A straddle carrier straddles its load and lifts by spanning the container from above using a frame structure, while a reach stacker uses a telescoping boom and spreader to pick containers from the side. This mechanical distinction drives different HTS classification; misclassifying one as the other can result in duty discrepancies. A licensed customs broker should review engineering specifications before filing.

Straddle carriers and mobile lifting frames are heavy capital goods, and depending on origin, they may be subject to Section 301 tariffs (for goods of Chinese origin) or other trade-remedy measures. Buyers sourcing from multiple origins should conduct a country-of-origin analysis, particularly when components are sourced from one country and assembled in another.
