Tanks, Vessels, and Gas Cylinders: Statutory & Effective Tariff Rates

USITC Column 1 General rates for 5 tanks, vessels, and gas cylinders HTS lines (parseable range 0%). Effective rate Jun 2026: 40.17%; monthly history since 2014.

The short answer

The observed effective calculated-duty rate on U.S. imports of tanks, vessels, and gas cylinders was 40.17% in Jun 2026, up from 32.52% a year earlier — USITC Calculated Duties divided by covered customs value. The Column 1 General line-rate range is 0% across 5 HTS lines in the 2026 schedule; individual lines are called “Free” only when the official General field is literally Free, which still does not determine a shipment’s final duty. Mexico is the largest source, holding 20% of 2025 imports.
