There are some errors as get_post_meta() first argument need to be a defined product ID here (and in your code post_ID is not even dynamic variable and will not give anything)…
Try the following:
<?php
function check_gtin(){
if ( $gtin = get_post_meta(get_the_id(), 'gtin', true) ){
echo "gtin13:". $gtin;
} else {

The $havemeta variable isn't defined inside your shopping_location_text() function, so it isn't available for use there.
For a quick fix (or for testing/toying) you can move your code inside the function, like this:
add_action( 'woocommerce_before_main_content', 'shopping_location_text', 10 );
function shopping_location_text() {
global $current_user;

$boat_safety_terms_cleaned_sorted = sort( $boat_safety_terms_cleaned );
error_log( print_r( $boat_safety_terms_cleaned_sorted, TRUE ) );
PHP's sort accepts an array reference and sorts in-place, and returns success or failure - hence the 1 you're getting. You want:
sort( $boat_safety_terms_cleaned );
error_log( print_r( $boat_safety_terms_cleaned, TRUE ) );...
