What to Include in Bill of Materials?

Every small detail that goes into making a product must be clearly stated in the bill of materials to avoid sample preparation errors that can make the process costly and time-consuming. For example, let’s say you make a bespoke hook and bar fastener pants. Ensure all the details such as the hinge, hook, and rod are included in the bill of materials. Add supporting documentation, such as B. CAD drawings (Computer-Aided Design), parts datasheets and assembly instructions. The more specific you are, the more accurate you will get the sample. If your bill of materials is easy to read and complete, your factory will have a better idea of ​​the finished product.

The bill of materials is also specific to each color. If you have three color options, you’ll need a parts list for each color.

Other essential elements of a useful bill of materials:

1) All parts must be assigned unique numbers and names so that they can be easily traced.

2) BOM level: the hierarchy of the part or assembly;

3) The exact nature of the material must be specified, including embellishments, embellishments and notions.

4) Color. Add a Pantone number to make sure the correct color is used.

5) Labels and packaging: hang tags, care labels, size labels, label thread, pens, handkerchiefs, plastic bags and desiccant bags, etc.

6) Quantity of each part used in each assembly;

7) Unit cost: the unit cost of the piece;

8) Unit of measure. Standard dimensions include parts, centimeters, inches, feet, and yards;

9) Description: additional information about each part;

10) Who approves the bill of materials by the approval date?

11) Total number and total cost;

12) Supplier. Make a note of the name and contact details of the supplier who delivered the parts so you can easily access them if you need to order more.

13) A bill of materials can contain the number of parts needed to make a finished product and an estimate of the waste generated during the production process. Waste is excess unusable material that is left behind after a product is made. This remainder has minimal value and is usually sold for its material content. A company can reduce the amount of waste it generates by paying close attention to setting up production facilities, purchasing raw materials of appropriate quality, and training employees in the correct use of production facilities.

14) It can also include processing required (sponging, dyeing, etc.) and test results like fabric shrinkage. Some fabrics tend to shrink during the manufacturing process. So it is essential to do some research on the substances to be used and do some tests, e.g., B. Pre-wash the fabric before sewing the garment.
