Mass retirement exercise raises questions over succession planning, manpower replacement, and the future leadership structure of the Nigeria Customs Service as over 1,500 officers prepare to leave within two years.
By John Ishaku – June 22, 2026
ABUJA, Nigeria – The Nigeria Customs Service (NCS) is preparing for one of the most significant personnel exits in its history, with no fewer than 1,516 officers scheduled for statutory retirement between 2026 and 2027.
Internal documents obtained by A1NEWS International reveal that the impending retirements will affect officers across virtually every cadre of the Service, including five Deputy Comptrollers-General (DCGs), Assistant Comptrollers-General (ACGs), Comptrollers, Superintendents, Inspectors, and junior personnel.
The development comes at a critical period for the Customs Service, which is implementing major reforms under the leadership of Comptroller-General of Customs, Adewale Adeniyi, whose tenure was recently extended by President Bola Ahmed Tinubu.
While authorities insist the retirements are routine and in line with civil service regulations, the scale of the exercise has sparked discussions about succession planning, institutional memory, manpower shortages, and the Service’s preparedness to fill critical vacancies.
Internal Circulars Reveal Scale of Exit
The retirement exercise is contained in two separate internal circulars issued by the Human Resource Development Department of the Nigeria Customs Service.
The documents, signed by Comptroller of Establishment, A.A. Bazuaye, on behalf of the Deputy Comptroller-General in charge of Human Resources and Development, outline retirement schedules for officers due to exit in 2026 and 2027.
The first circular, identified as HRD/2025/048 and dated September 19, 2025, contains the final list of 825 officers scheduled for retirement in 2026.
A second circular, HRD/2026/020 dated May 26, 2026, presents a draft list of 691 officers expected to retire in 2027.
Combined, the two exercises will see 1,516 officers leave active service within a 24-month period.
Five Deputy Comptrollers-General Among Senior Officers Exiting
Among the most notable retirements are five Deputy Comptrollers-General, representing some of the highest-ranking officers within the Service.
The affected senior officers include:
- DCG Omale
- DCG Nnadi
- DCG Chiroma
- DCG Adeola
- DCG Niagwan
Several Assistant Comptrollers-General are also listed for retirement, creating potential vacancies within the upper echelons of Customs management.
Industry observers note that the retirement of officers at such senior levels could trigger significant leadership realignments across operational, administrative, and enforcement commands nationwide.
Superintendent and Deputy Superintendent Cadres Most Affected
Analysis of the retirement lists indicates that middle-management cadres will bear the greatest impact.
For the 2026 retirement exercise:
- Deputy Superintendent of Customs – 285 officers
- Superintendent of Customs – 226 officers
- Assistant Superintendent I – 64 officers
- Chief Superintendent – 61 officers
- Chief Customs Officer – 53 officers
- Deputy Customs Officer – 51 officers
- Assistant Customs Officer – 46 officers
For 2027:
- Superintendent of Customs – 200 officers
- Deputy Superintendent of Customs – 193 officers
- Deputy Customs Officer – 81 officers
- Chief Superintendent – 68 officers
- Assistant Customs Officer – 57 officers
The figures suggest that a substantial portion of the Service’s supervisory and operational workforce will be exiting within a short period.
Mandatory Retirement Leave Activated
In accordance with Public Service Rule 100238 and relevant Federal Government directives, all affected officers have been instructed to commence mandatory pre-retirement leave three months before their effective retirement dates.
The circulars directed officers to submit retirement notices to the Comptroller-General and complete all necessary disengagement procedures.
The Service also instructed Zonal Coordinators, Area Controllers, and Unit Heads to ensure the retirement notices are properly communicated to all affected personnel.
Questions Over Replacement Strategy
One of the major concerns emerging from the retirement exercise is whether the Customs Service possesses adequate manpower replacement mechanisms.
With over 1,500 officers expected to leave within two years, experts warn that recruitment, promotion exercises, and capacity-building programmes must be accelerated to prevent operational gaps.
Efforts by A1NEWS International to obtain official clarification regarding replacement plans and recruitment projections were unsuccessful at the time of filing this report.
The Service’s spokesperson had yet to issue a formal response on how the vacancies would be addressed.
Lawmaker Dismisses Succession Speculation
Amid growing speculation linking the retirements to ongoing leadership discussions within the Customs Service, Chairman of the House of Representatives Committee on Customs and Excise, Hon. Abejide Leke Joseph, dismissed such claims.
The lawmaker described the retirements as routine and legally mandated under existing public service regulations.
According to him, officers are required to retire upon attaining 60 years of age or completing 35 years in service.
He stressed that no officer was being forced out to pave the way for any anticipated appointment or succession arrangement.
“The Civil Service Rules are very clear. Retirement after 35 years in service or at the age of 60 is not by compulsion; it is by law,” he stated.
Recruitment Gap Behind Retirement Surge
Providing further insight into the unusually high number of retirements, Abejide pointed to a prolonged recruitment gap within the Customs Service.
According to him, approximately 16 years of limited recruitment and delayed promotions created a situation where many officers progressed through the ranks simultaneously.
As a result, officers with service numbers in the 41000, 42000, and 43000 series have reached retirement eligibility around the same period.
The consequence, analysts say, is a “retirement bulge” that has concentrated departures within a narrow timeframe.
Tinubu Extends Adeniyi’s Tenure
The retirement exercise coincides with President Bola Tinubu’s approval of a final six-month extension for Comptroller-General Adewale Adeniyi.
The extension allows Adeniyi to remain in office until February 2027.
According to the Presidency, the decision was made to enable the Customs boss complete critical reforms, including implementation of the National Single Window initiative and supervision of key personnel matters.
The extension is also expected to facilitate orderly succession planning and ensure promotions and retirements are managed without disrupting operations.
Implications for Customs Operations
The impending exit of more than 1,500 officers presents both challenges and opportunities for the Nigeria Customs Service.
While the retirements create room for promotion and career progression among younger officers, they also pose risks associated with the loss of institutional knowledge and experienced personnel.
Experts believe the Service must balance succession planning with strategic recruitment, training, and modernization efforts to sustain operational efficiency.
With Customs remaining central to revenue generation, trade facilitation, border security, and anti-smuggling operations, stakeholders will be closely monitoring how the Service manages the transition.
The retirement of 1,516 officers, including five Deputy Comptrollers-General, marks a defining moment in the history of the Nigeria Customs Service. Although authorities maintain that the exercise is purely statutory, its unprecedented scale underscores the importance of succession planning, workforce renewal, and institutional continuity.
As the Service prepares for a major generational shift, attention is now turning to how quickly vacancies will be filled and whether ongoing reforms can be sustained amid one of the largest personnel transitions ever witnessed within the agency.
