Medicinal Claims under the PMD Act

Overview

Medicinal claims are expressions that suggest treatment, prevention or improvement of disease, or an effect on the structure or function of the human body. Even if a product is sold as food, a health food, supplement, cosmetic, beauty product or general consumer good, its labeling or advertising may create PMD Act issues if it makes medicinal or pharmaceutical-style claims.

For import practice, the issue is not limited to the ingredients or physical nature of the cargo. Product labels, manuals, EC pages, advertisements, social media posts, sales materials, testimonials and translated descriptions should also be checked. A product sold overseas as a general product may face regulatory issues in Japan because of how it is marketed to Japanese consumers.

Why Medicinal Claims Matter

Under the PMD Act, products that have not been approved, licensed or otherwise handled as pharmaceuticals or medical products may face problems if they are advertised with pharmaceutical-style efficacy claims. This issue is especially common with health foods, supplements, cosmetics, beauty goods and wellness products.

In Japanese regulatory practice, whether a product is treated as a pharmaceutical product may be assessed based on its ingredients or inherent nature, physical form and the claims or expressions used in labeling, advertising and sales. Even if the ingredients and form appear to be those of an ordinary food or cosmetic, claims may still bring the product within pharmaceutical regulatory scope.

Whether a claim is medicinal is not judged only by one word. The overall impression of the advertisement may matter, including product names, slogans, images, charts, before-and-after photos, testimonials, expert comments, research references and the structure of the sales page.

Products Where This Issue Often Arises

Medicinal claim issues may arise in many product categories, especially where the product is connected with health, beauty, wellness, measurement or body function.

• Health foods and dietary supplements
• Beauty products and cosmetics
• General consumer goods with health-related marketing
• Wellness devices and health equipment
• Testing kits, measuring products and self-check products
• Foods promoted with functional or disease-related wording
• Products sold through EC platforms, social media or influencer marketing

Main Points to Check

• Does the product description refer to a disease name or symptom?
• Does it claim to treat, cure, improve or prevent disease?
• Does it claim an effect on blood pressure, blood sugar, cholesterol, immunity, inflammation, pain, allergies or infection?
• Does it suggest an effect on the structure or function of the human body?
• Do testimonials, reviews or images imply disease improvement?
• Are doctors, experts, research data or clinical-style expressions used to imply therapeutic effects?
• Has overseas marketing copy been translated directly for Japan?
• Has the importer checked Japanese advertising rules before sale?

Personal Import and Business Import

Personal import and business import should be distinguished. A product brought into Japan for an individual’s own use is different from a product imported for sale, resale, EC distribution, advertising, influencer promotion or business use.

However, personal import does not automatically solve all issues. If the product is later sold, advertised, distributed or promoted in Japan, the Japanese labeling and advertising may become a PMD Act issue. For business import, advertising and sales expressions should be reviewed before shipment or before the product page is published.

Common Problems

• An overseas supplement description includes disease names and is translated directly into Japanese.
• A beauty product claims improvement of skin disease or inflammation.
• A health food emphasizes effects on blood pressure, blood sugar, immunity or cholesterol.
• A general wellness product claims treatment or prevention effects.
• Testimonials or before-and-after images strongly suggest disease improvement.
• Research data or expert comments are used in a way that implies therapeutic effects.
• The invoice and HS code show a food or cosmetic product, but the sales page creates pharmaceutical-style claims.

Practical Notes for Shipments to Japan

For shipments to Japan, overseas suppliers and origin-side forwarders should not assume that customs clearance alone means the product can be freely sold with the same claims used overseas. The Japanese importer should check the product category, ingredients, intended use, labeling and advertising together.

This is especially important for health foods, supplements, cosmetics, beauty goods and wellness products. A product may be physically importable, but the way it is sold in Japan may create a PMD Act problem.

Direct translation of overseas marketing copy is a common source of trouble. Expressions that are normal in another country may be too close to medicinal or pharmaceutical claims in Japan.

Relationship with Logistics and Customs

Forwarders and customs brokers are not expected to make final PMD Act advertising judgments. However, they should notice warning signs when cargo is described as a health food, supplement, beauty product, wellness device, testing product or health-related consumer good.

For logistics practice, this is partly a document-control issue. The invoice, packing list, product label, manual, brochure and EC page should not create conflicting impressions. If shipping documents describe the product as a general good but sales materials suggest treatment or prevention of disease, the importer should be asked to confirm the regulatory position.

The issue may arise after customs clearance, especially when the product is listed on an EC site or promoted through advertisements, social media or sales pages. Origin-side logistics teams should therefore understand that Japanese regulatory review may cover marketing materials as well as the cargo itself.

Relationship with Food, Cosmetics and General Goods

Medicinal claim issues often appear at the boundary between food, cosmetics, quasi-drugs, medical devices and pharmaceuticals. A product that is treated as food or cosmetics may still create risk if the claims go beyond the permitted scope for that category.

For example, cosmetic-style claims may be acceptable when they refer to appearance or hygiene within the permitted range, but claims suggesting treatment of disease or improvement of body functions may move the product into a different regulatory issue. Health foods and supplements also require careful wording because food products should not be promoted as if they were medicines.

Where advertising creates a misleading impression about efficacy, the Act against Unjustifiable Premiums and Misleading Representations may also become relevant alongside the PMD Act.

Labeling and Advertising Claims

Medicinal claims are judged not only by product labels but also by the overall advertising impression. Even if direct words are avoided, testimonials, images, graphs, expert recommendations, research references or page design may imply disease treatment or prevention.

Expressions such as “cures,” “works on,” “improves,” “prevents,” “suppresses,” “reduces,” “removes,” or similar wording should be reviewed carefully in context. Before sale in Japan, the importer should check Japanese labels, manuals, EC pages, advertisements and social media content.

Key Takeaway

Medicinal claims are a major PMD Act risk in import and sales practice. Even if the product is imported as food, a supplement, cosmetic or general good, claims relating to disease treatment, prevention, improvement or effects on body functions may create regulatory problems in Japan. Importers and logistics parties should review not only the cargo classification but also Japanese labeling, advertising and sales materials before market launch.
