Every other product we use has been produced by using some or the other raw materials. It is the most crucial component of inventory for any manufacturing unit and therefore, managing inventory of raw materials becomes crucial too. For example, natural latex obtained from trees is used to make several finished products such as mattresses, gloves, balloons, rubber bands, tennis shoes, etc.
In short, an unprocessed or minimally processed material (obtained as mineral ores, natural oil, agricultural product) that undergoes a transformation for creating a finished product in vast quantities is called a raw material.
Let’s take a look at some formal definitions of raw materials-
The Oxford Dictionary defines raw materials as “The basic material from which a product is made.” but that is a simple way to put it for basic understanding.
However, Wikipedia defines raw materials further,
“A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished products, energy, or intermediate materials that are feedstock for future finished products.”
Though all the raw materials are obtained naturally, they can be divided into 3 types based according to where it is derived from.
- Plant/tree-based – materials like vegetables, fruits, flowers, wood, resin, latex are obtained from plants and trees.
- Animal-based– materials like leather, meat, bones, milk, wool, silk are all obtained from animals.
- Mining-based– materials like minerals, metals, crude oil, coal, etc. are obtained by mining the earth.
Apart from this, a manufacturing unit divides the raw materials into 2 main categories.
- Direct raw materialsThe primary component from which a finished product is made is called direct raw materials.For example, wood is a direct raw material from which furniture like chair, tables, bed, etc. are made. Another example is leather used for making purses, shoes, bags, etc.
- Indirect raw materialsOn the other hand, indirect raw materials are the materials that supplement in making the finished product from the direct materials.For example, the glue, nails, varnish, etc. used in making wooden furniture like chair, table, bed, etc. are all indirect raw materials. Similarly, the buckles, metal hoops, zips, glue, lining fabric, colors, etc. used in making leather purses, shoes, and bags are all indirect raw materials.
From the above-discussed definition and meaning, it is clear that producing any finished product requires raw materials, which are then processed and made into finished goods.
This is where inventory management comes into the picture. It is important to maintain raw materials inventory in the proper quantity and at the right place to avoid any mishaps since the finished products that we sell are made from these materials.
Now, coming onto some essential formulas to use for calculating raw materials.
To know how much raw material is used in the manufacturing process, we can use the below formula:
Opening raw material + raw material purchases – closing raw material
= Raw material used
Opening raw materials worth – $ 12000
Raw materials purchased worth – $ 5000
Closing raw materials – $ 9000
So let us calculate as per the above formula,
12000 + 5000 – 9000 = 8000
Thereby, when we apply the formula the result will be the raw material worth $ 8000 were used in the process.
All the closing stock worth, opening stock worth, materials purchase worth is taken from the balance sheet.
The formula used to get the closing stock of raw materials is as follows.
Opening raw materials + raw material purchases – raw material used = Closing raw materials
Let’s understand this with the help of an example,
Suppose Star Manufacturing Company has
Opening raw materials worth – $ 12000
Raw materials purchased worth – $ 5000
Raw material used worth – $ 8000
Therefore, as per the formula,
12000 + 5000 – 8000 = 9000
Hence, closing raw materials worth $9000 is with Star Manufacturing company.
