ITAR vs EAR for Aerospace & Defense Suppliers: What You Need to Know

Introduction

For aerospace and defense suppliers, export control compliance is a critical requirement—but also one of the most commonly misunderstood.

Many companies receive contracts referencing ITAR or EAR requirements without a clear understanding of:

• which regulations apply

• what controls are required

• how these obligations affect contracts and operations

This article explains the differences between ITAR and EAR and how suppliers typically address these requirements in practice.

What Are ITAR and EAR?

Export controls in the United States are governed primarily by two regulatory frameworks:

ITAR (International Traffic in Arms Regulations)

• Applies to defense-related articles, services, and technical data

• Administered by the U.S. Department of State

• Covers items listed on the U.S. Munitions List (USML)

EAR (Export Administration Regulations)

• Applies to dual-use items (commercial + military applications)

• Administered by the U.S. Department of Commerce

• Covers items listed on the Commerce Control List (CCL)

Key Differences Between ITAR and EAR

Category ITAR EAR

Scope Defense-specific Dual-use (commercial + defense)

Regulator Department of State Department of Commerce

Control Level Generally stricter Varies by classification

Licensing Often required Depends on classification and destination

Why This Matters for Suppliers

Export control requirements can affect:

Contract obligations

• Suppliers may be required to comply with ITAR or EAR clauses flowed down from prime contracts

Access to technical data

Restrictions may apply to:

• drawings

• specifications

• engineering data

Workforce considerations

• Access by foreign persons may be restricted

Data handling and transfers

Controls may apply to:

• digital data

• cloud storage

• communications

How Export Controls Show Up in Contracts

In aerospace and defense agreements, export control requirements are often included through:

• contract clauses

• purchase order terms

• supplier agreements

• flowdown provisions

These may require suppliers to:

• comply with applicable regulations

• restrict access to controlled data

• obtain licenses where required

Common Challenges Suppliers Face

Determining whether ITAR or EAR applies

• Classification may not always be clear

Managing technical data access

• Controlling who can access information can be complex

Integrating export compliance into contracts

• Export requirements must align with procurement and supplier terms

Maintaining documentation

• Proper recordkeeping is essential for compliance

Practical Steps Suppliers Often Take

While specific requirements depend on the contract and program, suppliers commonly:

Identify applicable regulations

• Determine whether ITAR or EAR applies based on contract requirements

Implement access controls

• Limit access to controlled data where required

Align contracts and terms

Ensure export control language is included in:

• supplier agreements

• purchase order terms

Flow down requirements

• Ensure lower-tier suppliers receive applicable obligations

Maintain records

• Document compliance actions and retain required records

A More Structured Approach

Many companies move from a reactive approach to a more standardized system that includes:

• consistent export control clauses

• aligned supplier agreements and PO terms

• integrated FAR/DFARS flowdowns

• defined processes for handling controlled data

This helps improve consistency and reduce compliance risk.

AerocontractsPro Toolkit

To support this, AerocontractsPro includes:

• export control (ITAR/EAR) provisions

• FAR/DFARS flowdown clause library

The toolkit is designed to help suppliers integrate export control requirements into their contracting and procurement processes.

Conclusion

Understanding ITAR and EAR is essential for companies operating in aerospace and defense supply chains.

While the requirements can be complex, a structured approach to contracts and compliance can help organizations manage obligations more effectively and reduce risk.
