Smuggling as Rational Adaptation: Rethinking Customs Enforcement and Informality in Zambia: A Case Study for ZRA

Goods smuggling remains a major challenge in Zambia, reducing government revenue, distorting markets, and weakening regulatory systems. Despite efforts by the Zambia Revenue Authority (ZRA), smuggling persists due to policy gaps, socio-economic pressures, and weak enforcement. This study develops a conceptual model linking customs enforcement, socio-economic drivers, and tax policy structures to explain smuggling dynamics. A qualitative case study design was employed, focusing on Chirundu border town. Data were collected through in-depth interviews and focus group discussions with customs officials, traders, and community members, and analysed using thematic analysis. Findings indicate that smuggling is driven by interacting economic and institutional incentives rather than enforcement failure alone. High import duties, complex compliance procedures, and regulatory burdens encourage traders to bypass formal systems, while unemployment and dependence on informal trade reinforce such behaviour. Weak enforcement capacity, resource constraints, and corruption further reduce the perceived risk of detection. The study proposes an integrated anti-smuggling model that conceptualizes smuggling as a rational response to systemic conditions. It recommends policy reforms including risk-based monitoring, digital tracking systems, tax simplification, improved institutional coordination, and support for formalizing informal trade.
