CER Codes Guide: How to Properly Classify Special Waste

Correct classification of special waste is a fundamental step for any company that produces, manages, or disposes of waste. CER codes (European Waste Catalogue), now more accurately referred to as EER codes (European Waste List), are the main tool used to identify the type of waste and ensure compliant management.

What CER codes are and what they are used for

CER codes are six-digit numerical codes used to classify waste based on its origin and composition.

Each code identifies a specific type of waste and determines the correct procedures for handling, transport, and disposal.

The code structure follows a precise logic:

  • the first two digits indicate the sector of activity
  • the second two digits identify the production process
  • the last two digits define the specific type of waste

This standardized classification allows uniform waste management across Europe.

How to correctly read a CER code

Correctly interpreting a CER code is essential to avoid classification errors.

Each code must be analyzed considering both its numerical structure and the characteristics of the waste.

For proper classification, it is necessary to:

  • identify the CER chapter related to the production activity
  • determine the process generating the waste
  • select the most specific entry available
  • check for “mirror codes”
  • determine whether the waste is hazardous or non-hazardous

A thorough analysis ensures accurate and compliant classification.

Hazardous vs non-hazardous waste: key differences

A fundamental distinction is between hazardous and non-hazardous waste, which directly affects management procedures.

Hazardous wastes are identified by an asterisk (*) next to the CER code and includes substances that may pose risks to health or the environment.

The main differences include:

  • stricter requirements for transport and disposal
  • specific packaging and labeling obligations
  • more rigorous controls by authorities
  • stricter traceability

Correct classification is essential to avoid legal liabilities.

Company responsibilities in waste classification

The responsibility for correctly assigning the CER code always lies with the waste producer. This means that the company must ensure that each waste stream is accurately identified and documented.

Specifically, the company must:

  • assign the correct CER code
  • maintain waste traceability
  • properly complete waste documentation (FIR forms)
  • retain records and documentation
  • rely on authorized operators

Incorrect classification may lead to administrative and criminal penalties.

Common mistakes to avoid

Waste classification is a technical process that requires attention. Some mistakes can compromise the entire waste management workflow.

The most common errors include:

  • choosing generic codes instead of specific ones
  • failing to verify mirror codes
  • incorrect hazard assessment
  • missing chemical analysis when required
  • using outdated codes

Avoiding these mistakes is essential to ensure regulatory compliance.

Regulatory framework

Waste classification using CER codes is governed by European and national regulations, which define criteria and responsibilities for waste management.

The main reference in Italy is Legislative Decree 152/2006 (Environmental Consolidated Act), which establishes obligations for waste producers and operators, alongside EU decisions that periodically update the CER list.

Compliance ensures safe operations, avoids penalties, and guarantees proper waste management.

FAQ

They are six-digit codes used to identify waste types.

There is no substantial difference: CER (European Waste Catalogue) and EER (European Waste List) refer to the same 6-digit classification system.

The waste producer is responsible for classification.

By the * symbol next to the CER code.

Similar codes used to distinguish hazardous and non-hazardous waste.

Yes, when necessary to determine hazardous properties.

It may lead to legal liabilities and financial penalties.
