8208.40 - For agricultural, horticultural or forestry machines, and parts thereof:

This HTS category, 8208.40, specifically covers knives and cutting blades, along with their base metal parts, designed for use in agricultural, horticultural, or forestry machines. This includes blades intended for machinery that cultivates soil, harvests crops, manages gardens and landscapes, or processes timber. The primary function of these items is to perform cutting, chopping, or shredding operations within these specialized mechanical appliances.

Unlike sibling categories that focus on blades for metalworking (8208.10), woodworking (8208.20), or food industry applications (8208.30), this section is dedicated to blades integral to machines operating within the primary production sectors of agriculture, horticulture, and forestry. The distinguishing factor is the intended application and the specific type of machinery the blades are designed to fit and function within.

Within this category, further subdivisions exist to refine classification. The subcategory 8208.40.30.00 specifically enumerates lawnmower blades, recognizing their distinct application. The remaining items, including various other cutting blades and all parts thereof not specifically listed as lawnmower blades, fall under the residual category of 8208.40.60.00, ensuring comprehensive coverage for all relevant agricultural, horticultural, and forestry machine blades and their components.
