What is RoHS? Meaning, Requirements and Compliance Explained

Introduction

Electrical as well as electronic products may contain hazardous substances that can affect human health and the environment if they are not properly controlled. RoHS (Restriction of Hazardous Substances) helps address this concern by limiting the use of specified substances in notified electronic equipment. For manufacturers, importers, as well as exporters, understanding RoHS requirements is absolutely essential for market access and product compliance. 

This blog explains RoHS meaning, restricted substances, compliance requirements, and India's CPCB-related self-declaration requirements under the E-Waste (Management) Rules, 2022.

What is RoHS and Why Does It Matter for Businesses?

Imagine a company that is importing electronic accessories into India. Its products meet the required electrical safety standards, and the business has completed the necessary product registration. However, the supplier cannot confirm whether the materials that have been used in the products contain restricted hazardous substances within the permitted limits.

This creates a separate compliance concern.

A product may meet electrical safety requirements but still require a review of its chemical composition under applicable RoHS regulations.

RoHS basically addresses this issue by restricting certain hazardous substances that are used in electrical and electronic equipment. These substances may be present in solder, circuit boards, cables, plastic housings, connectors, coatings, as well as various other components. The objective is mainly to reduce hazardous substances in products and support safer handling as well as recycling when electronic equipment reaches the end of its useful life.

For businesses, RoHS compliance can help with the following considerations:

• Meeting environmental requirements in the target market.
• Demonstrating that products meet applicable substance restrictions.
• Improving communication with suppliers and component manufacturers.
• Supporting product documentation and compliance audits.
• Reducing the risk of rejected shipments or corrective action due to non-compliant materials.
• Meeting customer and distributor requirements for restricted substances.

RoHS is therefore not just a requirement for large electronics manufacturers. It can also matter to importers, private-label brands, component suppliers, as well as businesses that are selling electronic products in international markets.

What Does RoHS Stand For?

RoHS stands for Restriction of Hazardous Substances.

The term is commonly associated with the European Union's Directive 2011/65/EU, which restricts certain hazardous substances in electrical and electronic equipment. The directive is often called the RoHS Directive or EU RoHS.

For example, a manufacturer that is exporting electronic equipment to Europe may need to check RoHS compliance alongside other applicable EU product requirements. A company that is selling electronic equipment in India may also need to consider the country's E-Waste (Management) Rules, 2022, where applicable.

Which Substances Are Restricted Under RoHS?

The EU RoHS framework usually restricts ten substances. These include heavy metals, flame retardants, as well as plasticisers that may be used in electrical and electronic products.

It is important to note that the presence of a substance does not automatically mean that a product violates RoHS. The concentration in the relevant homogeneous material, the product category, and any applicable exemption must be considered.

For most restricted substances under EU RoHS, the maximum concentration is 0.1% by weight in each homogeneous material. A homogeneous material is a material that cannot be mechanically separated into different materials. For example, the plastic insulation on a cable and the metal conductor inside it are checked as different materials.

How Does RoHS Compliance Work in Practice?

RoHS compliance usually requires a business to understand what its product contains and demonstrate that restricted substances remain within the applicable limits. It is not enough to obtain a general statement from a supplier who may be saying that a product is environmentally friendly. The business should have suitable evidence to support its compliance claims.

A practical RoHS compliance process involves the following steps.

• Step 1: Identify the Applicable Regulation

  First, the applicant must determine where the product will be sold. Businesses must not assume that compliance with one country's RoHS requirements automatically establishes compliance with another country's rules.

• Step 2: Prepare a Product and Component List

  Identify the materials as well as the components that are used in the product. It helps businesses identify which suppliers must provide information about restricted substances.

• Step 3: Collect Supplier Declarations

  Request material declarations, component specifications, as well as relevant RoHS compliance statements from suppliers.

• Step 4: Assess the Technical Evidence

  Review the available technical documentation in order to determine whether it supports compliance with the applicable substance restrictions. Where the available information is incomplete or raises concerns, additional testing may be necessary for compliance.

• Step 5: Arrange Testing When Required

  Laboratory testing can help establish the concentration of restricted substances in selected materials. A risk-based approach may help prioritise components more likely to contain restricted substances. However, the sampling and evaluation method must be suitable for the product as well as the applicable requirements.

• Step 6: Maintain the Compliance File

  Keep the relevant declarations, material information, test reports, and product identification records together to prevent last-minute hassles.

RoHS Requirements in India: What Should Manufacturers and Importers Know?

RoHS-related compliance in India is basically connected to the E-Waste (Management) Rules, 2022, which came into force on 1 April 2023. Rule 16 of the same addresses the reduction of hazardous substances in specified electrical and electronic equipment and its components, consumables, parts, as well as spares.

The rules establish concentration limits for six substances: lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE.

