Choosing a Contract Manufacturer: Study Guide

Read our guide to choosing a contract manufacturer, then write a question list and a comparison sheet you could send to two real candidates tomorrow.

In short

Choosing a contract manufacturer means comparing capability, documented quality, minimum orders, responsibilities and how they protect your formula, as well as price. The guide sets out those criteria. You do not need a real project to learn this, because writing the questions shows you what you would need to know, and what you do not yet know about your own product.

What you will learn

  • Compare manufacturers using written criteria
  • Ask who is responsible for what

Before this lesson: Manufacturing Considerations: Study Guide

What to look for as you read

  • Which responsibilities can be contracted, and which stay with you as a brand.
  • Which claims should come with evidence.
  • How you would keep your formula confidential.

Practical exercise: A candidate comparison sheet

About 40 minutes · You will have: a question list and a comparison sheet with your weighting

  1. Write a short description of an imagined product: volume, market and fill.
  2. List twelve questions under capability, quality, compliance, cost, confidentiality and timing.
  3. Build a comparison sheet, and weight the columns by what matters to this product. Write the reason for your top weighting.
  4. Find two real candidates, and fill in what you can from public information. Do not contact them unless you actually have a project.
  5. Mark everything that would require a direct answer or a site visit.

You have done this well if your weighting was written before you looked at candidates, and each filled cell has a source and date.
