How Does Contract Manufacturing of Food Supplements Work? Clients’ Most Frequently Asked Questions

What Does Working with a Contract Manufacturer of Food Supplements Involve?

Contract manufacturing of food supplements is a cooperation model that allows a company to launch a product under its own brand without having its own production line. The entire manufacturing process is outsourced to an experienced contract manufacturer with the required technology and production facilities.

This eliminates the need to invest in a manufacturing plant, machinery or personnel. Contract manufacturing primarily reduces costs and the risks associated with establishing in-house production, while also enabling a faster market launch. In addition, the client benefits from the expertise of an established manufacturing partner.

Stages of Contract Manufacturing of Food Supplements

1. Concept development and consultation with the contract manufacturer. The client selects a white-label product from the contract manufacturer’s existing range or presents their own product idea, formulation and requirements under a private-label model. The intended purpose and planned batch size are also determined at this stage.

2. Food supplement formulation development. The manufacturer helps develop the formulation and manufacturing process appropriate for the selected product format, such as a shot, syrup, powder, drops or capsules.

3. Preliminary product quotation. The client receives an initial quotation that allows them to assess the costs, required investment and pricing strategy.

4. Prototype preparation and approval. The client works with the contract manufacturer to refine the prototype’s formulation and organoleptic properties. Once approved, the prototype becomes the reference sample for future production batches.

5. Testing and quality control. The completed prototype undergoes quality and stability testing to ensure product safety.

6. Preparing the finished product documentation. This is the final stage of the research and development process, culminating in the delivery of the Product Specification to the client.

7. Full-scale production of food supplements. The product is manufactured on a commercial scale in accordance with applicable quality standards, including GMP, HACCP and ISO 22000.

8. Packaging, labelling and final packing. The finished product is packaged in accordance with the client’s vision and all applicable regulations.

Product Documentation – What Does the Client Receive from the Contract Manufacturer?

Once the client has approved the product prototype, the contract manufacturer provides a Food Supplement Product Specification. This document contains key information about the product the client intends to commission for full-scale production.

The Product Specification as a Formal Commitment to Quality and Safety

The contract manufacturer is required to manufacture the product in accordance with the information contained in the specification. A Product Specification typically includes:

• product description;

• organoleptic properties, including form, colour and taste;

• product composition and a list of ingredients;

• active ingredient content, including the exact quantity per serving;

• recommended daily intake;

• physicochemical parameters;

• microbiological parameters;

• packaging description;

• storage conditions;

• transport conditions;

• shelf life.

If the contract manufacturer supplies a product that does not comply with the specification, the client may use the document as the basis for lodging a complaint.

Packaging Design and Intellectual Property Rights

The specification also contains essential information that must appear on the client’s packaging. In addition to marketing content, the packaging designer should incorporate the relevant information provided in the specification.

The Product Specification as Intellectual Property

Depending on the individual agreement with the contract manufacturer, the client may also acquire the rights to the product. In such cases, the contract manufacturer transfers the relevant intellectual property rights. The Product Specification and Manufacturing Process Specification, which describes how the product is made, provide the basis for verifying the scope of those rights.

What Basic Legal Requirements Apply to the Contract Manufacturing and Sale of Food Supplements and Functional Foods?

Developing a Compliant Formulation and Dosage

Polish and EU legislation regulates the composition, dosage and intended use of food supplements and functional foods. An experienced contract manufacturer supports its partners with regulatory matters, helping them avoid unnecessary mistakes from the outset. In complex cases, Hemplab can assist in selecting a legal adviser specialising in food law.

Notification of a Food Supplement to GIS

As the entity responsible for placing a food supplement or functional food on the market, the client must notify Poland’s Chief Sanitary Inspectorate (GIS) of their intention to do so. Through the online portal administered by GIS, the client submits the product’s name and the information displayed on its packaging. Hemplab assists with preparing and submitting the notification. Once the notification has been submitted, the product may be sold to consumers.

Obligations of the Contract Manufacturer and Brand Owner Arising from Official Food Production Supervision

Every food manufacturer—including Hemplab as a manufacturer of food supplements and functional foods—must meet quality requirements and implement appropriate production quality and safety standards to manufacture food legally.

Compliance is confirmed by entering the manufacturing facility in the register of establishments subject to official supervision by the State Sanitary Inspectorate. Before registration, inspectors from the relevant local sanitary authority visit the facility to verify that the declared quality standards are being maintained. This inspection covers both the infrastructure and operating procedures.

If only some stages of contract manufacturing are outsourced to the contract manufacturer while the client handles other stages independently, such as labelling, the client may also be required to register their operations with the relevant sanitary authority.

Basic Scope of the Contract Manufacturer’s Responsibility

The contract manufacturer is primarily responsible for the quality and safety of the manufactured product. In practice, this means ensuring that the product complies with its specification and the individual arrangements agreed with the client.

The Product Specification defines the applicable quality and safety requirements, including the product’s composition, appearance, taste, aroma and freedom from various contaminants. Individual arrangements may impose additional obligations on the manufacturer, such as using raw materials of a specified origin, applying customised packaging or labelling methods, storing client-supplied materials or allowing audits of the manufacturing facility.

The scope of cooperation depends primarily on the initiative and flexibility of both parties. Hemplab adapts its cooperation model to the client’s expectations and business model.

Brand Owner’s Responsibility for Product Quality and Safety

Despite working with a contract manufacturer, the owner of a food supplement or functional food brand retains a number of obligations. The entity responsible for selling products to consumers is primarily accountable for their quality and safety.

Liability may be transferred to the contract manufacturer—for example, if the manufacturer is responsible for a product defect. However, consumers will generally direct any claims to the entity that placed the product on the market. Appropriate contractual provisions can protect the brand owner against liability for the contract manufacturer’s errors. Nevertheless, choosing the right manufacturer remains crucial, as any such issue may damage the brand’s reputation.

Responsibility for Marketing Communications

The brand owner is fully responsible for its marketing activities, over which the contract manufacturer has no control. Polish and EU regulations govern how food supplements and functional foods may be advertised. Any errors in this area will be the responsibility of the entity placing the product on the market. If there is any uncertainty, we recommend consulting a legal adviser specialising in food supplement advertising.

Contract Manufacturer’s Quality Standards

To demonstrate high standards of production quality and safety, food manufacturers implement quality management standards and obtain certification from independent certification bodies. Certifications such as ISO 22000, IFS and BRC relate to different sets of food production quality requirements and provide evidence that a particular manufacturer maintains the relevant standards.

Specific production regimes may also be certified, including organic or HALAL production.

Ask your contract manufacturer which certifications they hold. Implementing and maintaining such standards enhances the security of your brand and can add value to your product.

Working with a Contract Manufacturer – What Can the Client Expect?

Working with a contract manufacturer involves more than simply placing an order. A reliable partner provides transparent communication at every stage of the project and helps clients make informed technological and business decisions.

Clients can expect practical expert support, guidance on manufacturing and regulatory requirements, and a collaborative approach based on a clear understanding of the brand’s objectives. This type of partnership not only enables an efficient product launch but also supports the development of a stable, long-term business.
