US companies that donot have a legal presence in the European Union donot have any direct obligations under REACH, regardless of whether or not they sell products into the EU.
However, REACH may have an impact on supply. The costs associated with registration or potential restrictions may lead EU manufacturers to phase out certain substances. Therefore US companies may witness supply difficulties for some products and raw materials.
It is also likely that products, where purchased from the EU, will become more expensive as REACH is implemented.
Any US company with a presence in the EU may well be affected by the REACH requirement that importers, manufacturers, producers and downstream users comply with various procedures including, in some cases, registration of substances.
