ISO 17025 accreditation in Nigeria at a glance
In Nigeria, ISO/IEC 17025 is asked for by buyers and schemes rather than required by law. The drivers below show where the pressure comes from.
Nigeria's laboratories are accredited, not certified, and the Nigeria National Accreditation System is the national body that does it. Global ACI shows it recognised for testing and calibration under ISO/IEC 17025 and for medical testing under ISO 15189, each from October 2025, so a laboratory can obtain a locally issued accreditation that overseas buyers can recognise. The Standards Organisation of Nigeria's powers include organising tests and ensuring reference standards for calibration, NAFDAC's registration process depends on laboratory analysis and customers in oil and gas and automotive supply chains set their own acceptance rules. Accreditation is not a certificate, and Sterling cannot grant it. Sterling's Lagos office helps laboratories document the quality system, validate methods, estimate measurement uncertainty and prepare for assessment, with Effivity software and Sterling Academy training included with the engagement.
Who needs ISO 17025 in Nigeria, and what happens without it
In Nigeria the question rarely comes from a law. It comes from the buyer, the regulator or the partner that wants proof before it signs. These are the organisations that get asked.
- Testing laboratories serving food, pharmaceutical and consumer-goods makersCustomers and regulators weigh reports more heavily when they come from an accredited laboratory, and NAFDAC registers the products those laboratories test.
- Calibration and metrology laboratoriesSON's mandate includes maintaining reference standards for calibration, and industry buys calibration traceable to accredited sources.
- Environmental, water and materials testing laboratoriesPermits, audits and customer specifications depend on defensible results.
- Laboratories serving oil and gas, construction and automotive customersOperators and assemblers set their own acceptance rules for test and calibration data.
- In-house quality control laboratories of manufacturersExport customers ask for results from competent laboratories, accredited or not.

Strip away the vocabulary and ISO/IEC 17025 requires a laboratory to prove six things about its competence and the results it reports.
In Nigeria these six sit alongside the local laws and regulations listed under drivers below; one system can evidence both. The detail is on the global hub: ISO/IEC 17025 explained →
How to get ISO 17025 accreditation in Nigeria
One team from the Lagos office carries the work from scoping to accreditation. Clients across Nigeria are served from Sterling's Lagos office, on-site where the work needs it and remotely otherwise.
- Discovery call and scopeEntities, locations, regulators and target date, agreed before any proposal.
- Gap assessment against ISO/IEC 17025 and the Nigerian requirements that apply to youControls you already run for your regulators and customers are reused, not rebuilt.
- Your system built with your team in EffivityRisks, controls, evidence, incidents and reviews in one live system the auditor can see.
- Internal audit, management review and corrective actionsYour internal auditors trained by Sterling; the evidence proven before any external review.
- The accreditation body assessmentThe accreditation body assesses and decides. Sterling supports the assessment.
- End to end, from one team
- Effivity ISO & GRC software
- Preferential Sterling Academy access, with complimentary awareness training for your people
- Internal auditor training for your audit team, as applicable to your standard
- Vulnerability assessment on ISMS engagements
The Sterling Promise: 100% on-time completion, 100% success, 8,100+ client engagements.Sterling does not certify. Certification decisions stay with independent bodies.
How long does ISO 17025 accreditation take in Nigeria?
There is no standard duration: it depends on your scope and on how much of the system already runs. In Nigeria these are the factors that set the timeline.
- Scope of tests and calibrations to be accredited
- Method validation, verification and measurement uncertainty evidence
- Traceability of reference standards and equipment
- Proficiency testing participation and accreditation body scheduling
Sterling agrees a dated plan with you on the discovery call, once the scope is known.
How much does ISO 17025 accreditation cost in Nigeria?
The cost has two parts: the consulting work to build and prove the system, and the accreditation body’s fees, which are quoted separately. In Nigeria these factors move both.
- Number of methods, matrices and ranges in scope
- Equipment calibration and reference materials
- Accreditation body application and assessment fees, quoted by the body and separate from consulting
- Environmental control and facility upgrades
Sterling gives one customised, all-inclusive proposal after the discovery call, never before the scope is agreed.
ISO 17025 consultants and assessors in Nigeria
Two different organisations are involved. A consultant helps you build the system and prove it works; the accreditation body then audits or assesses it and decides. Keeping the two separate is what makes the result credible to buyers and regulators.
- Check that the body’s accreditation or approval covers ISO 17025 and your sector, and that its certificates can be verified online.
- Ask the consultant how the local requirements in Nigeria are mapped into the same system, so nothing runs twice.
- Ask for client references in your sector; Sterling’s client letters are available on request.
- Agree who owns the evidence and the tool after the engagement; with Sterling the system stays yours, in Effivity.

Accreditation, audit language and remote audits in Nigeria
Laboratory competence is recognised by accreditation, not certification. The Nigeria National Accreditation System assesses a laboratory against ISO/IEC 17025 and accredits it for a defined scope, and Global ACI shows it recognised for testing and calibration from October 2025. Neither Sterling nor a certification body accredits laboratories. Apply to the accreditation body for the scope you need and read its published requirements first. Edition and transition details: ISO/IEC 17025 hub →
Audit language
English is the usual audit and document language; agree it with the certification body at application, and say early if interviews will run in another language.
Remote and on-site
Assessments examine the laboratory, equipment and records on-site; document review, method validation files and some witnessing preparation can be handled remotely.
ISO 17025 in Nigeria: questions clients ask
Who accredits laboratories in Nigeria?
The Nigeria National Accreditation System, which describes itself as the national accreditation body for conformity assessment bodies. Global ACI shows it recognised for testing and calibration under ISO/IEC 17025 and for medical testing, each from October 2025. Sterling does not accredit laboratories. Confirm the scope you need with the accreditation body before you plan.
Is ISO 17025 accreditation the same as ISO 9001 certification?
No. ISO 9001 certifies a management system, while ISO/IEC 17025 accreditation confirms that a laboratory is technically competent to produce valid results for specific tests or calibrations. A laboratory may hold both, but only accreditation speaks to technical competence. Ask your customers which one they require for the work you do.
Does NAFDAC accept reports from accredited laboratories?
NAFDAC's registration process includes laboratory analysis, and the Agency decides which analyses it needs and from whom. Its published pages do not make accreditation of a third-party laboratory the sole route. Accreditation still helps credibility with customers and overseas buyers. Ask NAFDAC what it accepts for your product category.
What do assessors look at first?
Method validation, measurement uncertainty and traceability, because accreditation rests on proof that results are valid and linked to reference standards. Proficiency testing results and the competence records of staff follow. Start by listing every method in the intended scope with its validation evidence, and close gaps method by method.
