These coupons were issued by the Controller of Rubber in Sarawak as administrative instruments for managing rubber export quotas during the International Rubber Regulation Agreement period, which imposed strict production ceilings on Malayan and Bornean producers throughout the late 1930s and into 1941. A kati is a unit of weight used across Southeast Asia, roughly equivalent to 1.33 pounds — so this coupon authorized export of a fairly small parcel, suggesting it was designed for use by smallholders rather than large estate operators.
Printing by the Survey Department, Federated Malay States, is notable: that office primarily produced maps and administrative forms, not currency or financial instruments. The watermarked paper elevates it above a purely clerical document.
