Is there any shortcode to call the product description(text field under the title)?

For now I'm using another custom field to do this job but it will be better if I use the woocomerce field.

You can build your own shortcode this way:

add_shortcode( 'product_description', 'display_product_description' );
function display_product_description( $atts )
 $atts = shortcode_atts( array(
 'id' => get_the_id(),
 ), $atts, 'product_description' );

 global $product;

 if ( ! is_a( $product, 'WC_Product') )
 $product = wc_get_product($atts['id']);

 return $product->get_description();

Code goes in function.php file of your active child theme (active theme). Tested and works.

Examples of USAGE [product_description]

1) In the current product page ph:

echo do_shortcode( "[product_description]" );

2) In any php code providing the related product ID

echo do_shortcode( "[product_description id='37']" );

I wrote a very similar solution to @LoicTheAztec's answer above, but slightly more defensively (as his solution was breaking Elementor edits for me due to there not being a product context when it executes the shortcode on save).

It also solves your paragraph/newline issue as the content is formatted (basically replacing newlines with <p> tags) before returning.

function custom_product_description($atts)
 global $product;

 try 
 if( is_a($product, 'WC_Product') ) 
 return wc_format_content( $product->get_description("shortcode") );
 

 return "Product description shortcode run outside of product context";
 catch (Exception $e) 
 return "Product description shortcode encountered an exception";
 

add_shortcode( 'custom_product_description', 'custom_product_description' );
