The Ninoy Aquino International Airport (NAIA) was established by virtue of CAO No. 2149 promulgated on September 16, 1960, creating an independent customs house at the former Manila International Airport.

Through constant improvements in organization, facilities and operations, the NAIA has emerged as a domestic showcase of trends in international trade, commerce and tourism. At the 93rd founding anniversary of the Bureau in 1995, the district inaugurated a four-storey customs house.

As the country’s premier airport and gateway, NAIA’s collection performance is often a barometer of the national economy.

As a customs port of entry for foreign trade, it is relatively new. It was organized as such on August 7, 1948 following the enactment of R.A. No. 284 on June 16, 1948. The District Port of San Fernando is comprised of the provinces of Ilocos Sur, Mountain Province. La Union, Nueva Vizcaya and Pangasinan and all the islands within its jurisdiction.

San Fernando existed as a national port of coastwise trade under the Manila Collection District from 1902 to March 1917. When Act No. 2681 was enacted by the Philippine Commission, it became part of the Pangasinan and La Union with Sual as principal port of entry.

In 1972, a re-organization plan made San Fernando a principal port of entry with Aparri, Claveria, Gaang and Sual as subports. In 1982, the Laoag International Airport also became a subport, along with EPZA-Baguio City in 1984 and Salomague in 1996.

San Fernando has consistently ranked as one of the top 10 ports in terms of revenues and collections. Its importance arises from being an outlet for the country’s mine products such as copper concentrate and as the port of entry for fertilizers, imported coal, gypsum, slag (raw materials for cement manufacturing), various machineries and general cargo.
