Mexico's 2026 tariff changes: goods and origins to review

The December 29, 2025 decree took effect January 1, 2026. It lists classifications including specified plastics, footwear, automotive parts and furniture; it is not a change to every product.

Find the technical description of your own goods before comparing them with the publication. Broad commercial categories are only a starting point. A description such as furniture can cover several materials and constructions; an automotive part can have a specific function that matters to classification. Keep the exact model and manufacturing information in your file. Ask the customs broker to review the relevant product line in the original decree. This guide provides no percentage or calculation.

The April 23, 2026 decree took effect April 24, 2026. It changes listed classifications, including chemicals and musical instruments, and specified PROSEC (sectoral promotion program) entries.

Review whether a later publication addresses the exact goods you intend to import. Keep the proposed filing date with the product information rather than assuming the beginning-of-year position covers the entire year. If your company holds a production-program authorization, tell the specialist what authorization and product scope it has. Do not infer program treatment from your industry name alone. The actual rates and product descriptions remain in the official publication linked here, where the customs professional can check them against your shipment.

The April decree preserves treaty treatment for qualifying origins. Goods without an applicable treaty preference need review under the general tariff or a relevant program. USMCA origin depends on production and product-specific rules.

Ask whether your goods have a supported treaty-origin claim or need review under the general tariff and any relevant program. Goods made in China and merely stored in the United States do not acquire a US production history from that storage. Keep manufacturing country, seller country and pickup country separate. For a product produced in North America using imported materials, ask for a product-specific origin review rather than assuming the presence of those materials resolves the question. The effect on an origin is assessed with the classification, applicable agreement and evidence, not a shipping address.

Collect the manufacturer's product sheet, material composition, function and clear model description. If the supplier has already assigned a code, include it as information to review and say which country used it. Describe whether the goods arrive assembled, in parts or as components of a larger system. Keep different products separated even when sold together in one purchase. Ask the specialist which facts are missing before the classification can be reviewed. Do not choose a description because it appears more favorable in a tariff table. The product file should describe the goods as they actually are, including technical distinctions that a sales invoice may omit.

Record when the shipment is expected to be ready, where it is now and whether transport has already been booked. Ask the customs broker which effective publication applies to the actual filing circumstances. Keep a purchase date separate from a proposed border arrival or declaration date; they answer different planning questions. If the schedule changes, circulate the change with the same product and origin information used for the initial review. A dated guide is a research aid, not a guarantee that no later publication exists. Use the rules-update page to find the cited documents and ask about the position for your own operation.

Ask the party making an origin claim to explain the supporting records and the products covered. If the business uses a program, have the responsible company contact provide its actual authorization and operation details for professional review. Keep that information separate from a general statement that the company is a manufacturer. A specialist needs to know what the goods are and how the proposed arrangement fits the current file. Do not borrow an origin document from a different product or presume another company's program applies to your purchase. Record unanswered questions so the company, producer and customs professional can address them before the filing plan is settled.

Use the DOF links for the actual tariff text and rates. This site deliberately explains the goods, origins and effective dates without reproducing numerical charges. Ask the customs broker to explain the treatment relevant to the reviewed classification in the quote. If an online summary disagrees with the original publication, keep the official source in the discussion. Avoid turning a list of sectors into a prediction for every product sold in that sector. Check the exact product description and any later change with the specialist. The useful output of your preparation is a clear review file, not a self-calculated clearance amount.

Describe the products, manufacturing country, proposed route and importer setup in the quote form. Include a known classification if you have one, and explain whether its basis still needs review. Tell us if you are asking about treaty-origin evidence or a production-program arrangement. Choose the business or personal variant that fits the intended shipment; the form remains editable. Keep purchase documents ready for the specialist rather than uploading them or adding confidential identifiers to the request. If the goods are already moving, describe their current location and the question needing attention. A customs specialist will contact you about the request and the actual shipment review.
