We currently use Emporium Plus Miscellaneous Fee module for "Heavy Shipping Surcharge" on certain products.
We typically offer free US shipping over X, along with other popular shipping options. However, we have some products that are very heavy and we use old man Weiland's Miscellaneous Fee module to add a Heavy Shipping Surcharge in addition to applicable shipping option.
