The United States applies additional tariffs on all HTSUS codes that represent products that may contain steel and aluminum, depending on the amount of metal in the product. By default, US Customs and Border Control will assume these products contain 100% metal unless it is specified differently on the commercial invoice.
Previously, our duties and import tax calculations in checkout applied the same default - assume those products contain 100% metal. Now, duties and import taxes supports customizing the percentages of your product's value that Section 232 steel and aluminum tariffs apply to.
This new setting applies to all items in your store that fall under Section 232. To customize this amount, visit your admin's duty settings and enter the percentage in "United States Section 232 percentage".
To ensure you also recieve a reduced rate when shipping your orders, ensure you also update your commercial invoices to reflect your product's proportion of metal.
