That activity might include local production, investment, training, subcontracting or access to technology. For example, a government buying aircraft might require the supplier to arrange work for domestic firms or license them to manufacture specified components. Such commitments may build local capability, but a promise to transfer technology is not proof that the recipient has absorbed it or that the wider economy benefits.
What is a defence offset?
The World Trade Organization’s Agreement on Government Procurement (GPA) defines an offset as a condition or undertaking that encourages local development or improves a party’s balance-of-payments accounts. Its examples include domestic content, technology licensing, investment and counter-trade. In defence trade, the U.S. Department of Commerce’s Bureau of Industry and Security (BIS) describes offsets as industrial compensation arrangements that a foreign government requires as a condition of buying defence articles or services from a non-domestic source.
The term covers different activities in different legal and reporting systems. An offset may be required by a government, negotiated into a contract, or connected to a defence sale in another way. The precise meaning, eligible activities and obligations depend on the applicable rules and agreement.
What can an offset include?
BIS lists several types of activity in its U.S. defence-trade reporting guidance. These categories are useful examples, not a universal taxonomy for every country.

- Co-production: production shared between parties, potentially under a government-to-government arrangement.
- Licensed production: a firm receives permission to manufacture a product or component using licensed technology.
- Subcontracting: the foreign supplier places work with local companies.
- Technology transfer: knowledge, technical information or rights are provided to support local industrial activity.
- Training: personnel receive instruction or practical preparation connected with the relevant activity.
- Purchases, investment or credit assistance: other commercial or financial arrangements intended to support local activity.
These arrangements are not interchangeable. BIS guidance, for example, distinguishes co-production from licensed production in its reporting categories. A government-to-government arrangement authorizing technology transfer needed to manufacture a U.S.-origin defence article may be classified as co-production. If that transfer is not specifically addressed in the relevant Letter of Offer and Acceptance, the activity may instead be classified as licensed production. That distinction concerns the U.S. reporting framework; it should not be assumed to settle classification under another country’s rules.
How does technology transfer work in a defence offset?
Technology transfer is an agreed or required part of some industrial arrangements, but the phrase can cover very different things. A licence to manufacture a component, technical information, training, or production know-how may each support local work without giving the recipient the same capabilities as the original developer. The contract and applicable controls determine what is actually provided and what the recipient is permitted to do with it.
It is also important to distinguish an ordinary voluntary licence or mutually agreed industrial partnership from a transfer demanded as the price of access to a market or procurement. The OECD’s procurement analysis describes a blurred boundary: pressure to transfer technology may be implicit, and private or behind-closed-doors agreements can make cases difficult to identify. It concludes that “Identifying cases of forced technology transfer is complex.”
For any particular arrangement, useful questions include what technical knowledge or rights are included, who may use them, whether the recipient can develop or produce independently, and what limits apply to onward transfer or end use. Intellectual-property terms and export-control requirements matter alongside the offset commitment itself.

The WTO GPA does not create a single worldwide rule for every defence purchase. It applies to procurement within its coverage, which depends on the agreement, the relevant party’s schedules, the procuring entity and the procurement in question.
For covered procurement, Article IV.6 says that a party and its procuring entities “shall not seek, take account of, impose or enforce any offset.” Article III.1, however, says the agreement does not prevent a party from taking action or withholding information it considers necessary to protect essential security interests relating to the procurement of arms, ammunition or war materials, or procurement indispensable for national security or defence.
That security language is not a blanket statement that all defence contracts are outside the GPA. Whether a procurement is covered and whether a particular security measure is available are legal and factual questions. The GPA’s earlier 1994 text included a developing-country accession provision concerning specified offsets; that historical provision should not be treated as a universal present-day exception. Current applicability requires checking the amended agreement and the relevant party’s schedules.
How does the United States handle defence offsets?
The United States provides a specific example, not a template for other countries. U.S. Code §4852 directs the President to establish a comprehensive policy for offset arrangements associated with foreign purchases of defence equipment or supplies. It addresses technology transfers and their potential effects on U.S. industrial subsectors.
The statute restricts a U.S. official from entering an agreement requiring a technology transfer in connection with an offset when the transfer would significantly and adversely affect the U.S. defence industrial base and cause substantial financial loss to a U.S. firm. It provides an exception if the Secretary of Defense, consulting the Secretaries of Commerce and State, determines that the transfer strengthens U.S. national security and certifies that determination to Congress.

BIS reporting
BIS collects annual offset data from U.S. firms with associated offset agreements and reports to Congress on the impact of offsets in defence trade. Its page lists the Twenty-eighth Report to Congress, dated May 2024, as the latest report shown there.
BIS guidance says U.S. firms must report qualifying offset agreements exceeding $5 million in value and offset transactions for which at least $250,000 of offset credit has been claimed. It gives June 15 of the following year as the deadline for reporting new contracts and transactions in the described categories. These are U.S.-specific reporting requirements. Firms relying on them for compliance should verify the current regulation and their own reporting responsibility.
Export controls still apply
An item offered as part of an offset may require an export licence, but not every offset does. The applicable requirements depend on such factors as the item’s classification, destination and end use. BIS advises consulting Commerce, War and State for policy guidance before offering items controlled for reasons such as Missile Technology.

Why do governments seek offsets, and what are the risks?
Governments may seek offsets to ease the domestic economic burden of a large defence purchase, preserve or increase employment, obtain technology, or promote particular industrial sectors. These are policy objectives, not evidence that a specific offset has achieved them.
Technology access may help domestic firms develop capabilities. But a transfer that gives local competitors access to knowledge or technology without bearing the original research-and-development costs can raise competition concerns. It can also create risks for the supplier’s intellectual property, its industrial base, and compliance with export controls. The OECD warns that forced transfers can undermine fair competition and that implicit pressure can be hard to document.
The central trade-off is therefore not simply “local production versus imports.” It is whether the terms create useful, sustainable capability without imposing costs or risks that outweigh it—and whether the promised transfer can legally and practically be delivered.
Do defence offsets benefit the local defence industry?
Not necessarily. A contract can record a commitment, transaction or credit without showing that domestic firms have gained lasting technical capability, productive work or durable employment. The sources cited here establish common offset activities and policy aims, but do not provide a causal estimate showing that offsets reliably produce lasting industrial benefits or net economic gains.
To assess a particular programme, look beyond the value assigned to offset commitments. Relevant evidence would include whether local firms can use the knowledge after the contract, whether production or technical capability continues, and whether the work improves productivity or supports sustained skilled employment. Those outcomes should be weighed against costs to the buyer, effects on competition, intellectual-property risks and any export-control constraints. Without outcome evidence, the existence or reported value of an offset is an input—not a verdict on its success.
