This sector is also sensitive to fluctuations because the price of raw materials, such as gold or other metals, is largely demand driven. The basic materials sector is responsible for the physical acquisition, development and initial processing of products commonly referred to as raw materials. Often, these are naturally occurring substances and resources. They can also be seen as finite in nature to some degree; though the materials may be reusable, they are not available in infinite quantities at any given point in time.
Some of the most common materials covered within the basic materials sector include any mined materials, such as metals and ore, as well as forestry products, such as lumber. Certain chemical producers and energy sources also qualify as part of the basic materials sector. Not all businesses that work with basic materials qualify as part of the sector. For example, while metal mining is considered a basic materials processor, a jeweler, even if it only works with the mined metal, is not. Instead, it is a user of the basic material.
Qualifying Chemicals —
Not all chemicals qualify as basic materials, such as complex cleaning products or pharmaceuticals. Instead, this category includes items such as industrial fertilizer and paint additives.
Energy Sources —
Certain energy sources, such as natural gas , are considered basic materials. Crude oil and coal qualify in their natural state, as well as certain refined products such as gasoline. The more refined versions are included due to the significance in the operation of basic industry. Even though they go through significant processing, they are critical for operation of almost every type of industry.
Basic Materials Sector and Economical Shifts —
The basic materials sector is subject to in the same way as consumer goods. If the demand for associated consumer goods drops, the demand for the raw materials involved in the production of those goods also drops.
