Cambodia: Commercial Advertising Sub-Decree Mandates Khmer Language and Establishes Other Restrictions

Cambodia’s new Sub-Decree on the Management of Commercial Advertising of Products and Services, issued November 4, 2022, is a notable step in ensuring that advertisers comply with advertising regulations, advertise ethically and legally, and avoid deceiving or misleading consumers. The sub-decree regulates both traditional advertising (e.g., print, broadcast, display, etc.) and digital forms (e.g., social media, online, mobile, etc.), and also includes provisions that address advertising alongside rewards—a popular method of advertising in Cambodia.

The Ministry of Commerce is the authority tasked with issuing certificates of advertising compliance (more below) and is responsible for monitoring and assessing the compliance of advertisements with this sub-decree and related regulations. The ministry also enforces against unfair advertising through its Consumer Protection, Competition and Fraud Repression Directorate-General (CCF).

Key Issues

The sub-decree addresses a range of key issues relevant to companies advertising products and services in Cambodia.

Licensing

The sub-decree does not appear to set new licensing or permit requirements, but it requires advertisements for products and services to comply with the sub-decree, any existing regulations (unless they contradict the sub-decree), and future regulations. If regulations require a license for advertising, this should be obtained from the relevant authorities. One example is advertising of pharmaceuticals, which requires a license from the Ministry of Health under existing regulations.

Types of Advertisement

Under the sub-decree, advertising is divided into two types: advertisements with rewards and advertisement without rewards. Rewards may include souvenirs, lucky draws, and other rewards attached to the purchase of products and services.

Forms of Advertisement

Forms and means of advertising specified in the sub-regulation include the following:

  • Advertising via audiovisual media such as TV, electronic broadcasting media (including both satellite and cable TV), and so on;
  • Electronic advertising, such as websites, e-mail, electronic messages (in written, voice, or image form), ringtones, social networks, computer applications, and advertisements displayed on a phone or other smart device, or other internet-browsing software;
  • Print advertising such as newspapers, magazines, and bulletins;
  • Advertising via audio broadcasting, including radio broadcasting of any kind;
  • Advertising via equipment for storing any kind of audio and video, including CD, VCD, DVD, DVD, 3D/4D/5D movies, videos, or animations, and other cultural programs;
  • Advertising via stage performances such as concerts, art, and entertainment;
  • Display advertising on LCD screens, billboards, information boards, wallpaper, banners, posters, and other materials;
  • Advertising via discount sales, special discount sales, warehouse clearance sales, and fixed-price sales;
  • Advertising on the packaging of goods;
  • Advertising in a transportation center or on transportation vehicles;
  • Advertising in a meeting, workshop, training session, or press conference;
  • Advertising via public display of product samples;
  • Advertising in educational institutions, sports centers, health institutions, religious institutions, business centers, and entertainment, banking, and industrial establishments; and
  • Advertising in public.

The sub-decree further provides that advertisement text includes any words, content, video, animations, or any other idioms intended to advertise products and services. Notably, the definition specifically refers to “any meaning,” e-mails in text or voice, songs and folk songs, poems, chants, comedy, ringtones, short videos, 3D/4D/5D animation, or other idioms intended to advertise the supply of products and services.

Obligations for Advertisements with Rewards

Under the sub-decree, advertisers that use rewards must do the following:

  • Confirm the total amount of products that come with the reward;
  • Specify the type and amount of each reward and the total amount of rewards;
  • Specify the validity of the reward;
  • Provide clear information on the location for providing or obtaining a reward;
  • Provide documents or information on the identity of winners on a monthly and annual basis (presumably to the authorities).

Certificate of Advertising Compliance

The sub-decree refers to a certificate of advertising compliance, which appears to be voluntary. The sub-decree uses the wording “may apply” when referring to the certificate, but further implementing regulations may clarify this issue. The certificate confirms that the advertisement is in line with Cambodian law.

Under the sub-decree, certificates of advertising compliance can be applied for prior to advertising products or services. The CCF will decide on the application within five working days of receiving the application. The validity of the certificate of advertising compliance may be based on the length of the advertisement, but it will not exceed one year. A certificate of advertising compliance may be renewed 30 days before its expiration date.

Language Requirement

Advertisement of products and services must be in Khmer language, except for (1) trademarks or tradenames that are in a foreign language and cannot be replaced by Khmer language, (2) books, websites, and products published in print that have been approved for publishing in Khmer and English, and (3) radio and television broadcasting in Khmer and foreign languages.

For advertising that includes both Khmer script and that of English (or another language), the Khmer script must be twice the size of the foreign script and should always be placed above the foreign script.

