Quality disputes can be devastating. NSM ensures that samples are taken according to international standards (ASTM/IP/ISO) to ensure they are truly representative of the entire parcel
In maritime commerce, the quality of the cargo is as important as the quantity. Dry and Liquid Cargo Sampling is a specialized service designed to protect the interests of buyers, sellers, and shipowners by creating a definitive "chain of custody." Whether the cargo is a liquid chemical, petroleum product, or dry bulk commodity, the sampling process ensures that any contamination or quality issues can be traced back to their source. At NSM, we act as the independent witness, ensuring that samples are truly representative of the entire shipment and not just a single "clean" section.
The sampling process for liquid cargo is particularly technical, requiring strict adherence to ISO or ASTM standards. Our surveyors extract samples from various levels within the barge or shore tanks before loading, and again from the vessel’s tanks after transfer. We use "all-level" or "spot" sampling techniques to ensure that any settling of impurities or water is detected. For dry cargo, we monitor the conveyor belts or the cargo holds, taking representative increments throughout the loading process. This prevents "slugs" of contaminated material from being hidden within a larger shipment.
Once samples are collected, they are immediately sealed with tamper-evident tags and logged into a formal sampling report. These samples are often split: one set is sent to a laboratory, one is kept on board, and another is retained by NSM for future reference. This "witnessed" sampling is the most powerful defense a shipowner has against quality claims. If a receiver alleges contamination, the sealed "load-port" samples provide the physical evidence required to prove the condition of the goods at the time of shipment, potentially saving millions of dollars in legal fees.
NSM provides a standardized approach to quality protection, ensuring that every sample collected is defensible in a court of law. Our protocols focus on the following core areas:
