How to Use International Mail-Order for Medications Safely and Legally in 2026

Buying medications from overseas used to be simple. For years, people in the U.S. could order prescription drugs from Canada, India, or the UK through the mail, pay a small fee, and have them delivered without paying any customs duty. That changed on August 29, 2025. The $800 de minimis threshold - the amount you could import duty-free - was eliminated for all commercial shipments. Now, if you’re ordering medication from abroad, you’re dealing with a completely new system. And if you don’t understand it, your package could be seized, fined, or never arrive.

What Changed in 2025?

Before August 2025, if you ordered a $60 bottle of blood pressure pills from a Canadian pharmacy, it came in without any extra fees. That’s because packages under $800 were considered "de minimis" - too small to tax. But on August 29, 2025, that rule vanished. Now, every commercial shipment entering the U.S. by mail, no matter how small, is subject to customs duties. The only exception? Private gifts under $100. That means if you’re buying meds from a foreign pharmacy, it’s no longer a gift. It’s a commercial import. And that triggers new rules.

Two Ways Duties Are Collected - And Which One Matters for You

There are two methods for collecting duties right now, and you need to know the difference:

• Method 1 (Ad Valorem): You pay a percentage of the item’s declared value. This rate varies by country and product type. For most prescription meds, it’s between 2% and 5%. So a $120 bottle of insulin might cost $3-$6 in duty.
• Method 2 (Flat Rate): A fixed fee based on the country’s tariff rate: $80 for low-tariff countries, $160 for medium, and $200 for high. This is where things get dangerous. If you order from a country with a 16%+ tariff rate - like some Asian suppliers - your $50 order could be hit with a $160 duty. That’s more than triple the cost of the meds.

Here’s the catch: Method 2 is only allowed until February 28, 2026. After that, only Method 1 is legal. So if you’re using a carrier that still offers Method 2, you’re playing with fire. Many international pharmacies still don’t understand this. They might quote you a "low price" but forget to tell you the duty could be $200. You’ll end up paying more than you would at a U.S. pharmacy.

HS Codes Are Now Mandatory - And They’re Tricky

Starting September 1, 2025, every international shipment must include a six-digit Harmonized System (HS) code. This isn’t just a formality. It determines the duty rate. For medications, the most common codes are:

• 3004.90 - Other medicaments (most prescription pills)
• 3004.20 - Insulin and other hormones
• 3004.30 - Antibiotics

If the pharmacy uses the wrong code - say, they label your insulin as "dietary supplement" - CBP can reclassify it and apply a 300% higher duty. One user reported their $80 insulin order was reclassified as a "cosmetic product" and hit with a $200 duty. That’s not a mistake. That’s a penalty.

Always ask your overseas pharmacy for the exact HS code on the commercial invoice. If they don’t know it, find another supplier.

Documents You Can’t Skip

You’re not just filling out a form. You’re creating a legal record. Missing documents = seized package. Here’s what you need:

• Commercial Invoice: Must list the medication by its generic name, dosage, quantity, and manufacturer. No "vitamins," "supplements," or "health products." If it says "for personal use," it’s still commercial if you’re paying for it.
• Packing List: Matches the invoice. If the invoice says 30 pills and the box has 50, CBP will flag it.
• Prescription or Doctor’s Note: Not required by law, but highly recommended. If you’re importing controlled substances (like Adderall, Xanax, or opioids), you’ll be asked for proof it’s for personal use. Without it, your package is gone.

Don’t rely on the pharmacy to handle this. Many overseas sellers don’t know U.S. rules. Print your own invoice and send it to them to include. Use a template from the U.S. Customs and Border Protection website.

Who Pays the Duty? And Why It’s Your Problem

This is the biggest confusion. The carrier (USPS, DHL, etc.) doesn’t pay. The pharmacy doesn’t pay. You do. CBP will send you a notice - usually by mail or email - demanding payment before delivery. If you ignore it, your package gets destroyed or returned. Some carriers will pay the duty upfront and bill you later, but they add a 15-25% handling fee. That’s why some people end up paying $250 for a $75 medication.

