CPC v2.1 Code: 42998

About ships' propellers and blades therefor

cpc code 42998 covers the production and trade of ships' propellers and their blades. This industry plays a crucial role in the maritime transportation sector, which is a key driver of global trade and economic activity. Ships' propellers are essential components that provide the thrust needed to power vessels, making them indispensable for the efficient movement of goods and people across oceans and waterways worldwide.

Production process

The production of ships' propellers and blades typically involves a combination of casting, forging, and machining processes. Manufacturers often start with raw metal alloys, such as 42101 Copper and copper alloy ingots, blocks, slabs and sheets, which are then melted and poured into molds to create the initial propeller shape. The cast propellers are then subjected to various finishing operations, including grinding, polishing, and balancing, to ensure optimal performance and efficiency.

Production inputs

In addition to the primary raw material inputs, the production of ships' propellers and blades requires specialized machinery and equipment, such as 44201 Metalworking machinery, as well as skilled labor to operate these tools and perform the necessary manufacturing steps. Energy sources, such as electricity or natural gas, are also essential for powering the production facilities and equipment.

Production outputs

The primary output of cpc code 42998 is the finished ships' propellers and blades, which are then sold to 34300 Ship and boat building and repairing, 34400 Manufacture of aircraft and spacecraft and related machinery, and other industries that require these critical components for their vessels. The propellers and blades produced under this code are essential for the efficient and reliable operation of a wide range of watercraft, from commercial cargo ships to naval vessels and recreational boats.
