Harmonized System Code Classification

The first two digits of the HS code "84" represent nuclear reactors, boilers, machinery, mechanical appliances, and parts thereof.

Specifically, this chapter covers the following main categories:

• Nuclear reactors, boilers, machines, mechanical appliances, and parts thereof: Including various types of nuclear reactors, boilers, steam generators, turbines, engines, pumps, compressors, machine tools, machine tools, agricultural machinery, construction machinery, industrial robots, etc.
• Electrical machinery and parts thereof: Including generators, transformers, motors, wires and cables, switchgear, lighting equipment, electron tubes, semiconductor devices, telecommunication equipment, radio and television equipment, etc.

Reason for classification:

This chapter is classified based on the function and purpose of the product, i.e., whether the product belongs to nuclear energy utilization, energy conversion, power drive, material processing, or the generation, transmission, and reception of electrical signals. It covers various mechanical and electrical equipment that are essential to industrial production and modern society.

In short, if the product is used to generate, convert, transmit, or utilize energy, or to perform mechanical processing, material handling, or the processing of electrical signals, it is likely to fall under Chapter 84 of the HS code.

The six-digit HS code: 8409.91

Classification: Applicable to parts for engines under headings 8407 or 8408: --> Other: --> Suitable for use solely or mainly with spark-ignition internal combustion piston engines (including rotary engines): --> Other: --> Other --> Other

Meaning: This HS code applies to parts for engines under headings 8407 or 8408, particularly those used exclusively or mainly with spark-ignition internal combustion piston engines (including rotary engines), and is a more detailed subcategory under the "Other" category.

8-10 digit HS code: 8409915081

Classification: Parts suitable for use solely or principally with the engines of heading 8407 or 8408: --> Other: --> Suitable for use solely or principally with spark-ignition internal combustion piston engines (including rotary engines): --> Other: --> To be installed in vehicles of subheading 8701.21, 8701.22, 8701.23, 8701.24 or 8701.29, or heading 8702, 8703 or 8704: --> Other --> Steel forgings

Explanation: This HS code applies to parts for engines under headings 8407 or 8408, specifically parts suitable for spark-ignition internal combustion piston engines (including rotary engines), further limited to parts installed in vehicles under subheadings 8701.21, 8701.22, 8701.23, 8701.24 or 8701.29, or under headings 8702, 8703 or 8704, and finally classified as steel forgings.

Examples of products: * Piston rings for internal combustion engines * Connecting rods for automotive engines * Crankshaft forgings for passenger vehicles * Valve springs for spark-ignition engines * Camshaft parts for rotary engines * Cylinder head components for gasoline engines * Steel forgings used in engine blocks * Transmission parts for vehicles * Starter motor parts for internal combustion engines * Fuel injection pump components for diesel engines
