This chapter attempts to reconstruct and detail the country's defence-export catalogue. It discusses North Korea's pricing decisions, as well as its arms-marketing methods and tools, and as a point of comparison to what Pyongyang has on offer, its competitors. Commentators that seek to explain a particular country's military relationship with North Korea frequently conclude that cost is a primary factor determining a foreign partner's interest in buying from Pyongyang. North Korea has unique challenges in attracting custom as a result of the national and UN sanctions against it, its international reputation, and the international political influence of its adversaries, including the US and South Korea. The chapter lays the ground for the ensuing exploration of which states and non-state actors have bought arms and related materiel and services from North Korea in the sanctions era, what they have bought, and why.
