Agent-curated cost intelligence: 75 surcharge-window rows covering UPS, FedEx, Amazon Shipping, OnTrac, and USPS for the 2026-27 peak season (2026-09-26..2027-01-17). Each row gives the carrier, charge line (per-package demand, accessorial demand, or USPS rate increase), the exact pricing window (shoulder / peak / close), the USD amount, and a per-row verification level (UPS read verbatim from the carrier's official schedule; FedEx and USPS cross-verified across independent sources; Amazon Shipping from four agreeing analyses; OnTrac from a single compiled table). Join to shop orders by ship date + carrier for Q4 margin and shipping-cost forecasting. Provenance: agent-curated (intel-3 run 2026-09-30) from the carriers' published schedules; the code encodes the schedules verbatim and derives ids and hashes. Caveats: high-volume (>20k/week) tiered tables excluded (enterprise only); USPS stacks on the April 2026 temporary 8% change; retail USPS amounts excluded (commercial table encoded).

carrier	string	Carrier: UPS, FedEx, Amazon Shipping, OnTrac, USPS. Join key.
charge_name	string	Charge line name as published by the carrier.

window_start	date	First date the amount applies (ISO date, inclusive).
window_end	date	Last date the amount applies (ISO date, inclusive).
amount_usd	float	USD amount. For rate_increase rows this is the per-package add-on for the given weight band + zone. (unit: USD)
amount_unit	string	usd_per_package (demand surcharge added on top of base rates) or usd_per_package_increase (USPS rate-table add-on).

source_domain	string	Domain the row's figures were read / cross-verified from on 2026-09-30.
