Harmonized System Code Classification

The first two digits of the HS code "84" represent nuclear reactors, boilers, machines, 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 equipment and parts thereof: Including generators, transformers, motors, wires and cables, switchgear, lighting equipment, electron tubes, semiconductor devices, telecommunications equipment, broadcasting and television equipment, etc.

Reason for classification:

The classification of this chapter is based on the function and use of the product, that is, 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 electrical signal processing, it is likely to belong to Chapter 84 of the HS code.

The first four digits explain: 8408: Compression-ignition internal combustion piston engines (diesel or semi-diesel engines).

The six-digit explanation: HS code: 8408.10

Classification: Compression-ignition internal combustion piston engines (diesel or semi-diesel engines)

Meaning: Refers to ship propulsion engines with a power output exceeding 746 kW.

Explanation of digits 8-10: HS code: 8408100050
Classification: Compression-ignition internal combustion piston engines (diesel or semi-diesel engines) → Ship propulsion engines
Explanation: Compression-ignition internal combustion piston engines (diesel or semi-diesel engines) with a power output exceeding 746 kW → Ship propulsion engines.

Examples of products: * Diesel ship propulsion engines * Large marine diesel engines * Semi-diesel engines used in ships * High-power marine compression-ignition engines * Heavy-duty diesel engines for ship propulsion * Industrial diesel engines for ship applications * Marine diesel engines with power exceeding 746 kW * Ship propulsion systems using compression-ignition engines * Diesel engines used in large vessels * Marine engines designed for high-output propulsion
