Material compliance and product approval

For a product to be placed on the market safely and in compliance with regulations, different legal, technical and customer-specific requirements must be met depending on the application. Material compliance, product compliance, conformity assessment and product approval play a central role here.

Particularly with engineering plastics, it is not enough to consider only the mechanical or thermal properties of a material. Specifications regarding ingredients, food contact, electrical safety, biocompatibility or traceability can also influence the selection of suitable materials.

Which requirements actually apply depends on the product, its intended use, the target market and the respective industry. For applications in medical technology, the food industry or the electrical industry, different sets of rules and evidence may therefore be required.

The following explains what material and product compliance mean, how a conformity assessment is carried out and which steps must be observed on the way to product approval.

What does product compliance mean?

Product compliance means that a product meets the requirements applicable to its intended use. These requirements may arise, for example, from laws, EU regulations and directives, technical standards or binding customer specifications.

Which requirements are placed on a product therefore cannot be answered across the board. First, the intended purpose, the market and the product-specific regulations must be determined.

Typical areas of a product compliance check are:

• materials and ingredients used,
• technical and mechanical properties,
• electrical or functional safety,
• chemical resistance,
• fire behaviour,
• hygiene or food requirements,
• biocompatibility,
• labelling and traceability,
• technical documentation,
• required test and conformity evidence.

Product compliance therefore relates to the finished product and goes beyond the mere assessment of the material used.

Which requirements apply to products?

Approvals and regulations are the legal and technical guard rails of every industrial product development. They define which materials, processes and evidence are required to place a product on the market. This is not just about formalities, but about safety, environmental compatibility and traceability in all production steps. Legal regulations such as REACH, RoHS, CLP, MDR or EU 10/2011 define the chemical and mechanical requirements for materials. These regulations ensure that hazardous substances are reduced, work processes are made safer and environmental impacts are minimised.

Companies are also expected to demonstrate a consistent risk management system and a functioning quality management system. International standards such as DIN, EN, ISO, ASTM or UL and customer-specific requirements create additional transparency and trust. The aim of all these sets of rules is that a product not only functions technically, but is also manufactured safely, reproducibly and sustainably.

In a globalised supply chain, compliance with these regulations is becoming increasingly complex, especially when components are manufactured or distributed in different countries. Close collaboration between development, purchasing, quality assurance and external partners is crucial here.

From idea to material: The phase of material compliance

Material compliance describes whether a material meets the substance-related, regulatory and technical requirements relevant to its intended use. It is particularly important when there are specifications for the later product regarding ingredients, food contact, electrical properties, biocompatibility or other regulated properties.

Already during material selection, it should therefore be clarified which requirements the later component must meet. In addition to regulatory specifications, properties such as temperature resistance, chemical resistance, mechanical load capacity and processability must also be taken into account.

Steps to material compliance

1. Define the intended use

First, the conditions under which the material is to be used are determined. These include, for example, temperature, mechanical load, contact with chemicals and special requirements from food, medical or electrical applications.

2. Determine relevant requirements

In the next step, it is checked which legal specifications, standards and customer specifications are relevant for the material and application.

3. Assess material and material data

Technical data sheets, manufacturer information, substance information and available declarations of conformity are compared with the requirement profile.

4. Define required tests

If existing documents are not sufficient for the intended use, additional chemical, thermal, mechanical or application-specific tests may be required.

5. Document evidence

The relevant material information, test reports, manufacturer declarations and other evidence should be documented in a traceable manner and assigned to the respective material or component.

6. Monitor changes

If material formulations, suppliers, regulatory requirements or the intended purpose change, material compliance should be reassessed.

Example standards for material compliance

Area	Relevant standards/regulations	Typical evidence
Food contact	EU 10/2011, FDA CFR 21	Migration testing, material declaration
Drinking water	KTW, W270, DVGW	microbiological and chemical tests
Electrical industry	RoHS, REACH	substance list, supplier declaration
Medical technology	MDR, ISO 10993	biocompatibility, sterilisation testing

A common misconception: material compliance does not replace product approval. It is merely the prerequisite for it.

Product approval: From material to marketable component

Once the material has been tested, the assessment of the finished product follows. The focus here is on the entirety of the technical, safety-relevant and documentary requirements. Every product approval is a structured process that ranges from prototype testing to series release.

Safety tests ensure that the product functions reliably under real operating conditions. Environmental tests test the plastic's resistance to UV radiation, ozone or temperature cycles. Electromagnetic compatibility, electrical safety and durability are also checked.

