9902.15.95 - Valves, capable of operating at pressures of 68.94 MPa or more (provided for in subheading 8481.80.90), for controlling production flow through a subsea tree, each mounted in a module that can be removed and replaced by a remotely operated underwater vehicle (ROV)

This HTS classification, 9902.15.95, specifically designates valves designed for high-pressure applications within subsea production systems. These valves are engineered to operate at pressures of 68.94 MPa (megapascals) or more and are integral to controlling the flow of production through a subsea tree. A key characteristic of these valves is their modular design, allowing them to be conveniently removed and replaced by remotely operated underwater vehicles (ROVs), a critical feature for subsea maintenance and operational efficiency.

While the broader HTS system, particularly within Section XXII and Chapter 99, addresses a wide array of temporary legislation, trade agreements, and specific import restrictions, this particular subheading carves out a niche for specialized subsea equipment. Its placement under Chapter 99 signifies its inclusion within provisions that might be subject to modification based on trade policies or specific legislative actions, distinct from the more general commodity classifications found in earlier chapters like Chapter 01 which deals with live animals.

As a leaf node within the HTS database, subheading 9902.15.95 does not have further subdivisions. Therefore, classification under this code is final for valves meeting all the specified criteria: high-pressure operational capability, application in controlling subsea production flow, and the integrated modular design facilitating ROV servicing. This precise definition ensures that only highly specialized equipment of this nature is classified here, differentiating it from general industrial valves or those used in less demanding or non-subsea applications.
