Why isn't my 'coming soon' product tag showing up?

[newuser01]

Apparently I need to replace the painting kidumaru badge as "coming soon".

I already added a tag "coming soon" tag for the painting, I tried this code but its not working. Can someone lend a hand? really need help

  {% if product.tags contains 'new-product' %}   
    <div class="badge-overlay">
       <span class="bottom-right badge pink"> Coming Soon </span>
            </div>
      {% endif %}
