I have a specialty part here in the USA that I need to ship to the UK to have a plating/coating put on it by a UK-based company. This part will be processed and shipped back to me in the USA. I would like to know if there is a way to NOT have to pay duties and VAT since the part will not remain in the UK and is not being sold. I understand VAT/duties may need to be paid on the coating portion when it is re-imported back to the USA. If anyone knows how I should code and categorize this, I would be grateful for the help as I've not found anything on the internet about this. Thanks in advance for your help.
