were trying to write

#!/usr/bin/perl --
package xyz;
require Exporter;
*import = \&Exporter::import;
use strict;
use warnings;
our @EXPORT_OK = qw(@overall @electronics @safety);
our @products  = (
    [ "MG-20", 1,  2,  3 ],
    [ "JU-54", 2,  3,  1 ],
    [ "HY-21", 3,  1,  2 ],
    [ "OK-34", 4,  10, 5 ],
    [ "GT-75", 9,  6, 0 ],
    [ "KJ-23", 6,  8,  7 ],
    [ "PO-65", 7,  5,  10 ],
    [ "HN-34", 8,  6,  9 ],
    [ "ED-23", 9,  7,  4 ],
    [ "FR-98", 10, 4,  8 ],
);
our @overall     = map { $_->[1] . ':' . $_->[0] } @products;
our @electronics = map { $_->[2] . ':' . $_->[0] } @products;
our @safety      = map { $_->[3] . ':' . $_->[0] } @products;
1;
__END__

So that you could write something like this (no exporting required)

use Data::Dump qw/ dd/;
use xyz qw/ @safety /;;
dd( \@safety , \@xyz::safety );
__END__do {
  my $a = [
    "3:MG-20",
    "1:JU-54",
    "2:HY-21",
    "5:OK-34",
    "0:GT-75",
    "7:KJ-23",
    "10:PO-65",
    "9:HN-34",
    "4:ED-23",
    "8:FR-98",
  ];
  ($a, $a);
}
