This report on Hungnam Fertiliser Complex is the fourth Project Anthracite site profile exploring different chemical production facilities throughout North Korea. The paper provides an assessment of both the chemicals produced on site for their relevance to a potential chemical weapons programme, and whether and how the site would be declarable under the Chemical Weapons Convention (CWC).

Executive Summary

Project Anthracite uses open source information to map out the North Korean chemical industry and its potential links to a chemical weapons programme. The bulk of available information about the Hungnam Fertiliser Complex refers to the production of fertilisers using basic raw materials such as coal, air, water/steam and phosphate ore. Additionally, there is limited information suggesting the site has been used to produce chemical warfare agents (CWAs).

This paper gives a very brief history of the site before going into greater detail around the different areas of the site and the processes that are understood to take place. The paper then provides an assessment of both the chemicals produced on site for their relevance to a potential chemical weapons programme, and whether and how the site would be declarable under the Chemical Weapons Convention (CWC), should North Korea sign and ratify the CWC.

The features and areas of the site are consistent with the large-scale production of fertilisers. The basic raw materials are used to manufacture chemicals including nitrogen, oxygen, carbon dioxide, ammonia and hydrogen, which are in turn used in the production of urea, ammonium nitrate, ammonium phosphate and superphosphate. These are all fertilisers.

While there were no indictors that CWAs are produced on the site, there are several chemicals which are produced on site and which can be used in upstream processes to produce precursors for CWAs.
