When talking about ATPs (“Adaptation to Technical Progress”), we mainly refer to the updates to the harmonized list of classifications and labelling of substances in CLP from Annex VI. This CLP rule is “alive” and ATPs are additions to the basic rule.

Let us now look at what the individual terms in the above statement mean.

Annex VI to CLP contains a list of harmonized classifications and labels for approximately 7000 hazardous substances. Suppliers of relevant substances or mixtures should use harmonized classification and labelling to prepare labels and Safety Data Sheets (SDSs).

We now know what Annex VI is. But what is CLP?

CLP (Regulation (EC) No 1272/2008), on the other hand, means the framework act, with the abbreviation CLP (“The Classification, Labelling and Packaging”) meaning the Regulation on Classification, Labelling and Packaging of Substances and Mixtures (CLP)). It is based on the United Nations Globally Harmonized System (GHS) and aims to ensure a high level of protection of health and the environment, and the free movement of substances, mixtures and articles.

(You can read more about the CLP Regulation on the ECHA website here).

CLP, on the other hand, is also closely linked to SDSs governed by Regulation (EC) No 1907/2006 (REACH Regulation) and sets out the requirements for the packaging of chemicals.

Knowledge of these basic concepts is essential for understanding the content of regulations and consequently the obligations that these regulations “bring”.
