Which chemical products require ADR transport
Chemistry is the sector with the widest variety of dangerous classes in circulation. The recurring families:
- Flammable solvents — toluene, xylene, methyl ethyl ketone (MEK), acetone, alcohols, esters (class 3)
- Mineral acids — hydrochloric, sulfuric, nitric, phosphoric (class 8)
- Strong bases — sodium hydroxide, potassium hydroxide in solution (class 8)
- Organic peroxides — benzoyl peroxide, concentrated hydrogen peroxide (class 5.2, special regime with temperature control)
- Hypochlorites and oxidizers — sodium hypochlorite in solution, chlorates (class 5.1)
- Toxic substances — cyanides, isocyanates, certain synthesis intermediates (class 6.1)
Each family has different operational restrictions: organic peroxides require active temperature control, hypochlorites release chlorine if contaminated, acids and bases can never share the bay.
Italian chemical clusters
Industrial geography concentrates demand in specific points:
- Marghera and Mantova — base chemistry, plastics, intermediates
- Ravenna — fertilizers, rubber, specialties (Versalis, Yara)
- Ferrara — polyethylene, polypropylene, pharma-chemical specialties
- Brindisi-Taranto — integrated petrochemicals
- Lacchiarella and lower Lombardy — secondary chemistry, additives, formulations
- Bormida valley — historical chemistry of lower Piedmont
- Settimo Torinese — industrial paints, intermediates
To these add the dense network of formulators, industrial detergent producers and chemical labs in the Milan-Bergamo-Brescia triangle.
Regulatory and operational specifics
Beyond ADR, the chemical sector is regulated by CLP (labeling and classification), REACH (registration of substances above one tonne per year), Seveso III for major-accident-hazard sites. The extended Safety Data Sheet (eSDS) is mandatory for any dangerous substance placed on the European market and is the operational reference document for the carrier.
On the logistics side, route restrictions are significant: some Alpine tunnels have specific ADR categories, night transit is forbidden for certain substances, cities enforce time windows. Route planning is part of the service, not an extra.
