DGR Class 8 — Corrosives

DGR Class 8 — Corrosives is a dangerous goods classification for liquids or solids that cause full thickness destruction of human skin at the site of contact within a specified period of time or, in the case of leakage, will materially damage or destroy other goods or the means of transport. This class is governed by IATA Dangerous Goods Regulations (DGR) guidelines for identifying, documenting, packing, labeling, marking, and handling these materials in air cargo operations. Class 8 dangerous goods are assigned to packing groups I (high danger), II (medium danger), or III (low danger) to indicate the degree of hazard. Common examples include acid battery fluid, sulfuric acid, sodium hydroxide, and wet batteries filled with acid.

A Lufthansa Cargo shipment from Frankfurt (FRA) to Los Angeles (LAX) carries AWB number 020-12345678 containing 50 kg of battery acid classified as UN 2794, BATTERIES, WET, FILLED WITH ACID, requiring Class 8 corrosive labeling and packing instruction 870. An Emirates SkyCargo freight from Dubai (DXB) to New York JFK (JFK) transports AWB 176-87654321 with 25 liters of hydrochloric acid solution classified as Class 8, Packing Group II, requiring appropriate corrosive substance markings and documentation on the Shipper's Declaration for Dangerous Goods.
