Yes. The US schedule provides a dedicated 10-digit line, 8208403000, specifically for lawnmower blades. All other knives and cutting blades for agricultural, horticultural, and forestry machines, along with their parts, are classified under 8208406000. Importers should confirm the intended machine application to avoid misclassification between these two lines.
The key is demonstrating the blade's designed end use. Technical datasheets, OEM part numbers, machine compatibility lists, and supplier invoices that identify the intended agricultural or forestry machine all help establish classification under 8208.40 rather than 8208.10. Customs may request this documentation during a CF-28 inquiry.
