For goods to be exported to the US under the USSFTA, the good must first fulfil the origin requirements to be eligible. You may wish to refer to details on the USSFTA to see if your good meets these requirements.

After you have ensured that the goods being exported to the US meet USSFTA requirements including the product specific rules of origin:

• Have your US importer file customs declarations through the Automated Commercial Environment (ACE). The US CBP has informed Singapore Customs that the current process for the US importer filing a US Customs Declaration remains unchanged at this juncture.

• Your importer’s broker must enter the appropriate Special Program Indicator (SPI) in ACE to claim preferential tariff treatment under the USSFTA.

• Be prepared to provide supporting documentation (e.g., certificate of origin or any other relevant information) if requested by the US CBP.

• You may also wish to apply to the US CBP for an advance ruling to determine whether the good qualifies as “Singapore-originating” for the purposes of the USSFTA, before it is exported to the US.

• The US CBP may conduct verification of origin checks by requesting information directly from manufacturers or exporters, or through the US importer. Singapore Customs may also facilitate visits to Singapore-based manufacturers or exporters, if requested by US CBP, for this purpose.
