International WHO Code

The International Code of Marketing of Breastmilk Substitutes from the World Health Organization (the Code) covers marketing and promotion of products meant to substitute for breastfeeding. It does not ban their sale or use; it simply restricts how they may be promoted and marketed in order to protect the health of infants and young children by supporting breastfeeding/nursing.

LLLI fully supports the International Code of Marketing of Breastmilk Substitutes and subsequent World Health Assembly resolutions.

We review our partnerships and relationships regularly to ensure that we have cooperative relationships only with those who meet their obligations under the International Code.

Why do we need a Code?

The Code is needed to support infant health and prevent unscrupulous practices which may undermine breastfeeding/nursing in the production, promotion, and sale of breastmilk substitutes.

What is the Code in law?

The Code is a World Health Assembly Resolution:; a recommendation that nations pass legislation to implement the guidance in the Code so that it is enforceable.However, there is no legal penalty if a nation does not implement a resolution that they adopted. As a result, except in a very few countries that have included some parts of the Code in legislation, there is no way to penalize any manufacturer or distributor of formula or other products covered under the Code if they fail to meet their obligations under the Code.

An updated version of the Code has been issued which discusses the rules governing the marketing of breast milk substitutes.
Every other year, the World Health Assembly (WHA) reviews changes in the industry, such as communications and other technological advances allowing new means of reaching families for advertising. The WHA discusses any changes in the marketing of breastmilk substitutes that may need to be addressed for the protection of the health and development of infants and young children. Their conclusions are expressed in additional WHA resolutions that are to be read as part of the Code.
