Temporary Export Permit Singapore: 13 GST Scenarios Checked
A machine sent overseas for repair, or a display unit sent to a trade fair, can come back to Singapore without a second GST bill. Whether it does starts with the temporary export permit Singapore Customs asks for before the goods leave. We worked 13 business situations through our reading of Customs' published rules, and our checker and a second reader, working blind, agreed in 13 of 13.
If the question comes up late, the machine may already be crated. The repairer overseas is waiting, and finance is asking whether the company will pay GST again when the machine comes home.
Singapore Customs does answer the question.
The answer is spread across the Temporary Import/Export Scheme pages, the page on re-importing goods, and a string of AskGov replies. Each AskGov reply answers a single question.
This guide puts them side by side for business owners who send their own GST-paid goods out and bring them back. It covers the permits, what happens when parts are added, how long the goods can stay away, and where an ATA Carnet fits.
Rules checked against Singapore Customs, AskGov and IRAS pages on 30 September 2026.
Key takeaways
Get the Out (TCI) permit, a Customs Out (Temporary Consignment) permit, through TradeNet before the goods leave. Relief depends on it.
Bring the goods back on a Customs In-Non-Payment (TCI) permit, which Customs says the same exporter should file, quoting the Out permit number.
Repairs and trade samples have three months to come back.
New parts fitted overseas carry GST, unless the repair was free under a warranty or guarantee.
If the goods change form, HS code or function overseas, GST is payable on them.
Liquor and tobacco products are excluded.
What does paying GST twice actually mean?
It means paying import GST on goods that already carried it. A temporary export permit is one of the conditions for avoiding that.
Goods in question here are GST-paid or duty-paid, or made in Singapore. Bringing them back from an overseas repair is a re-import. Customs' page on re-importing goods says all re-imports may incur GST and/or duty (Singapore Customs). Singapore's current GST rate is 9% (IRAS).
That's what the Temporary Import/Export Scheme is for. Customs' overview says it lets you send GST- or duty-paid goods out for a while and bring them home with no second round of GST or duty, where applicable (Singapore Customs, TIS overview). AskGov agrees: goods made locally or already GST-paid, sent out on a temporary basis, may come back in without GST being paid again (AskGov, Singapore Customs).
It comes with conditions. Most of them are met, or missed, before the goods leave.
Which goods and purposes qualify for a temporary export?
GST-paid or duty-paid goods qualify for a set list of purposes. Intoxicating liquor and tobacco products are excluded.
Singapore Customs' table of qualifying goods and purposes for export lists these (Singapore Customs):
Type of goods | Purpose |
All GST and/or duty-paid goods, excluding intoxicating liquor and tobacco products | Repairs; exhibitions, fairs, shows, performances or similar events; loan or rental |
Bona fide trade samples | Soliciting trade |
Horses, private or recreational boats, aircraft or vehicles | Sports, racing or similar events |
For a business sending out its own equipment, the first row is the one that matters: a production machine, a test instrument, a display unit.
Two limits sit outside that table. If your goods are controlled, you need approval from the relevant Competent Authority before you apply for the permit (Singapore Customs). Our guide to licence versus permit for controlled goods explains that split. Motor vehicles follow their own permit rules, which this guide does not cover.
What has to happen before the goods leave Singapore?
Before departure, you need a temporary export permit, and officers have to endorse it at export. Customs is plain about the timing: to qualify, the permit must be obtained before departure from Singapore.
Singapore Customs sets out the export steps like this (Singapore Customs):
Check whether the goods are controlled. If they are, get Competent Authority approval first.
Apply for a Customs Out (Temporary Consignment, TCI) permit through TradeNet, before the goods are exported.
Include the supporting documents with the TradeNet declaration: a cover letter stating the purpose and the duration of the temporary export, the commercial invoice, the packing list, and any other documents Customs asks for.
Produce the permit and the documents at export cargo clearance, for endorsement by the checkpoint officers.
The re-import page adds one condition that is easy to miss: when the goods went out, you already meant to bring them back (Singapore Customs). Your cover letter's purpose and duration are where that intention is written down.
