Foreign dealers carrying on a business of regulated dealing, or business as an intermediary for regulated dealing, in Singapore on a transitory basis (i.e. for not more than a total of 90 days in a year) are exempted from the requirement to register under Part 2 of the Precious Stones and Precious Metals (Prevention of Money Laundering, Terrorism Financing and Proliferation Financing) Act ("PSPM Act") and Section 19 of the PSPM Act.

However, foreign dealers are still required to comply with all other regulatory requirements in the PSPM Act and Regulations which include filing of Cash Transaction Reports for designated transactions exceeding S$20,000 received as payment in cash or cash equivalent and Suspicious Transaction Reports.

You may wish to refer to the PSPM Act and Regulations on http://www.go.gov.sg/acd for details of the aforesaid requirements.
