The Comptroller-General of the Nigeria Customs Service, Adewale Adeniyi, says import duty exemption certificate approvals reached ₦34 trillion in 2025, describing the policy as a major factor limiting the agency's revenue generation.

Speaking during an investigative session of the Senate Committee on Finance with revenue-generating agencies in Abuja, Adeniyi said government fiscal policies have continued to affect the revenue performance of the Nigeria Customs Service, both positively and negatively.

He explained that the Import Duty Exemption Certificate scheme, introduced in March 2020, accounted for about ₦34 trillion in approvals in 2025, with nearly 60 per cent of the approvals covering duty-free importation of military hardware to address Nigeria's security challenges.