Our view: the cover letter carries more weight than it looks. Three months from now, it's the document that shows why the goods left.
If you're choosing between outward permit types for other shipments, our guide to which outward permit fits which export sets them out. As for cost, Customs puts a typical TradeNet permit at about S$3.19 for traders who file their own. That is a S$0.90 statutory fee plus S$2.29 in processing and messaging fees (Singapore Customs). We break down what a TradeNet permit costs in more detail.
How do you bring the goods back without paying GST again?
The same exporter files a Customs In-Non-Payment (TCI) permit and quotes the Out permit number. Your goods then come back without GST, if every condition is met.
Customs lists the return steps (Singapore Customs):
Before the goods come back, the same exporter applies for the In-Non-Payment (TCI) permit through TradeNet.
Declare the earlier Out (Temporary Consignment) permit number in the "Previous Permit No." field.
Attach a cover letter giving the reason for the re-import, the temporary export permit, and the commercial invoices from both legs (export and import), bills of lading or air waybills, and packing lists, if any.
Produce the permit and documents at re-import clearance for endorsement.
TCI is the same code you'll see as a declaration type in the TCI row in our import permit declaration-type table.
Only part of the shipment coming back? That's allowed. File the In-Non-Payment (TCI) permit, write "Partial return of goods vide Invoice number XXX" in the Traders Remarks field, and declare the earlier Out (TCI) permit in the Previous Permit Number field (AskGov, Singapore Customs).
Who files the temporary export and re-import permits?
The exporter does, and Customs names the same exporter for the return. Its procedure says the same exporter should apply for the In-Non-Payment (TCI) permit before the same goods come back, and declare the earlier Out permit number (Singapore Customs).
Both permits go through TradeNet. Our guide to filing your own TradeNet permits or appointing an agent sets out what each option involves.
Our view: whoever files, some of the paperwork can only come from your side. That means the cover letter's purpose and duration, and the repairer's certificate.
What if the repairer fits new parts on goods sent overseas for repair?
The original machine still comes back without GST. The new parts don't, unless the repair was free under a warranty or guarantee.
For non-dutiable goods sent out for repair, Customs limits the GST relief to the parts that were there originally. GST is payable on the new parts. One exception applies: a free repair done under a warranty or guarantee agreement (Singapore Customs).
AskGov adds how the parts are valued: GST at the prevailing rate on their Cost, Insurance and Freight (CIF) value (AskGov, Singapore Customs). The added parts need their own In-Payment (GST) permit (AskGov, Singapore Customs).
To get the relief, Customs asks for:
a repairer's certificate stating whether any new parts went in;
an invoice for the new parts, if any, or proof that the repair was done at no charge; and
for a non-taxable person, proof that the GST was paid before and not refunded.
Where GST applies to the parts, the return uses two permits: a Customs In-Payment (GST) permit and a Customs In-Non-Payment (TCI) permit.
Our view: ask the repairer for the certificate when you send the purchase order, not when the machine is on its way back. It's a document only the repairer can issue.
A replacement is different from a repair. If the overseas supplier sends a new unit instead of fixing yours, AskGov's answer is direct: GST is payable on replacement goods, declared on an In-Payment (GST) permit (AskGov, Singapore Customs).
When does the GST relief fall away?
When any condition is missed, or when the goods are changed overseas. Customs says GST and/or duty is payable if a single exemption condition is missed, or if, in its words, "the goods were manipulated, processed, or modified overseas" (Singapore Customs).
In practice, the published rules name these situations:
No Out (TCI) permit at export. This permit is one of the exemption conditions, so goods shipped on an ordinary export permit don't meet it.
The goods changed. If goods sent out temporarily are altered overseas so that their form, function or HS code changes, GST is payable. The goods must stay identifiable as the same items that left (Singapore Customs). Our post on why the HS code on the permit has to be right covers the classification side.
Excluded goods. Intoxicating liquor and tobacco products are not on the qualifying list.
A replacement unit comes back. GST is payable on it, as above.