The prescribed limits are as follows:

• 0.1% by weight in homogeneous materials for lead, mercury, hexavalent chromium, PBB, and PBDE.
• 0.01% by weight in homogeneous materials for cadmium.

The rules also provide for specified exemptions and special conditions. Businesses should therefore verify the applicable product category, amendments, and exemption provisions before making a compliance declaration in order to ensure compliance.

What is the Role of CPCB in RoHS Compliance?

The Central Pollution Control Board (CPCB) plays an important role in implementing India's E-Waste (Management) Rules, 2022. Under the same, applicable producers must meet the prescribed hazardous-substance requirements. Rule 16 also requires producers to provide information on compliance through self-declaration.

For businesses, this means that RoHS compliance is not simply a matter of stating that a product contains no hazardous substances. The declaration must relate to the applicable requirements, and the supporting technical records should be maintained.

Is RoHS Self-Declaration Required for Indian Producers?

Yes, it is required for producers who are covered by the applicable provisions. The relevant requirements include the following:

• Ensuring that covered equipment meets the applicable concentration limits.
• Providing the prescribed declaration of compliance.
• Providing information about the constituents of the equipment and its components in the product user documentation, as required under Rule 16.
• Maintaining technical documentation in order to support compliance.
• Making the required information available for regulatory verification.

CPCB describes the RoHS self-declaration and supporting technical documentation declaration mainly associated with EPR registration. 

Note: A RoHS self-declaration is not the same as an independent laboratory test report. It is a declaration made by the responsible business under the applicable regulatory framework. The RoHS declaration does not replace mandatory Indian market compliances like EPR registration or other applicable approvals.

RoHS vs CPCB EPR Registration

These terms are sometimes used together in product-compliance discussions, but businesses must understand that they serve absolutely different purposes.

A business may need to address more than one of these requirements for the same product.

For example, an importer of a covered electronic product may need to check whether the product requires CPCB EPR registration, and whether the product meets the applicable hazardous-substance restrictions.

These assessments should be conducted separately because the scope, documents, as well as legal obligations are completely different.

Which Products May Need RoHS Compliance?

RoHS requirements can apply to a wide range of electrical and electronic equipment, generally depending on the applicable regulation and product category:

• Consumer electronics: Televisions, audio equipment, digital cameras, and electronic accessories.
• IT equipment: Computers, laptops, keyboards, printers, and computer peripherals.
• Communication equipment: Certain communication devices and electronic networking products.
• Lighting equipment: Covered LED lighting products and other applicable electrical lighting equipment.
• Electrical components: Cables, connectors, circuit boards, and electronic assemblies incorporated into covered products.
• Household appliances: Applicable electrical appliances and electronic controls.
• Industrial electronics: Equipment falling within the relevant regulatory scope.

Before importing or manufacturing a product, businesses should confirm its classification under the relevant rules rather than relying solely on its commercial name.

What Happens If a Product Does Not Meet RoHS Requirements?

Non-compliance with RoHS parameters can often create problems beyond the immediate cost of replacing a component. A business may face regulatory scrutiny, corrective-action requirements, restrictions on placing the product on the market, or other enforcement measures.

In India, Rule 16 of the E-Waste (Management) Rules, 2022, includes provisions for addressing non-compliant equipment. Producers should take the required corrective measures and follow applicable procedures if a product fails to meet the hazardous-substance requirements.

Common business risks include:

• Delays in launching a product.
• Additional laboratory testing and component replacement costs.
• Disputes with suppliers over non-compliant materials.
• Problems responding to customer or regulatory requests.
• Corrective action affecting products already placed on the market.

The most effective way to reduce these risks is to establish a compliance process before a product enters the market.

RoHS Compliance Checklist for Manufacturers and Importers

Before selling or importing an electrical or electronic product in the market, use this checklist to organise your RoHS compliance work:

• Identify the countries where the product will be sold.
• Confirm whether the product falls within the applicable RoHS framework.
• Identify the restricted substances and concentration limits.
• Review the product's materials and components.
• Obtain relevant supplier declarations as well as technical documents.
• Arrange laboratory testing where necessary.
• Check whether a specific exemption applies.
• Prepare the required self-declaration for Indian compliance.
• Maintain technical records for verification purposes.
• Review the documentation whenever the product or its components change.
• Separately evaluate applicable BIS certification and CPCB EPR registration requirements.

This approach mainly helps businesses to smoothly connect their technical product information with the regulatory requirements that apply to their operations.

Conclusion

RoHS compliance is an important consideration for businesses that are manufacturing, importing, or exporting electrical and electronic equipment. It helps establish whether covered products meet the applicable restrictions on hazardous substances. The important step is to determine which rules apply to the product, obtain reliable technical evidence, and maintain the documentation that is needed to support compliance.
