Carolyn Leski BCB International Inc 1010 Niagara St Buffalo, NY 14213 RE: The tariff classification of metallized polyethylene terephthalate (PET) radiant barrier sheets from Canada Dear Ms. Leski: In your letter dated January 9, 2026, you requested a tariff classification ruling on behalf of your client, Balcan Innovations, Inc. The products under consideration are referred to as 4800 Series NT Radiant Barrier sheets. The products have a total finished weight of 0.148 kg/m2. The plastic material constitutes 55 percent of the total weight of the sheets. These are described as high-performance reflective insulation intended for use as an insulation or vapor barrier in a variety of construction applications. Part Numbers 4800-48-125S and 4800-48-250S are solid sheet products. The products are composed of a coated woven fabric composed of high-density polyethylene (HDPE) fabric coated on one side with a layer of low-density polyethylene (LDPE). This coated fabric is sandwiched between two layers of metallized polyethylene terephthalate. The metallization is applied by vapor deposition. Part Numbers 4800-48-125P and 4800-48-250P are perforated sheet products. These perforated sheet products are manufactured in the same way as the solid sheet products. However, these sheets undergo additional manufacturing steps to incorporate the perforation. You suggest classification of these products in 3920.62.0050, Harmonized Tariff Schedule of the United States (HTSUS). We disagree. Heading 3920 covers other sheets of plastic that are not reinforced, laminated, supported or combined with other materials. These products contain a center layer of coated textile fabric. Therefore, the sheets are excluded from classification in 3920.62.0050, HTSUS. Further, headings 3920 and 3921, HTSUS, exclude products that have been further worked. Perforation constitutes further work and therefore, the perforated sheets are excluded from classification in 3920, HTSUS and 3921, HTSUS.

The applicable subheading for the metallized PET solid radiant barrier sheets, 4800-48-125S and 4800-48-250S will be 3921.90.1500, HTSUS, which provides for other plates, sheets, film, foil and strip, of plastics: other: combined with textile materials and weighing not more than 1.492 kg/m2: products with textile components in which man-made fibers predominate by weight over any other single textile fiber: other. The general rate of duty will be 6.5 percent ad valorem. The applicable subheading for the metallized PET perforated radiant barrier sheets, 4800-48-125P and 4800-48-250P will be 3926.90.9989, HTSUS, which provides for other articles of plastics and articles of other materials of headings 3901 to 3914: other: other: other. The general rate of duty is 5.3 percent ad valorem. 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.
