Draft Gear Buffer Assembly
Draft gear buffer assemblies include friction housings and elastomeric pads that cushion coupling impacts on 8605/8606 locomotives and rolling stock. They mount within the coupler pocket to manage longitudinal forces. HTS 8607.30.10 includes these as parts of buffers and coupling devices.

Import Tips & Compliance
• Provide load testing data showing compliance with 50 CFR Part 231 standards for freight car buffers
• Avoid bulk packaging without vehicle-specific markings, as it risks reclassification as general steel parts
• Declare exact composition (e.g
• steel/urethane) to counter potential Chapter 73 material-based claims
