CHEMICALS BEFORE BUYING OR USING CHEMICALS, PLEASE READ THE FOLLOWING INFORMATION CAREFULLY UNDERSTANDING THE CLP LABELS The CLP Regulation is the new EC Regulation No 1272/2008 on Classification, Labelling and Packaging of substances and mixtures. The legislation has been introduced throughout the EU as a new system to classify and label chemicals based on the United Nations Globally Harmonized System or GHS. Why is it changing? What are the Signal words? The new system is to allow uniformity within the United The CLP Regulation has introduced two new signal words: Nations so that all countries worldwide have the same ‘Danger’ and ‘Warning’. classification for transporting and supplying chemicals. The If the chemical has a more severe hazard, the label includes GHS provides a single system to identify the hazards that will the signal word ‘Danger,’ in the case of less severe hazards, be the same in every country. the signal word is ‘Warning’. In some instances chemicals may have a signal word but no pictogram. As was the case When is it changing? under the old system there are also a number of substances which carry no hazard warning pictograms or signal words. The CLP Regulation came into force on 20th January 2009, however a transitional period was put into place so that What do these changes mean? industry and users could adapt. Newly purchased substances must be classified, labelled and packaged according to CLP As the criteria for classifying chemicals have changed, some on 1st December 2010, however, those chemicals already on chemicals you have previously used may have changed the shelves can continue to be supplied under old legislation classification, and some that were not previously classified as until 1st December 2012.

CHEMICALS AC-AD CARRIAGE SURCHARGE: Certain chemicals e.g. lithium, potassium, methanol, bromine etc, may now only be transported by ADR vocationally trained drivers. This has forced us to implement a carriage surcharge (subject to application) per order which contains these chemicals (which are clearly marked in the chemical section). Please note: The regulations governing the transportation of chemicals have also been subject to recent changes. The list of chemicals with special carriage requirements has expanded as a result of the ADR 2011 regulations (Carriage of dangerous goods European Agreement concerning the International Carriage of Dangerous Goods by Road). Those chemicals which carry ADR restrictions are indicated within the ‘Chemicals’ section, which follows, by a SUBJECT TO SURCHARGE statement and, as in previous years, are subject to an additional carriage cost. SUBJECT TO SURCHARGE Certain chemicals are of a hazardous nature and require special delivery and handling, which can be expensive or cause delays with the delivery. For this reason we separate chemical requirements from all enquiries and provide a separate quotation for hazardous chemicals.
