Hong Kong is often the simplest entry point in the region for a Japan-made supplement — most food supplements can be sold without pre-market government approval. That simplicity has a trade-off: because there is no registration checkpoint reviewing the label and claims before sale, the burden falls entirely on the label and advertising being correct from day one, and on staying clearly on the food side of a boundary with Chinese medicine.
This guide covers who regulates supplements in Hong Kong, why most need no pre-market registration, when a product instead falls under Chinese medicine rules, and what your label and advertising must and must not say.

Who regulates supplements, and the general rule on registration
The Centre for Food Safety, part of Hong Kong’s Food and Environmental Hygiene Department, oversees food supplements as food, and — unlike a pharmaceutical product — most need no pre-market evaluation or registration before sale.
Health supplements in Hong Kong are generally treated as food and regulated under the Public Health and Municipal Services Ordinance (Cap. 132) rather than as a drug. There is no general licensing or registration scheme that a food supplement must pass through before it reaches the shelf; the responsibility instead sits with the seller to make sure the product is safe, correctly labelled and only makes claims the law allows. The Centre for Food Safety enforces compliance after the fact — through inspection, sampling and label review — rather than approving the product beforehand.
| Route | Pre-market approval | Ongoing responsibility |
|---|---|---|
| Ordinary food supplement | None required | Seller/importer ensures safety, correct labelling and lawful claims; Centre for Food Safety enforces after sale |
| Pharmaceutical product | Registration with the Pharmacy and Poisons Board required | Cannot be sold as a food supplement at all |
| Proprietary Chinese medicine | Registration with the Chinese Medicine Council required | Applies only where the product falls into this category — see below |
The boundary with Chinese medicine
A product crosses from “food” into “proprietary Chinese medicine” — and needs separate registration — mainly through the claim it makes, not simply through containing a Chinese-medicine-style ingredient.
Hong Kong’s Chinese Medicine Ordinance covers products presented for use in the prevention, diagnosis or treatment of disease, or products whose ingredients and claims are drawn from recognised traditional Chinese medicine texts. A product built around an ingredient also used in traditional Chinese medicine, but sold with only general health-maintenance or nutritional wording, can generally stay on the food side of the line and follow the ordinary supplement route. The same ingredient, sold with a disease-related or therapeutic claim, moves the product into proprietary Chinese medicine, which requires registration with Hong Kong’s Chinese Medicine Council before sale — a separate and much heavier process than the food route.
This distinction matters most for a Japan-made product built around a botanical or fermented ingredient with a long history in both Japanese and Chinese traditional use. The ingredient itself does not decide the category; the claim on your label and in your marketing does.

Label language and content
A Hong Kong food label may be written in English or in Chinese, but once you use both languages on the same label, certain elements — the food name and ingredient list — must appear in both.
Hong Kong’s Food and Drugs (Composition and Labelling) Regulations set out what a prepackaged food label must show: product name, ingredient list, net quantity, a date marking, and the name and address of the manufacturer or the local principal in Hong Kong, among other items required by the regulation’s schedules. A single-language label — entirely in English or entirely in Chinese — is acceptable; the bilingual requirement only applies once a label mixes both languages, in which case the name of the food and the ingredient list must be shown in both.
| Element | Rule |
|---|---|
| Language | English alone, Chinese alone, or both — if both are used, the food name and ingredient list must appear in both languages |
| Core content | Product name, ingredient list, net quantity, date marking, manufacturer/local responsible party |
| Nutrition information | Governed by Hong Kong’s Nutrition Labelling Scheme for prepackaged food, alongside the general labelling rules |
Advertising and claim restrictions
Hong Kong’s Undesirable Medical Advertisements Ordinance restricts what any food, including a supplement, may claim about a specified list of diseases and conditions, regardless of how the pre-market side is regulated.
The ordinance restricts advertisements — including labels and packaging, not just paid media — that claim a product can treat, cure or prevent a schedule of specified diseases, and separately restricts certain claims for orally consumed products more broadly. Because Hong Kong has no pre-market label review for ordinary food supplements, this ordinance is where an overreaching claim is most likely to create a legal problem after the product is already on sale, so it deserves the same care as the ingredient-safety check itself.
Documents a Japanese factory can provide
A specification sheet, a Certificate of Analysis and a Certificate of Free Sale support a Hong Kong importer’s own due diligence, even though none of them is filed with a Hong Kong authority before sale.
- Specification sheet. Full ingredient list, amount per serving, dosage form and packaging detail.
- Certificate of Analysis (CoA). Batch-specific test results confirming the product matches specification.
- Certificate of Free Sale. Confirms the product is legally sold as a food in Japan; useful to a Hong Kong distributor or retailer conducting its own supplier due diligence, since there is no government registration step to rely on instead.
- Certificate of origin. Supports customs clearance into Hong Kong.
Before you ask for a quotation
- The exact wording of any claim, checked against the food/Chinese-medicine boundary and the Undesirable Medical Advertisements Ordinance
- Whether your label will be English-only, Chinese-only, or bilingual
- Dosage form and any botanical or fermented ingredient with a Chinese-medicine history that needs its claim checked carefully
- Which documents you need from the factory: specification sheet, CoA, Certificate of Free Sale, certificate of origin

Frequently asked questions
1. Does a Japan-made supplement need government approval before it can be sold in Hong Kong?
Usually not. Most food supplements are not subject to pre-market evaluation or registration in Hong Kong; the responsibility for safety, correct labelling and lawful claims sits with the seller, and the Centre for Food Safety enforces compliance after the product is on the market.
2. When does a supplement need to be registered instead of sold as ordinary food?
When it is presented for treating, diagnosing or preventing disease, or its ingredients and claims come from recognised traditional Chinese medicine texts — this moves it into proprietary Chinese medicine, which needs registration with the Chinese Medicine Council, a separate and heavier process than the food route.
3. Can I use an English-only label in Hong Kong?
Yes. A label can be entirely in English or entirely in Chinese. The requirement that the food name and ingredient list appear in both languages only applies once a label uses both.
4. What can go wrong if my supplement label makes a strong health claim in Hong Kong?
Because there is no pre-market label review, an overreaching claim is more likely to surface as a problem after sale, under the Undesirable Medical Advertisements Ordinance, which restricts disease-related and certain other claims for orally consumed products.
5. Does the Japanese factory register anything with Hong Kong authorities?
No. There is generally no pre-market registration step for a food supplement in Hong Kong. The factory instead supports the importer with documents such as the specification sheet, Certificate of Analysis and Certificate of Free Sale for its own due diligence and customs purposes.
