Annelori Roder Littelfuse Inc. 6133 N River Road, Suite 500 Rosemont, IL 60018 RE: The tariff classification of electrostatic discharge (ESD) suppressors from the Philippines Dear Ms. Roder: In your letter dated July 15, 2026, you requested a tariff classification ruling. The merchandise under consideration in this request are three versions of Littelfuse ESD suppressors, identified individually as model numbers AXGD1, PGB1, and XGD. All three models are described as one-channel, bidirectional polymer ESD protection devices designed for sensitive electronic equipment and high-speed dataline applications. In use, the devices are surface mounted within electronic assemblies or circuit board assemblies to suppress fast-rising electrostatic discharge transients while preserving signal integrity and minimalizing data loss. All models are rated at a maximum DC voltage of 24V. In your request, you suggest the ESD suppressors are classifiable under subheading 8536.30.8000, Harmonized Tariff Schedule of the United States (HTSUS). We agree. The applicable subheading for the ESD suppressors will be 8536.30.8000, HTSUS, which provides for “Electrical apparatus for switching or protecting electrical circuits…for a voltage not exceeding 1,000V: Other apparatus for protecting electrical circuits: Other.” The general 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.
