hi i have integrated Sendcloud with odoo, for eCommerce, but when i make an order from our website, pick the items and make payment, it gives this error, about the HS code as i know the HS code is required if delivery abroad but all our deliveries locally in the UK do i need to add HS code for all products  

(Internal server error Harmonized System Code is mandatory when shipping outside of EU and to some states. You should set the HS Code for product.....)