This is a major new requirement, as it requires advertisements to use Khmer language predominantly. This would mean a major shift in the advertising landscape. Advertisers should pay attention closely to see how this new language requirement functions and how broad its scope is. This will be of interest to many, such as streaming services that advertise their content predominantly in English in Cambodia.

Prohibited Content

The following actions are prohibited in advertising:

  • Revealing state secrets, endangering national independence, national defense, national security, the economy, international relations, or social security and order;
  • Adversely affecting the country’s honor or national dignity, the national flag, a national symbol, the national anthem, religious institutions, the monarchy, national and international organizations, national heroes, leaders, and the country’s or any individual’s reputation;
  • Adversely affecting historical values, ethics, culture, customs, national traditions, beliefs, and religion.
  • Expressing racism or discrimination based on color, sex, language, beliefs, religion, political tendencies, national origin, social status, resources, or disability;
  • Encouraging children to think, act, speak, or behave contrary to custom, tradition, and morality, adversely affecting their health, safety, or natural development;
  • Forcing other people to advertise against their will;
  • Hiring someone to lie about receiving a reward or benefit from goods and services;
  • Using someone else’s content and text without their permission;
  • Comparing goods and services with the intention of degrading or affecting the products and services of other individuals;
  • Using words such as “best”, “number one”, “superior”, “unparalleled” or words with similar meanings without documents supporting this, and confirmed by relevant authorities;
  • Adversely affecting users’ health and safety;
  • Violating other relevant provisions in force.
  • Advertising products and services that are prohibited by other relevant authorities and affect public safety, traffic safety, and social order.

Additionally, advertisements must not be deceitful, deceptive, or misleading, regardless of the type, form, and means of the advertisement.

Penalties

Individuals who advertise products and services in violation of the provisions of the sub-decree are subject to the following penalties:

  • Written warnings;
  • Suspension, revocation, or cancellation of advertising license or certificate of compliance of advertising; and
  • Suspension, revocation, or cancellation of business registration certificate, license, or business license for service business.

Relevant ministries, institutions, and authorities may take further action against such violations such as halting, removing, and confiscating advertisements.

Conclusion

The sub-decree provides advertisers of goods and services relatively clear guidelines and rules, which is helpful to foster a clear and level playing field among businesses.

With the sub-decree setting out a clear enforcement role for the CCF, we expect active enforcement to start taking place soon, as this authority has been given a substantial budget to raise the bar for consumer protection in Cambodia. We have already seen the CCF actively addressing certain advertisements that promise rewards with their products. The CCF has issued notices highlighting issues, inviting companies to explain their rewards programs, and providing the companies guidance on how to implement a compliant rewards program. Recently, a stern cautionary notice went out from the CCF, warning of enforcement action against companies implementing a noncompliant rewards program.

However, the new sub-decree also raises new concerns and leaves uncertainties, including on its scope of application and how existing laws and regulations tie into the sub-decree. The Khmer language requirement will be an onerous obligation for some businesses, and pushback can be expected. However, we note that most consumer protection-related laws and regulations that have been adopted in the last few years require a shift to Khmer language. We note that labeling laws, consumer information regulations, and now advertisement rules require Khmer language, which is a sensible step to protecting Cambodian consumers and ensuring they can make well-informed decisions when purchasing products and services in Cambodia.

A new decree in Vietnam brings significant implementation clarity to the country’s existing extended producer responsibility (EPR) legal framework. An EPR mechanism was first codified in Vietnam in the 2020 Law on Environmental Protection amid ongoing challenges surrounding the collection and treatment of product and packaging waste. The mechanism was progressively detailed through Decree No. 08/2022/ND‑CP and its successive amendments, but the regulatory framework remained insufficiently developed, notably in terms of support mechanisms for waste collection, recycling, and treatment. The newly launched regulations in Decree No. 110/2026/ND-CP (Decree 110), issued on April 1, 2026, and taking effect on May 25, 2026, stipulate fully and clearly the responsibility of manufacturers and importers to recycle products and packaging and to treat waste. Some key provisions of Decree 110 for manufacturers, importers, and related stakeholders are presented below. Subjects of EPR The Law on Environmental Protection assigns responsibility to manufacturers and importers for product and packaging recycling (under Article 54) or waste collection and treatment (under Article 55), depending on the type of products and packaging they produce or import. Decree 110 elaborates on these EPR provisions by specifying the responsible entities and listing out the types of products and packaging subject to recycling and waste treatment responsibilities. Decree 110 clarifies the responsible entities in special cases, such as when products under the same brand are made by multiple manufacturers, when there is a contract manufacturing or entrusted import relationship, and when the manufacturer or importer is part of a corporate group. Notably, exemptions may be applied in some scenarios, such as for manufacturers and importers of products and packaging exclusively for export, temporary import and re-export, or research and testing purposes, as well as for entities with annual revenue from related products not exceeding VND 30 billion.

