Question: Are SVHCs present in glass or ceramic frit exempted from EU REACH regulation?
Answer: Though many substances of very high concern(SVHCs) are precursor substances to the formation of glass, those which still remain in the glass after formation (i.e. becoming an Article) and present above 0.1% w/w must be reported under Article 33 requirements.
For example, the FAQ on REACH from the trade association Glass Alliance Europe provides a composition for lead crystal glass:
- 25% oxygen
- 30% silicon (originating mainly from quartz sand)
- 25% lead
- 10% sodium or potassium
- 10% calcium (originating mainly from limestone)
- 1% other components like Ti, Fe, and F to give specific properties to the glass
The weight of the lead (an SVHC) in the finished glass article must be assessed against the article's weight to determine whether it is above the 0.1% threshold. Since it is present at 25% w/w, which is above 0.1%, the Article 33 reporting requirements apply.
