We manufacture systems mainly for the printing industry. For our main products the HS Tariff Code is 84439990. I currently have an HMRC export review being undertaken and one of the questions raised by the reviewing officer concerns how the goods were declared by the freight agents to them. Our goods are declared as "NOT SUBJECT TO EXPORT CONTROL". I have been asked to provide evidence to support this, such as a rating from the Export Control organisation of the Department for Business, Innovation and Skills (BIS), to support these declarations. I have used the BIS Goods Checker and cannot find any requirement for our goods to have any licences. This is of course provided I have typed the correct descriptors, but I thought that, provided you have checked, you can "self-certify", ie self-assess. Is there anything else I would need to do or provide?
