Danger or no danger, it is a matter of international law that packaged goods destined for foreign ports have to be handled with the utmost care. The idea is to provide protection not only for the people in these foreign cities but protection for the packaged goods as well. Port authorities and for that matter, border patrol officers, are still taking a vigilant line on any goods crossing state lines or national borders that might be dangerous.
This needs to be explained. And you could also ask the question in the meantime. Just what would constitute dangerous goods? How could you categorize them? Are the imminent dangers intentional or is this the nature of the goods? And when dangerous goods packaging is done, how different will it be from the packaging of other goods not hazardous to the public? Port authorities and all other stakeholders will have provided all concerned parties with a functional checklist of what would constitute dangerous goods or materials that need to be transported over long distances, usually to different countries around the world but also across the state lines.
They will also be providing commercial customers with clear guidelines on how these goods need to be handled once they leave port. And in other areas, legal instructions will have been given to processing centers and manufacturers on how their dangerous goods need to be packaged prior to distribution and transportation. Laws have been made in this regard. Apart from confiscating the goods or placing them under quarantine for indefinite periods of time, offending parties are known to receive stiff penalties and even jail terms.
This is a serious matter and there is no beating about the bush. It is in your own best interests to abide by the laid-down laws.
