Shipping to Mexico: Where Parcels Stall in Customs
Mexico is a cheap lane on paper with the strictest clearance rules of any USMCA partner: a low tax-free threshold, IVA on top, and a broker requirement above roughly USD $1,000.
- Customs form
- PS Form 2976 + 2976-A
- Recommended
- USPS First-Class Package International Service
- Typical cost
- $19.21-$42.42 USPS commercial
- Typical transit
- Varies by destination
Shipping to Mexico costs $19.21 to $42.42 on USPS First-Class Package International Service at USPS commercial prices (up to 8 oz through 4 lb), with delivery time that varies by destination, or ships on UPS® Standard in 4-8 business days at a rate quoted live.
Postage is cheap because the border is short; the clearance rules are what stall parcels. Three numbers drive everything. Import taxes apply to goods with a declared value over USD $50, as the USPS country listing for Mexico states.
Parcels valued from about USD $50 to $1,000 clear through a simplified courier process. Anything above USD $1,000 needs a formal entry, a pedimento filed by a licensed Mexican customs broker, and commercial imports often need the recipient's RFC tax ID.

What the Buyer in Mexico Pays on Delivery#
Where the declared value crosses a line
Mexico, low-value parcelsUSD
Import taxes apply to goods with a declared value over USD 50, per the USPS country listing for Mexico.
Mexico, simplified or formal entryUSD
Up to USD 1,000 the parcel clears through simplified courier processing; above it, it needs a pedimento filed by a licensed Mexican customs broker.
Each row is on its own scale in local currency; the rows are not comparable without an exchange rate. Figures as stated in this guide’s customs section. Thresholds and rates change; confirm with the destination’s customs authority before quoting a buyer.
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: import taxes apply above USD $50 of declared value; 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
- Pharmaceutical products, electronic cigarettes, and jewelry are prohibited in mail to Mexico
- USPS international mail accepts lithium batteries only when they are new and installed in the device they power, up to four cells or two batteries per parcel; loose or spare batteries, and used, damaged or defective devices with lithium batteries, cannot be mailed internationally
- Counterfeit or trademark-infringing goods are seized outright
Shipping to Mexico: Key Takeaways#
- Mexico's tax-free line is low: import taxes apply above USD $50 of declared value.
- IVA is Mexico's value-added tax, 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 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 if the buyer was not ready for the import formalities.
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.
- Tell the buyer before you ship an order above USD $1,000 and confirm they can complete the import formalities; do not split one order into several parcels to get under a customs limit.
- For commercial shipments, confirm the recipient can supply an RFC tax ID before you send.
Common Mistakes Shipping to Mexico#
| Mistake | Why It Hurts | Better Approach |
|---|---|---|
| Assuming USMCA means no charges to Mexico | USMCA can zero the duty but never the IVA, so a $200 order still hits the buyer with a tax bill they did not expect. | Tell buyers IVA applies above the USD $50 line regardless of USMCA, and factor it into landed-cost quotes. |
| Letting a single order cross the USD $1,000 formal-entry line | The parcel needs a pedimento and a licensed customs broker, and often the recipient's RFC, adding fees and weeks. | Tell the buyer about the import formalities above USD $1,000 before you ship and confirm they can complete them; do not split one order into several parcels to get under a customs limit. |
| Writing a vague description like gift or merchandise on the customs form | It raises your odds of a red-light physical inspection under the semaforo fiscal, holding the parcel for days. | Declare a specific description, HS-consistent detail, quantity, value, and U.S. origin for every item. |
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 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.
Shipping to Mexico: Questions Senders Ask#
Shipping to Mexico costs $19.21 to $42.42 on USPS First-Class Package International Service at USPS commercial prices, and from $59.47 at 1 lb on Priority Mail International, which USPS lists at 6-10 business days. UPS® Standard takes 4-8 business days, with its rate quoted live. Clearance charges are separate from the postage.
Mexico applies stricter clearance rules than other USMCA partners. Parcels above roughly USD $1,000 need a formal pedimento entry filed by a licensed Mexican customs broker, and commercial imports often need the recipient's RFC tax ID. Missing either one holds the parcel until the recipient supplies it.
The $40 order sits under Mexico's ~USD $50 de minimis, so it clears free of duty and tax. The $200 order is over the line: it lands in the simplified $50 to $1,000 band, so your buyer pays IVA plus any duty and a courier processing fee. If the goods qualify under USMCA with correct U.S. origin, the duty can drop to zero, but the IVA still applies. That surprise is why warning the buyer before you ship matters.
Partly. USMCA can reduce or zero the duty on qualifying U.S.-origin goods when you state origin correctly on the customs form. But USMCA does not touch Mexico's IVA, which still applies on value above the USD $50 line. So a qualifying good can owe zero duty and still owe IVA.
A USD $200 order to Mexico falls in the simplified courier band between about USD $50 and $1,000, so it clears without a formal entry but IVA can apply to the declared value plus any duty. Below about USD $50 the shipment clears free of duty and tax entirely.
Only up to a point. Import taxes apply above USD $50 of declared value, whatever the origin claim does to duty. Above USD $1,000 the shipment needs a formal pedimento entry filed by a licensed Mexican customs broker regardless of origin.
The RFC is Mexico's taxpayer registration number. Commercial imports into Mexico often require the recipient's RFC before customs will release the parcel. Confirm it before shipping business-to-business, because a missing RFC holds the shipment until the recipient supplies it rather than triggering a return.
