What This ECCN Covers

ECCN 3A003 controls spray cooling thermal management systems that use closed-loop fluid handling and reconditioning in a sealed enclosure, meeting the entry's criteria. These advanced cooling systems support high-power electronics and are controlled for National Security and Anti-Terrorism reasons.

Who needs to check this?

Makers of advanced thermal-management and two-phase/spray cooling systems for high-power electronics, radar, and computing hardware.

Compliance tip

Control is specific to closed-loop spray-cooling systems with the characteristics in the entry — ordinary liquid cooling falls outside. Confirm your system against the entry, and check the NS and AT Country Chart columns before relying on a license exception.
