Quick practical tips

• Taxes & duties: Singapore GST/import rules apply — imported parcels may incur GST or duties (IRAS/Singapore Customs guidance is the authoritative source). If the CIF/imported value exceeds the relief threshold, GST is payable; since Jan 2023 overseas vendors registered for GST may collect GST at point of sale. See IRAS for details. (iras.gov.sg)
• Authentication & returns: For high‑value or pre‑owned buys use platforms with authentication (Vestiaire, The RealReal, dedicated consignment shops) and check return/insurance policies before purchase. (apps.apple.com)
• Shipping savings: If an etailer doesn’t ship or charges high international fees, services that consolidate international parcels (e.g., Buy&Ship-type services) are commonly used by Singapore shoppers — but compare total landed cost (price + shipping + GST). (buyandship.com.sg)
