We purchase hazardous substances from within the EU, and re-brand them for sale as our products. I administer the Safety Data Sheets and effectively just re-brand the supplier's SDS adding our contact details and logo. Under REACH annex II, and in fact before, there is a requirement to identify the person responsible for placing the substance on the market including and email and telephone number. This person must be "competent". I am not competent to answer detailed chemical questions beyound what is on the SDS. Marketing would be unhappy to leave reference to our supplier on the SDS. Do we have a straight choice - employ a chemist or leave the supplier's SDS as it is with our product name added? Any ideas?

I don't think you can legally usurp the role of the person placing the product on the market.
