How it's published

Feed (what to expect)

UN Comtrade preview API (~500 rows/call); we vendor a slice - BACI is the reconciled bulk.

Cadence: annual (monthly available)
Access: free preview tier only (~500 rows/call, throttled) - insufficient for the bilateral panel; usable bulk needs a paid Comtrade Plus subscription / data-endpoint key
Format: JSON
Licence: UN Comtrade - free use with attribution
Vintage: 2026-06-17
Upstream: https://comtradeapi.un.org/public/v1/preview/C/A/HS

Quirks

Primary national-customs reports (NOT mirror-reconciled like BACI); ranked below BACI on overlap
Operator-pulled via `strata comtrade pull` -> data/raw/comtrade_hs22/<vintage>/flows.jsonl
Country codes are M49 numeric; resolved to ISO3 via the Reporters reference at pull time
Free preview endpoint caps at ~500 rows/call and is throttled; a key unlocks the faster data endpoint

Fills BACI's ~14-month publication lag + recent years; same BilateralTradeFlow cell
