Rules of Origin Singapore: 6 Checks Before Quoting FTA Duty
Before you promise a buyer FTA duty treatment, check three things: which agreement their country uses, the rule that agreement sets for your product's HS code, and whether your materials and processing meet it. The rules of origin Singapore exporters face are decided agreement by agreement, and Singapore Customs' origin rulings don't cover exports.
Usually the request arrives during price negotiations. Your buyer says their customs will charge nothing if the goods come from Singapore under the free trade agreement. They ask you to confirm it before they sign.
Say yes too early and the promise sits in the contract. The goods are judged later, by the buyer's customs, against rules you haven't read.
Rules checked against Singapore Customs, AskGov and the Enterprise Singapore page Customs links to, on 30 September 2026.

Key takeaways
Each FTA sets its own origin rules. Goods that qualify under one agreement may not qualify under another.
What matters is the rule listed for your product's HS code in that agreement, not a general percentage.
Packing, labelling, sorting and simple assembly are on Customs' list of minimal processes that don't make goods Singapore-originating. Each FTA sets its own list, so check the one you're quoting under.
A preferential certificate covers customs duty only. GST and excise still apply, and some goods are excluded from the preference altogether.
Singapore Customs' origin rulings cover goods imported into Singapore only. For your export, Customs sends you to the importing country's customs authority.
Why can't you just tell the buyer the goods qualify?
Because "made in Singapore" and "originating under the FTA" are two different tests. One is a commercial description; the other is a legal status that exists only inside a specific agreement.
Singapore Customs states it directly. Goods only count as Singapore-originating for an FTA partner's lower rate if they pass the origin test written into that particular agreement, and the agreement has to be in force (Customs, Rules of Origin Overview). Its handbook for preferential certificates adds that rules of origin vary from FTA to FTA, so a good that qualifies under one FTA may not qualify under another (Customs PCO handbook, December 2024).
So a product that sails through for a buyer in Malaysia can fail for a buyer in India, even from the same production line. The same gap shows in a question Singapore Customs answers on AskGov: "Why is my customer required to pay import duty even though I obtained a Preferential Certificate of Origin (PCO) for the export?" (AskGov). That gap starts at the quote.
Rules of origin Singapore Customs applies to FTA exports
An originating good falls into one of two groups: wholly obtained, or manufactured from non-originating materials that were transformed enough to meet the agreement's rule (PCO handbook).
Most quotes go wrong on the handbook's definition of a non-originating material. It covers three kinds of material:
materials imported from a country that isn't a party to the FTA;
materials produced in a party to the FTA that don't meet its rules of origin;
materials whose origin can't be determined.
That third line matters for a trader or small manufacturer. If a supplier can't tell you where a component came from, the handbook treats it as non-originating. Customs' best-practice list makes the same point from the other side. It warns exporters off guessing where goods or materials come from and off trusting supplier information nobody has verified, and asks them to recheck supplier details and manufacturer declarations on a regular basis (Customs, Best Practices).
So open your bill of materials first, not the certificate application.
Is your product covered by the FTA at all?
Check coverage before origin. A product can be perfectly Singapore-made and still get no preference, because the agreement doesn't cut the duty on it.
Singapore Customs points exporters to Enterprise Singapore's Tariff Finder to see three things: whether the goods are covered under an FTA, the corresponding preferential tariffs, and which FTA is most suitable (Customs, Origin Documentation Overview). Enterprise Singapore says the tool shows basic (MFN) duties and preferential tariffs for import. It also shows the requirements to import into more than 120 destinations, including the origin rules under Singapore's FTAs (Enterprise Singapore).
Two limits from AskGov belong in every quote conversation. Some goods sit outside an agreement's preference altogether, and for those a preferential certificate does nothing. Where the preference does apply, it touches customs duty alone: GST and excise are still charged (AskGov).
So when a buyer says "zero duty", ask whether they mean customs duty alone, and whether they've checked their product line in their own tariff.
Wholly obtained or substantially transformed?
Wholly obtained goods are the simple case: things grown, harvested, born and raised, or produced entirely from originating materials. One example in the handbook is plastic bottles used and collected in Singapore (PCO handbook).
The handbook says goods made with non-originating materials must undergo substantial transformation. That is measured by a change in tariff classification (CTC), regional value content (RVC) or a process rule, used alone or in combination depending on the agreement. It also notes that most goods exported from Singapore fall into this category.
