Examine how social security agreements like the Double Contribution Convention address non-tariff barriers to trade in services.

Trade in services is obstructed less by tariffs than by regulatory frictions — visa caps, qualification recognition and, critically, mandatory host-country social security contributions that Indian professionals pay without ever drawing benefits. The India-UK Double Contribution Convention (DCC), in force alongside CETA from 15 July 2026 [1], illustrates how such agreements dismantle these behind-the-border barriers.

How social security contributions act as a non-tariff barrier

• Short-term deputees under Mode 4 (movement of natural persons) contribute to the host system, yet minimum vesting periods mean the contribution is forfeited — a pure sunk cost.
• This functions as a hidden cost escalator on service exports, raising the effective price of Indian IT and professional services and eroding competitiveness against local suppliers.
• The burden falls hardest on MSME service exporters, for whom the outlay is not absorbable at scale.

Mechanisms through which SSAs remove the barrier

• Detachment: a Certificate of Coverage exempts the deputee from host contributions while remaining covered at home [3]. The DCC extends this exemption from 3 to 5 years, matching real project cycles [1].
• Totalisation of service periods across countries and exportability of pension protect long-term entitlement [3].
• Equality of treatment removes discriminatory regulatory application.

Assessment of impact and limits

• Over 75,000 Indian professionals and 900+ employers are covered, with industry estimates of savings exceeding USD 600 million annually [1][2].
• Yet SSAs are partial remedies: they do not touch visa quotas, wage-parity conditions or professional-qualification recognition, which remain the binding constraints on Mode 4.
• Coverage is also bilateral and uneven, leaving Indian workers in non-SSA destinations exposed.

Social security agreements thus convert an invisible fiscal levy into a neutral, reciprocal arrangement, making services liberalisation commercially meaningful rather than merely notional. Embedding DCC-type instruments in every future FTA — while simultaneously negotiating mutual recognition of qualifications — would let India translate its demographic and skills advantage into durable services export leadership, advancing the SDG-8 goal of decent work and productive employment.
