Custom Knitwear Manufacturing: OEM vs ODM Explained

If you are developing a knitwear collection for your clothing brand, choosing between OEM and ODM manufacturing can affect product development, design control, sampling and production planning. Understanding the difference helps you communicate your requirements clearly and select a manufacturing approach that fits your business.

Custom knitwear manufacturing allows brands, retailers and wholesalers to develop sweaters, cardigans and other knitted garments for their target markets. Depending on the project, a buyer may already have a finished design or may need help turning an initial idea into a production-ready garment.

In this guide, we explain how OEM and ODM knitwear manufacturing work, what information to prepare before requesting a quotation, and which details to confirm before approving a sample or bulk order.

1. What Is Custom Knitwear Manufacturing?

Custom knitwear manufacturing is the process of developing and producing knitted garments according to a buyer's product, material, fit, branding and quality requirements.

Depending on the product, the project may involve yarn selection, knit structure, garment measurements, sample development, linking, finishing, labeling and packaging. Not every project requires the same level of customization.

For example, a clothing brand developing a new sweater design may need to provide a technical pack and reference sample. Another buyer may have a concept image and need the manufacturing partner to help review the yarn, construction and measurements before a sample can be made.

Before choosing a production model, consider how much of the product design has already been completed and which decisions still require development support.

2. What Is OEM Knitwear Manufacturing?

OEM stands for Original Equipment Manufacturer. In a typical OEM knitwear project, the buyer provides the design or product specifications, while the manufacturer develops the garment for production according to the agreed requirements.

The buyer may provide some or all of the following information:

• Technical drawings, design sketches or reference garments
• Garment measurements and size specifications
• Preferred yarn composition and color references
• Knit structure, construction and finishing requirements
• Brand logo, labels, hangtags and packaging artwork
• Target quantity, delivery schedule and quality requirements

The manufacturer reviews the requirements, assesses production feasibility, develops samples and works toward the approved specifications. Some technical details may need discussion or adjustment before bulk production.

When is OEM a suitable choice?

OEM may be suitable when your brand has a defined product concept, existing designs or a technical team that can provide detailed requirements. It can also be appropriate when the fit, stitch details, materials or other product characteristics are important to your brand identity.

Even when you have a complete technical pack, confirm whether the manufacturer can produce the required construction and materials before committing to an order.

3. What Is ODM Knitwear Manufacturing?

ODM stands for Original Design Manufacturer. In an ODM project, the manufacturer generally contributes more to design development or starts from existing design options or product-development resources.

A buyer may begin with a reference photograph, a general design direction, a target customer or a product idea rather than a fully completed technical pack.

Depending on the supplier's actual capabilities, development discussions may cover:

• Suitable yarn options and material specifications
• Garment shape, fit and measurements
• Knit structure and construction options
• Color selection and design adjustments
• Sampling and revisions before approval
• Brand labels and packaging requirements

When is ODM a suitable choice?

ODM may be worth considering when your business has a product idea but needs additional technical or design-development input. It can also be useful for buyers entering a new knitwear category without an established internal product-development team.

However, do not assume every manufacturer offers a full ODM design service simply because it uses the term ODM. Ask what the supplier can actually develop, what is included in the quotation and which decisions remain your responsibility.

4. OEM vs ODM: What Are the Main Differences?

These are general working distinctions rather than universal legal definitions. Actual responsibilities can overlap. A buyer may provide an original design while asking the manufacturer to recommend yarn or improve a construction detail.

The important point is to agree on the scope of development, the final specifications, approval responsibilities and design rights before work begins.

5. Is Private Label the Same as OEM or ODM?

Private label describes how the finished product is sold: under the buyer's own brand. It does not, by itself, explain who created the original design.

A private-label knitwear project may use a buyer-developed design, a design developed with the manufacturer's help or an existing style that can be customized within the supplier's available options.

Depending on the agreement, private-label requirements may include:

• Woven brand labels and care labels
• Hangtags and brand-specific packaging
• Selected colors, materials and product details
• Size labels and product identification
• Approved garment specifications and quality standards

Before proceeding, clarify which product features can be customized and whether any design or style is exclusive to your business. Do not assume that applying your label automatically gives you exclusive ownership of the underlying garment design.

6. How to Choose the Right Manufacturing Model

Choose OEM when you have a defined design

If your team has a technical pack, measurements, material requirements and a clear design direction, OEM may be a practical starting point. You can focus the discussion on production feasibility, sampling, quality requirements and cost.

Consider ODM when you need development support

If you have reference images or a product concept but need help developing the specifications, ask whether the supplier can support the relevant development steps. Confirm the development charges, sample process and responsibilities before work begins.

Consider a combination when your project needs both

Some projects combine buyer-led design with manufacturer recommendations. For example, a brand may provide the sweater design but ask the production team to recommend yarn alternatives or review whether a particular stitch structure is practical.

You do not need to select a label before discussing the actual work. Explain what you already have, what you need help with and what must remain unchanged. The manufacturer can then clarify which services are available.

7. Understand MOQ, Sampling and Production Costs

The minimum order quantity (MOQ), sample charges and production costs depend on the product and the supplier's terms. They may be affected by yarn, colors, construction complexity, size breakdown, labels and packaging.

Mierden's stated starting MOQ is 500 pieces per style. Confirm the applicable MOQ for your specific project, including whether different colors or sizes can be combined within the order.

When requesting a quotation, ask:

• What is the minimum order quantity for the proposed style?
• Is the MOQ calculated per style, per color or on another basis?
• What is included in the sample and development charges?
• How many sample revisions are included, if any?
• Which materials and product specifications are included in the quoted price?
• What are the estimated production lead time and payment terms?

Avoid comparing quotations based only on the unit price. Two quotes may cover different yarns, finishing details, sampling work or packaging requirements. A clear written quotation makes the comparison more useful.

8. Prepare Your Information Before Requesting a Quote

A well-prepared product brief helps the manufacturer understand your requirements and identify missing details early. You do not necessarily need to have every specification finalized, but you should clearly distinguish confirmed requirements from open questions.

Prepare as much of the following information as possible:

• Product: sweater, cardigan, vest, knitted dress or another garment type
• Design: reference photos, sketches, technical drawings or an existing sample
• Materials: preferred yarn composition, weight or other material requirements
• Measurements: size range, measurement chart and fit preference
• Colors: color references and quantity by color
• Order quantity: estimated pieces by style, color and size
• Branding: labels, hangtags and packaging
• Timing: target sample approval and delivery dates
• Quality: applicable inspection standards and product requirements

If you do not yet have a complete technical pack, explain your product idea and provide clear reference images. Ask the manufacturer to identify which details must be decided before a reliable quotation or sample can be prepared.

9. Protect Your Design and Confirm Responsibilities

Design ownership and permitted use are important considerations in custom knitwear development. The rights associated with a design can depend on the original materials, existing designs, each party's contribution and the written agreement.

Before paying development charges or approving a sample, clarify:

• Which design files and product specifications are supplied by each party?
• Which party owns or may use any newly developed design elements?
• Can the manufacturer offer the same or similar style to other buyers?
• Are any exclusivity arrangements included, and what are their limits?
• How will changes to approved specifications be documented?
• Which sample and specification will be used as the bulk-production reference?

Put important terms in writing rather than relying on assumptions about the meaning of OEM, ODM or private label. If the design is commercially sensitive, consider obtaining appropriate legal advice for your markets and agreements.