There’s no way around this. Even if you use a "trusted" pharmacy, you’re still the importer of record under U.S. law. That means you’re legally responsible. No exceptions.

What Carriers Still Work?

Deutsche Post, Canada Post, and many other national postal services stopped accepting business parcels to the U.S. after August 22, 2025. That means you can’t just drop off a package at your local post office and expect it to go through.

Only three carriers are reliably handling commercial medication shipments now:

• DHL Express - Handles customs clearance automatically. Best for high-value or time-sensitive orders.
• FedEx International - Offers duty-paid options. You pay upfront, no surprises.
• UPS Worldwide Express - Similar to FedEx. Good for tracking and documentation.

USPS still delivers, but only if the shipment is pre-cleared by a bonded carrier. If you order from a small pharmacy that uses USPS, your package will sit in customs for weeks - if it gets through at all.

What Medications Are Still Allowed?

Not all meds are legal to import, even if you pay the duty. CBP allows personal use imports of non-controlled substances under these conditions:

• Up to a 90-day supply
• For a condition diagnosed by a U.S. licensed physician
• Not a controlled substance (Schedule II-V drugs like opioids, stimulants, benzodiazepines)
• Not for resale

Controlled substances? Almost never allowed. Even if you have a foreign prescription, U.S. law doesn’t recognize it. You can’t legally import Adderall, Xanax, or Vicodin from overseas - no matter how much duty you pay.

Real Cost Comparison: U.S. vs. Overseas

Let’s say you need a 30-day supply of generic Lisinopril (blood pressure). Here’s what it costs now:

Cost Comparison for 30-Day Lisinopril Supply

Source	Price	Duty (Method 1)	Shipping	Total
U.S. Pharmacy (with coupon)	$4	$0	$0	$4
Canadian Pharmacy (mail-order)	$12	$0.60	$8	$20.60
Indian Pharmacy (mail-order)	$5	$0.25	$12	$17.25

Even with low duties, shipping and handling make overseas orders barely cheaper - and far riskier. If your package gets held up for 6 weeks, you’re out of meds. In the U.S., you can get it in 24 hours.

When It’s Still Worth It

There are two cases where international mail-order still makes sense:

1. You need a medication that’s not available in the U.S. - like certain compounded hormones or rare generics from the EU.
2. You’re buying a long-term supply (90+ days) of a non-controlled drug, and the savings are 50%+ after duty and shipping.

For most people, it’s not worth the hassle. The time, risk, and paperwork outweigh the savings.

Red Flags to Avoid

If a pharmacy does any of these, walk away:

• Says "no prescription needed"
• Uses vague terms like "health supplement" or "dietary aid"
• Won’t provide an invoice with HS code
• Offers "free shipping" - that usually means they’re hiding the cost in the product price or won’t pay duties
• Asks you to lie on the customs form

These aren’t mistakes. They’re illegal. And you’re the one who gets punished.

What Happens If You Get Caught?

CBP doesn’t fine every person who imports a $20 pill. But they do:

• Seize packages that violate the law
• Require payment of duties plus penalties (up to 3x the value)
• Flag your name for future inspections
• In rare cases, refer to the DEA if controlled substances are involved

You won’t go to jail for a single $50 order. But if you do it repeatedly, you become a target. And your next package? It won’t even make it to the border.

Bottom Line: Is It Still Worth It?

The short answer? For most people, no.

The $800 de minimis rule made international medication shopping easy. Now, it’s a minefield. The savings are smaller. The risks are bigger. The paperwork is heavier. And the penalties are real.

If you’re considering it, ask yourself:

• Is this medication available in the U.S.?
• Can I get a discount through my pharmacy or insurance?
• Am I willing to pay $100+ in fees for a $30 drug?
• Can I afford to wait 6 weeks if it gets stuck in customs?

If you answered "no" to any of those, don’t risk it. Use your U.S. pharmacy. Ask about patient assistance programs. Talk to your doctor about generics. There are legal, safe, and cheaper ways to manage your meds - without crossing international borders.
