WTO SPS Agreement

In scope terms the agreement applies to measures a member takes to protect human, animal, or plant life or health from risks arising from pests, diseases, additives, contaminants, toxins, and disease-carrying organisms in food, beverages, feedstuffs, plants, and animals. Its disciplines run broadly along these lines: measures should rest on scientific principles and evidence and be based on an assessment of risk; they should be applied only to the extent necessary and should not arbitrarily or unjustifiably discriminate between members where similar conditions prevail; and members should notify measures and make them transparent.

Three further concepts do a great deal of work. Harmonisation encourages members to base measures on international standards. Equivalence requires a member to accept another member’s different measures if they achieve the same level of protection — different route, same destination. Regionalisation requires measures to be adapted to the conditions of the area a good comes from rather than the country as a whole, which is what makes pest free areas and disease-free zones tradeable concepts rather than academic ones.

The agreement’s most far-reaching effect is indirect. Rather than write health standards itself, it names three existing international standard-setting bodies as the reference for their domains: the Codex Alimentarius Commission for food safety, the International Plant Protection Convention for plant health, and the World Organisation for Animal Health for animal health. A member whose measures conform to the relevant international standard enjoys a presumption of consistency with the agreement.

This single move transformed three sets of voluntary technical texts into the benchmarks of world agricultural trade. None of them became law — Codex still binds nobody, an ISPM still regulates nothing — but a member departing upward from them may be asked to justify the departure scientifically in a dispute. That is why negotiations in those bodies are contested, and why "Codex is voluntary" and "Codex is consequential" are both true at once.

The agreement is an obligation between states. It binds WTO members in their conduct towards one another, and it is enforced through dispute settlement brought by one member against another. A trader cannot invoke it, cannot sue under it, and cannot rely on it when a consignment is refused. An exporter facing an import measure they consider unjustified has no standing under the agreement; the only route is to persuade their own government to take the matter up, which is slow, political, and rarely proportionate to one shipment.

For anyone actually moving goods, therefore, the agreement is context rather than a tool. The operative rules remain the importing country’s measures as they stand today. The agreement may shape those measures over years through disputes, notifications, and negotiation, but it does nothing for a consignment at a border this week. Reading it as a source of rights for traders is the most common error made about it.

• No health standards — no limits, pest requirements, hygiene rules, or disease provisions of its own
• Not quality, labelling, or technical requirements generally — those fall under the TBT Agreement
• Not tariffs, valuation, or origin — separate agreements govern those
• No rights for traders — it binds members and is enforced between members
• Not a source of admissibility — the importing country’s measures govern a consignment

The boundary with the TBT Agreement is the one most worth holding onto. If a measure protects health from the specific risks the SPS Agreement lists, it is an SPS measure. If it is a technical requirement about a product for some other purpose — labelling, quality, terminology, packaging — it falls under TBT instead. The same subject matter can produce measures of both kinds, and which agreement applies turns on the objective of the measure rather than on its form.
