In April 2021, Tanzania’s Bureau of Standards (TBS) announced draft standards that propose limits for heavy metals and total aromatic amines in food contact materials (FCMs). Additionally, it also announced to the World Trade Organization (WTO) a positive list for colorants and dyes allowed for use in FCMs. Both standards are set to be adopted by July 2021 and become effective in January 2022.
The relevant heavy metals and their proposed limits by packaging mass include:
- barium – 0.01%;
- lead – 0.01%;
- arsenic – 0.05%;
- mercury – 0.05%;
- cadmium – 0.1%;
- zinc – 0.2%;
- selenium – 0.01%;
- chromium – 0.025%;
