We now ship all items to UK mainland free of charge via Royal Mail.


We are shipping to the EU as usual, usually with Royal Mail ‘tracked and signed’, with no or minimal import duties. You will be given a shipping cost at checkout before being asked to pay.

You automatically SAVE THE 20% UK VAT.
When you checkout and select a delivery country in the EU the 20% UK VAT is automatically deducted from your order total. No need for VAT refunds this is done automatically. This does not include harness mount items. 

When your order arrives in the destination country you will have to pay your country specific VAT & any import duty. The courier will contact you via text or e-mail with the instructions of how to do this. The process is very quick and your order will be delivered to you as soon as your country specific VAT is paid.

VAT and Import Duties
Applicable shipping is displayed during checkout. Please note there is no option to pay duties up front. You will have to pay the VAT & any duties directly. The courier delivering your order, or customs from your country, will text or e-mail you with instructions on how to make the payments. 

In most cases the VAT will be roughly equivalent to the UK VAT that we automatically deduct from your order. UK VAT is 20% and most EU countries are between 20% and 23%. 

As our fins are manufactured in the UK you will pay no import duty. 


We ship worldwide! And we’ve now removed the 20% UK VAT.


Harness mounts are shipped directly from the K4 Fins headquarters, usually with TNT who we’ve found to be reliable and reasonably priced. To some countries the cost is too prohibitive to ship the mounts via courier, so the best/only option is to ship the ‘standard’ or ‘extended’ mounts via Royal Mail ‘tracked and signed’.
