HMRC internal manual

Holding and Movements - Financial Securities Assurance

Movement guarantees: What levels do we require for a movement guarantee?

You should normally set the following levels:

Potential duty on an average week’s movements Level of security
<£1m 25% of potential duty
>£1m but <£25m £250,000
>£25m but <£100m 1% of potential duty
>£100m £1m

In all cases you may demand a security higher than that shown in the above bandingsincluding, if necessary, a guarantee of more than £1m. You may also require traders toprovide a guarantee that would cover the maximum amount of duty suspended in a singlemovement. For example, you could require a guarantee of £30,000 where this is the amountof duty suspended on a single movement even if the Principal meets the criteria for alower level of guarantee.

You should also note that duty representatives (registered under WOWG 1999 to act onbehalf of non-UK owners of warehoused goods) cannot provide movement guarantees.
