CURRENT MONTHLY TRADE

U.S. Census current trade

Published catalog available

Latest published periodAugust 2026 · catalog published Oct 26, 2026, 8:15 AM UTC

Monthly releaseCensus monthly international-trade series are updated with the monthly release. The catalog publication timestamp is shown separately from its latest statistical month.

Public trade profilesPort imports and exports use reported vessel values. Partner and HS2 product pages compare the latest statistical month with the same month a year earlier. Their two observations are not a continuous monthly history. Monthly filtered histories remain available in the interactive explorer.

Detail refresh and retentionPartner and product aggregates are refreshed in a daily bounded rotation for Los Angeles, Long Beach, Oakland, Savannah and Norfolk. Each direction retains its last complete observation on a provider failure; total-value reconciliation and source-age checks govern publication. Customs-port identities are matched explicitly and are not inferred from similar maritime-port names.

Measure and classificationImports use General Imports value (GEN_VAL_MO); exports use total value (ALL_VAL_MO). HS2 is the default product grouping. An optional selected HS2, HS4, or HS6 code can narrow a detail query; the port-total catalog does not enumerate every commodity code.

Countries and missing valuesPartner filters use individual four-digit Census country codes. Census country-group aggregate rows are excluded to avoid double-counting. Null measurements mean unavailable; they are not converted to zero.

Geographic scopePort selections are Census Schedule D statistical ports. A Census port code is not an exact physical-facility boundary, an individual shipment, or a bill of lading.

Separate archived historyRetained January 2022–December 2025 IMDB monthly import summaries remain a distinct historical source. The current API catalog does not replace or revise those archive observations.

CAPABILITY BOUNDARY

Read each feed at its supported scale

Current, retained, and reference data stay distinct

Current maritime activityGlobal AIS is sampled current vessel state only. PortWatch current activity is published against the provider’s full current registry.

Historical AISHistorical AIS is separate from the current sampler and appears only through explicitly authorized bulk imports with their own source evidence.

Road statusFreightWeave has no road-status feed. Reference road geometry is not traffic, routing, or operational status.

Retained rule comparisons	Rule comparisons report changes between two retained-knowledge cutoffs, including source revisions, declared dates and documented relationships.

USGS earthquakes	Rolling seven-day earthquake locations. They do not establish port impacts; a tsunami flag is not a tsunami warning.	USGS Earthquakes ↗
NWS alert geometry	The knowledge cutoff selects a retained packet; the event cursor filters its declared effective-to-expiry windows, including the start and excluding expiry. Gray areas have unknown or invalid timing, rather than confirmed activity. Retained geometry may also be missing. Missing coverage is unknown, not an all-clear, and no gateway impact is inferred. Historical gateway views use static reference geometry, not a dated gateway registry. Current metrics, news, routes and source health are not substituted where their historical records are unavailable.	NOAA / NWS API ↗
Gateway exposure	Matches use retained NWS alert polygons within 50 km and earthquake epicenters within 250 km of a gateway reference point. The retrieval cutoff controls what was known; an optional event time filters event windows. Missing snapshots or geometry remain unknown. Proximity does not establish disruption, damage, or operational impact.	NOAA / NWS ↗ · USGS ↗

SCHEDULE

Update schedule

FMC register, FMC-1 tariff report, and non-compliant listDaily at 08:15 UTC from the core daily branch.

PortWatch daily activity and coverageDaily refresh at 08:15 UTC, with hourly retry and coverage dispatch at :45 UTC. Failed or partial work retains last-good observations.

NWS national retained historyHourly at :45 UTC. Failed or partial work retains last-good observations.

USGS M4.5+ earthquake feedEvery 15 minutes. Rolling weekly coverage; proximity does not establish port impact.

USGS water observationsAutomatic refresh is disabled. Retained observations remain available; enabling collection requires a server-side API key.

Census tradeThe current catalog is checked daily at 08:15 UTC when current collection is enabled; Census publishes the underlying series monthly. Historical archive summaries remain imported in verified batches.

Gateway NWS alerts and Federal RegisterAutomatic collection is disabled. National NWS alerts use the separate hourly schedule above.

PortWatch port registryDaily retained registry refresh with hourly retry; published versions remain available for current-data joins.

PortWatch reference network and chokepointsVerified static local artifacts; not live routes or daily chokepoint observations.

NOAA historical AISCheckpointed local operator only; no cron. Current implementation baseline is one bounded LA–Long Beach day/area partition.

CBP border waits and AISStreamCBP remains a retained sample. AISStream samples three global longitude shards every 15 minutes, keeps current state only, and excludes positions without a current source-reported cargo type.

USAspending and GLEIF lookupsRun hourly at :45 UTC from the current Worker branch. Matches use the company’s legal name and address.

Schedules describe collection attempts, not guaranteed freshness. See the source catalogue for the latest stored status.
