About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This classification covers screws and bolts specifically designed for import or export, where the diameter of their shanks or threads measures less than 6 millimeters. These fasteners are typically used in applications requiring smaller, more precise connections and are of iron or steel construction, fitting within the broader category of threaded articles.

It is crucial to distinguish this category from its sibling, which covers similar fasteners with a shank or thread diameter of 6 millimeters or more. The defining characteristic for differentiation is this precise dimensional threshold, ensuring accurate tariff application based on the physical size of the fastener.

As this is a leaf node in the HTS classification system, there are no further subcategories. Classification within this specific code is determined solely by the material (iron or steel), the type of article (screws and bolts), their threaded nature, and the critical measurement of the shank or thread diameter being less than 6 mm.
