Import From Taiwan to Singapore: What Actually Costs You
When you import from Taiwan to Singapore, what actually costs you is not duty. You almost certainly pay zero import duty, because Singapore levies duty on only 4 categories of goods and Taiwan rarely ships any of them. The cost that decides your landed price is GST on the CIF value, and no trade agreement reduces GST.
That single fact reorders the whole job. Most guides send you chasing a Declaration of Origin under the Singapore–Taiwan trade agreement before your first shipment moves. For a Singapore importer, that paperwork usually buys you nothing. Your money and your attention belong somewhere else entirely.
I've watched SME owners spend two weeks negotiating origin paperwork with a Taipei supplier for a container of machinery, then get surprised by the tax bill on arrival. The paperwork was never the problem. The valuation was.
Key Takeaways
Singapore charges import duty on exactly 4 categories: intoxicating liquors, tobacco products, motor vehicles and petroleum products (Singapore Customs). Everything else is non-dutiable.
Because of that, ASTEP preference is usually worth zero on your import leg — its tariff value points the other way, toward your exports into Taiwan.
GST is levied on the CIF value — cost, insurance and freight — plus any duties. Freight rises, and your tax bill rises with it.
GST relief on goods valued at S$400 CIF or less applies only to post and air. It does not apply to sea or land (Singapore Customs).
ASTEP entered into force 19 April 2014. On Chinese Taipei's side, tariff-free coverage reached 99.9% on 1 January 2023 and hits 100% on 1 January 2028 (Enterprise Singapore).
Singapore Charges Duty on Only Four Things
Singapore Customs is unusually blunt about this. Dutiable goods fall into 4 named categories: "Intoxicating liquors", "Tobacco products", "Motor vehicles" and "Petroleum products". Every other imported good is non-dutiable and attracts GST only.
Count them: 4. Not 40, not 400. If your goods aren't liquor, tobacco, a motor vehicle or a petroleum product, your duty line reads 0.
Now look at what Taiwan actually ships: semiconductors, machine tools, electronic components, industrial chemicals, bicycle parts, packaged food, cosmetics. None of it sits in those 4 boxes.
So the duty rate on your Taiwan shipment is already zero before you negotiate anything. There's no preference to claim, because there's no tariff to remove.
Our verdict: skip the origin paperwork on a standard Taiwan import. Spend that time on your HS code and your declared value instead — those 2 fields decide what you actually pay. Our HS code classification guide for Singapore walks through the classification traps that do cost money.
What ASTEP Actually Does — and Which Direction It Points
The agreement's full name is a mouthful: the Agreement between Singapore and the Separate Customs Territory of Taiwan, Penghu, Kinmen and Matsu on Economic Partnership. Everyone calls it ASTEP. It entered into force on 19 April 2014.
Read Enterprise Singapore's own numbers carefully, because they explain the asymmetry.
Side | Tariff-free coverage | Date |
Chinese Taipei — already free before ASTEP | 82.5% | pre-2014 |
Chinese Taipei — on entry into force | 96.7% | 19 Apr 2014 |
Chinese Taipei | 98.2% | 1 Jan 2018 |
Chinese Taipei | 99.9% | 1 Jan 2023 |
Chinese Taipei | 100% | 1 Jan 2028 |
Singapore's exports into Taiwan | ~98% immediate | 19 Apr 2014 |
Every one of those percentages describes tariffs Taiwan removes on goods arriving from Singapore. That's the side with something to give away, because Taiwan had tariffs to begin with. Singapore didn't.
So ASTEP is genuinely valuable — if you're selling into Taipei. If you're buying from Taipei, it's mostly a document you'll never need.
When the origin paperwork does earn its keep
3 situations flip the answer:
You're exporting Singapore-made goods into Taiwan. Then the Declaration of Origin under Annex 4E is the instrument that unlocks the tariff-free treatment above.
You're importing one of the 4 dutiable categories — a vehicle, or liquor. Singapore Customs lists preferential treatment for "certain dutiable goods (for example, stout or porter, beer including ale, medicated samsu, other samsu)".
