Twelve Questions to Ask Before You Pick a Flavour Supplier in Asia

The test that separates flavour suppliers in Singapore is documentary, not commercial. Singapore does not permit flavourings from a positive list: regulation 22(1) of the Food Regulations defines a flavouring agent as “In these Regulations, “flavouring agent” means any wholesome substance that when added or applied to food is capable of imparting taste or odour, or both, to a food.”, so there is no product register to check a supplier against. What the regulation does bind hard is the carrier and a blacklist, and the two documents that prove a supplier has cleared both are the ones buyers most often forget to ask for. The twelve questions below are written to Singapore law: Malaysia, Indonesia and Thailand each set their own flavouring rules and run their own halal schemes, so a supplier cleared here is not cleared there by default, and our guide to halal flavour certification covers that side.

What Regulation 22 Actually Binds

Because the definition is functional, compliance is judged on what a flavouring contains rather than on whether it appears on an approved list. Two provisions do the real work. Regulation 22(2) closes the list of solvents a flavouring essence may be supplied in: “No person shall import, sell, advertise, manufacture, consign or deliver any natural or synthetic flavouring essence or extract which is contained in a solvent other than a permitted solvent, namely, 1,3‑propanediol, benzyl alcohol, beta-cyclodextrin, diacetin, diethyl ether, ethyl acetate, ethyl alcohol, glycerol, isopropyl alcohol, propylene glycol, triacetin and water.” Twelve are named and nothing else qualifies. Regulation 22(3) then sets the grade: “The permitted solvents referred to in paragraph (2) other than water shall conform with the British Pharmacopoeia standard.”

The Sixteen Substances That Are Prohibited Outright

The second provision is a flat prohibition. Regulation 22(7) states that “The use of coumarin, tonka bean, safrole, sassafras oil, dihydrosafrole, isosafrole, agaric acid, nitrobenzene, dulcamara, pennyroyal oil, oil of tansy, rue oil, birch tar oil, cade oil, volatile bitter almond oil containing hydrocyanic acid and male fern as flavouring agents is prohibited.” These are not capped at a maximum level, they are forbidden, and regulation 22(10) carries the ban through to material supplied for factory use: “No person shall import, sell, advertise, manufacture, expose or offer for sale, consign or deliver with a view to it being used in the preparation of food for human consumption, any synthetic flavouring essence or extract which contains any of the prohibited substances specified in paragraph (7).” A supplier working to a European or American specification may be applying a parts-per-million limit for coumarin or safrole that Singapore does not recognise.

What SFA Says It Will Accept

What positively justifies a flavouring substance, SFA has answered in writing. Its guidance on permitted food additives states that “In principle, SFA has no objection to the use of flavouring substances that have been evaluated and endorsed by recognised international bodies such as the Joint FAO/WHO Expert Committee on Food Additives (JECFA), the Flavour and Extract Manufacturers’ Association (FEMA), or the European Food Safety Authority (EFSA), under good manufacturing practice (GMP), provided that the flavouring preparations do not contain any of the prohibited substances listed under Regulation 22(7) of the Food Regulations.” That is an accommodation routing acceptance through three named evaluating bodies and back to the reg 22(7) blacklist, not a register of approved products, and SFA says of the document itself that “This guidance document is not legally binding, and should be read together with the Food Regulations.”

The Purity Default: JECFA Unless Stated

Purity has its own default. Regulation 15(4) provides that “No person shall import, sell, advertise, manufacture, consign or deliver any permitted food additive unless the purity of that food additive conforms with the specifications as provided in this Part. Where it is not so provided, the purity of the permitted food additive shall conform with the specifications as recommended by the Joint Food and Agriculture Organisation of the United Nations and World Health Organisation (FAO/WHO) Expert Committee on food additives.” So where the Regulations are silent, the JECFA specification is the standard your supplier's certificate of analysis has to meet, and a specification sheet that names no purity standard at all is naming JECFA by omission.

Do Not Confuse Flavourings With Flavour Enhancers

One distinction is worth fixing before the questions start. Flavour enhancers are regulated separately under regulation 23, which is a closed list: regulation 23(5) forbids any food containing a flavour enhancer other than one specified there, and regulation 22 contains no equivalent provision. A supplier who answers a flavouring question with an enhancer permission has not read the right clause.

Q1: Name the Solvent System Against Reg 22(2)

Ask which solvent or carrier system each product uses, against regulation 22(2) by name. This is the single most useful document in Singapore and it is rarely volunteered: one page naming the solvent system, confirming every component sits within the twelve, and confirming British Pharmacopoeia grade for everything but water. A supplier who cannot produce it cannot show the material is lawful to sell here.

Q2: Get the Reg 22(7) Declaration in Writing

Ask for a written statement that no substance prohibited by regulation 22(7) is present in any product supplied. Sixteen substances, named, with no permitted level. A buyer holding that statement has evidence on the one thing Singapore prohibits outright; a buyer without it is relying on the supplier having read a regulation their home market does not apply.

