They amend the Infant Formula and Follow-on Formula Regulations 1995 (SI 1995/77) which implemented inter alia Commission Directive 91/321/EEC on infant formulae and follow-on formulae, so as to take account of amendments made to that Directive by Commission Directive 96/4/EC. The Regulations contain a transitional provision which provides that it is not an offence, before 31 March 1999, to sell or export infant formulae or follow-on formulae which do not comply with 1995/77 as amended but which do comply with their provisions before amendment.