At the same time, extensive technical dossiers, test evidence and risk assessments must be created to ensure seamless traceability. Only after release by internal quality systems and – where required – external certification bodies may the product be officially placed on the market. This process not only ensures compliance with legal regulations, but also protects the manufacturer's reputation, liability and ability to deliver. Companies that act with foresight here reduce later adaptation costs and strengthen their market position in the long term.

Practical example: Sealing system in the food industry

A manufacturer develops a new elastomer sealing system for milk processing plants. Already in the design phase, an analysis is carried out to determine which standards apply: EU 1935/2004, FDA 21 CFR 177.2600 and ISO 9001. After material release, leak-tightness, cleaning and temperature tests are carried out. Only after an independent audit by TÜV is approval granted. The product may now be marketed with CE marking and a declaration of conformity.

Role of standards and specifications in the global market

Standards are the backbone of international trade relations. They create uniform assessment bases for quality, safety and environmental compatibility and make it possible for products to be comparable and interchangeable across national borders. In industries such as mechanical engineering, chemicals, electronics or medical technology, international standards are a prerequisite for market access. At the same time, standards promote innovation, as they structure development processes and standardise test procedures.

Standard-compliant product design also gives companies access to new markets, facilitates audits and minimises liability risks. However, because the standards landscape is constantly evolving, companies must actively work to regularly adapt their internal processes, test specifications and supplier assessments. Structured standards management thus becomes a decisive competitive factor.

Digitalisation and automated compliance

Digitalisation is changing the way companies fulfil their regulatory obligations. Modern compliance management systems are no longer just digital repositories, but intelligent control centres that evaluate and link data, test reports and certificates. AI-supported platforms can automatically detect when new legal requirements arise or substance bans come into force, and suggest appropriate measures. This not only increases efficiency, but also legal certainty.

Companies that digitalise their compliance data benefit from significantly better traceability along the entire supply chain. Automated interfaces to suppliers and testing laboratories enable the direct exchange of test certificates and updated safety data sheets. The result is a transparent, audit-proof system that can provide robust evidence immediately in the event of an audit. In the long term, this development will evolve into a complete digital representation of all compliance processes – from material release to end of product life.

Sustainability and ecological responsibility

Approvals and regulations increasingly take ecological criteria into account. In addition to technical safety, aspects such as recyclability of plastics, CO₂ balance and life cycle assessment are moving to the fore. Companies must demonstrate that their materials are produced in an environmentally friendly way, are recyclable or even biodegradable. In the plastics industry, bio-based materials are gaining in importance.

They make it possible to meet legal requirements while at the same time contributing to resource conservation. Approval authorities increasingly check whether these materials are ecologically sound and safe throughout their entire life cycle – from raw material extraction through processing to recycling. Sustainability of plastics is therefore no longer an optional criterion, but part of product assessment and market approval.

Risks of non-compliance

Ignoring approvals and regulations can have serious consequences. Typical risks are:

• Fines and market bans: Violations of legal requirements lead to high penalties and can prevent the distribution of products.
• Recalls: Non-compliant components often have to be fully recalled – with considerable costs and reputational damage.
• Liability claims: Manufacturers are liable for damage caused by unapproved or defective products.
• Production stoppages: Missing approvals can block entire production lines until evidence is provided.
• Loss of certifications: Inadequate documentation or missing audits can lead to the withdrawal of important certificates (e.g. ISO 9001, IATF 16949).
• Reputational damage: Trust from customers, partners and authorities is lost in the long term.
• Supply chain problems: A single non-compliant material can jeopardise international production networks.

Early and structured compliance management is therefore essential. It ensures that all specifications along the entire value chain are met and protects the company from financial and legal risks.

Future prospects: Intelligent approval systems

The future of product approval lies in digitally networked testing procedures and intelligent approval systems. In future, AI models will not only simulate material properties, but also be able to predict potential risks and ageing effects. This allows more precise planning of product life cycles and maintenance intervals. In combination with real-time data from production and use, dynamic, adaptive approval systems are emerging that update themselves automatically when legal requirements change.

Digital "product passports" are conceivable, containing all material data, recycling rates and conformity evidence and updated throughout the entire life cycle. The EU is driving this development forward with the Digital Product Passport Initiative – a further step towards a fully transparent, sustainable and digitally controlled industry.

Safety, trust and capacity for innovation

Material compliance and product approval are not obstacles, but essential drivers of quality, innovation and competitiveness. They form the foundation of modern industrial development by creating legal certainty and promoting sustainable production processes. Companies that understand these requirements not as an obligation but as a strategic advantage benefit twice over: they avoid risks and at the same time strengthen their brand trust.

Well-considered approval management makes it possible to bring products to market faster, minimise liability risks and comply with international standards efficiently. Approvals and regulations are therefore not the end of creativity – they are the framework that makes technical innovation responsible and marketable.
