Phosphates mined in France’s North African empire fed interwar Europe’s voracious appetite for chemical fertilizers. In critique of histories vesting commodities themselves with the agency to make the modern world, I trace not the substance but the value embedded within it. By following value, I argue that the ‘commodity’ is not a stable unit of analysis. Rather, commodities are multiform. They can acquire myriad properties when the value embedded within them changes across time and place. During the interwar period, phosphates’ character as a commodity transmuted in relation to flows of other goods, movements of labour, global financial exigencies and imperial considerations. As phosphates assumed new forms, the geographic scales over which they operated changed too. Through North African phosphates, I explore value-making processes that perpetuated capital-intensive farming, allowing for a history not of the commodity-as-substance but of the commodity-as-historical-object whose analytical boundaries and forms shifted across contexts.

6 These terms derive from Marx, but I define them more broadly. Use value combines materiality with political and social considerations. Exchange value encompasses both labour time added and socio-political factors that shape prices and profits (colonial wage suppression, French imperial-monopolistic ambitions, financial market instability, etc.). Price influences exchange value, but the two are not synonymous. Finally, use and exchange value can influence each other. When a commodity’s exchange value changes, other uses can become profitable or desirable. When its use value changes, capitalists can harness new competition or collusion, thereby altering exchange value. Karl Marx, Capital: A Critique of Political Economy, trans. Ben Fowkes (New York: Vintage Books, 1977), 1: 125–31.

12 Here, cargo space is a commodity because it had use value and was bought, sold, and bartered. Embedded in it is the labour required for the ship to sail.
