Other key lawyers:

‘The team successfully completed several tasks for the contractual structuring of our company. We couldn’t have asked for a better partner and they were overall competitively priced.’

‘Brilliant professionals. The support provided by Peter Sellar was excellent and superb.’

‘Claudio Mereu and his team have been assisting us for more than 10 years; strong capability to directly comumunicate (they avoid the typical “lawyer’s language” distant from the industry business and regulatory environment) with industry based on excellent knowledge of business; their excellent knowledge of the Italian language is highly appreciated by our clients!’

‘Excellent knowledge and skills in multiple chemical regulatory sectors; very successful performance and high success rates; straight forward approach versus realistic and achievable goals; strong positive reputation at all levels like industry, national and European regulatory authorities, ECHA, EU COMM and many others.’

‘Exceptional depth in REACH and chemical regulatory law and procedure.’

‘Claudio Mereu is widely regarded as a top chemical regulatory lawyer in Brussels. His depth of knowledge and experience in REACH is encyclopedic. Yet he is accessible and gives practical advice.’

‘The FF team is extremely specialised in the review of chemical issues. It is a sector which is very technical and requires a strong understanding of scientific evaluations. It is not something that can easily be mastered. You need years of expertise. In this sense, once you have a deep expertise of the chemical industry, it is impossible to match.’

‘Claudio Mereu as MD is supervising all clients/files and gives the strategic direction. He has been in this chemical sector for 25 years. He is well recognised by all clients and all know one another. Claudio has experience in pesticides, REACH & biocides like no other lawyers in Brussels. Simon Englebert is the number 2 in the team and fulfils perfectly his role, having been working many years on these dossiers. The other team members are also very useful. Fees are fine and within market range, follow-up is excellent.’