Q3 and Q4: Evaluation Basis and Purity Standard

Ask which safety evaluation the supplier relies on for each flavouring substance, and expect JECFA, FEMA or EFSA by name. That is the basis on which SFA states it has no objection, so the reference is the supplier's justification and therefore yours. Ask separately for the purity specification.

Q5: How Will This Be Declared on My Label?

Ask how each product should be declared on your finished label, in the supplier's own words, before you formulate. The First Schedule to the Food Regulations permits a flavouring to be declared by a generic term qualified by the words natural, nature identical or artificial where one of them applies; item 11 is quoted in full in our guide to Singapore flavour labelling. The qualifier is tied to real definitions. Regulation 22(6) provides that “Natural flavouring essences or extracts shall be preparations in any permitted solvent or any combination of permitted solvents, with or without sweeteners other than sweetening agents, permitted colouring matter or chemical preservatives, of sapid or odoriferous principles, or both, derived from a plant after which the flavouring extract or essence is named.”, so “natural” attaches to the plant the essence is named after, while regulation 22(9) defines the synthetic side by origin: “Synthetic flavouring essences or extracts shall include any artificial flavour or imitation flavour which may resemble the sapid or odoriferous principles of an aromatic plant, fruit or vegetable or any other food, except that the flavouring principle shall be derived in whole, or in part, from either chemical synthesis or any other sources that does not involve extraction or isolation therefrom of the sapid or odoriferous principles present in an aromatic plant, fruit or vegetable or any other food.”

Q6: The Allergen Statement Is Now Your Evidence

Ask for an allergen declaration covering all eight Singapore classes, with any carry-over quantified. Regulation 5(4)(ea) lists “the following foods and ingredients that are known to cause hypersensitivity: (i) cereals containing gluten, i.e. wheat, rye, barley, oats, spelt or their hybridised strains and their products; (ii) crustacea and crustacean products; (iii) eggs and egg products; (iv) fish and fish products; (v) peanuts, soybeans and their products; (vi) milk and milk products (including lactose); (vii) tree nuts and nut products; and (viii) sulphites in concentrations of 10 mg/kg or more”. Regulation 5(4)(b)(vii), inserted with effect from 30 January 2026, now states expressly that where such a food or ingredient is carried over from an ingredient into a finished food product it must be specified by its appropriate designation and not by the First Schedule generic term; the clause is set out word for word in our guide to Singapore flavour labelling. Your supplier's allergen statement is compliance evidence for your label.

Q7: Which Additives Travel With the Flavouring?

Ask for the composition breakdown that identifies any food additive inside the flavouring. Regulation 5(4)(b)(vi) provides that “where any food additive is carried over from an ingredient into a finished food product”, and then applies a functional test: “(A) where the food additive is in an amount sufficient to perform a technological function in that product, the food additive must be specified by its appropriate designation; and (B) to avoid doubt, where the food additive is in an amount that is not sufficient to perform any technological function in that product, the food additive need not be specified” You cannot run that test on a flavouring whose additive content you have not been told.

Q8 and Q9: Batch Traceability and Origin

Ask for batch-level traceability and a statement on biotechnology. Regulation 5(4)(da) now requires your label to carry “an identification number or mark (like a lot number, batch number or serial number) that identifies the producing factory and production lot of the food”, traceable only through supplier batch records, so a certificate of analysis per batch carrying a lot identifier is the practical answer. Regulation 5(4)(eb) separately requires declaration of “in any food or food ingredient obtained through biotechnology, the presence of any allergen transferred from a food or an ingredient mentioned in sub‑paragraph (ea)”, which needs an origin statement rather than an assumption.

Q10: Which SFA Licence, and What Number?

Ask which SFA licence or registration the supplier holds, with the reference number. Section 21 of the Sale of Food Act 1973 provides that “A person must not carry on a non‑retail food business except in accordance with a licence issued to the person by the Director‑General under this Part.” Section 2F(2) does not name flavour compounding in its list of non-retail food businesses; the closest express analogues are the processing or packing of herbs and spices, and the manufacture of dry mix products by blending and packing, so confirm the classification with SFA rather than assuming it. On the import side the instrument is the Registration to Import Processed Food Products and Food Appliances, which SFA lists as free with a one working day processing time; its own pages disagree on how long that registration lasts, so check any stated validity with SFA rather than accepting it.

