Shipping to Mexico: Where Parcels Stall in Customs

Which Service to Use for Mexico, and What It Costs#

What the Buyer in Mexico Pays on Delivery#

Every parcel to Mexico needs a customs declaration: PS Form 2976 (CN 22) for light, low-value items and PS Form 2976-A (CP 72) for Priority Mail International parcels. Declare a specific description, quantity, value, and country of origin per item, because Mexican customs runs a semaforo fiscal (a red-light/green-light system) that flags parcels for physical inspection, and a vague declaration raises your red-light odds. On charges: under about USD $50 clears free; USMCA makes courier parcels up to roughly USD $117 duty-free, though the 16% IVA can still apply above $50; from about $50 to $1,000 the parcel clears through simplified courier processing; above USD $1,000 it becomes a formal import needing a pedimento filed by a licensed Mexican customs broker (agente aduanal), and commercial recipients typically must supply their RFC tax ID. USMCA-qualifying goods can get reduced or zero duty when you state U.S. origin correctly, but the IVA is not waived by USMCA.

What Mexico Will Not Let In#

• Used clothing and second-hand textiles face strict import limits and often require special permits
• Firearms, ammunition, and many bladed or replica weapons are prohibited or need SEDENA permits
• Food, supplements, agricultural products, and plants need COFEPRIS or SENASICA clearance and are often held
• Prescription medicines usually require a Mexican prescription and can be seized without one
• Lithium batteries face packaging and quantity limits, tighter when shipped without the device
• Counterfeit or trademark-infringing goods are seized outright

Shipping to Mexico: Key Takeaways#

• Mexico's de minimis is low: under about USD $50 clears free, and USMCA raises the courier duty-free line to roughly $117.
• IVA is Mexico's 16% VAT, charged on value plus duty, and USMCA does not waive it.
• Parcels from about $50 to $1,000 clear through simplified courier processing; above $1,000 needs a pedimento and broker.
• Commercial imports often need the recipient's RFC tax ID, a top cause of held parcels.
• USPS hands off to Correos de Mexico for last mile; UPS Standard clears customs itself and often moves faster.

Structuring Mexico Orders Around the $50 and $1,000 Lines#

The single biggest lever on a Mexico shipment is declared value relative to two lines: the ~USD $50 de minimis and the roughly USD $1,000 formal-entry ceiling. Below $50, the parcel clears free, so low-value orders are effortless. Between $50 and $1,000 the buyer owes the 16% IVA and possibly duty, but clearance stays simple. Cross USD $1,000 and you trigger a formal import: a pedimento filed by a licensed Mexican customs broker plus, for commercial goods, the recipient's RFC tax ID. A single $1,100 order can sit for weeks that two $550 shipments would have avoided.

On carrier choice, the hidden variable is who handles clearance. USPS economy services hand off to Correos de Mexico, which adds last-mile time you do not control. UPS Standard and Worldwide Expedited file the customs entry themselves, so heavier or time-sensitive Mexico loads often clear faster on UPS even when the postage looks similar. Compare USPS and UPS on every Mexico label, or let Ship Intelligence pick the cheapest valid rate across both so you are not guessing per shipment.

• Keep low-value orders under about USD $50 to clear free of duty and IVA where you can.
• Split orders that would cross USD $1,000 to stay in the simplified band and skip the broker requirement.
• For commercial shipments, confirm the recipient can supply an RFC tax ID before you send.

Common Mistakes Shipping to Mexico#

Checklist for Shipping to Mexico#

• Confirm the item is not restricted, since food, medicine, and used textiles are frequently held or seized.
• Check declared value against the thresholds: under ~$50 clears free, $50-$1,000 is simplified, over $1,000 needs a broker.
• For commercial shipments, verify the recipient has an RFC tax ID before you ship.
• Complete the customs form with a specific description, quantity, value, and U.S. country of origin.
• State USMCA origin when goods qualify to reduce duty, but still quote the buyer the 16% IVA.
• Prefer UPS Standard for heavier or time-sensitive loads so UPS files clearance instead of a Correos handoff.
• Compare USPS and UPS on every Mexico label, or let Ship Intelligence pick the cheapest valid rate.
