Singapore is consistently ranked the world's easiest place to trade. Its TradeNet single-window system processes most import permits in under 10 minutes, and Singapore applies 0% customs duty on virtually all goods. As a major transhipment hub, Singapore handles over 37 million TEUs annually and serves as the gateway for goods redistributed across Southeast Asia. Understanding TradeNet, GST at import, and controlled goods procedures is essential for importers using Singapore as an entry or distribution point.

Singapore Import Permit Process — Step by Step
- Appoint a Singapore Customs-licensed Declaring Agent (DA)

- DA keys in: HS code (8-digit Singapore Customs classification), CIF value, origin country, package count
- System checks against agency integration — if controlled good, agency approval triggered automatically
- Non-controlled: permit auto-approved within minutes
- Controlled: wait for agency approval (SFA, HSA, etc.) before permit issues
- Pay GST via GIRO or interbank transfer
- Present permit number at port/airport for cargo release
Singapore GST for Businesses
GST-registered Singapore businesses recover import GST as input tax:
- Claim import GST on monthly/quarterly GST return (Form GST F5)
- Net GST position: GST paid at import offsets GST collected on sales
- Major Exporter Scheme (MES): approved exporters import without GST payment; cash flow benefit for large-volume importers who re-export most goods
- Approved Trader (AT) status: faster customs processing for trusted high-volume traders
