This column highlights why ISO tank logistics is less about transportation and more about engineering a risk-controlled structure. Liquid cargo reacts to temperature, pressure, and regulations, making pre-shipment design—tank specs, washing standards, documentation, and liability allocation—critical. Most issues occur not in customs but in the post-berthing segment, where terminal rules, congestion, hazardous-cargo limits, and inland-trucking constraints drive hidden costs. B

Black mass import logistics isn’t just shipping a container—it’s bringing in a full set of rules, documents, and responsibilities. The first critical step is confirming whether it is classified as a product or as waste, because unclear classification can trigger approvals, delays, storage costs, and even return/disposal risks. Success depends on contract-level clarity: consistent COA/SDS, defined sampling standards (who/where/how), moisture and impurity controls, secure packa
