In August 2026, the Standards Organisation of Nigeria (SON) officially introduced the SONMELS mandatory energy labeling scheme. Air conditioners must meet minimum energy performance standards before entering the market. The first phase covers portable and split ACs, with full enforcement starting December 2026. Unlabeled products will be denied customs clearance. For assemblers targeting the West African market, this means BOM adjustments are required to ensure compressors and system matching meet local efficiency testing protocols, or face port delays.
