Exporting from Mexico to the US: preparing the Mexican side

Name the Mexican company or person planning the shipment and describe the goods in ordinary language. Explain whether the movement is a sale, a return, equipment going abroad or another arrangement that needs review. Include the US destination and the party expecting to receive the goods. Keep the business purpose separate from the carrier's booking information. A buyer's purchase order may not explain whether the goods were manufactured in Mexico or previously imported. Make those facts visible in the initial review file. If your company has prior declarations or program records relevant to the goods, keep them available for the specialist's follow-up.

SAT's sectoral exporter-register guidance ties registration to listed product classifications.

Official reference: SAT: sectoral exporter registration ↗ · SAT: RGCE Anexo 10 listed sectors ↗

Ask the specialist whether your exact goods fall within a listed sector and what company information is needed for review. Do not infer that every exporter needs the same sector registration or that a previous supplier's status applies to your company. Provide the technical description and any existing classification as background. If purchasing or production uses only an internal code, ask for the corresponding product description. Keep the actual exporter file with the current goods information so the professional can discuss the operation your company intends to make, including questions that remain open before dispatch.

Gather the invoice information, buyer details, delivery terms and packing arrangement. Describe the contents of each group of packages so quantities and product models can be compared with the shipment brief. Explain whether the load will be split or collected from several locations. Keep revised invoices and packing documents clearly distinguished from earlier drafts. If the transaction is not an ordinary sale, describe the actual arrangement rather than forcing it into a sales description. Ask the specialist what supporting information is needed for that situation. A useful export file follows the real goods and transaction and shows where the original information came from.

SAT publishes pedimento (customs declaration) filling instructions, and SE publishes prior-permit rules for classified goods.

Official reference: SAT: current RGCE Anexo 22 pedimento instructions ↗ · Secretaría de Economía: prior-permit rules ↗

Ask the customs professional which declaration and product-control questions apply to the Mexican export being planned. Provide material, function, manufacturing origin and any relevant company program information. If a buyer asks for a document by a general name, ask what purpose it serves and who needs it. Keep Mexican-side questions separate from the US entry review so a completed task in one file is not assumed to finish the other. This guide gives no product approval or general exemption; the exact goods and operation need their own professional review.

USMCA chapter 4 sets origin criteria, and chapter 5 addresses the certification used for a preferential claim.

Official reference: USTR: USMCA chapter 4, origin rules ↗ · USTR: USMCA chapter 5, certification procedures ↗

Ask the buyer whether an origin document is being requested and what claim it is intended to support. Have the producer or responsible party supply the actual manufacturing facts for review. Do not treat shipment from Mexico as a complete origin conclusion. Keep the product models and the certifying party's role clear. If imported materials are used in production, explain the manufacturing process to the professional reviewing the relevant product rule. The quote request is not a certification and does not establish preferential treatment.

Write the pickup location, proposed customs office, transport mode and US destination into one route plan. Identify the carrier responsible for each leg and any transfer or warehouse stop. Ask who communicates readiness for pickup and who responds if the load differs from the packing information. Keep transport-document questions with the responsible issuing professional. If the route changes, send the new plan to the customs contact before relying on the earlier review. Explain delivery commitments to the parties without expecting an unsupported crossing-time promise. A clear handoff describes the actual movement and the person responsible at each stage.

Ask the buyer who is handling the US-side customs review and receiving instructions. Explain whether that work is already arranged or needs discussion. This site focuses on the Mexican operation and does not issue a US entry determination. Give the Mexican specialist the handoff contact and the requested destination information so the two sides can coordinate the same shipment facts. Keep US regulatory questions with the professional responsible for that filing. A completed Mexican export task does not by itself answer every question the US receiving party may have. Make the open responsibilities visible before the carrier is told to collect the goods.

Retain the completed declaration and the associated commercial and transport records supplied through the responsible contacts. Ask which document references connect the Mexican movement to the US handoff. In the business quote form, export is selected for this guide; you can change the direction if your operation involves both imports and exports. Describe the goods, exporter setup, US destination and any US-side need. Keep supporting documents ready for follow-up without uploading them or putting identity numbers into the public request. Include any existing shipment or program background that needs review, using a plain description rather than a guessed regulatory conclusion.
