Billions of dollars of goods and merchandise are shipped around the world each year, resulting in high-risk cargo exposures. These risks can span many industries, including manufacturing, distribution, healthcare, energy, construction and technology. Marine Cargo insurance covers physical loss and/or damage of goods while in transit between the point of origin through the final delivery and is not generally thought of as a solution for property brokers.

Stock Throughput Policies (STP) are designed to safeguard a company's inventory and the flow of goods, from production sources to their final destinations—be it in storage or retail outlets. Comprising three main components—property or stock insurance, ocean cargo insurance and inland transit insurance—STP offers a holistic approach to coverage throughout the supply chain.


Key Benefits of STP

The flexibility of STP allows it to apply to any inventory stored in a warehouse (owned or third-party) and cater to a diverse range of businesses, including:

  • Manufacturing operations
  • Cold storage facilities
  • Retail storage
  • Transit-only
  • Storage-only, including excess layers

STP can be a more affordable way to insure your inventory with end-to-end coverage. Instead of having multiple policies in place for each step of the supply chain process, STP consolidates your coverage – allowing you to work with just one carrier and eliminating potential gaps in coverage. STP also offers:

  • Lower Pricing: STP utilizes average inventory values, resulting in fairer representations of exposures. This approach often leads to lower rates and premium savings for the insured.
  • Lower Deductibles: Inventory in-store typically incurs deductibles ranging from $10,000 to $50,000 while transit deductibles range from $1,000 to $5,000. The absence of percentage deductibles for CAT perils in the CST market contributes to lower deductibles.
  • One Seamless Policy: The integration of property, transit and storage coverage into a single policy eliminates coverage gaps throughout the entire process from start to finish, both on a primary and contingent basis.
  • Wider Coverage: Unlike traditional property coverage that focuses on bricks and mortar, STP extends coverage to various interests stored. It offers all-risk protection against physical loss or damage and includes spoilage coverage for temperature-sensitive goods.
  • Selling Price Basis of Valuation: In the event of a loss, an STP policy can provide a selling price Basis of Valuation (BOV), ensuring the insured is indemnified as if the product had been sold, including any profit margin.
  • CAT Coverage: The STP London market offers full coverage for earthquake, windstorm and flood. In addition, the full policy limit will apply to these perils.



The incorporation of STP into the insurance landscape represents a paradigm shift, offering businesses a seamless, comprehensive and cost-effective solution. As the industry evolves, STP emerges as a valuable tool, providing not just coverage but strategic advantages for businesses engaged in various stages of the supply chain. This innovative approach aligns with our commitment to delivering efficient and tailored insurance solutions.