A separate route covers goods you sold and exported on an ordinary Out (Direct) permit, which then come back damaged or rejected.
Such goods may be re-imported without GST if every condition on Customs' list is met.
Those conditions include that the goods return in the same condition and that the GST paid earlier was not claimed or refunded. For a GST-registered company, the re-import goes on a Customs In-Payment (GST) permit. GST may then be claimed from IRAS (Singapore Customs). That's a returns route, not a repair route.
If a permit was filed on the wrong declaration type, see how to amend or cancel a permit that was filed wrongly.
How long can the goods stay overseas?
Three months for repairs and trade samples. For other purposes, the Temporary Export Duration page sets no limit. Another Customs page reads differently, so confirm before a long trip.
According to the Temporary Export Duration page, trade samples and goods sent for repair must come back to Singapore within three months of the export date. For all other goods and purposes, it says there is no limit (Singapore Customs). There's no requirement to extend the temporary export period. If repair goods or trade samples miss the three months, give your explanation in the In-Non-Payment (TCI) application, and Customs will assess it.
A second Customs page reads differently.
The page on re-importing goods lists "re-imported within 3 months from export, or within an approved extension by the Director-General" among the exemption conditions. That page allows the extension only for genuine trade samples and repair goods (Singapore Customs). Both pages were updated within a month of each other in 2026. They don't say the same thing about goods going to an exhibition.
Where the two pages differ, confirm the position with Singapore Customs before the goods leave.
For goods returning after three months, AskGov lists what to attach to the re-import permit: the cover letter, the temporary export permit, both sets of invoices, bills of lading or air waybills and packing lists, and documentation that the goods were made locally, or the payment permit if they were bought overseas (AskGov, Singapore Customs).
Temporary export permit or ATA Carnet?
An ATA Carnet is a customs document that lets goods leave temporarily and be brought back in. Customs describes it for exhibitions, fairs and similar events in signatory countries. A temporary export permit is the TradeNet route.
According to Singapore Customs, the Carnet carries a declaration form for every border crossing. Consumables, for example food, alcoholic drinks or tobacco, can't travel on one (Singapore Customs).
For a Carnet issued in Singapore, Customs says (Singapore Customs):
Singapore entities may contact the Singapore International Chamber of Commerce (SICC) to obtain one, and check with SICC whether the destination accepts Carnets for the intended purpose.
Most Carnet exports need no customs permit. Strategic goods need a Strategic Goods (Control) permit before export.
The goods must come back by the earlier of six months from the date of export, or one day before the Carnet's validity date.
Question | Temporary export permit (TCI) | ATA Carnet (local) |
How it's filed | Out (TCI) and In-Non-Payment (TCI) permits through TradeNet | Carnet obtained through SICC; most exports need no customs permit |
Typical purposes named by Customs | Repairs, exhibitions and similar events, loan or rental, trade samples | Exhibitions, fairs and similar events in signatory countries |
Time limit | Three months for repairs and trade samples | Earlier of six months from export or one day before validity |
Our view: for a repair job, the Customs pages point to the TCI permit. The Customs Carnet pages we read describe exhibitions, fairs and similar events, and don't mention repairs.
Temporary export permit Singapore: 13 cases we ran through the rules
We wrote down 13 business situations before running any of them, including the awkward ones. Our checker gave each a route from our reading of the published rules. A second reader, working blind, worked each one from the same pages without seeing the checker's answer. Both matched in 13 of 13.
