 <p>As this module only depends on the <em>product</em> module and that module doesn’t provide any menu entry, this module lacks a menu entry for H.S. Codes. A menu entry for H.S. codes is provided by the module <em>product_harmonized_system_stock</em>.</p>
 <p>Once the H.S. codes are created, you will be able to set the H.S. code on a product (under the <em>Information</em> tab) or on a product category. On the product form, you will also be able to set the <em>Country of Origin</em> of a product (for example, if the product is <em>made in China</em>, select <em>China</em> as <em>Country of Origin</em>).</p>
