What Does Marine Insurance Cover: A Complete Guide for Businesses and Traders

Introduction

Whether you’re shipping bulk commodities across oceans or transporting goods through inland waterways, risks are part of every journey. Storms, piracy, accidents, and even mishandling can cause substantial financial loss. That’s why businesses turn to marine insurance. Understanding what marine insurance covers helps you select the right policy and safeguard your cargo and investment.

According to the International Union of Marine Insurance (IUMI), the global marine insurance market is valued at over $31 billion annually (IUMI), highlighting its critical role in protecting global trade.

Marine Insurance: The Basics

Marine insurance provides coverage for goods, vessels, and related liabilities during transit over water and sometimes land or air in multimodal transport. It is not limited to ocean voyages—it can also include inland water transport and connecting journeys.

Two primary categories:

• Hull Insurance – Protects ships, boats, and other vessels.
  
  

• Cargo Insurance – Covers goods in transit against physical loss or damage.

Risks Not Covered by Marine Insurance

While marine insurance offers wide protection, some risks are excluded unless separately insured:

• War and political unrest (covered under war-risk insurance)
  
  

• Delay-related losses (unless caused by insured damage)
  
  

• Poor packaging by the shipper
  
  

• Inherent vice (damage due to the nature of goods, like natural decay)

Understanding exactly what marine insurance covers ensures:

1. You buy a policy that matches your shipping risks.
