WooCommerce - get category for product page

For my WC product pages, I need to add a class to the body tag so that I can perform some custom styling. Here's the function I'm creating for this...

function my_add_woo_cat_class($classes) {

$wooCatIdForThisProduct = "?????"; //help!

// add 'class-name' to the $classes array
$classes[] = 'my-woo-cat-id-' . $wooCatIdForThisProduct;
// return the $classes array
return $classes;

//If we're showing a WC product page
if (is_product()) {
// Add specific CSS class by filter

...but how do I get the WooCommerce cat ID?

Box Box

A WC product may belong to none, one or more WC categories. Supposing you just want to get one WC category id.

global $post;
$terms = get_the_terms( $post->ID, 'product_cat' );
foreach ($terms as $term) {
    $product_cat_id = $term->term_id;

Please look into the meta.php file in the "templates/single-product/" folder of the WooCommerce plugin.

<?php echo $product->get_categories( ', ', '<span class="posted_in">' . _n( 'Category:', 'Categories:', sizeof( get_the_terms( $post->ID, 'product_cat' ) ), 'woocommerce' ) . ' ', '.</span>' ); ?>
