RE: The tariff classification of a cleanroom panel from China
Dear Ms. Wallace:
In your letter dated February 13, 2026, you requested a tariff classification ruling on behalf of your client,
Boviet Solar Technology.
The product under consideration is a cleanroom panel, part of a "CLEANROOM PARTITION SYSTEM,"
which is designed to form walls and/or ceilings within cleanroom environments. These "sandwich" style
panels are constructed with color-coated steel sheet facings, typically 0.4 mm to 0.6 mm thick and coated
with PVDF, bonded to a rock wool (mineral wool) core. Metal edge/corner elements, specifically 0.5 mm
galvanized steel corners, and grid/frame elements (0.6 mm to 0.8 mm thick) are integrated, with all
components secured by a two-component polyurethane foam adhesive. By weight, the panels are
approximately 15 kg per square meter, comprising about 56% color-coated/galvanized steel (including skins,
corners, and mesh/frame elements), 43% rock wool core material, and 1% polyurethane adhesives and other
materials. These panels are imported as finished, single units, already cut to their final installation size, with
molded edges for easy assembly, and include necessary fasteners. They are packaged on plywood pallets.
The applicable subheading for the cleanroom panel will be 7308.90.9590, Harmonized Tariff Schedule of
United States (HTSUS), which provides for Structures (excluding prefabricated buildings of heading 9406)
and parts of structures (for example, bridges and bridge sections, lock gates, towers, lattice masts, roofs,
roofing frameworks, doors and windows and their frames and thresholds for doors, shutters, balustrades,
pillars and columns) of iron or steel; plates, rods, angles, shapes, sections, tubes and the like, prepared for use
in structures, of iron or steel: Other: Other: Other: Other: Other. The rate of duty will be free.
The duties cited above are current as of this ruling’s issuance. Duty rates are provided for your convenience
and are subject to change. The text of the most recent HTSUS and the accompanying duty rates are provided
at https://hts.usitc.gov/.
This ruling does not address the applicability of any additional duties, taxes, fees, exactions and/or other
charges, which may apply to the goods discussed herein. This includes, but is not limited to, tariffs and other
duties as provided for in Subchapter III to Chapter 99, HTSUS. Thus, for example, in addition to the
classification stated above, the merchandise covered by this ruling may also need to be reported with either
the Chapter 99 provision under which an additional tariff applies or one of the Chapter 99 provisions
covering exceptions to such tariffs.
