The tariff classification of a lithium-polymer battery from China

N359659 March 31, 2026 CLA-2-85:OT:RR:NC:N1:103 CATEGORY: Classification TARIFF NO.: 8507.60.0090 Joanne Eustache The Swatch Group (U.S.) Inc. Renata Batteries 800 Waterford Way, Suite 1000 Miami, FL 33126 RE: The tariff classification of a lithium-polymer battery from China Dear Ms. Eustache: In your letter dated March 11, 2026, you requested a tariff classification ruling. The merchandise under consideration is identified as a rechargeable lithium polymer battery, part number ICP241019, and is described as an ultra-thin, rectangular pouch cell with lead wires. It measures approximately 18.5 millimeters in length, 11.2 millimeters in width, and 2.4 millimeters in thickness. In the United States, the battery will be incorporated into a glucose sensor transmitter, which is a component of a glucose monitoring system. The function of the glucose sensor transmitter is to gather data, such as voltages, electrochemical impedance, and other readings, which are then transmitted to a display device. The battery powers the transmitter and has a nominal voltage of 3.7 VDC and a nominal capacity of 25 mAh. The applicable subheading for the lithium polymer battery, part number ICP241019, will be 8507.60.0090, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Electric storage batteries, including separators therefor, whether or not rectangular (including square); parts thereof: Lithium-ion batteries: Other: Other.” The general rate of duty will be 3.4 percent ad valorem. In your submission you requested consideration of a secondary classification under 9817.00.96, HTSUS, which applies to articles and parts of articles specifically designed or adapted for the use or benefit of the permanently or chronically physically or mentally handicapped. Subheading 9817.00.96, HTSUS, covers: “Articles specially designed or adapted for the use or benefit of the blind or other physically or mentally handicapped persons; parts and accessories (except parts and accessories of braces and artificial limb prosthetics) that are specially designed or adapted for use in the foregoing articles . . . Other.” The term “blind or other physically or mentally handicapped persons” includes “any person suffering from a permanent or chronic physical or mental impairment which substantially limits one or more major life activities, such as caring for one’s self, performing manual tasks, walking, seeing, hearing, speaking, breathing, learning, or working.” U.S. Note 4(a), Subchapter XVII, Chapter 98, HTSUS. Subheading 9817.00.96, HTSUS, excludes “(i) articles for acute or transient disability; (ii) spectacles, dentures, and cosmetic articles for individuals not substantially disabled; (iii) therapeutic and diagnostic articles; or, (iv) medicine or drugs.” U.S. Note 4(b), Subchapter XVII, Chapter 98, HTSUS. In Sigvaris, Inc. v. United States, 227 F. Supp 3d 1327, 1336 (Ct. Int’l Trade 2017), aff’d, 899 F.3d 1308 (Fed. Cir. 2018), the U.S. Court of International Trade (CIT) explained that “specially” means “to an extent greater than in other cases or towards others” and “designed” means something that is “done, performed, or made with purpose and intent often despite an appearance of being accidental, spontaneous, or natural.” We must first evaluate “for whose, if anyone’s, use and benefit is the article specially designed,” and then, whether “those persons [are] physically handicapped [].” Sigvaris, 899 F.3d at 1314. The Court of Appeals for the Federal Circuit (CAFC) clarified in Sigvaris, 899 F.3d at 1314-15 that to be “specially designed,” the merchandise “must be intended for the use or benefit of a specific class of persons to an extent greater than for the use or benefit of others” and adopted the following five factors used by U.S. Customs and Border Protection (CBP): (1) the physical properties of the article itself (i.e., whether the article is easily distinguishable by properties of the design, form, and the corresponding use specific to this unique design, from articles useful to non-handicapped persons); (2) whether any characteristics are present that create a substantial probability of use by the chronically handicapped so that the article is easily distinguishable from articles useful to the general public and any use thereof by the general public is so improbable that it would be fugitive; (3) whether articles are imported by manufacturers or distributors recognized or proven to be involved in this class or kind of articles for the handicapped; (4) whether the articles are sold in specialty stores which serve handicapped individuals; and, (5) whether the condition of the articles at the time of importation indicates that these articles are for the handicapped. Based on the information supplied, the subject lithium polymer battery does not satisfy the five factors set out by CBP. The lithium polymer cell is not specially designed or adapted for a specific device, and appears indistinguishable from other ultra-thin pouch cells, which are a common form factor used in various applications. It is not specially shaped and is not fitted with proprietary connectors. The specialized attributes, described as being small in physical dimensions and having short tabs, are not significant enough to clearly render the article for use in a particular device for the handicapped. As a result, it is the opinion of this office that a secondary classification will not apply under subheading 9817.00.96, HTSUS. 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.

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 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. This ruling is being issued under the provisions of Part 177 of the Customs and Border Protection Regulations (19 C.F.R. 177).
