Which ISO Standard Does My Company Need?

Choose an ISO standard for your activities and buyer requirements: quality, environment, workplace safety, food safety and petroleum-sector quality.

Updated 29 September 2026

Choose your ISO standard around your activities, management needs and the buyer’s written requirements. A sector label alone does not determine which certificates you need. If you are new to certification, read our guide to ISO certification cost and process in Iraq.

Match the standard to your activities

Each standard addresses a different management need. These examples help you compare the options; they are not a list of mandatory certificates for each sector. Follow the service link for details.

ISO 9001 or ISO 22000 for a food business?

ISO 9001 addresses quality management. ISO 22000 addresses food safety management, including the control of food safety hazards. A food producer, storage business or distributor should identify which need and customer requirement it is addressing before choosing one standard or a combined programme. The two certificates are not interchangeable.

ISO guidance on quality management and ISO 22000 food safety management.

Combining standards

A company may combine ISO 9001, ISO 14001 and ISO 45001 to manage quality, environmental impacts and workplace safety together. Food businesses may consider ISO 22000, while petroleum supply-chain organizations may consider ISO 29001. Confirm the need for each standard before agreeing the certification scope and audit plan.

Confirm your requirements before starting

Once you know the standard, clarify which activities and sites the certificate should cover before requesting an offer.

Send IraqCert your activities and the buyer’s stated requirements so we can scope the preparation support you need. The independent certification body conducts the certification audit and decides on issuance. ISO 29001 is outside partner body AQSR’s disclosed UAF-accredited scope; we confirm the issuing body and its scope before booking that audit. See our ISO certification services.
