Industry

Industry contributes a large portion of Karachi's economy, with the city home to several of Pakistan's largest companies dealing in textiles, cement, steel, heavy machinery, chemicals, and food products. The city is home to approximately 30 percent of Pakistan's manufacturing sector, and produces approximately 42 percent of Pakistan's value added in large scale manufacturing. At least 4500 industrial units form Karachi's formal industrial economy. Karachi's informal manufacturing sector employs far more people than the formal sector, though proxy data suggest that the capital employed and value-added from such informal enterprises is far smaller than that of formal sector enterprises. An estimated 63% of the Karachi's workforce is employed in trade and manufacturing.

Karachi Export Processing Zone, SITE, Korangi, Northern Bypass Industrial Zone, Bin Qasim and North Karachi serve as large industrial estates in Karachi. The Karachi Expo Centre also complements Karachi's industrial economy by hosting regional and international exhibitions.
