The tariff classification of a robotic pool skimmer from China
Issued March 17, 2026 by U.S. Customs and Border Protection.
Tariff classification
HTS codes: 8421.21.0000
Headings: 8421
Product description
Descriptive literature was provided for our review. The item under consideration is described as a robotic pool skimmer, which is a solar-powered surface cleaning robot designed for automatic pool maintenance. The skimmer is capable of continuously collecting floating debris such as leaves, insects, and dust from the water surface, reducing manual skimming efforts while keeping the pool clean. The device features a hybrid power system combining solar energy with a built-in battery, enabling all-weather operation. When the battery level is low, the robot automatically seeks sunlight to recharge quickly and resumes cleaning. Its roller brush and anti-spill baffle structure capture and secure debris, preventing it from escaping during turns or when approaching pool edges. Collected waste is stored in a filter basket, which is easily removed after use for rinsing and cleaning. Additionally, the robotic pool skimmer has a chlorine tablet box to provide for additional pool water quality balancing. The device weighs 12.6 pounds and measures 21 inches long by 16 inches wide by 8 inches high. The skimmer is imported with the device, charger, user manual, and foam noodle (to prevent the device from getting jammed at the skimmer port).

Descriptive literature was provided for our review. The item under consideration is described as a robotic pool skimmer, which is a solar-powered surface cleaning robot designed for automatic pool maintenance. The skimmer is capable of continuously collecting floating debris such as leaves, insects, and dust from the water surface, reducing manual skimming efforts while keeping the pool clean. The device features a hybrid power system combining solar energy with a built-in battery, enabling all-weather operation. When the battery level is low, the robot automatically seeks sunlight to recharge quickly and resumes cleaning. Its roller brush and anti-spill baffle structure capture and secure debris, preventing it from escaping during turns or when approaching pool edges. Collected waste is stored in a filter basket, which is easily removed after use for rinsing and cleaning. Additionally, the robotic pool skimmer has a chlorine tablet box to provide for additional pool water quality balancing. The device weighs 12.6 pounds and measures 21 inches long by 16 inches wide by 8 inches high. The skimmer is imported with the device, charger, user manual, and foam noodle (to prevent the device from getting jammed at the skimmer port). The applicable subheading for the robotic pool skimmer will be 8421.21.0000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Centrifuges, including centrifugal dryers; filtering or purifying machinery and apparatus, for liquids or gases; parts thereof: Filtering or purifying machinery and apparatus for liquids: For filtering or purifying water.” The general rate of duty will be free.
