Nigeria folds SONCAP into the single window, moving certification and clearance checks online
From March 2026, Form M, certification applications and clearance checks are handled through the single window, and the import supervision fee becomes a baseline charge on FOB value.

Key points
- SONCAP keeps its three steps: exporters obtain the product certificate (PC), importers apply for Form M with it, and the shipment certificate (SC) is issued before shipping.
- The import supervision fee was replaced by an FOB-based levy.
- Most construction machinery falls under the controlled list, so include certification lead time and cost in the quote and state who is responsible in the contract.
