RE: The tariff classification of stone paper corrugated boxes from China Wang Bule Guangzhou SIRUIER Green Packaging Technology Co., Ltd. Room 1601-05, Building B3, CIMC Greater Bay Area(GBA) International Talent Innovation Park, No.42 Dongzhong Road, Huangpu District, Guangzhou City Guangdong Province, China Dear Mr. Bule: In your letter dated June 30, 2026, you requested a tariff classification ruling. The products under consideration are described as stone paper corrugated boxes. You state that the stone paper boxes contain 70 to 80 percent by weight calcium carbonate and 20 to 30 percent by weight polyethylene. The stone paper corrugated boxes are designed and used to package and ship various goods. In your request, you state that the stone paper corrugated boxes would be classified under subheading 4819.10.0040, Harmonized Tariff Schedule of the United States (HTSUS), which provides for Cartons, boxes, cases, bags and other packing containers, of paper, paperboard, cellulose wadding or webs of cellulose fibers; box files, letter trays and similar articles, of paper or paperboard of a kind used in offices, shops or the like: Cartons, boxes and cases, of corrugated paper or paperboard: Other. We disagree. The stone paper boxes are not constructed of cellulose-based paper. The applicable subheading for the stone paper corrugated boxes will be 3923.10.9000, HTSUS, which provides for articles for the conveyance or packing of goods, of plastics: boxes, cases, crates and similar articles: other. The general rate of duty will be 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.

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.
