Selling Excisable Items to the EU from UK, shipping with duties paid postal service

So, my items attract excise duty in the EU. The only way I can reliably ship them from the UK to the EU, without the recipient being contacted for money is to send using a duties paid postal service.

In order to do this to the EU I must set my selling price to include the product price, import vat, import duty (if any) and excise duty. In this scenario, the EU customer cannot reclaim anything, as all they paid was the product price and no tax (even though it was included as part of product price). I then need Amazon to sell my item to the customer for that price and payout the whole order total (minus their fee of course).

At the moment it would appear that my items when sold B2C in the EU, Amazon takes off VAT from the payout, remits this to the EU and tells me to ship my items IOSS.

Unfortunately shipping excisable Items under IOSS is not allowed by the EU.

So how do I get Amazon to recognise my products are excisable, payout the whole total without removing VAT and leave it up to me to pay VAT and duties to my courier when I send duties paid.

At the moment Amazon is telling me to send IOSS, which will just result in my items getting stopped at the border and my recipient's being billed for the excise duty, and probably double VAT.

I am UK VAT registered, no EU VAT registrations and well under any EU thresholds.

Is this possible? How on earth can I sell my excisable products into the EU. I have the exact same issue with eBay. I can't turn off IOSS.
