Scope, customers and value-added work
The fifth edition published 30 January 2026 covers section 33 B/regulation 42 B recovery where a registered supplier sends customers’ goods abroad for contracted value-added work and re-imports them. Work includes testing, repair, assembly, fabrication, manufacturing and refining; logistics, leasing and similar services are excluded. Customers are local persons or overseas persons normally GST-registered, excluding OVR pay-only. A local customer has Singapore-only business/fixed establishment, is legally constituted in Singapore without an establishment anywhere, or has a Singapore establishment most directly concerned with the particular supply. Business establishment includes headquarters, branch or agency; fixed establishment needs permanent technical and human resources.
Contractual chain and goods movement
The customer consigns goods under a contract with you; you instruct and contract with an overseas facility, subsidiary or subcontractor, which invoices you. You re-import after processing, possibly doing further work before/after, then deliver to the customer or its instructed destination and invoice your own contracted work. Overseas processing alone does not prove an export sale of your service or give input entitlement; control, contract scope and onward taxable supply must remain aligned.
All seven conditions for full recovery
Re-import within six months of sending abroad; longer periods require prior written Comptroller approval. Retain oversight/control from customer consignment through final delivery. Do not receive reimbursement of import GST. All overseas work and new goods must follow your instructions and agreed customer contract. Make an onward taxable supply before business cessation or deregistration, whichever first. Hold the payment/import permit in your own importer-of-record name. Comply with additional restrictions imposed case-by-case or generally. Physical location abroad does not defeat control if you retain oversight.
Approved suspension/deferment schemes
Qualifying MES, IGDS, ACMT Contract Manufacturer and ARCS Approved Refiner privileges can be used with the claimant as importer of record. This is not a general extension to Approved Third Party Logistics. AISS already separately permits certain customers’ aircraft-part imports; apply its own guide. Suspension and IGDS deferment have different return sections and should not be collapsed into one identical Box 9 procedure.
Examples 1–2: assembly/coating and new-goods fabrication
Example 1 combines Singapore assembly with Thailand coating, then returns locally: full re-import tax claim if conditions hold; the customer supply is standard-rated. Example 2 sends local customer B’s semi-finished goods to Penang, with new goods and fabrication both contracted through you, then re-imports and exports to B’s Korean affiliate. Full claim is possible. If processing produces new/different goods by changing nature/character, your onward supply is goods and can be zero-rated on export with evidence; otherwise it is a service requiring its own zero-rating test.
Example 3: progressive testing payments follow final contracted delivery
An overseas normal-registered customer C pays S$10,000 for Singapore Test 1 and S$20,000 after Korean Test 2, verification and delivery. Re-import tax can be fully claimed. Export of completed tested goods permits the whole S$30,000 service to qualify under 21(3)(g), including both instalments. If final delivery is local, the whole S$30,000 is standard-rated; do not zero-rate the first S$10,000 merely because goods temporarily left for Test 2. The integrated contract is completed on final delivery.
Example 4: direct customer instruction for new goods prevents full claim
A Batam subcontractor adds new goods on customer D’s direct instructions, invoices D for those goods and you only for fabrication, then goods are re-imported and sent to Japan. Your contract did not include the new goods, so the full recovery condition fails despite your permit. The Comptroller may approve a reasonable-proxy partial claim attributable to your own value-added supply case-by-case, with the permit in your name. It is not an automatic fraction elected by the business.
Example 5: later reimbursement reverses the benefit
Failure of any condition after claiming or suspending tax requires repayment via output Box 6 in the first-failure period, with incorrect-return penalties possible. Example 5 overseas E’s goods undergo Japan work, re-import and further Singapore testing, then shipment to India. A full claim originally made must be repaid when E later reimburses the import GST, in the period of reimbursement. This rule applies even though processing and export otherwise qualified.
Example 6: cessation or deregistration before taxable completion
The law-backed rule requires the contracted taxable supply before cessation/deregistration. Customer F’s materials processed partly in China qualify if manufacturing completes and invoice/payment occurs while still registered. Deregistering before completion so the later supply is not taxable breaks the condition and requires repayment of prior import input. Report output Box 6 in the cessation-period return or F 8 on deregistration.
Return boxes and all five document groups
Report goods removed overseas in Box 2 with export evidence as this guide directs. Re-import payments use Box 5 goods and Box 7 input in the import-date period. Approved suspension imports report Box 5 plus approved-scheme Box 9; IGDS additionally uses its specific goods/deferred-tax section. Retain customer contracts/orders/instructions; subcontractor contracts/orders/instructions; original export documents; re-import permits/support naming you; and your customer tax invoice plus final export/delivery documents. These reporting/record requirements are expressly given legal force.
Other overseas customers and historical revisions
For unregistered overseas customers, import recovery is instead subject to section 33 A/regulation 42 A and the Imports guide; do not force them into 33 B’s customer definition. Enquiries go through IRAS GST Contact Us. Revisions cover 2016 establishment/AISS,2019 exclusion of OVR pay-only and 2022 extension of OVR to remote services/LVG. The 2026 cover’s fifth-edition date does not create additional listed substantive amendments beyond the displayed log, which ends 2022.