Goods that aren't seeking preferential treatment fall under Singapore's non-preferential rules instead. Customs' overview page gives four ways in: goods wholly obtained in Singapore; goods made here with local content of at least 25% of the ex-factory price; a tariff shift at the 6-digit level; or, for HS Chapters 27 to 40 only, a chemical reaction (Customs, Rules of Origin Overview).
These rules also govern the ordinary Certificate of Origin. They don't unlock FTA rates. On AskGov, Customs is clear that an ordinary CO earns the goods no preferential rate (AskGov).
The same rules reach your permits. For goods not seeking preferential treatment, Customs says Singapore can go in the Country/Region of Origin field of an import, export or transhipment permit only if the goods meet these criteria (Customs, Rules of Origin Overview). A wrong origin assumption can therefore sit in the export permit as well as in the quote; our guide to amending or cancelling a permit covers the correction routes.
How does the tariff-shift test work?
This test and the value test below run on the same list: the materials that went into the finished product, with each one's origin, HS code and value.
Depending on the agreement, the non-originating materials must sit in a different HS chapter (2 digits), heading (4 digits) or sub-heading (6 digits) from the finished good. So, as the handbook points out, you can't run this test without HS codes for both the finished product and every non-originating input (PCO handbook).
If your HS codes are shaky, so is the test. Our guide to getting the HS code chain right covers where that usually slips.
How does the value-content test work?
Under regional value content, a set share of the good's value must originate in the FTA parties. You can work it out two ways, the handbook says, both against the FOB value: build-up (local materials plus direct labour, overheads and profit) or build-down (FOB value minus non-originating materials).
A worked example in the handbook shows how close the line can be. A biscuit exported under ATIGA, with a 40% RVC rule, comes out at 36% and is non-originating. Count the Malaysian flour and eggs under ATIGA's accumulation provision, and the same biscuit reaches 83% and qualifies. The recipe didn't change; the paperwork behind two ingredients did (PCO handbook).
Handbook example (ATIGA biscuit, rule: RVC 40%) | RVC | Result |
Malaysian flour and eggs counted as non-originating | 36% | Non-originating |
Malaysian flour and eggs accumulated as ATIGA-originating | 83% | Originating |
Accumulation has a condition. The handbook says that to treat the Malaysian materials as originating, the producer would have to prove it by obtaining the ATIGA preferential certificate (Form D) for them. If your supplier can't give you that, you're left with the lower figure.
When do de minimis and accumulation help?
Two flexibilities are agreement-specific. De minimis applies only to the tariff-shift test. ATIGA, for example, allows a tolerance of 10% of the free-on-board value for non-originating materials that don't make the required change. Accumulation applies to both tests, but only with originating materials from parties to the same agreement (PCO handbook).
Both flexibilities apply only where the agreement provides for them, the handbook says, and de minimis varies between agreements. Check the text of the FTA you're quoting under.

General origin rules by agreement
The general rules in the handbook's Annex A show how far the agreements differ:
Agreement | General rule listed in the handbook |
ATIGA (ASEAN) | CTH or RVC 40% |
ACFTA (ASEAN-China) | RVC 40% |
AIFTA (ASEAN-India) | RVC 35% + CTSH |
AJCEP (ASEAN-Japan) | CTH or RVC 40% |
AKFTA (ASEAN-Korea) | CTH or RVC 40% |
CECA (India-Singapore) | QVC 35% + CTSH |
CSFTA (China-Singapore) | RVC 40% |
Treat that table as a starting point only. In the handbook's origin-determination chart, the general rule is the alternative to a product-specific rule. Those product-specific rules are arranged by HS classification number, so look up the rule listed against your own code.
Which processes never count towards origin?
Some work in Singapore doesn't count, however much of it you do. According to the handbook, simple or minimal work never counts towards origin under any agreement's criteria, and stacking several such steps together doesn't change that. Its examples include preserving goods for transport or storage, facilitating shipment, packaging or presenting goods for sale, and washing or cleaning (PCO handbook).
Singapore's non-preferential list on the Customs overview page is longer. It names the operations traders most often rely on: changes of packing, simple placing in boxes or bags, affixing marks or labels, simple mixing, simple assembly of parts into a complete product, and making up sets (Customs, Rules of Origin Overview). On that page, minimal processing alone doesn't make goods Singapore-originating.
