How do I know the BOM (Bill of Material)?

If you don’t have all the BOM details from your supplier, don’t worry, there are several ways to make a good estimation. The goal is to get as close as possible with the information available, so you can start your analysis and refine it later.

1. Check existing information

• Look for ingredient lists, specifications, or labels provided by the supplier or printed on the packaging.

• Sometimes, the product datasheet or technical documentation includes useful clues about the materials or components used.

2. Ask your supplier

• Contact the supplier directly to request missing BOM details.

• Even if they can’t share exact formulations, see if they can share general information such as the high-over composition or weight. 

3. Make your best estimate

• Use your own knowledge or similar products as a reference.

• Try to identify the main components and approximate their proportions (for example: 70% steel, 20% plastic, 10% rubber). You are then able to recalculate them into weights. 

4. Use AI assistance

• You can use an AI tool to help estimate the BOM if you lack data.

• Upload a photo, share a link, or describe the product in detail.

• The AI can help estimate:

  • The weight of one product

  • The weight ratios of each commodity or material

  • Possible composition breakdowns based on product characteristics

Even a first estimation is a valuable starting point. It helps you challenge the supplier and refine the details together by asking targeted questions.
