Using an average rate of duty to calculate duty relief
Information on using an average rate of duty to calculate duty relief.
The average rate is calculated as a percentage of the of the value of goods for duty as opposed to the total customs import value. The rate will be set for a period not exceeding 12 months (preferably for a calendar year), based on either:
- an approximate estimate made in advance, of the duty payable for that period
- the duty actually paid during a previous 12-month period, adjusted to take account of changes in duty rates