If your Singapore step is repacking, relabelling or kitting, don't build a quote on Singapore origin. Each FTA also carries its own minimal-operations list, so check the agreement you're quoting under.
Who issues the proof of origin under each agreement?
The agreement decides who issues the proof. Singapore Customs lists three types of preferential proof of origin: a preferential CO issued by Singapore Customs, an origin declaration by Approved or Certified Exporters, and an origin declaration by the exporter, producer or importer (Customs, Origin Documentation Overview).
Where Customs issues the certificate, our guide on applying for a Singapore Certificate of Origin covers the steps and lead times. Our note on electronic Certificate of Origin rules covers the electronic side.
Customs runs three authorised self-certification regimes, under ATIGA, RCEP and the 2nd Protocol of AANZFTA. It tells applicants the outcome of an Approved or Certified Exporter application within 7 working days. Registration is valid for 3 years (Customs, AE/CE Scheme).
Other agreements run on self-certification. Customs lists 14 of them, among them SAFTA with Australia, CPTPP, the EU-Singapore FTA and the UK-Singapore FTA (Customs, Self Certification).
Under the EU agreement, AskGov says Singapore Customs will not issue a preferential CO at all (AskGov). The self-certification page puts the onus on whoever makes the origin declaration to know the rules and certify that the goods meet them. It also says importing authorities may raise a verification request if they doubt the goods' originating status.
So if the buyer is claiming under the EU-Singapore FTA, the UK-Singapore FTA or SAFTA with Australia, don't wait for a certificate from Singapore Customs: the self-certification page says it doesn't issue preferential certificates under those agreements. An Australian buyer claiming under AANZFTA or RCEP is a different case, so check which agreement they mean. The exporter, producer or importer declares origin, as each agreement specifies, and whoever signs carries the onus.
Can the route or the invoice undo origin?
Yes, and exporters skip this check because it isn't about the product. The handbook's direct consignment rule says the good must be transported directly to the importing party to keep its originating status. Transit through a non-party can still work if three things hold: it's justified as a transport requirement, the goods don't enter commerce there, and nothing happens to them but loading and unloading. Some agreements also want documents proving it (PCO handbook).
The handbook flags one more trap under RCEP. Seven parties apply tariff differentials: different rates for the same good, depending on which RCEP country it originates from. Those seven are China, Indonesia, Japan, the Philippines, South Korea, Thailand and Viet Nam. Exporters are told to check whether their goods are affected and to consider whether another FTA may be more beneficial.
If you're quoting under RCEP into one of those seven markets, compare RCEP with the other agreements that cover that market first.
Can anyone confirm origin before you sign the contract?
Not from Singapore Customs, for an export. Customs does issue origin rulings, but its page limits them to goods imported into Singapore. For goods bound for other countries, it sends you to the importing country's customs authority for advice (Customs, origin rulings).
What Customs does offer exporters is a self-check: the FTA Cost Statement Calculator, which Customs describes as a preliminary check of a manufactured good's value content and/or tariff-shift status under one specific FTA, once you have identified the origin criterion for that good (Customs, Origin Documentation Overview). Asked how to calculate local content, AskGov points to the legal text of the specific FTA or the preferential-CO handbook (AskGov).
A preliminary assessment is just that. If the buyer needs more before signing, the pages we read point to one place: the customs authority of the importing country.
What we'd tell the buyer, situation by situation
This table sets the Customs pages above against six common situations. The right-hand column is our reading of what they mean for a quote. It isn't a Customs ruling or an origin assessment of your goods.
Your situation | What the Customs pages say | What it means for the quote |
You buy finished goods overseas and resell them from Singapore unchanged | Minimal processing doesn't confer origin. A back-to-back preferential CO needs the import into Singapore covered by a preferential CO from the first exporting country, and no further processing here. | Don't quote Singapore origin. Ask your supplier whether the goods arrive on a preferential certificate that a back-to-back one could follow. |
You repack, relabel or make up sets in Singapore | Packing, labelling and making up sets are listed as simple or minimal processes. | Treat the goods as not Singapore-originating unless a further process changes that. |
You manufacture in Singapore with imported materials | Origin depends on the rule for your HS code: tariff shift, value content or process. | Quote the duty outcome only after the calculator check against that rule. Until then, say it's being checked. |
Some materials come from another party to the same FTA | Accumulation can count them, but only with proof such as that party's preferential certificate. | Get the supplier's certificate first; without it, work with the lower figure. |
The buyer claims under the EU-Singapore, UK-Singapore or Singapore-Australia (SAFTA) agreement | These agreements run on self-certification; Customs won't issue a PCO under the EU agreement. | Agree who makes the origin declaration. That party carries the onus. |
The buyer only needs proof of where the goods were made | An ordinary CO does not entitle the goods to preferential treatment. | Don't promise any duty saving; an ordinary CO may be all they need. |
One pattern runs through the table. A risky promise is made from a product description; a safe one is made from a bill of materials, a rule reference and a named agreement.
