For your sales to customers located outside of the United States, we are not the retailer of record, but are acting as your "disclosed agent".  This means that you are selling the products directly to those customers. Value Added Taxes (VAT) may arise when you sell to customers in certain countries, and if so, you will be required to pay the VAT to that country's tax authority.  Your obligation to pay VAT may differ depending on the products and countries involved.  You should therefore seek VAT advice from your tax advisor on all sales to customers in the EU, including the UK.
