8511.90.60 - Other parts

HTS Code 8511.90.60 encompasses "Other parts" pertaining to electrical ignition or starting equipment for internal combustion engines, as well as generators and cut-outs used in conjunction with these engines. This classification acts as a residual category, capturing components not specifically enumerated within the more detailed subheadings of 8511. These parts are integral to the functioning of ignition systems, starter motors, dynamos, alternators, and voltage regulators designed for spark-ignition and compression-ignition internal combustion engines.

This category is distinct from the sibling category "Of voltage and voltage-current regulators with cut-out relays." While both fall under the broader heading of parts for engines, 8511.90.60 specifically excludes parts that are exclusively part of a voltage regulator with a cut-out relay. Instead, it focuses on a wider array of replacement or component parts that are not so specifically defined.

Within the "Parts" heading of 8511, this category is further subdivided to provide greater specificity. The subcategory 8511.90.60.20 covers distributor contact (breaker point) sets, which are crucial for timing the ignition spark in older ignition systems. All other parts not falling under breaker point sets or the voltage regulator sibling are classified under the residual subheading 8511.90.60.40, "Other." This hierarchical structure allows for precise classification of various components, from the smallest electrical contacts to larger mechanical or electrical sub-assemblies.
