NEW BIS LICENSE TYPES C65 – (TGL) TEMPORARY GENERAL LICENSE and C66 – (SCAL) SUPPLY CHAIN AUTHORIZATION LETTER

Plain-English explanation

CSMS 55500894 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on March 15, 2023. It carries the official CBP guidance brokers and importers must follow for the topic — "NEW BIS LICENSE TYPES C65 – (TGL) TEMPORARY GENERAL LICENSE and C66 – (SCAL) SUPPLY CHAIN AUTHORIZATION LETTER". CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

CSMS # 55500894 - NEW BIS LICENSE TYPES C65 – (TGL) TEMPORARY GENERAL LICENSE and C66 – (SCAL) SUPPLY CHAIN AUTHORIZATION LETTER U.S. Customs and Border Protection sent this bulletin at 03/15/2023 12:39 PM EDT   Cargo Systems Messaging Service CSMS # 55500894 - NEW BIS LICENSE TYPES C65 – (TGL) TEMPORARY GENERAL LICENSE and C66 – (SCAL) SUPPLY CHAIN AUTHORIZATION LETTER In the Automated Export System (AES), Customs and Border Protection (CBP) has activated new BIS License Types C65 – (TGL) TEMPORARY GENERAL LICENSE and C66 – (SCAL) SUPPLY CHAIN AUTHORIZATION LETTER. On October 13, 2022, the Department of Commerce, Bureau of Industry and Security (BIS) published an interim final rule (https://www.govinfo.gov/content/pkg/FR-2022-10-13/pdf/2022-21658.pdf) that became effective October 7, 2022.  Among other actions, this interim final rule established a new Temporary General License to avoid disruption of supply chains for certain items that are ultimately destined to customers outside of People’s Republic of China (China) or Macau.  In a separate series of actions, the BIS Deputy Assistant Secretary for Export Administration issued a number of Supply Chain Authorization Letters which describe specific authorizations granted pursuant to requests based on exigent circumstances of actual or potential supply chain disruptions. As a result of these actions, the following change will be made to the Automated Export System (AES) in order for exporters and authorized agents to successfully report electronic export information in the AES. New License Code C65 (TGL) An update has been made to AES to create new License Codes C65 “Temporary General License” (TGL), which authorizes certain exports, reexports, in-country transfers, and exports from abroad destined to or within China or Macau by companies not headquartered in Country Groups D:1 or D:5 or E (see supplement no. 1 to part 740 of the EAR) to continue or engage in integration, assembly (mounting), inspection, testing, quality assurance, and distribution of items covered by ECCN 3A090, 4A090, and associated software and technology in ECCN 3D001, 3E001, 4D090, or 4E001; or any item that is a computer, integrated circuit, “electronic assembly” or “component” and associated software and technology, specified elsewhere on Commerce Control List (supplement no. 1 to part 774), which meets or exceeds the performance parameters of ECCN 3A090 or 4A090.  The full terms of this Temporary General License are described in General Order No. 4 of in paragraph (d) in supplement no. 1 to part 736 of the EAR. AES filers must adhere to the following new reporting when using C65 (TGL) to prevent the return of fatal errors from AES. Report License Code: C65 Temporary General License (TGL) Allowable ECCNs: 3A090, 4A090, 3D001, 3E001, 4D090, 4E001, or any item that is a computer, integrated circuit, “electronic assembly” or “component” and associated software and technology, specified elsewhere on Commerce Control List (supplement no. 1 to part 774), which meets or exceeds the performance parameters of ECCN 3A090 or 4A090. Allowable Export Information Codes: All except UG Allowable Modes of Transportation: All except ‘70’ (Fixed Transport) Please refer to “General Order No. 4” in paragraph (d) in supplement no. 1 to part 736 of the EAR for additional requirements for this Temporary General License. This does not authorize the export, reexport, in-country transfer, or export from abroad to “end-users” or “ultimate consignees” in China or Macau. This Temporary General License does not overcome the license requirements of §§ 744.11 or 744.21 when an entity listed in supplements no. 4 or 7 to part 744 is a party to the transaction as described in § 748.5(c) through (f) of the EAR, or when there is knowledge of any other prohibited end use or end user. This Temporary General License is only for companies that engage in the specific activities authorized under this Temporary General License.  This Temporary General License and its associated License Code (TGL) are valid for use through April 7, 2023. New License Code C66 (SCAL) An update has been made to AES to create License Type Code C66 “Supply Chain Authorization Letter” (SCAL).  The BIS Deputy Assistant Secretary for Export Administration issued a number of such letters in response to specific requests based on exigent circumstances of actual or potential supply chain disruptions. Recipients of Supply Chain Authorization Letters must comply with the specific terms issued by BIS in such letters.  A Supply Chain Authorization Letter is only valid for use by the original recipient of the letter or by parties authorized therein. AES filers must adhere to the following new reporting when using C66 (SCAL) to prevent the return of fatal errors from AES.  Supply Chain Authorization Letter Report License Code: C65 Supply Chain Authorization Letter (SCAL) Allowable ECCNs: All, including EAR99. Allowable Export Information Codes: All except UG Allowable Modes of Transportation: All except ‘70’ (Fixed Transport) A complete list of all of the AES License Codes and reporting instructions for these types can be found at:   AESTIR Appendix F - License and License Exemption Type Codes | U.S. Customs and Border Protection (cbp.gov) For technical questions, Software Vendors should contact their respective Client Representative.

Frequently asked questions

What is CSMS 55500894?

CSMS 55500894 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "NEW BIS LICENSE TYPES C65 – (TGL) TEMPORARY GENERAL LICENSE and C66 – (SCAL) SUPPLY CHAIN AUTHORIZATION LETTER". CSMS bulletins are the operational instructions CBP issues to brokers, importers, and ACE filers covering rate changes, system updates, scope guidance, and other day-to-day customs-operations changes.

When was CSMS 55500894 published?

CBP published CSMS 55500894 on March 15, 2023. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Is the CBP CSMS the legally binding instruction?

Yes — for at-the-border filing and entry collection. CSMS messages translate Commerce's Federal Register determinations into operational CBP instructions that ACE/ACS systems and brokers execute. The Federal Register notice is the underlying legal authority; the CSMS is the operational implementation. Both should be read together when reconciling a rate or scope change.