Our Certificate of Origin guide makes the same point from the other end. When the buyer isn't claiming FTA treatment at all, skip the preferential route entirely, and get that confirmed by the buyer in writing.

Six checks before you promise FTA duty treatment
Get the agreement and the product code in writing. Ask the buyer which FTA their customs will apply, and agree the HS code of the finished product. That code is how the rule you need is listed.
Check coverage and the rate in Tariff Finder. Confirm the product is covered, compare the preferential rate with the basic (MFN) rate, and compare agreements if more than one applies. GST and excise aren't part of the preference.
Read the product-specific rule. Note whether it asks for a change of chapter, heading or sub-heading, a value-content percentage, a process, or a combination.
Build the material list. For every input, record the supplier, country, HS code and value. Anything whose origin you can't establish counts as non-originating. Ask suppliers for declarations now, not after the order.
Run the FTA Cost Statement Calculator. Use it as Customs describes it: a preliminary assessment. Apply de minimis or accumulation only where the agreement allows it and you hold the proof.
Check the proof and the route. Who issues the proof under that agreement: Customs, an approved exporter, or a self-declaration? Are a manufacturer registration and a cost statement needed first? The handbook says the cost statement goes to Customs unless the agreement runs on self-certification. Does the shipping route keep the goods directly consigned?
The objection to expect runs like this: "We're a registered manufacturer and our goods already qualify under another agreement, so this one will too." AskGov answers it directly. Each FTA has its own origin criteria, and being a registered manufacturer with Singapore Customs doesn't by itself make a good originating under RCEP (AskGov).
A past certificate proves the rule was met once, under one agreement. It says nothing about the next one.
If your buyer's customs has already sent a certificate back, that's a different job. See our guide to fixing Certificate of Origin mistakes.
Origin is only half the paperwork. The export still needs its permit; our guides to customs clearance in Singapore and getting a cargo clearance permit cover that side.

Frequently asked questions
What are the rules of origin in Singapore?
Singapore applies two sets, according to the Customs overview. Non-preferential rules decide the country of origin on permits and ordinary COs: wholly obtained, 25% local content, a 6-digit tariff shift, or a chemical reaction for Chapters 27 to 40. Preferential rules come from each FTA and decide whether the buyer gets a lower duty rate.
Is the 25% local content rule enough for FTA duty treatment?
No. The 25% local content test is part of Singapore's non-preferential rules, which also govern the ordinary Certificate of Origin. Preferential treatment needs the criteria of the specific FTA, such as the 40% value content or tariff-shift rules the Customs handbook lists as general rules under several ASEAN agreements.
Does registering as a manufacturer mean our goods qualify under every FTA?
No. AskGov says being a registered manufacturer with Singapore Customs doesn't by itself make a good originating under RCEP, because each FTA has its own origin criteria. The product still has to meet the rule in that agreement's rules of origin chapter and annexes.
Why does the buyer still pay GST with a preferential certificate?
Because a preferential certificate only affects customs duty. AskGov states that GST and excise duty fall outside the agreement's scope and remain applicable. It also says some goods are excluded from preferential treatment under an FTA, and in that case the certificate serves no purpose.
Can Singapore Customs confirm our export's origin in advance?
Not for an export. Singapore Customs limits its origin rulings to goods imported into Singapore. For goods going to other countries, it directs you to the customs authority of the importing country. Customs' calculator gives exporters a preliminary self-assessment, not a ruling.
Can goods bought overseas and re-exported from Singapore get FTA rates?
Sometimes, through a back-to-back preferential CO. AskGov lists the conditions, including an FTA with a back-to-back provision, an import into Singapore covered by the first country's preferential CO, and no further processing here. Singapore Customs also says it can't issue a CO for goods not exported from Singapore.
