The Myanmar Investment Commission (MIC) has issued a notification that gives investors with projects in Myanmar clearer guidance for securing approval and for changing, expanding, or exiting an approved project. Issued on August 19, 2026, MIC Notification No. 5/2026 replaces MIC Notification No. 26/2021 and sets procedures for state or regional investment committees to review, approve, and supervise investment projects, including project amendments, investment increases, land-use rights applications, compliance inspections, and suspension or termination of approved businesses. Endorsement Application Timeline and Deemed Acceptance In Myanmar, prospective investors seeking approval under the Myanmar Investment Law generally do so through an MIC permit or an MIC endorsement, depending on the nature of the investment. While certain large-scale investment projects require an MIC permit, projects that are not required to obtain an MIC permit may instead apply for an MIC endorsement. Investors seeking MIC endorsement for their planned projects typically submit their applications to the relevant state or regional investment committee. These committees are established under the Myanmar Investment Law and are authorized to approve investments of less than USD 5 million, subject to the project’s nature and location. MIC Notification No. 5/2026 specifies that upon receiving an endorsement application, the relevant investment committee office will check it for completeness and determine whether it can be considered at the state or regional level or must be referred to the MIC; if it must be forwarded to the MIC, this will be done within 10 working days. If an application is within its purview, the committee may reject the endorsement application within 15 working days of receipt; otherwise, the application is deemed accepted. If approved, the endorsement certificate will be issued within 10 working days of the approval decision, subject to applicable procedures. Endorsement Certificate Amendment The notification clarifies which amendments a state

Myanmar’s Directorate of Investment and Company Administration (DICA) has published the guidelines it uses to assess and approve company names for registration in the country. The guidelines, which were published on May 18, 2026, explain how DICA determines whether a proposed name is identical or too similar to an existing name, and they identify words and expressions that may be prohibited or restricted. Businesses planning to incorporate in Myanmar should expect DICA to scrutinize proposed names more closely than it has in the past. Prohibitions on Company Names The Myanmar Companies Law prohibits company names that are identical or similar to existing company names, and DICA’s internal assessment guidelines explain how this rule applies in practice. Under the guidelines, DICA may reject a proposed company name if the proposed name: Is identical or nearly identical to an existing company name; Differs from an existing company name only in punctuation, capitalization, spelling, or transliteration; Only adds words such as “Group,” “Holding,” “International,” “Myanmar,” or “Family” to an existing company name; Merely rearranges the words in an existing company name; Is pronounced similarly to an existing name; Uses the same brand name as an existing company, even if the company carries out different business activities; or Uses an existing brand name together with an abbreviation of that brand name or a shortened form of the name or business description. DICA may also consider whether a proposed name could give the impression that two companies are related, even if they operate in different business sectors. In addition, DICA may review a company name even after registration. If it later determines that the name does not comply with the Myanmar Companies Law or is otherwise unsuitable, DICA may direct the company to change its name under section 26 of the Myanmar Companies Law.

On July 6, 2026, Myanmar’s Ministry of Finance and Revenue introduced revised procedures governing the importation and exportation of goods and vehicles, replacing the framework that had been in place since 2017. The revised procedures were introduced in Notification No. 115/2026, which establishes updated compliance requirements and penalties for importers and exporters, covering licensing, declarations, product specifications, prior arrival of goods, and imports or exports made without the required licenses or permits. Scope Unlike its predecessor (Notification No. 6/2017), which focused primarily on import-related noncompliance, the new notification regulates both import and export activities and introduces a separate penalty schedule for export violations. Exporters are now required to ensure that their exports comply with the approvals stated in export licenses and permits, match the information declared in export declarations, and are supported by the required licenses, permits, and accompanying documents. Import Compliance and Penalties The new notification imposes several compliance requirements on importers. Importers must ensure that the country of origin, branding, labeling, and other product information are consistent with the relevant import license or permit, import declaration, and the imported goods. For vehicles and machinery, the model year must match the year approved by the Ministry of Commerce. Importers must also ensure that goods are not imported before the issuance or after the expiry of the import license or permit, and that the imported quantity does not exceed the approved amount. Failure to comply with these requirements may result in regulatory action. As for the notification’s revised penalties for noncompliance with import licensing requirements, imports made without the required import license, permit, or import declaration may be subject to fines ranging from one to three times the assessable value (AV) of the goods, depending on the category of goods involved. Certain vehicles and machinery, as well as specific
