Article 2 of that order, by way of an exception to this prohibition, permits the importation of goods into the United Kingdom under the authority of a licence. This Licence allows the importation of all goods into the United Kingdom, subject to the exceptions which it sets out.

Interpretation

2. In this licence:

“ammunition” has the same meaning given to that term in both:

  • Article 2(2) of the Firearms (Northern Ireland) Order 2004 in relation to Northern Ireland
  • Section 57(2) of the Firearms Act 1968 in relation to Great Britain

“the Convention” means the Convention on the Prohibition of the Development, Production, Stockpiling and use of Chemical Weapons and on their Destruction, signed at Paris on 13 January 1993.

“the Goods Classification Table” means the table so named in Annex I in Part Three of the Tariff of the United Kingdom.

“the Tariff of the United Kingdom” means the document containing the legal classification and import rate for products being imported into the United Kingdom, entitled “The Tariff of the United Kingdom”, as revised or re-issued from time to time.

HN2 Salts

Salts of bis(2-chloroethyl)methylamine (CAS 51-75-2) may be exempted if their product forms meet all of the following criteria:

  • are pharmaceutical formulations designed for human or animal administration in the treatment of medical or veterinary conditions, or in authorised clinical trials for such treatment; and
  • are authorised by the relevant regulatory authority to be marketed as clinical, medical or veterinary products, used in authorised clinical trials, or prescribed by a physician or veterinarian

This specific exemption will only apply when the named chemicals are held in quantities consistent with the end-use described.

Saxitoxin

Saxitoxin free base (CAS 35523-89-8) and its corresponding salts, in addition to their isotopically labelled analogues and stereoisomers, may be exempted if one or all of the following criteria are met:

  • it is an essential component (standard solution) of commercial antibody-based rapid test kits, or is a stand-alone certified calibration solution/solid
  • it is to be used specifically for purposes related to paralytic shellfish poisoning testing, including related research and international proficiency testing activities

This specific exemption will only apply when the named chemicals are held in quantities consistent with the end-use described.

Ricin

Ricin (CAS 9009-86-3), ricin A chain (CAS 96638-28-7) and their isotopically labelled analogues may be exempted if they are toxoids.

Samples

Transfer, possession and use of clinical and veterinary samples (such as blood, urine, saliva and tissue) and environmental samples (such as clothing, equipment or soil) may be exempted if they meet all of the following criteria:

  • have no visible contamination; and
  • are to be used for legitimate medical, analytical or research purposes, or are to be destroyed

It is a breach of the Chemical Weapons Act 1996 to acquire, produce, possess or use a CWC Schedule 1 chemical without an appropriate licence issued by the UK National Authority. If you are in any doubt as to whether your activities require a CWC Schedule 1 licence, please contact the UK National Authority immediately for further guidance and advice.

The exemptions are current as of December 2019, will be kept under review and may be subject to change in the future.

Annex 4: UK marking requirements

A. Marking requirements that apply on the importation of firearms and any relevant component parts into the United Kingdom

  1. Entry 5 of Annex 1 prohibits, subject to specified exclusions, the importation or transfer into the United Kingdom of firearms and any relevant component parts (whether part of a firearm or not), unless each such firearm, and any relevant component parts, have clearly and permanently been marked with the relevant information specified below, and set out for Great Britain, in paragraph 2(aa) of Part IV to Schedule 5 of the Firearms Rules 1998, or for Northern Ireland, in Para. 6 (b), of Schedule 3 to the Firearms (Northern Ireland) Order 2004.

  2. This prohibition does not apply to:

(a) firearms and any relevant component parts imported or transferred into the United Kingdom, pursuant to a specific import licence on condition that they are so marked within 28 days of their importation

(b) firearms imported for deactivation provided the importer has been granted a specific import licence in respect of the firearm and/or relevant component part conditional on that firearm and/or relevant component being deactivated within 3 months from the date of importation into the UK

(c) as regards imports into Northern Ireland, firearms and relevant component parts manufactured anywhere in the European Union before 14 September 2018 or which were imported into the European Union before that date

3. The unique marking referred to in paragraph 1, applicable on importation:

(a) into Great Britain in the case of firearms and relevant component parts (other than air weapons and firearms of historical importance)

(b) into Northern Ireland in the case of firearms and relevant component parts (other than firearms of historical importance) manufactured anywhere in the European Union or imported from outside the European Union on or after 14 September 2018 shall include:

(i) the calibre

(ii) the name of the manufacturer or brand

(iii) the country or place of manufacture

(iv) the serial number and year of manufacture (if not part of the serial number)

(v) the model (where feasible)

(vi) where a relevant component part, other than the frame and the receiver, is too small to have a unique marking including all of the information set out in paragraph (i) to (v) above, the serial number or alphanumeric or digital code instead of that information

B. Implementation of technical specifications for the marking of firearms and their essential components:

  1. The font size to be used in the marking shall be at least 1.6 mm unless the relevant component parts that are too small to be marked to this size, in which case a smaller font size may be used.
  2. For frames or receivers made from a non-metallic material, the marking should be applied to a metal plate that is permanently embedded in the material of the frame or receiver in such a way that the plate cannot be easily or readily removed; and removing the plate would destroy a portion of the frame or receiver. Other techniques for marking such frames or receivers are permitted, provided that importers can demonstrate that those techniques ensure an equivalent level of clarity and permanence for the marking.
  3. The alphabet used in the marking of imported firearms or relevant component parts shall be Latin, Cyrillic or Greek and the numeral system used in the marking shall be Arabic or Roman. Where an import licence requires firearms or relevant component parts to be marked within 28 days after importation into the UK, or within 3 months if imported to be permanently deactivated such goods shall be marked in the Latin alphabet and the Arabic numeral system.