As digital commerce continues to reshape consumer behavior in Thailand, the Office of the Consumer Protection Board (OCPB) has been taking steps to review and update key regulations for online platforms. The OCPB has had a particular focus on addressing the risks posed by e-marketplace businesses—from misleading product information to fraudulent online transactions. Some of the regulator’s current legislative efforts related to Thailand’s labeling regulations as well as potential changes to the country’s law on direct sales and marketing. Proposed Changes to Consumer Protection Labeling Regulations On February 24, 2026, the OCPB convened a public hearing to review the Notification of the Committee on Labels re: Specification of Goods as Controlled Label Goods B.E. 2565 (2022) and its annex issued under the Consumer Protection Act. The closed-door session, which started the OPCD’s process of seeking feedback on the proposed changes, brought together representatives from government agencies, business operators, and consumer groups. The OCPB explained that its review of the labeling regulations aims to address regulatory gaps arising from evolving commercial practices, particularly the expansion of e-commerce and cross-border transactions. Authorities highlighted recurring issues involving product information that is unclear, incomplete, or potentially misleading in digital sales channels. The proposed revisions are intended to improve consumers’ access to accurate and complete product information, ensure that label disclosures remain relevant amid the growth of e-commerce, and strengthen protections against deceptive or misleading digital advertising. The review is being undertaken pursuant to the Consumer Protection Act B.E. 2522 (1979). As part of the initiative, the OCPB signaled a potential update to the categories of “controlled label products” as well as enhanced disclosure obligations for business operators, with the broader aim of promoting greater transparency, reinforcing operator accountability, and aligning Thailand’s labeling framework with current market conditions. The OCPB secretary general emphasized that

On March 30, 2026, Thailand’s Customs Department announced a strategy to raise import duties on a broad range of consumer goods—including plastic items and electronics accessories—to their maximum statutory ceilings, which often sit at 30% or 40%. Many of these goods currently benefit from promotional or incentive rates as low as 5%. For importers, e-commerce platforms, and logistics providers, this development demands immediate attention. While these increases generally require cabinet approval, they do not require full parliamentary amendment of the Customs Tariff Decree B.E. 2530, as the Customs director-general and the finance minister hold delegated authority to adjust rates within existing statutory bounds. Businesses should not assume that the legislative process will provide significant lead time before higher rates take effect. Death of the De Minimis: Abolishing the THB 1,500 Loophole This “ceiling-rate” policy, which is designed to equalize the landed cost of foreign goods with the domestic production costs of Thai manufacturers, builds on a sweeping set of customs reforms that have already begun to reshape Thailand’s trade environment. The foundation of this new regime was laid on January 1, 2026, when Thailand formally abolished the longstanding THB 1,500 duty exemption for small imported parcels under Customs Notification No. 219/2568. Every imported item is now subject to VAT and applicable import duties for its declared value, regardless of parcel size or transaction amount. By narrowing the scope of exemptions previously granted to low-value goods under the Customs Tariff Decree B.E. 2530, the government has made clear that the era of tax-free cross-border micro-imports is over. Three-Phased Strategy and Legal Modernization The March 30 announcement is the second phase of a three-part regulatory roadmap: Immediate enforcement: The removal of the THB 1,500 loophole and the imposition of VAT on all parcels, effective January 1, 2026.

Thailand’s Office of the Consumer Protection Board has opened a public hearing period on draft regulations governing the transfer of direct sales and direct marketing businesses. The draft Notification of the Direct Sales and Direct Marketing Committee: Criteria and Procedures for Business Transfer and Amendment of Registration for Direct Sales or Direct Marketing Businesses establishes a compliance-focused process with strict documentation requirements and timelines for transferring direct sales and direct marketing businesses. The proposed framework also defines the roles of transferors and transferees and establishes application procedures with the Office of the Consumer Protection Board. Applications may be submitted in person or electronically and will be examined to confirm they are complete, authentic, and compliant with legal requirements. This includes verification that: The transferee meets all required qualifications; No disqualifying factors apply; and The applicant is not subject to legal restrictions. The public hearing period is open until April 29, 2026. Direct sales and direct marketing business operators should prepare for these proposed requirements to ensure compliant implementation once the regulations are finalized.
