TCO Development will remove five polymer flame retardants from the TCO Certified Accepted Substance List. The validity of these assessments has now expired and no new updated assessment reports have been submitted.
Each certifying brand owner has been contacted about this matter and given time to investigate their use in certified products with their suppliers. The result is that the five flame retardants will be removed on July 1, 2019. Products certified before this date are permitted to reach the end of the certificate validity even if the product includes any of these five flame retardants. Any new application using any of these or other substances not on the TCO Certified Accepted Substance List must submit a GreenScreen® assessment report with an approved benchmark, in accordance to TCO Certified generation 8 criterion 7.3 and 7.4.
Please contact Stephen Fuller, Criteria Development & Compliance Manager at TCO Development if you have any questions.