Case | Situation | Route in the published rules |
T01 | Machine out on Out (TCI) for repair, back in 2 months, no new parts | In-Non-Payment (TCI); no GST on the machine |
T02 | Repairer fits a new motor and charges for it | TCI for the original parts; In-Payment (GST) on the new parts |
T03 | New parts fitted free under warranty | TCI; relief also covers the new parts; repairer's certificate and proof of no charge |
T04 | Shipped for repair on an ordinary Out (Direct) permit | No temporary export relief; GST and/or duty payable on return |
T05 | Repair overruns; back after 4 months | Explain in the TCI application; Customs assesses |
T06 | Demo unit at an overseas exhibition for 5 months | TCI under the Duration page (no limit); see Limits |
T07 | Modified overseas so the HS code changes | GST payable on the goods |
T08 | Duty-paid wine to an overseas trade fair | Not eligible; liquor excluded |
T09 | 5 display units out, 3 come back | Partial TCI return with a Traders Remarks note |
T10 | Controlled item going for repair | Competent Authority approval first, then Out (TCI) |
T11 | Exhibition goods on a local ATA Carnet | No customs permit for most Carnet exports; back by the earlier of 6 months or 1 day before validity |
T12 | Supplier sends a replacement unit instead | In-Payment (GST) on the replacement |
T13 | Sold goods rejected by the buyer, back unaltered, GST-registered exporter | Returns route: In-Payment (GST), then claim from IRAS |
Across cases T01 to T04, the route turned on the permit used at export and the repairer's paperwork.
Method
We read the Singapore Customs pages on qualifying goods, permit procedures, duration, additional requirements, the scheme overview, the ATA Carnet, and re-importing goods, plus the AskGov answers linked above, all on 30 September 2026. We turned their conditions into a route checker with twelve route labels.
We fixed the 13 situations in writing and froze a copy with a checksum, all before the checker ran. A second reader worked out every expected route from the saved page text alone, with no access to the checker. That reader quoted the sentence that decided each case. We then compared the two.
Motor vehicles and Free Trade Zone movements were left out on purpose.
Limits
The checker describes what the published pages say. It doesn't decide eligibility: Singapore Customs assesses each application, and a Competent Authority decides on controlled goods.
Case T06 rests on the Temporary Export Duration page. Read against the re-importing page alone, the same case could go the other way.
Case T05's outcome after assessment isn't published. For T13, the rule also requires that the GST paid earlier was not claimed or refunded. Goods that never come back, and motor vehicles, aren't covered.

Your checklist before the goods are packed
Confirm the goods were GST-paid or duty-paid and aren't liquor or tobacco.
Check whether they're controlled. If so, get Competent Authority approval first.
Write the cover letter: purpose and duration of the temporary export.
File the Out (TCI) permit through TradeNet before the goods leave, with the commercial invoice and packing list.
Make sure the permit and documents are presented for endorsement at export clearance.
Ask the repairer, in the purchase order, for a certificate stating whether new parts were added, and an invoice for any parts.
Diary the three-month date for a repair or trade sample.
Keep the export permit number, invoices, bills of lading or air waybills and packing lists in one file for the In-Non-Payment (TCI) permit.

Frequently asked questions
Do I pay GST again when my machine comes back from an overseas repair?
Not on the original machine, if the conditions are met. It must have left on a Customs Out (TCI) permit, come back within three months (or explain a later return in that permit application) on an In-Non-Payment (TCI) permit, and not been changed in form or function. New parts carry GST on their CIF value unless the repair was free under warranty.
Can I apply for the temporary export permit after the goods have left?
Customs' pages say no. The permit must be obtained, and the application submitted, before the goods are exported. That permit then has to be endorsed at export clearance.
Do I need to extend a temporary export permit?
No. Customs says there's no need to extend the temporary export period. When the goods are ready to come back, apply for the In-Non-Payment (TCI) permit. For repair goods or trade samples returning after three months, give your explanation in that application for Customs to assess.
What documents does the repairer need to give me?
A certificate confirming whether new parts were added, and an invoice for any new parts, or proof that the repair was done at no charge. A non-taxable person also needs proof that the GST was paid before and not refunded.
Can only some of the goods come back?
Yes. File the In-Non-Payment (TCI) permit, write "Partial return of goods vide Invoice number XXX" in Traders Remarks, and declare the earlier Out (TCI) permit number in the Previous Permit Number field.
Is an ATA Carnet better than a temporary export permit?
It depends on the purpose. Customs describes the Carnet for exhibitions, fairs and similar events in signatory countries, obtained through SICC, with a return date of the earlier of six months or one day before validity. For a repair job, the Customs pages we read point to the TCI permit.
