How to check if Context.Item is uCommerce item or Sitecore item

Question

I am developing a Language Switch for Sitecore-uCommerce solution and using the default uCommerce Item Resolver and UrlService to get nice URLs. So I have the URLs like http://sitename/catalogname/productname/c-XX/p-YY.

Then for every sitecore 'page' item I use LinkManager.GetItemUrl(Context.Item, options) with LanguageEmbedding.Always option.

Now, if my Context.Item is a uCommerce item, then my URL is http://sitename/nl/sitecore/ucommerce/products/3/34/productname/, which will not be caught by uCommerce Item Resolver and I will have the document not found error.

So what I need is to check before if Context.Item is uCommerce item and use URLService instead of LinkManager.

Question: Is there in uCommerce a class like TemplateIDs similar to Sitecore.TemplateIDs? This way I could check if my item derives from base ucommerce product template.

If there is no a better solution, here is what I've done:

public static class TemplateIDs
{
    // sitecore/ucommerce item's template id       
    public static ID UCommerce => new ID("{AABC1CFA-9CDB-4AE5-8257-799D84A8EE23}");
}

public static class ItemExtensions
{
    public static bool IsUCommerceItem(this Item item)
    {
        var items = item.Axes.GetAncestors();
        return items.Any(x => x.TemplateID.Equals(TemplateIDs.UCommerce));
    }
}

//How to use
if(Sitecore.Context.Item.IsUCommerceItem()) 
{
    //Do your stuff 
}
