IMMEX versus definitive import: which regime needs review?

Write down what the goods will do after they enter Mexico. Explain whether they will be installed, sold, consumed in production, incorporated into an exported product or returned after a service. Name the company receiving them and the site where they will be used. Keep the description practical enough for purchasing, production and customs contacts to understand in the same way. A statement such as factory use does not explain the full plan. Describe the incoming goods, the work performed and the intended destination of the resulting goods. If the plan is still under discussion, say which decisions have not yet been made.

ANAM's glossary distinguishes customs regimes, including definitive import and temporary import. SE describes IMMEX as a program connected to export manufacturing and services.

Ask the specialist which arrangement needs review for the actual movement you have described. Do not assume that all equipment used by a manufacturer belongs under IMMEX, or that every temporary movement uses the same procedure. Keep the business purpose connected to the intended importer and the relevant company file. If a supplier proposes a particular regime, ask what facts and authorization it has considered. Treat that proposal as a question for the customs professional rather than a completed eligibility decision.

If the company uses IMMEX, have its responsible contact provide the actual authorization and explain the activities covered for professional review. Identify the establishment using the goods and any existing production arrangement relevant to the shipment. Keep a distinction between the company's program description and the scope of the goods you are buying now. If the operation has changed suppliers, sites or product models, make those changes visible. A commercial statement that a company exports does not explain its authorized program. Ask the customs broker what information is needed to compare the proposed movement with the current company file before choosing the filing plan.

For a manufacturing discussion, show how the incoming materials or components will be used and what happens to the resulting goods. Explain which team knows the production process and which team maintains the working inventory records. Keep descriptions consistent between supplier information and internal production language. If the same material is used in several product lines, identify those uses rather than assuming the specialist knows your internal codes. Ask which facts need confirmation for the proposed customs arrangement. This preparation does not establish compliance; it makes the operational plan understandable enough for the professional review to address the real goods and flow.

SAT's RGCE 2026 index identifies Anexo 24 for automated inventory controls and Anexo 30 for the credit and guarantee account system.

Ask the company's program contact and the customs specialist which controls apply to the operation under review. Have them explain how the incoming shipment will be connected to the records already maintained by the company. Do not treat an annex number as proof that a particular company satisfies the requirements. Keep evidence of the current setup and raise any unresolved process questions before the shipment is booked. If a previous procedure used different references, review the current official index rather than repeating an older annex label.

Prepare the product specifications, manufacturing origin and supplier documents for the specialist. Explain changes in material, condition or intended use even if the company has imported similar goods before. Ask which registration, permit or standards questions remain to be reviewed against the current classifications and operation. A regime discussion should not obscure a missing product fact. Keep a list of open questions and identify who can obtain each answer. If purchasing wants to replace one model with another, circulate the updated technical sheet before relying on the earlier review. The goods themselves and the company's setup need to be understood together.

Agree which company contact supplies program records, which person confirms production information and which person coordinates the carrier. Ask how the customs professional will communicate a missing document or a changed shipment instruction. Keep a shared version of the planned route and goods list. If there is an existing customs broker, explain the handover and which operations are already in progress. Avoid asking a new professional to infer the status from a previous declaration alone. Organize the background records for review and retain the original company explanations so the new shipment can be discussed with a clear understanding of what has already happened.

Use the business quote form to explain the goods, importer and intended use. Describe whether an IMMEX authorization is already in place or whether you are comparing possible arrangements. Do not select a program regime merely because you prefer its commercial consequences. Keep the original operational facts in the request and leave uncertain technical conclusions for the specialist. This guide provides no costs or rates and gives no eligibility finding. Ask the customs broker to explain the proposed regime, supporting information and work needed for the actual shipment. Keep the company program documents ready for follow-up rather than uploading them through the form.
