Answer

this should work for you.

if ( class_exists( 'WooCommerce' ) ) {
        $kode = $product->get_sku();

        $tax = array(
        'STOCK'=>'brand',
         );

        foreach ($tax as $mk_label => $mk_value) {
            $make_array = wp_get_post_terms(get_the_ID(), $mk_value, array("fields" => "names"));
            foreach ($make_array as $value) {
                $mk .= $value.", ";
            }
            echo '<strong>'.$mk_label.' <a href="javascript:void(0)">'.rtrim($mk,", ").' '.$kode.'</a></strong>';
            $mk ="";
        }


    } else {
      echo "please active your WooCommerce plugin.";
    }

We are taking terms dynamically based on current product id and fetching the brand accordingly. Let me know if you need any more help.
