Inwards Processing Relief is an HMRC authorisation allowing for relief on customs duty and import VAT on goods imported that are processed, and subsequently re-exported.

Conversely, a sophisticated manufacturing process, such as building a submarine, could be granted 12+ months.

For example, a simple exercise of taking the product out of a box and splitting it might be granted a 3-month Inwards Processing Relief license.


Inwards Processing Relief is just one customs planning technique of many.

There is no way to know which technique suits your business without first fully understanding the supply chain. As such, we always recommend that if you are considering this project, you take a step back, consider what your project goals are and review all the options available.

The decision as to whether or not Inwards Processing Relief is right for your business will come down to cost (financial and time invested) vs benefit (ongoing savings).

We typically recommend that if the savings are upwards of £30,000 per annum, then it is logical to implement Inwards Processing Relief.


The Inwards Processing Relief Application Process

Capital Projects

The process typically takes 3 months, but in exceptional circumstances, can be applied for with retrospective effect.  The process should look like this:

Draft the necessary document landscape, including audit trails, control of master data, transaction flows, working instructions bolstering your validity within the Inwards Processing field.

Managing HMRC involvement through the process, addressing initial questions on the application, addressing points coming out of their application audit, and reviewing any authorisation to ensure it conforms with HMRC regulation and what you applied for.

Training staff to operate the Inwards Processing and ancillary compliance obligations coming out of the authorisation, including spotting errors, managing business and regulatory changes, etc.

The Ongoing Requirements For Inward Processing Relief


Is This Possible To Do In-House?

The answer to this depends on whether or not you have sufficient in-house expertise and time to manage this complex project. We would strongly recommend that if you do not have expertise within your team who is familiar with setting up IPR, then you take professional advice. There are common mistakes and bear traps to avoid which ensures IPR will have the best bottom-line impact and not cause serious compliance issues going forward.

Our Services

We have helped many clients obtain permission from HMRC to carry out Inwards Processing Relief.  However, obtaining permission to operate Inwards Processing Relief is only one part of a wider project to ensure it is fully optimised, accurate and future proof.  A common mistake made is that businesses only focus on the application and form-filling exercise whilst neglecting the wider project.  This leaves significant exposure with regards to ongoing obligations and usually means the savings obtained are not maximised. Therefore, Barbourne Brook rarely engages in an Inwards Processing Relief project without first completing a Customs Landscape project.