Your buyer downstream needs proof of origin for their import into a third market.
If none of those describe you, you're free to stop reading about origin rules. That's a genuine relief, and few guides will tell you so.
Is a Declaration of Origin Worth the Effort for a Taiwan Import?
For most Singapore importers, no. The duty you'd save is zero, because the duty you owe is already zero.
Where it matters, ASTEP's rules of origin set a regional value content minimum of 35–45%, with a de minimis allowance letting non-originating materials make up to 10% of the free-on-board value without breaking the tariff classification requirement. Those thresholds decide whether goods qualify — they don't create a saving where no tariff exists.
If you do claim preference on a dutiable import, Singapore Customs sets 2 hard clocks: supporting documents go in within 1 week of clearance, and any refund request through TradeNet must be lodged within 1 year of duty payment. Miss the second one and the money is gone — there's no appeal on a lapsed refund window.
The Number That Decides Your Landed Cost: GST on CIF
Here's where your money actually goes.
Singapore Customs states that the prevailing GST is levied on the Cost, Insurance, Freight value. The taxable amount is the customs value of the goods plus all duties — or, if the goods changed hands more than once before import, the last selling price plus all duties.
Read that again, because it contains the trap. Freight is inside the taxable base. When your Taipei–Singapore ocean rate jumps, you don't just pay more freight. You pay tax on the increase too.
That's the line most SME owners miss when they compare quotes. A forwarder quoting a lower all-in rate isn't only saving you the freight difference — they're shrinking the number your tax is calculated on. Our landed cost calculation guide shows the full stack.
Singapore's import GST rate is 9%. On a CIF value of S$13,020 that's S$1,171.80 — payable whether or not any trade agreement covers your goods. Rates are set by policy and can change, so confirm the current rate with IRAS before you build it into a customer quote.
What Happens at the S$400 Line — and Why Sea Freight Ignores It
Singapore Customs grants GST relief "only for goods imported by post or air, excluding intoxicating liquors and tobacco products, with a Cost, Insurance and Freight (CIF) value not exceeding S$400."
Then comes the sentence that catches people: "GST relief does not apply to goods imported by sea or land."
So the S$400 line is not a universal allowance. It's an air-and-post rule.
A S$350 sample by air courier from Taipei: within the relief threshold.
The same S$350 sample by sea LCL: no relief. GST applies from the first dollar.
From January 2023, GST applies to low-value goods not exceeding S$400 imported by post or air when bought from GST-registered overseas vendors — collected at purchase rather than at the border.
Our verdict: never assume your sea shipment inherits the parcel rule. We've seen buyers split an order into "small" sea consignments believing each would land under the threshold. Every one of them was taxed. The S$400 line simply doesn't exist on water. Our guide to the S$400 rule on parcels covers the parcel side in detail.
Import From China to Singapore: How the Taiwan Route Differs
Bringing goods in from mainland China works on different paperwork, even when the cargo looks identical. China imports can claim preference under ACFTA using Form E, and under RCEP using Form RCEP — both of which Singapore Customs lists as accepted origin documentation. Taiwan sits outside both of those frameworks and uses ASTEP's own declaration instead.
For a Singapore importer the practical difference is smaller than it sounds, because the duty outcome converges at zero either way. Where it genuinely diverges is consolidation. Taiwan's export volumes into Singapore are thinner than China's, so LCL sailings are less frequent and consolidation windows run longer.
That schedule gap is the real cost of the Taiwan lane, and it doesn't appear on any quote. A container that waits 4 extra days for consolidation is 4 days of working capital you've committed with nothing on the water.
If your supplier base spans both, our China to Singapore import guide and our RCEP guide explain which instrument applies where. For consolidation mechanics, see our LCL sea freight guide.
Import GST Singapore: What You Can Defer
You can't reduce GST with a trade agreement. You can change when you pay it.