Q11: Which MUIS Scheme, and Verify It

Ask which MUIS halal scheme the certificate is issued under, because the schemes cover different things. MUIS describes the Product Scheme as “Product Scheme: Issued to products which are manufactured or partly manufactured/processed in Singapore.” and the Whole Plant Scheme as “Whole Plant Scheme: Issued to manufacturing facilities and all products manufactured therein.” Treating a product certificate as plant-wide is a common buyer error. For imported material the relevant scheme is Endorsement, “Issued to imported, exported or re-exported products in respect of which Halal certificates have been issued.” Certificates are time limited: MUIS states “Receive Halal Certificate (Valid for 1 or 2 years)” without saying which schemes get which, so read the expiry rather than assuming a term, and verify the certificate at MUIS's own establishment directory rather than accepting a PDF.

Q12: Hygiene, Micro Criteria and Dosing Discipline

Ask for the hygiene and microbiological position. Codex CAC/GL 66-2008 defines flavourings as “Flavourings are products that are added to food to impart, modify, or enhance the flavour of food (with the exception of flavour enhancers considered as food additives under the Codex Class Names and the International Numbering System for Food Additives - CAC/GL 36-1989). Flavourings do not include substances that have an exclusively sweet, sour, or salty taste (e.g. sugar, vinegar, and table salt). Flavourings may consist of flavouring substances, natural flavouring complexes, thermal process flavourings or smoke flavourings and mixtures of them and may contain non-flavouring food ingredients (Section 2.3) within the conditions as referred to in 3.5. They are not intended to be consumed as such.”, routes their hygiene to the general principles of food hygiene and their microbiological criteria to the Codex microbiological guidelines, and sets the dosing discipline: “Flavourings should be used under conditions of good manufacturing practice, which includes limiting the quantity used in food to the lowest level necessary to accomplish the desired flavouring effect.” Those pointers are the textual basis for asking a supplier for a HACCP position and micro specifications, rather than for treating both as optional extras.

Malaysia's 2027 Gate, and Vietnam's Suspended Decree

Two 2026 instruments shape supplier diligence in this region, and neither is a Singapore rule. Malaysia gazetted the Food (Amendment) (No. 3) Regulations 2026, P.U. (A) 298, on 26 August 2026, in operation 1 March 2027. Its new Part IIB makes a food-safety assurance programme recognised by the Ministry of Health Malaysia's Food Safety and Quality Programme a precondition of importing, advertising or selling imported food there, and the programme has to be running at the overseas manufacturing premises, not at the importer. So the question to put to a supplier now is which scheme its plant operates and whether Malaysia recognises that scheme, because the answer takes longer to fix than the lead time on a purchase order. Vietnam is the second market to watch, and today it is not a gate at all: Nghị định 46/2026/NĐ-CP was signed on 26 January 2026, suspended by Nghị quyết 09/2026/NQ-CP on 4 February 2026, restored briefly, then suspended again by Nghị quyết 15/2026/NQ-CP of 6 April 2026 until the amended Food Safety Law and its guiding decree take effect. Nghị định 15/2018/NĐ-CP continues to govern registration, self-declaration and imported-food checks, so ask which decree your importer's dossier is written to rather than assuming the newer number applies.

Questions Worth Asking Now

One more question is worth asking now even though nothing has been decided. On 11 August 2026 the United States FDA proposed to convert its voluntary GRAS notification programme into a mandatory one, with comments open until 9 December 2026, and its own impact analysis counts 1,740 association-expert-panel GRAS substances inside the scope, the category that holds FEMA-evaluated flavourings. It is a proposed rule and nothing is in force. What makes it a procurement question rather than a news item is the streamlined route the proposal contains, which would be available for one year only after any final rule takes effect. A supplier who has never thought about whether its US-bound substances are notified or self-determined will not be able to answer that in the month it opens. Separately, the practical international currency for a flavouring permission is still FEMA GRAS: the Australia New Zealand Food Standards Code moved its reference edition from 30 to 31 on 30 April 2026, so a supplier writing compliance statements against edition 30 is writing them against a superseded reference. Neither of these changes anything SFA requires.

Two Claims to Treat With Caution

Check any suggestion that an individual flavouring product has been approved or registered by SFA: SFA licenses businesses and registers importers of processed food, and its additive guidance is expressly not legally binding, so no product-level approval exists to hold. Check any dollar figure or growth rate quoted for the Singapore flavour industry against its source.

Who Owns Your Supplier in 2026

Two ownership changes sit behind supplier choices being made this year, and both are agreed rather than done. IFF is selling its Food Ingredients business to funds advised by CVC. That perimeter is “texturants, emulsifiers, plant-based solutions, and other specialty ingredients”, and IFF names “Taste, Scent, and Health & Biosciences” as the businesses it is keeping, so its flavour arm is not in the sale; the transaction is “expected to close by the end of the second quarter of 2027”. Ingredion has not acquired Tate & Lyle either. Tate & Lyle shareholders approved the scheme on 28 July 2026, but the company states the scheme is “expected to become Effective during the second half of 2027” and remains subject to the “Material Antitrust Conditions”. If a continuity or change-of-control clause in your supply agreement turns on who owns the counterparty, both dates are 2027, not 2026.
