Imports of firearms into the UK are controlled in line with the UK’s domestic legislation on the possession of firearms. This ensures that those who do not have authority to possess firearms cannot import them.
The Import Case Management System (ICMS) system allows importers of goods, to make completely electronic applications for import licences, subject to Department for Business, Innovation & Skills (BIS) Import Licensing Branch import controls. This should reduce the administrative burdens on business, making it easier for them to apply. It should also speed up the time it takes to receive an import licence.
You can apply for a new import licence at www.ilb.bis.gov.uk. You need to register on the system before you can use it, see How Do I Register for Import Licences?.
