Muna 1905, UL yakatanga Label Service yevamwe zvigadzirwa zvigadzirwa zvinoda kakawanda kuongororwa. Vanoongorora veL vakaitisa yekutanga fekitori kuongororwa zvigadzirwa pazvivakwa zvevagadziri- maitiro chinoramba chiri chinosarudzika cheLU yekuedza uye retifiketi chirongwa.

UL yakawedzera kuita sangano rine makumi matanhatu nematanhatu maLabhoritari, kuyedza uye zvitupa zvinoshandira vatengi munyika 64 Yakave zvakare yakachinjika kubva pamidzi yayo mukuchengetedza kwemagetsi nemoto kugadzirisa zvinhu zvakakura zvekuchengetedza, senge zvinhu zvine njodzi, mhando yemvura, chengetedzo yechikafu, kuyedzwa kwekuita, kuchengetedzeka uye dzidzo yekuteerera pamwe nekusimudzira kwezvakatipoteredza.

Muna 2012, UL yakashandurwa kubva kune iyo isiri purofiti kambani kuita yekudyara mubatanidzwa.
