CAS No.: The identification number assigned to a substance in the Chemical Abstract Service.

Company responsible for declaration: The company responsible for submitting the declaration to the Norwegian authorities.

Declaration number (P number): An unambiguous identification number that is established in connection with declaration to the Product Register. A declaration number is a specific link between a company and a chemical product. A declaration number is not an approval of the chemical.

EC No.: The identification number for the substance in the EEA area. The EC number for the substance can be found in EINECS or ELINCS (

Export: In this guide, export is a generic term for all export from Norway. This means that no distinction is made between export to countries within/outside the EEA area.

Hazard label: In this context, labelling is limited to hazard codes and hazard statements under the Chemical Labelling Regulations or signal words, codes for pictograms and codes for hazard statements under the Norwegian CLP Regulations.

Hazardous chemicals: Chemical substances and mixtures that may entail health, environmental, fire and explosion hazards.

Identification number: In these guidelines, identification number (ID number) is defined as the CAS number, EC number or the Product Register's declaration number.

Importer: In these guidelines, importer is defined as any physical or legal person that is the first party in Norway to introduce the chemical. This means that no distinction is made between import from countries within/outside the EEA area. The companies must have a Norwegian address, and be registered in the Brønnøysund Registers.

Quantity imported: Quantity (in tonnes) of the chemical that the company responsible for declaration imports into Norway every year. No distinction is made between import from countries within/outside the EEA area.

Chemical products: In these guidelines, chemicals and chemical products are identical terms. These guidelines defines chemical products and chemicals as an a generic term for substances and mixtures.

Chemical substance: A chemical element and its compounds as they occur naturally or through industrial manufacture. This includes any additives necessary to preserve the substance's stability and any impurities deriving from the manufacturing process used, excluding any solvent which can be separated without affecting the stability of the substance or changing its composition.

Classification: Placement of a substance in hazard classes or hazard categories, pursuant to the Chemical Labelling Regulations and/or the Norwegian CLP Regulations. Classification of each constituent of a chemical product provides the foundation for the hazard labelling.

Constituents: An generic term for substances and raw materials in the composition of a chemical product.

Customer: The Norwegian company/companies that are the first recipients in Norway when foreign companies submit a declaration form.

Microbiological products: Raw material, excipient, intermediate product or finished product of any kind which consists of or contains microorganisms for specific applications, including sanitary cleaning, deodorization, cleansing drains, grease control and cleaning up oil spills and contaminated sites. The product can also contain other substances such as surfactants, deodorizing agents, enzymes, mineral nutrients, salts or other chemicals.

Name change: If a chemical is bought in Norway and resold under a different commercial name or resold with the same commercial name but under a new label, an independent declaration must be submitted. The quantity must be listed under "name change" through annual reporting of quantities.

Polymer: A substance consisting of molecules characterised by the sequence of one or more types of monomer units. Such molecules must be distributed over a range of molecular weights wherein differences in the molecular weight are primarily attributable to differences in the number of monomer units. A polymer comprises the following:

a) a simple weight majority of molecules containing at least three monomer units which are covalently bound to at least one other monomer unit or other reactant.

b) less than a simple weight majority of molecules with the same molecular weight. In this definition a 'monomer unit' means the reacted form of a monomer substance in a polymer.

Product type: Specification of the chemical product's function defined with the UCN code set.

Manufacturer: The company that manufactures the chemical product to be declared.

Raw materials: Chemical products with a commercial name and own declaration number that are constituents of another chemical. Raw materials must be declared separately.

Mixtures: Solutions or solid, liquid or gaseous mixtures that are composed of two or more chemical substances.