Singapore runs schemes that let qualifying businesses defer or suspend import GST rather than paying it at the border and reclaiming later. For an importer running regular Taiwan shipments, that's a cash-flow lever worth more than any origin certificate you'll ever file — the tax total doesn't change, but the timing does, and timing is what strains a growing SME.
Eligibility, application and conditions sit with the authorities, and they change. Our guide to deferring GST on Singapore imports compares the routes. Confirm your standing with IRAS before you plan around it.
Which Permit You File, and When
Singapore Customs is direct: imported goods are subject to GST and/or duty, and a customs permit is required to account for the import and tax payment. Permits are submitted through TradeNet, which is also where amendments, cancellations and refund requests go.
A few situations don't require a permit, and Singapore Customs maintains that list. Check it against your specific consignment rather than assuming — the exceptions are narrow and the penalty for guessing wrong lands on you, not your forwarder.
Practical sequence for a first Taiwan shipment:
1. Classify the goods and settle the HS code before the supplier ships. 2. Establish the customs value on the CIF basis, freight and insurance included. 3. Confirm whether the goods need any controlling-agency clearance. 4. File the permit via TradeNet ahead of arrival. 5. Keep supporting documents ready — Customs sets a 1-week window after clearance for preference claims.
Our Singapore customs clearance guide for importers covers the filing detail.
Air or Sea From Taipei?
Sea, for anything that isn't urgent or tiny. That's the honest default, and it's not close.
The exception is real though. Under the S$400 CIF threshold, air and post carry a GST relief that sea simply doesn't have. For genuine samples and small first orders, air can land cheaper on a total-cost basis even at a higher freight rate — the relief does the work, not the airline.
Above that line the arithmetic flips hard, because air freight enters the same CIF base that GST is calculated on. You pay the premium, then you pay tax on the premium. Our sea freight versus air freight comparison sets out the break-even logic.
Buy From Taiwan and Ship to Singapore: The Small-Order Route
Not every Taiwan purchase is a container. Plenty of Singapore buyers want 1 machine, a pallet of components, or a trial run of stock from a Taipei supplier who's never shipped here before.
The tax treatment doesn't change with your size. What changes is which threshold you can reach.
A small order sent by air courier with a CIF value of S$400 or under falls inside Singapore Customs' GST relief for post and air. That's the only genuinely cheap way to bring goods in, and it's capped tightly — the relief excludes intoxicating liquors and tobacco products regardless of value.
Push past S$400 and the relief vanishes entirely. Not on the excess — on the whole amount. A S$420 air shipment is taxed on all S$420, not on the S$20 above the line. That S$20 of extra order value can cost you far more than S$20.
Our verdict: if your first Taiwan order is genuinely a sample, keep it under S$400 by air and take the relief. If it's real inventory, stop optimising for the threshold and move to sea, where the relief never applied anyway and freight per unit collapses.
One caution on suppliers new to the Singapore lane. A Taipei factory that mainly ships domestically may not know what your permit needs, and may not produce a commercial invoice with the detail Customs expects. Ask for the invoice format before you pay the deposit, not after the goods are on a vessel.
How the CIF Base Is Built: A Worked Example
Figures below are illustrative, chosen to show the mechanism. Your real numbers come from your invoice and your forwarder's quote — but the arithmetic never changes.
Say you buy machine parts from a Taichung supplier. Goods value S$12,000. Ocean freight Kaohsiung to Singapore S$900. Marine insurance S$120.
Line | Amount |
Goods (FOB) | S$12,000 |
Ocean freight | S$900 |
Insurance | S$120 |
CIF — the taxable base | S$13,020 |
Import duty (non-dutiable goods) | S$0 |
GST at 9% | S$1,171.80 |
3 things to notice.
First, your duty is 0, and ASTEP could not have made it lower than 0.
Second, GST is calculated on S$13,020, not on S$12,000. The S$1,020 of freight and insurance is inside the base. That's an extra S$1,020 of taxable value created by moving the goods.
Third, if that same freight quote came in at S$1,600 instead of S$900, your taxable base rises to S$13,720 — and you pay tax on the extra S$700 as well as the freight itself. A S$700 rate increase costs you more than S$700.
