HS Code 89.04 – Tugs and pusher craft

HS code 8904 is a 4-digit heading in the Harmonized System that covers: Tugs and pusher craft. Heading 8904 of the Harmonized System encompasses 'Tugs and pusher craft,' playing a pivotal role in international maritime logistics and port operations. This classification specifically covers vessels whose primary function is to provide propulsion assistance to other vessels or floating structures, rather than carrying cargo or passengers themselves. The scope includes a diverse range of tugboats, such as harbor tugs for maneuvering large ships in confined spaces, powerful ocean-going tugs for long-distance towing, specialized salvage tugs for emergency recovery operations, and escort tugs designed for safety in hazardous waters. Additionally, it covers pusher craft, which are commonly used on inland waterways to propel barges by pushing them. The key boundary is the primary design purpose; if a vessel has towing capabilities but is primarily for transport, it would fall under other headings like 8901. Accurate classification under 8904 is crucial for trade compliance, affecting applicable duty rates, import/export regulations, and adherence to specific maritime safety standards. Historically, tugs have been indispensable since the advent of steam power, revolutionizing port efficiency and enabling global trade by assisting larger, less maneuverable vessels. Their continued evolution supports complex offshore energy projects and modern shipping. Within Chapter 89, which covers 'Ships, boats and floating structures,' 8904 carves out a distinct niche for vessels defined by their functional support role, highlighting the specificity required in customs classification.

Commonly confused with vessels of heading 8901 (cruise ships, ferries, cargo vessels) if the tug has limited cargo or passenger capacity, or 8905 (dredgers, floating cranes) if the tug is modified for ancillary functions. The key distinction is the *primary function*. A tug's main purpose is propulsion assistance. If a vessel primarily carries cargo, even with towing capabilities, it falls under 8901. Similarly, a vessel primarily used for dredging, even if it has some self-propulsion, would be 8905. Another mistake is classifying component parts of tugs, which generally fall under their respective chapter (e.g., engines under Chapter 84) rather than the complete vessel heading.

In 2025, the top exporters of HS code 8904 in UN Comtrade data were Saudi Arabia ($755M, 21% of world exports), China ($538M) and Türkiye ($448M). World exports came to about $3.6B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 8904 in UN Comtrade data were the United Arab Emirates (about $829M, 28% of world imports), Thailand ($299M) and India ($252M). World imports came to about $2.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 8904 is a 4-digit heading under Chapter 89 of the Harmonized System. The first 2 digits (89) identify the chapter, and digits 3-4 (04) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
