La principale causa del continuo declino della popolazione del rinoceronte di Giava è stata il bracconaggio per il corno, un problema che affligge tutte le specie di rinoceronte. I corni sono stati oggetto di commercio per più di 2000 anni in Cina, dove si ritiene che abbiano proprietà medicamentose. In epoca storica, la pelle di rinoceronte veniva utilizzata per fabbricare armature per i soldati cinesi, mentre alcune tribù di indigeni del Vietnam credevano che con la pelle si potesse creare un antidoto per il veleno dei serpenti<ref name="AP2">{{cita web|titolo=Scientists Find Surviving Members of Rhino Species|autore=Bruce Stanley|data=22 giugno 1993|sito=Associated Press|url=http://www.apnewsarchive.com/1993/Scientists-Find-Surviving-Members-of-Rhino-Species/id-c348379a851bbead36991c551c6d6b7a}}</ref>. Dal momento che l'areale del rinoceronte si estende su aree estremamente povere, è stato difficile convincere le popolazioni locali a non uccidere un animale apparentemente (almeno a prima vista) inutile dal quale si potrebbero ricavare grosse somme di denaro<ref name="Biotropica"/>. Quando nel 1975 entrò in vigore la [[Convenzione sul commercio internazionale delle specie minacciate di estinzione|Convenzione sul Commercio Internazionale delle Specie Minacciate di Estinzione]], il rinoceronte di Giava fu inserito subito sotto la protezione totale garantita dall'Appendice I; qualsiasi tipo di commercio implicante rinoceronti di Giava o prodotti da essi derivati è illegale<ref name="African">{{cita libro|autore=R.

Le indagini sul prezzo del corno di rinoceronte sul mercato nero hanno determinato che il corno dei rinoceronti asiatici può raggiungere una quotazione di 30.000 $ al chilogrammo, tre volte il prezzo del corno dei rinoceronti africani<ref name="Dinerstein"/>.
The main factor in the continued decline of the Sunda rhinoceros population has been poaching for horns, a problem that affects all rhino species. The horns have been a traded commodity for more than 2,000 years in China, where they are believed to have healing properties. Historically, the rhinoceros' hide was used to make armor for Chinese soldiers, and some local tribes in Vietnam believed the hide could be used to make an antidote for snake venom.<ref name="AP2" /> Because the rhinoceros' range encompasses many areas of poverty, it has been difficult to convince local people not to kill a seemingly (otherwise) useless animal which could be sold for a large sum of money.<ref name="Biotropica" /> When the [[CITES|Convention on International Trade in Endangered Species of Wild Fauna and Flora]] first went into effect in 1975, the Sunda rhinoceros was placed under complete Appendix 1 protection; all international trade in the Sunda rhinoceros and products derived from it is illegal.<ref name="African" /> Surveys of the rhinoceros horn black market have determined that Asian rhinoceros horn fetches a price as high as $30,000 per kg, three times the value of African rhinoceros horn.<ref name="Dinerstein" />{{rp|31}}
 
As with many types Asian and African [[megafauna]], the Sunda rhino was relentlessly hunted by trophy and big-game hunters for decades following the arrival of Europeans in its range. The rhinos being easy targets, this was as severe a contributor to its decline as was poaching for its horns. Such was the toll of [[big game hunting|big-game hunting]] that by the time the rhino's plight was made known to the world, only the Javan and the (then unknown) Vietnamese populations remained.

The Sunda rhinoceros never fared well in captivity. The oldest lived to be 20, about half the age that the rhinos can reach in the wild. No records are known of a captive rhino giving birth. The last captive Sunda rhino died at the [[Adelaide Zoo]] in [[Australia]] in 1907, where the species was so little known that it had been exhibited as an Indian rhinoceros.<ref name="van Strien" />
