RE:      The tariff classification of galvanized steel sheets from South Korea

Dear Mr. Nonis:

In your letter dated January 17, 2024, you requested a tariff classification ruling.

The products under consideration are cold-rolled, zinc-coated, nonalloy steel sheets. You indicate that these hot-dipped galvanized steel sheets are made to ASTM 653 and will be used primarily in HVAC duct fabrication. The sheets measure 0.47 mm, 0.51 mm or 0.63 mm in thickness, 1219 mm or 1524 mm in width and will be imported in either 8 foot or 10-foot lengths.

The applicable subheading for the galvanized nonalloy steel sheets will be 7210.49.0091, Harmonized Tariff Schedule of the United States, (HTSUS), which provides for Flat-rolled products of iron or nonalloy steel, of a width of 600 mm or more, clad, plated or coated: Otherwise plated or coated with zinc: Other: Other: Of a thickness of 0.4 mm or more. The rate of duty will be free.

On March 8, 2018, Presidential proclamations 9704 and 9705 imposed additional tariffs and quotas on a number of steel and aluminum mill products. Exemptions have been made on a temporary basis for some countries. Quantitative limitations or quotas may apply for certain exempted countries and can also be found in Chapter 99. Additional duties for steel of 25 percent and for aluminum of 10 percent are reflected in Chapter 99, subheading 9903.80.01 for steel and subheading 9903.85.01 for aluminum. Products classified under subheading 7210.49.0091, HTSUS, may be subject to additional duties or quota. At the time of importation, you must report the Chapter 99 subheading applicable to your product classification in addition to the Chapter 72, 73 or 76 subheadings listed above.

Please be advised that the zinc-coated nonalloy steel sheets may be subject to antidumping duties and/or countervailing duties. Written decisions regarding the scope of AD/CVD orders are issued by the Enforcement and Compliance office in the International Trade Administration of the Department of Commerce (ITA) and are separate from tariff classification and origin rulings issued by Customs and Border Protection (CBP). General information regarding the ITA and AD/CVD can be found at The ITA’s “Guide on How to File for an Antidumping/Countervailing Duty Scope Ruling Request” is available at

The holding set forth above applies only to the specific factual situation and merchandise description as identified in the ruling request. This position is clearly set forth in Title 19, Code of Federal Regulations (CFR), Section 177.9(b)(1). This section states that a ruling letter is issued on the assumption that all of the information furnished in the ruling letter, whether directly, by reference, or by implication, is accurate and complete in every material respect. In the event that the facts are modified in any way, or if the goods do not conform to these facts at time of importation, you should bring this to the attention of U.S. Customs and Border Protection (CBP) and submit a request for a new ruling in accordance with 19 CFR 177.2. Additionally, we note that the material facts described in the foregoing ruling may be subject to periodic verification by CBP.
