The compliance of packaging for exporting dangerous goods plays a vital role in ensuring life and property safety. Dangerous goods—including but not limited to explosives, flammables, toxics, infectious substances, corrosives, and radioactive materials—have special and strict requirements for packaging, stowage, segregation, handling, management, transport conditions, and emergency measures. This article, based on a 2022 case where H Customs identified non-compliant packaging for Company As exported dangerous goods, reviews relevant legal regulations and corporate responsibilities to enhance companies regulatory awareness and accountability.

On July 26, 2022, during the inspection of export dangerous goods packaging usage certification, H Customs discovered that the PI numbers (production batch numbers) marked on the packaging containers of two batches of dangerous goods declared by Company A did not match the marks on the sample sheets of the Inspection Results of Performance of Packaging for Entry-Exit Goods provided. Additionally, the height of the UN mark letters and numbers on the open-head steel drums for these two batches was only 3mm, which clearly did not comply with the regulations for marking height on containers with a capacity of 30L or weight of 30kg or less for export dangerous goods packaging. H Customs determined that the packaging usage certification for these two batches of dangerous goods was unqualified and prohibited their export.
