EAR Revisions Implementing MTCR 2018–2021 Plenary Agreements and Expanding License Exception Eligibility

Mechanism

The Missile Technology Control Regime (MTCR), established in 1987, is a 35-member informal multilateral export-control arrangement governing transfers of rockets, unmanned aerial vehicles, and related equipment/technology capable of delivering weapons of mass destruction (range ≥ 300 km, payload ≥ 500 kg). The MTCR Annex — the controlled-item list — is updated at biannual Technical Experts Meetings (TEMs), but U.S. EAR incorporation of those changes typically lags by 2–5 years as BIS works through rulemaking.

This final rule closes that lag for decisions reached at four TEMs between March 2018 and October 2021:

ECCN changes (15 CFR Part 774)

The DMAZ addition in 1C111 is the substantively new control: DMAZ is an energetic ionic liquid developed as a storable, low-toxicity hydrazine substitute for satellite/missile attitude-control thrusters, and its addition reflects MTCR consensus that it poses equivalent proliferation risk.

License exception expansion (15 CFR Part 740)

Prior to this rule, almost all EAR license exceptions were unavailable for MT-controlled items regardless of destination. The rule restructures Part 740 to:

1. TMP (Temporary Imports/Exports, §740.9): Permits temporary exports/reexports of MT-controlled items for demonstration, test, or servicing to non-D:4/D:5 countries, subject to return requirements. 2. RPL (Replacement Parts, §740.10): Maintains authorisation for one-for-one replacement parts to non-D:4/D:5 destinations. 3. GOV (U.S. Government, §740.11): Clarifies scope limited to official U.S. government transactions. 4. TSU (Technology/Software Unrestricted, §740.13): Expands eligible technology and software with MT exclusions for the most sensitive items. 5. AVS (Aircraft/Vessels, §740.15): New authorization — permits exports of civil manned aircraft components controlled under ECCNs 7A101–7A103 to non-D:4/D:5 countries, removing what had been an anomalous restriction on commercial aviation parts. 6. APR (Additional Permissive Reexports, §740.16): Clarifies reexport permissions for allied governments.

Thirteen license exceptions remain fully unavailable for MT-controlled items (unchanged).

Transition period

In-transit shipments already under way at the rule's December 8, 2023 effective date were given until January 8, 2024 to clear.

Context

This filing is one of three BIS final rules published in parallel in December 2023 easing EAR licensing requirements in distinct domains. The companion rules addressed AUKUS-related Australia/UK Country Group D:5 rebalancing (see 2024-04-19-us-bis-aukus-ear-export-control-revisions) and allied-government Australia Group biological/chemical controls.

The multi-year lag between MTCR TEM decisions (2018–2021) and EAR codification (2023) is typical of BIS rulemaking timelines and reflects the administrative burden of translating multilateral technical language into U.S. regulatory text. The 2018/2019 TEM changes are now being codified roughly five years after agreement — a pattern BIS has committed to shortening via Advance Notice of Proposed Rulemaking processes.

Downstream implications

• Defence/aerospace exporters serving allied governments (NATO, Japan, Australia, South Korea)

will see reduced EAR licensing overhead for MTCR-controlled components in aircraft and missile sub-systems — approximately 400 fewer license applications annually per BIS estimates.

• DMAZ suppliers should review whether existing authorisations cover ongoing shipments

under the new 1C111 control; existing contracts may require amended licenses.

• D:4 (missile-technology concern) and D:5 (arms embargo) countries remain excluded from

all new exception eligibility — no net liberalisation for China, Iran, Russia, North Korea, or other controlled destinations.

Open questions

• Whether BIS will accelerate codification of subsequent MTCR TEM decisions (2022–2024

plenary outcomes) given the established rulemaking template.

• Impact on U.S. commercial space launch sector: the AVS exception expansion for 7A101–7A103

civil aircraft components may interact with the EAR's space-launch vehicle controls in ways not yet fully tested by exporters.
