About HTS 7020.00.30.00

This line sits within Chapter 70 (Glass and glassware), Section XIII (Stone, Plaster, Cement; Ceramic; Glass), and is catalogued as a tariff line in the USITC 2026 Basic Edition.

The general (MFN / Column 1 General) rate for HTS 7020.00.30.00 is Free, which applies to most trading partners of the United States. No special preferential rate is listed for this line, so FTA origin alone will not reduce the general duty. The Column 2 rate of 55% applies to imports from non-MFN countries such as Cuba and North Korea, a much higher historical "full" tariff. Because the general rate is Free, most imports under this code enter the US without duty, though anti-dumping, countervailing, or Section 301 tariffs can still apply depending on country of origin.
Footnotes: See 9903.88.03. Beyond the published rate, importers should check for Section 201 safeguards, Section 301 China tariffs, and any active AD/CVD orders that can materially change the real landed cost.
