Hong Kong Implements Ban on Partially Hydrogenated Oils and Introduces Mandatory Labeling for Fully Hydrogenated Oils

In a proactive move to safeguard public health, Hong Kong, China, is set to enforce stringent regulations beginning December 1, 2023. The city will officially prohibit the use of partially hydrogenated oils in food and, concurrently, require the mandatory labeling of fully hydrogenated oils. This dual approach aims to eliminate industrially produced trans fatty acids, known to pose health risks, from the local food supply.

Partially hydrogenated oils, commonly found in margarine, cocoa butter substitutes, and non-dairy fats, have been identified as a significant source of trans fatty acids, detrimental to heart health. In alignment with global trends, countries like the United States, Canada, Thailand, and Singapore have already banned the use of partially hydrogenated oils, with Australia and New Zealand planning similar measures for processed foods.

The recent regulatory changes in Hong Kong, as outlined in the "2021 Hazardous Substances in Food Quality (Amendment) Regulations" and the "Food and Drugs (Composition and Labeling) (Amendment) Regulation 2021," categorize partially hydrogenated oils as prohibited substances in food. Simultaneously, pre-packaged foods containing hydrogenated oils, specifically fully hydrogenated oils, are mandated to carry detailed labeling.

Key Regulations:

1. Prohibition of Partially Hydrogenated Oil Usage:

- As of December 1, 2023, the import, sale, or delivery of foods containing partially hydrogenated oils for human consumption will be strictly prohibited.

- This ban encompasses all food types, including prepackaged and non-prepackaged items, as well as edible fats, oils, and food additives.

*Note: Foods exceeding 2% trans fatty acid content in total fat may undergo further investigation by the Center for Food Safety to determine potential partially hydrogenated oil content.*

2. Mandatory Labeling of Fully Hydrogenated Oil:

- The Food and Drugs (Composition and Labeling) (Amendment) Regulation 2021 mandates that if a food consists of or contains hydrogenated oil, the ingredient list must reference "hydrogenated oil" or modify the oil name with the term "hydrogenated."

- Examples of acceptable labels include "hydrogenated," "hydrogenated oil," "hydrogenated fat," "fully hydrogenated oil," and other variations.

*Note: The removal of hydrogenated oil from the list of exempted ingredients emphasizes the need for accurate labeling.*

In summary, these regulations underscore Hong Kong's commitment to promoting healthier dietary choices and enhancing food safety. The Center for Food Safety will conduct rigorous food surveillance, including testing at import, wholesale, and retail levels, to assess risks associated with partially hydrogenated oils and trans fats. Stringent enforcement actions will be taken against any illegal foods found in violation of these regulations.

Export companies are advised to adjust ingredient choices, opt for alternatives devoid of partially hydrogenated oils, and request relevant documentation from suppliers to ensure compliance. In cases where fully hydrogenated oils are used, strict adherence to labeling requirements is essential. The comprehensive approach adopted by Hong Kong aligns with international efforts to create a healthier and more transparent food industry.
