@hube2 Thank you for your answer. I will try to supply with more context.

The idea is as follows: When a order is completed I use the woocommerce_thankyou action in WooCommerce to create an email as follows:

add_filter('woocommerce_thankyou', [$this, 'create_email'], 10, 1);

In my custom fields setup, I’ve created a field group that applies to all products. In the field group I can set a supplier for the product from predefined options in a single select.

What I want is to access that supplier on a product level in the create_email function that runs after an order is completed. My approach is as follows:

public function create_email($order_id)
    {
        global $product;

        $order = wc_get_order($order_id);
        $items = $order->get_items();

        $subject = 'NEW ORDER #' . $order->get_order_number();
        $header = 'New order: #' . $order->get_order_number();

        foreach ($items as $item_key => $item) {
            $product = $item->get_product();

            if (strpos($product->get_slug(), 'vareproeve')) {
                continue;
            }

            $product_id = $item->get_product_id();

             $main .= '<p>ID: ' . $product_id . '</p>';

                if ($supplier = get_field("supplier", $item->get_product_id())) {
                    $main .= '<p><strong>' . __('Supplier: ') . ': </strong>' . $supplier . '</p>';
                }

        }

       // Setup rest of email
        if ($main != '') {
            $body = $head . $main . $foot;

            $this::send_email($recipient, $subject, $header, $body, $headers, $attachments, $order, $order_id);
            update_post_meta($order_id, '_order_mail_sent', 'yes');
            unset($head);
            unset($main);
            unset($foot);
        }
    }
