Helping You to Comply

An European Union (EU) based company that manufactures or imports products in the EU is required to register the chemical substances contained in them under REACH.

Under REACH, EU customers of that EU company are classified as 'downstream users'.

Their 'downstream uses' of a substance contained in a given Dow product have to be documented in the registration for that specific substance.

Once a substance has been registered, EU customers must follow the risk management measures, or instructions on uses, specified by the registrant of the substance.

If an EU customer's uses are not documented in the registration for a substance, two options exis

  • The EU customer will pass the necessary information on to the EU company that manufactures or imports the substance. The latter will then modify its registration to include the EU customer's use.
  • The EU customer will have to register its specific use directly with the European Chemicals Agency (ECHA). For this, the EU customer must complete an independent chemical safety assessment for the substance.


MyReach@Dow is a tool that can help Dow Customers in the EU find downstream use information and exposure scenarios as well as REACH product information sheets.
