N353154 September 25, 2025 CLA-2-90:OT:RR:NC:N3:135 CATEGORY: Classification TARIFF NO.: 9019.20.0000; 9817.00.96 Degang Wang WeOxy Co., LTD 110 Cedar Street, STE 105 Wellesley, MA 02481 RE: The tariff classification of portable oxygen concentrators from China Dear Mr. Wang: In your letter dated September 2, 2025, you requested a tariff classification ruling. Additional information was provided by email dated September 29, 2025. WeOxy Q series (WeOxy Q4, WeOxy Q5, WeOxy Q6, and WeOxy Q7), previously known as Inogi W-series, portable oxygen concentrators (POCs) are medical-grade oxygen therapy devices designed to supply concentrated oxygen (90% - 3% / + 5.5%) from ambient air using molecular sieve technology. The devices deliver oxygen in pulse-dose mode across multiple flow settings. Delivery is automatically triggered by the patient’s inhalation, supporting mobility and daily use. The principal use of the devices is to provide long-term supplemental oxygen therapy as prescribed by physicians for patients with chronic respiratory impairments such as Chronic Obstructive Pulmonary Disease (COPD). They measure 6.9 x 3.0 × 7.6 inches (L x W x H) and weigh 3.97 lbs. Each imported POC is packed in a retail box and further enclosed in a shipping carton. It includes a main POC unit with a rechargeable lithium-ion battery, a DC car charger, a pulse oximeter, an AC power supply/charger and cord, an extra battery charger, a carrying bag, a shoulder strap, backpack-style straps, a belt, an accessory bag with spare cotton filters, replacement stickers, and a hex wrench. The applicable subheading for the WeOxy Q series portable oxygen concentrators will be 9019.20.0000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “[o]zone therapy, oxygen therapy, aerosol therapy, artificial respiration or other therapeutic respiration apparatus; parts and accessories thereof.” The general rate of duty will be free. Effective March 4, 2025, pursuant to U.S. Note 2(u) to Subchapter III, Chapter 99, all products of China and Hong Kong as provided by heading 9903.01.24, HTSUS, other than products classifiable under headings 9903.01.21, 9903.01.22, and 9903.01.23, HTSUS, will be subject to an additional 20 percent ad valorem rate of duty. At the time of entry, you must report the applicable Chapter 99 heading, i.e. 9903.01.24, in addition to subheading 9019.20.0000, HTSUS, listed above. Effective April 5, 2025, Executive Orders implemented “Reciprocal Tariffs.” All imported merchandise must be reported with either the Chapter 99 provision under which the reciprocal tariff applies or one of the Chapter 99 provisions covering exceptions to the reciprocal tariffs. At this time products of China, Hong Kong, and Macau will be subject to an additional 10 percent ad valorem rate of duty. At the time of entry, you must report the Chapter 99 heading applicable to your product classification, i.e. 9903.01.25, in addition to subheading 9019.20.0000, HTSUS, listed above. However, the additional duties imposed by heading 9903.01.24 or 9903.01.25 shall not apply to goods for which entry is properly claimed under a provision of chapter 98 of the tariff schedule pursuant to applicable regulations of U.S. Customs and Border Protection (“CBP”), and whenever CBP agrees that entry under such a provision is appropriate, except for goods entered under heading 9802.00.80; and subheadings 9802.00.40, 9802.00.50, and 9802.00.60. In your submission you requested consideration of a secondary classification under 9817.00.96, HTSUS, which applies to articles and parts and accessories 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: “[a]rticles 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: [o]ther.” 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 United States 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 five factors used by 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. In Headquarters Ruling Letter (HQ) H301481, dated June 14, 2019, CBP concluded that the specific class of persons for which Inogen’s portable oxygen concentrator was intended was physically handicapped and determined that the portable oxygen concentrator qualified for duty-free treatment under subheading 9817.00.96, HTSUS. The WeOxy Q series portable oxygen concentrators are almost identical to Inogen’s portable oxygen concentrator and for the same use. It is the opinion of this office they are also eligible for duty-free treatment under subheading 9817.00.96, HTSUS. The tariffs and additional duties cited above are current as of this ruling’s issuance. Duty rates are provided for your convenience and are subject to change.

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.
