Agent-curated monthly TEU panel for 9 North American container gateways (7 US: Los Angeles, Oakland, Oakland, Seattle/Tacoma, New York & New Jersey, Charleston, Savannah, Houston; 2 Canadian: Vancouver, Montreal), one row per port x month. Columns: loaded-import / loaded-export / empty TEU splits where the port publishes them (honest nulls otherwise), split shares, 12-month YoY and 3-month momentum on total TEU, and a documented 0-100 gateway_momentum_index = round(100*(0.6*clip01(teu_yoy_pct/30) + 0.4*clip01((teu_mom3_pct+25)/50))) with neutral 0.5 fill for a missing term (null when both are missing). Per-row source_url + verification_level (official_stats_page / official_press_release / secondary_citing_authority) + preliminary_flag record the provenance. Join on (year_month, port_code / coast / state_code) to time purchase orders, promo calendars, and freight-cost forecasts against import momentum. Caveats: ports revise the latest 1-2 months; split detail varies by port; Halifax is quarterly.

Column	Type	Description
port_code	string	Canonical port slug (los-angeles, oakland, seattle-tacoma, new-york-new-jersey, charleston, savannah, houston, vancouver, montreal). Primary join key with year_month.
port_name	string	Port authority name as published.
city	string	Port city / metro.
state_code	string	US state or Canadian province code (e.g. CA, NY, BC, QC). Join key to shop/territory geography.
country_code	string	ISO alpha-3 country: USA or CAN.
coast	string	Coast bucket: west, east, gulf, canada-pacific, canada-atlantic. Join key for coast-level analysis.
year_month	string	Calendar month the TEU figures describe (YYYY-MM). Primary join key.
teu_loaded_import	float	Loaded import TEU (inbound full containers). Null where the port publishes total TEU only. (unit: TEU)
teu_loaded_export	float	Loaded export TEU (outbound full containers). Null where unpublished. (unit: TEU)
teu_empty	float	Empty-container TEU repositioned. Null where unpublished. (unit: TEU)
teu_total	float	Total container throughput for the month. Float: POLA publishes fractional TEU (to the cent). (unit: TEU)
import_share	float	Loaded imports / total (0..1). Null when the split is unpublished.
export_share	float	Loaded exports / total (0..1). Null when the split is unpublished.
empty_share	float	Empties / total (0..1). Null when the split is unpublished.
teu_yoy_pct	float	100*(x_t - x_{t-12})/x_{t-12} on total TEU (percent). Null until a 12-months-ago observation exists. (unit: percent)
teu_mom3_pct	float	100*(sum(last 3) - sum(prior 3))/sum(prior 3) on total TEU (percent). Null until 6 months of history exist. (unit: percent)
gateway_momentum_index	float	0-100 import-momentum composite = round(100(0.6clip01(teu_yoy_pct/30) + 0.4*clip01((teu_mom3_pct+25)/50))). A missing term contributes 0.5 (neutral); null when both terms are missing.
preliminary_flag	integer	1 when the port labels the month's figures preliminary / subject to revision.
verification_level	string	official_stats_page: read from the port authority's published statistics page. official_press_release: read from the port's official press release. secondary_citing_authority: port-authority figures reproduced by a secondary publisher, corroborated against the authority's own documents.
source_url	string	Exact page the month's figures were read from on 2026-09-30.
collected_at	string	Date the statistics were read (ISO date).
notes	string	Per-row collection notes (unit conversions, fiscal calendar adjustments, gaps).
row_hash	string	Deterministic row key: first 16 hex chars of sha256 over port_code\|year_month\|teu_total.

First 10 sample rows — a preview, not the complete dataset.
