Examining the Effect of Dumping of Imported Goods on Domestic Producers in the Nigerian Plastics Industry

This study examines the effects of dumping of imported plastic goods on the competitive position and survival of domestic producers in Nigeria's plastics manufacturing industry. Dumping, defined as the sale of goods in a foreign market at prices below their cost of production or home market price, has been documented as a persistent challenge for Nigerian manufacturers of plastic packaging, household utensils, and construction piping, particularly from Asian exporters. The study adopts a descriptive survey research design, collecting data from 85 plastics manufacturing firm managers and workers across industrial estates in Lagos, Ogun, and Anambra states through structured questionnaires. Secondary data on import volumes, unit prices, and domestic production statistics are sourced from the Nigerian Customs Service and the Manufacturers Association of Nigeria. Descriptive statistics and regression analysis are applied. The theoretical framework draws on the unfair trade practices literature and the infant industry protection argument. The study evaluates how dumped imports affect domestic production capacity utilisation, employment levels, and firm profitability, and investigates whether affected firms have sought anti-dumping protection through the Federal Ministry of Finance. Findings are expected to reveal that widespread dumping has significantly reduced capacity utilisation and forced several domestic plastics manufacturers to downsize, yet few firms have utilised anti-dumping trade remedy procedures due to lack of awareness. Recommendations include establishing a dedicated Nigerian trade remedies authority with clear anti-dumping investigation procedures, stakeholder awareness campaigns for affected industries, and proactive engagement with the WTO dispute settlement system.
