8806.21.00.00 - With maximum take-off weight not more than 250 g

This HTS classification, 8806.21.00.00, specifically designates unmanned aircraft designed for remote-controlled flight that have a maximum take-off weight not exceeding 250 grams. These are typically small, lightweight drones or similar aerial vehicles. Examples include miniature hobby drones, micro-surveillance drones, and certain small payload delivery systems where weight is a critical design factor. The primary differentiating factor for this category is its extremely low weight limit.

This category is distinguished from its sibling categories by this precise weight threshold. For instance, 8806.22.00.00 covers unmanned aircraft with a maximum take-off weight exceeding 250 grams but not surpassing 7 kilograms. Similarly, categories 8806.23.00.00, 8806.24.00.00, and 8806.29.00.00 encompass progressively heavier unmanned aircraft, up to and including those exceeding 150 kilograms. The distinction lies solely in the maximum permissible take-off weight, ensuring accurate tariff application based on the aircraft's operational capacity and potential use.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 8806.21.00.00 is definitive once the condition of a maximum take-off weight not exceeding 250 grams for a remotely piloted aircraft is met. Customs officers will rely on manufacturer specifications, certifications, or physical inspection to verify this critical weight parameter for accurate duty assessment.