This is why we push clients to compare all-in quotes rather than base rates. The freight line is taxed. Two forwarders quoting S$900 and S$1,600 aren't S$700 apart on your P&L — they're S$700 plus the tax on it.
What Does It Actually Cost to Clear a Taiwan Shipment?
Clearance cost splits into things you control and things you don't.
You don't control the tax base. GST sits on customs value plus duties, and the customs value is CIF — so freight and insurance are inside it whether you like it or not.
You do control 4 levers, roughly in order of how much they move the total:
Mode. Sea versus air changes both the freight number and the tax calculated on it.
Consolidation. LCL versus a full container changes your per-unit cost more than any negotiation on rate.
Classification. The HS code decides whether any controlling agency gets involved, which decides whether your goods wait.
Order size. Whether you cross the S$400 air relief line at all.
Notice what isn't on that list: origin paperwork. On a non-dutiable Taiwan import it moves nothing, which is exactly why we keep pointing you away from it.
Who Pays if the Declared Value Is Wrong?
You do. The importer carries the exposure, not the overseas shipper.
That matters because under-declaration is usually suggested by the supplier, framed as a favour. A Taipei factory offering to write a lower figure on the invoice isn't taking a risk — the declaration is made in your name, through your permit, on your TradeNet account.
Singapore Customs defines the valuation basis clearly: the customs value of the goods plus all duties, or the last selling price plus all duties where the goods were sold more than once before import. That second clause catches trading-company purchases, where goods pass through an intermediary before reaching you.
If your Taiwan supplier sells through a Hong Kong or Singapore trading arm, the last selling price is the one that counts. Get that straight before the permit is filed, because amending a declaration after clearance is slower and more visible than getting it right the first time.
What We Would Not Do
3 things we'd steer you away from on this lane:
Don't chase ASTEP preference on a non-dutiable import. You'd be negotiating for a discount on a bill of zero. It's the single most common wasted effort we see on this route.
Don't split sea consignments to duck the S$400 line. It isn't there. You'll pay GST on each piece and add handling charges for the privilege.
Don't let a supplier declare a value "to help with customs". Under-declaration is the importer's exposure, not the shipper's, and the customs value basis is defined — CIF, plus duties, or last selling price where the goods were sold on before import.
Frequently Asked Questions
How to import from China to Singapore compared with Taiwan?
Both land duty-free for most goods, since Singapore taxes only 4 categories. The paperwork differs: China imports use ACFTA Form E or RCEP Form RCEP, while Taiwan uses the ASTEP declaration. The practical difference is consolidation frequency, not tax.
Can I buy electrical appliances from China to Singapore?
Yes, and the same principle applies to Taiwan. Electrical appliances aren't in Singapore's 4 dutiable categories, so no import duty applies. GST is levied on the CIF value. Some appliances need safety registration with the relevant controlling agency before sale — check that before you order.
Can I use proxy shopping and global parcel forwarding to buy from overseas retailers that do not ship directly to Singapore?
Yes. A forwarding address gives you a local delivery point the retailer will ship to, then the parcel is forwarded on. GST relief applies to post and air consignments with a CIF value not exceeding S$400, excluding liquor and tobacco. Above S$400, GST applies to the full amount.
What is the Singapore import tax on goods over S$400?
There's no separate "over S$400" tax. The S$400 figure is the ceiling for GST relief on post and air imports. Above it, GST applies to the entire CIF value rather than the excess. Goods arriving by sea or land get no relief at any value.
Does ASTEP reduce GST on Taiwan imports?
No. ASTEP addresses tariffs, not GST. No free trade agreement reduces Singapore's GST. Since most Taiwan goods carry no Singapore tariff to begin with, the agreement's import-side effect for a typical shipment is nil.
If you're setting up a Taiwan lane and want the valuation and permit sequence checked before your first container books, our team will walk your specific commodity through it. Bring your commercial invoice, your intended HS code and your incoterm — that's enough for a real answer rather than a request for more information.
