IATF 16949 Certification

IATF 16949 is the quality management standard for automotive suppliers, used worldwide. In practice, many vehicle manufacturers and Tier 1 suppliers require IATF 16949 certification when selecting component suppliers.

What is IATF 16949?

IATF 16949 is published by the International Automotive Task Force (IATF), a group of leading vehicle manufacturers and national automotive trade associations. The current edition, IATF 16949:2016, replaced the former ISO/TS 16949. It is not a stand-alone standard but is applied together with ISO 9001:2015: organisations must meet both the ISO 9001:2015 requirements and the automotive-specific requirements of IATF 16949. The publication of ISO 9001:2026 does not automatically change the requirements of IATF 16949:2016; any changes apply as officially announced by the IATF.

Many vehicle manufacturers require IATF 16949 certification as a condition for a supply relationship. The standard focuses on continual improvement of the system, its processes and ultimately product quality in development and production. Processes are assessed using a risk-based, process-oriented approach in which defect prevention takes top priority, together with the reduction of variation and waste in the supply chain.

Who IATF 16949 applies to

IATF 16949 applies to manufacturing sites of organisations supplying the automotive industry, including:

Manufacturers of parts, assemblies and materials for new vehicle production.
Manufacturers of service parts specified by vehicle manufacturers.
Tier 1, Tier 2 and lower-tier suppliers where their customers require it.

Support functions such as design centres, headquarters or distribution warehouses can be included in the scope as remote support locations, but cannot be certified on their own without a link to a manufacturing site.

Key requirements and core tools

On top of ISO 9001, IATF 16949 adds a range of automotive-specific requirements:

Customer-specific requirements (CSRs) of each vehicle manufacturer must be identified and built into the system.
Product safety, warranty management, embedded software and contingency planning to safeguard continuity of supply.
Supplier development and tight control of externally provided products and processes.
Use of the industry's core tools: Advanced Product Quality Planning (APQP), Production Part Approval Process (PPAP), Failure Mode and Effects Analysis (FMEA), Measurement System Analysis (MSA) and Statistical Process Control (SPC).

Certification under IATF rules

Unlike many ISO standards, IATF 16949 certification is overseen directly by the IATF through its own certification rules (IATF Rules, 6th edition, effective 1 January 2025). Only IATF-recognised certification bodies may issue certificates, and every certificate is registered in the IATF database. Audit duration, surveillance intervals and deadlines for closing nonconformities are all strictly defined. Before the initial certification audit, the organisation must already be operating its system and have completed at least one full cycle of internal audits and management review.

Benefits for your organisation

Wider market access

Meet the automotive industry's common quality requirements, a frequent condition for joining vehicle manufacturers' supply chains.

Fewer defects, lower quality costs

Preventing defects from the design stage can reduce scrap, rework, complaints and warranty costs.

More efficient processes

Standardised development and production can help you cope with rising cost pressure.

Customer confidence

A certificate issued by an IATF-recognised certification body is independent evidence of your automotive quality management system.

How it works

Initial enquiry, definition of scope, manufacturing and support sites, and quotation
Contract signing and an audit plan in line with IATF rules
Stage 1 audit: readiness review for certification
Stage 2 on-site audit: assessing processes using the process and risk-based approach
Closure of nonconformities within set deadlines, independent review and certification decision
Issue of the IATF 16949 certificate and registration in the IATF database
Regular surveillance and recertification audits to keep the certificate valid

Frequently asked questions

How does IATF 16949 differ from ISO 9001?

ISO 9001 is a generic quality management standard for every industry, while IATF 16949 is an automotive-specific standard built on ISO 9001. Organisations applying IATF 16949 must meet all of ISO 9001 plus sector requirements such as product safety, core tools, warranty management and each vehicle manufacturer's specific requirements.

Which core tools do we need to master for IATF 16949?

The five core tools usually referred to are APQP (Advanced Product Quality Planning), PPAP (Production Part Approval Process), FMEA (Failure Mode and Effects Analysis), MSA (Measurement System Analysis) and SPC (Statistical Process Control). Some vehicle manufacturers also prescribe their own methods or manuals in their customer-specific requirements.

How long is an IATF 16949 certificate valid?

The IATF 16949 certification cycle is three years. Within that cycle, the organisation undergoes regular surveillance audits at intervals strictly defined by the IATF Rules. If a major nonconformity is found or corrections are not completed on time, the certificate can be suspended or withdrawn, so the system must be maintained continuously.

Can independent aftermarket parts manufacturers be certified?

IATF 16949 targets the OEM-driven automotive supply chain, covering parts for new vehicles and service parts specified by vehicle manufacturers. Companies that only produce parts for the independent aftermarket, not to a vehicle manufacturer's specification, are generally outside its scope and may consider ISO 9001 certification instead.
