In parallel with the removal of tariffs under the PSFTA, Singapore and Panama have agreed to simplify their customs procedures to facilitate the flow of goods between the two countries.

Key facilitative commitments under this chapter include self-certification for the claiming of preferential tariffs. For Singapore-originating goods, an importer would have to prove that the goods are of Singapore origin via the presentation of a certification of origin in order to claim preferential tariffs on the goods in question. The list of data elements to be included in the certificate of origin are appended in Annex 4.6.

Under the Agreement, the Singapore exporter or producer can make this certification of origin on the export invoice without the need for a formal certificate of origin. Each Party shall provide that an exporter and a producer in its territory that completes and signs a certification of origin shall maintain in its territory, for three years after the date on which the certification of origin was signed.

Furthermore, to facilitate the trade in low-value consignments, the requirement of a certification of origin is waived if the value of the consignment is below US$1,000.

Advanced Ruling

The customs authorities in each country will, on the request of the trader, prior to the importation of the good into its country, provide an advance ruling on the eligibility of originating goods for preferential tariffs, providing traders with greater certainty on the status of their goods at the country of import. The customs administrations of both Parties may establish a validity period for an advance ruling of not less than 2 years from the date of its issuance.

The importing Party may modify or revoke an advance ruling:

(a)	if the ruling was based on an error of fact;
(b)	if there is a change in the material facts or circumstances on which the ruling was based;
(c)	to conform with a modification of this Chapter; or
(d)	to conform with a judicial decision or a change in its domestic law.
