The economy of Haiti is a free market economy with low labor costs. Haitis major trading partner is the United States (US), which provides the country with preferential trade access to the US market through the Haiti Hemispheric Opportunity through Partnership Encouragement (HOPE) and the Haiti Economic Lift Program Encouragement Acts (HELP) legislation.Haiti has an agricultural economy. Over half of the worlds vetiver oil (an essential oil used in high-end perfumes) comes from Haiti, and bananas, cocoa, and mangoes are important export crops. Haiti has also moved to expand to higher-end manufacturing, producing Android-based tablets  and current sensors and transformers.Vulnerability to natural disasters, as well as poverty and limited access to education are among Haitis most serious disadvantages. Two-fifths of all Haitians depend on the agriculture sector, mainly small-scale subsistence farming, and remain vulnerable to damage from frequent natural disasters, exacerbated by the countrys widespread deforestation. Haiti suffers from a severe trade deficit, which it is working to address by moving into higher-end manufacturing and more value-added products in the agriculture sector. Remittances are the primary source of foreign exchange, equaling nearly 20% of GDP. Haitis economy was severely impacted by the 2010 Haiti earthquake which occurred on 12 January 2010.
