Which CFR title and subchapter is applicable to foreign tank vessels?

The correct reference for foreign tank vessels is found in 46 CFR Subchapter D. This subchapter specifically addresses the regulations concerning the construction, equipment, and operation of tank vessels, including foreign-flagged vessels operating in U.S. waters. It outlines the standards that must be met to ensure safety and environmental protection, which are critical for the operation of tankers that transport hazardous materials. The focus on tank vessels highlights requirements related to the prevention of oil spills and other potential marine hazards associated with the transportation of bulk liquids.

In contrast, other subchapters, like Subchapter A, primarily cover general provisions and definitions related to the entire body of maritime regulations, while Subchapter C relates more specifically to the prevention of pollution from vessels but does not focus solely on tank vessels. Subchapter D is thus essential for understanding the specific requirements and compliance measures that apply to foreign tank vessels that visit U.S. ports or waterways, ensuring they adhere to the established safety and environmental standards.
