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 of £12.49 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.

your enquiries.
