Two carrier networks. Two countries. One broker in the middle. Goldmex provides the API bridge that connects Gori/ShipBae (US last-mile delivery) and Estafeta (Mexican domestic logistics) through a single licensed customs broker. We bring carriers pre-cleared, compliant volume — and we bring shippers a single integration that works on both sides of the border.
Imagine two excellent carrier networks — one in Mexico, one in the United States — that have no idea how to work together. Estafeta can pick up a package in Guadalajara and deliver it to the border in hours. Gori can take that same package from a US warehouse to any doorstep in America. But between those two networks sits a wall: US Customs and Border Protection.
Goldmex is the keystone in that arch. We sit between the two carriers and handle everything that happens at the border: HTS classification, duty calculation, PGA screening, CBP entry filing, and cargo release. When a package arrives at our customs layer, it exits the other side pre-cleared and ready for the next carrier leg. No customs holds. No PGA rejections. No gaps in compliance.
For carriers, the pitch is simple: we bring you clean, compliant, pre-cleared volume. You deliver packages. We handle the border.
Gori aggregates USPS, FedEx, UPS, and DHL rates through a single API. We query all available services in real time and return options with duties and compliance fees included. For high-volume shippers, Gori offers negotiated contract rates that beat published tariffs. Our integration supports all Gori service levels from economy ground to next-day air.
Estafeta is Mexico’s leading private parcel carrier with nationwide coverage and same-day pickup in major metro areas. We integrate their domestic and cross-border services so you can book a pickup in Mexico City, have the package customs-cleared at the border, and handed off to a US carrier — all through a single API call. Estafeta tracking events feed directly into our unified tracking system.
Provide your Gori/ShipBae API credentials for US last-mile and your Estafeta account for Mexican domestic legs. Our integration layer normalizes both APIs into a single rate-and-ship interface. Setup takes one call — we handle the plumbing.
Every package routed through Goldmex is classified to a 10-digit HTS code and screened against all 16 PGA agencies before it reaches a carrier. By the time your driver picks up the shipment, the customs entry is already filed and the cargo is cleared for release.
Query Gori rates (USPS, FedEx, UPS, DHL) and Estafeta rates in a single API call. We return all options sorted by price, speed, or value — with duties and compliance fees already included. No surprise surcharges after the label is printed.
Select a rate, generate the label, and the customs filing happens automatically in the background. Your end customer sees one tracking number that works from pickup in Mexico to doorstep in the US, or vice versa.
Gori handles US last-mile. Estafeta handles Mexican domestic. But neither of them does customs. Goldmex is the keystone — the licensed broker that connects two carrier networks that otherwise could not talk to each other across the border.
For carriers: every package we route to you has already been classified, screened, and cleared through CBP. No customs holds, no PGA rejections, no returned-to-sender packages. Clean volume, every time.
A single REST endpoint handles rate shopping, label generation, and customs filing for both northbound and southbound shipments. You do not need to integrate Gori and Estafeta separately — our abstraction layer does it for you.
Ship from Mexico to the US or from the US to Mexico using the same integration. Northbound shipments get CBP entry filing; southbound shipments get Mexican VUCEM/pedimento support. Same API, same dashboard, both directions.
Rate queries return in under one second with cached classification data. Repeat SKUs are classified once and cached permanently, so rate shopping is limited only by carrier API latency — not ours.
Multi-tenant support lets you manage multiple shipper accounts under one integration. Each account gets its own classification history, filing records, and billing. Perfect for 3PLs that fulfill for dozens of brands.
Whether you are a carrier looking for compliant cross-border volume or a shipper looking to rate shop across both sides of the border, we have an integration path for you.
