--- title: "Trade Policy" description: "Six-tab trade-policy surface covering restrictions, tariff trends, trade flows, non-tariff barriers, US customs revenue, and bilateral Comtrade flows." --- The **Trade Policy** panel (internal id `trade-policy`) is the dashboard's go-to surface for live trade-policy context — what's getting restricted, where tariffs are moving, how flows are shifting, what barriers exist, and how US customs revenue is tracking as a real-time signal of tariff pass-through. ## What the panel shows Six tabs across one data-dense panel (`defaultRowSpan: 2`): | Tab id | Shows | |---|---| | `restrictions` | Active trade restrictions — the default tab on mount. | | `tariffs` | Tariff trends (`TariffDataPoint[]`) and `EffectiveTariffRate` series. | | `flows` | Bilateral trade flows — `GetTradeFlowsResponse`. | | `barriers` | Non-tariff barriers — `GetTradeBarriersResponse`. | | `revenue` | US Treasury customs revenue — monthly data with FYTD year-over-year comparison and spike highlighting. | | `comtrade` | Full Comtrade bilateral flow search — `ListComtradeFlowsResponse`. | `TabId` is the union `'restrictions' | 'tariffs' | 'flows' | 'barriers' | 'revenue' | 'comtrade'` (`src/components/TradePolicyPanel.ts:17`). Panel id is `trade-policy`; canonical component is `src/components/TradePolicyPanel.ts`. Title resolves from i18n (`panels.tradePolicy`). ## How you reach it - **Cmd+K**: type *trade*, *tariff*, or *customs*. - **Availability by variant**: registered and enabled by default in the **full/geopolitical** (`priority: 1`), **finance** (`priority: 1`), and **commodity** (`priority: 1`) variants. Not present in the tech or happy variants. Source: `'trade-policy'` entries in `FULL_PANELS`, `FINANCE_PANELS`, `COMMODITY_PANELS` of `src/config/panels.ts`. ## Data sources Six response shapes from `@/services/trade`, each backed by a generated sebuf REST RPC in `TradeService`. The panel shell is free; tariff trends and Comtrade calls use `premiumFetch` because those two paths are premium transport paths, while restrictions, flows, barriers, and customs revenue use the public client. Customs revenue also checks the bootstrap cache key `customsRevenue` before falling back to the RPC. | Tab | Method + route | Feeds | |---|---|---| | `restrictions` | `GET /api/trade/v1/get-trade-restrictions` | WTO restrictions list with country filters and upstream-unavailable state. | | `tariffs` | `GET /api/trade/v1/get-tariff-trends` | Premium tariff-rate timeseries between reporting and partner countries. | | `flows` | `GET /api/trade/v1/get-trade-flows` | Bilateral merchandise trade-flow rows and year-over-year context. | | `barriers` | `GET /api/trade/v1/get-trade-barriers` | SPS/TBT barrier notifications filtered by country or measure type. | | `revenue` | `GET /api/trade/v1/get-customs-revenue` | US Treasury customs duties revenue; bootstrap-first via `customsRevenue`. | | `comtrade` | `GET /api/trade/v1/list-comtrade-flows` | Premium UN Comtrade strategic commodity flow search with anomaly flags. | The `revenue` tab's US-Treasury feed is particularly sensitive — see the changelog entry for "US Treasury customs revenue in Trade Policy panel" (`#1663`). ## Refresh cadence Per-tab fetches on mount and on tab switch; no polling. Upstream seeders run on varying cadences per dataset (tariffs daily, Comtrade monthly). ## Tier & gating **Panel shell is free.** No `premium` flag in variant registrations. The generated REST service is mixed: restrictions, flows, barriers, and customs revenue are public; `get-tariff-trends` and `list-comtrade-flows` are premium RPC paths and degrade to empty data without an entitled session or API key. ## API reference - [Trade service](/api/TradeService.openapi.yaml) — full schemas and query parameters for the six tab-backing RPCs.
