enter code here
foreach ($sale_carousel_items_content as $item) {
if ( isset( $item['product_id'] ) ) {
$product = new WC_Product( $item['product_id'] );
if ( $product->is_on_sale() ) {
$countdown_container_id = uniqid('countdown',false);
$target = explode("-", $item['target_date']);
$carousel_items .= '<li class="row"><div class="img-wrapper col-xs-12 col-md-6">';
$carousel_items .= ''.$product->get_image( 'shop_catalog' ).'';
$carousel_items .= '<h6>'.$product->get_shipping_class_id().'</h6></div>';
$carousel_items .= '<div class="counter-wrapper col-xs-12 col-md-6"><h6>'.$product->get_name().'</h6>';
// Short Description
$carousel_items .= '<div class="woocommerce-product-details__short-description"><h6>'.$product->get_short_description().'</h6>';
// Sale value in percents
$percentage = round( ( ( $product->get_regular_price() - $product->get_sale_price() ) / $product->get_regular_price() ) * 100 );
$carousel_items .= '<span class="sale-value" style="background:orange;"><font style="font-size:15px;">특판가 </font>-'.$percentage.'% </span>';

//$carousel_items .= '<div class="countdown-wrapper">';
if ( $item['pre_countdown_text'] && $item['pre_countdown_text'] != '' ) {
$carousel_items .= '<p>'.esc_attr($item['pre_countdown_text']).'</p>';
}
//$carousel_items .= '<div id="'.$countdown_container_id.'"></div></div>';
//$carousel_items .= '<div class="price-wrapper">'.do_shortcode('[add_to_cart id="'.$item['product_id'].'"]').'</div>';
if ( $target && $target!='' ) {
$carousel_items .='
<script type="text/javascript">

$(document).ready(function() {
var container = $("#'.$countdown_container_id.'");
var newDate = new Date('.$target[0].', '.$target[1].'-1, '.$target[2].');
container.countdown({
until: newDate,
});
});
})(jQuery);
</script>';

Final update
Use the following to get the term name (label name) from a product shipping class Id:
$term_id = (int) $product->get_shipping_class_id(); // Get the shipping class Id
$term_name = ''; // Initializing
if( $term_id > 0 ) {
$term = get_term( $term_id, 'product_shipping_class' );
if( is_a( $term, 'WP_Term') ) {
$term_name = $term->name;
}
}
// testing output
echo '<h6>'. $term_name .'</h6>';
So in your code replace the line
$carousel_items .= '<h6>'.$product->get_shipping_class_id().'</h6></div>';
by the following code block:
$shipping_class_id = (int) $product->get_shipping_class_id(); // Get shipping class Id
$shipping_class_name = ''; // Initializing
if ( $shipping_class_id > 0 ) {
$shipping_class_term = get_term( $shipping_class_id, 'product_shipping_class' ); // Get the WP_Term Object
if ( is_a( $shipping_class_term, 'WP_Term') ) {
$shipping_class_name = $shipping_class_term->name; // The label name (term name)
}
}
$carousel_items .= '<h6>'.$shipping_class_name.'</h6></div>'; // Add to output
Tested and works.
