The United States — the world's largest economy at $27 trillion — has one of the most diverse ISO certification landscapes. Unlike most countries where a single national accreditor dominates, the USA has ANAB (ANSI National Accreditation Board) as the primary body, supplemented by the massive federal procurement system (SAM.gov), FDA regulatory requirements for medical devices, DoD DFARS/CMMC for defence, and state-level procurement portals across 50 states.
Why US Businesses Need ISO Certification
- SAM.gov federal procurement — Federal government contracts through SAM.gov and individual agency portals (GSA Schedules, NITAAC, SeaPort-NxG) require ISO 9001 from qualified vendors
- FDA 21 CFR Part 820 / ISO 13485 — Medical device manufacturers must comply with FDA Quality System Regulation — ISO 13485 is the internationally aligned standard and supports FDA 510(k) and PMA submissions
- DoD DFARS / CMMC 2.0 — Department of Defense contracts require ISO 9001; CMMC 2.0 Level 2 aligns with NIST SP 800-171 where ISO 27001 provides a complementary management system
- Healthcare IT (HIPAA + ISO 27001) — HIPAA requires appropriate technical safeguards — ISO 27001 provides the systematic information security management framework demonstrating HIPAA compliance
- Oil and gas (API standards) — American Petroleum Institute standards complement ISO for oil sector; ISO 9001 for vendor qualification
- State and local government procurement — All 50 states have procurement portals requiring ISO from significant contractors
- Corporate supply chains — Fortune 500 companies require ISO 9001 from Tier-1 and Tier-2 suppliers as standard practice
ANAB — US National Accreditation
ANAB (ANSI National Accreditation Board) is the USA's national accreditation body — an IAF-member body. ANAB-accredited ISO certificates are recognized by all US government agencies, FDA, DoD, and globally through IAF MLA. IAF-accredited (but non-ANAB) certificates from international CBs are also accepted for US government procurement. Elite Assured uses ANAB-aligned, IAF CertSearch-listed CBs.
