How to Buy From Korea Without Surprise Customs Fees (2026 US Guide)

Every order from Korea now owes US duty no matter how small. Here is how the charges work in 2026 and what to confirm with a seller before you pay.

Since August 29, 2025, there is no duty-free threshold for goods shipped to the United States, so every purchase from Korea is dutiable, even a $20 one. The surprise bill happens when a seller ships with duties unpaid and the carrier charges you the duty plus its own handling fee before it will hand over the box. You avoid it by confirming, before you pay, that the seller ships with duties prepaid and that the checkout total is the final amount.

The rest of this guide explains how the charges are built, where the extra fees come from, and the exact questions to send a seller.

What changed, in one paragraph

For years, a shipment worth $800 or less could enter the US free of duty under what was called the de minimis exemption. Executive Order 14324 suspended that treatment for all countries starting August 29, 2025, and US Customs and Border Protection (CBP) made the suspension indefinite by regulation in June 2026. CBP's own FAQ now says that shipments valued at $800 or less must go through formal or informal entry and that all applicable duties, taxes and fees must be paid. The full timeline is in our guide to the end of the $800 rule.

Who actually owes the money

Legally, you do. CBP's guidance for online shoppers is blunt: when you buy goods from foreign sources, you become the importer, and CBP holds the importer liable for the duty, not the seller.

That does not mean you must be the one who pays in practice. A seller can pay the duty on your behalf before or during shipping. What matters is whether the seller has arranged that, and whether they have told you clearly.

How the duty is calculated

Three facts about the item decide the bill:

What it is. Every product has a classification in the Harmonized Tariff Schedule (HTS), and each classification has a base rate.
Where it was made. Duty follows the country of origin, which is where the product was manufactured, not where it was shipped from. A Japanese-made item mailed from Seoul is still a product of Japan.
What it is worth. Most duties are a percentage of the declared value.

A worked example: trading cards

Base rates can be zero. In ruling N359352 (March 16, 2026), CBP classified Pokémon trading cards from Japan as playing cards under HTS 9504.40.0000 and stated that the general rate of duty is Free.

The same ruling warns that it does not address additional duties under Chapter 99 of the tariff schedule, and those are what you pay today. Since July 24, 2026, a Section 301 action by the US Trade Representative applies to imports from 60 economies. According to trade law firm summaries of that action, products of South Korea and Japan are assessed the higher of 12.5% or the product's normal duty rate. For an item whose normal rate is Free, that works out to 12.5% of the value, unless a specific exclusion applies.

Two cautions. First, tariff measures have changed several times since 2025 and this one is being challenged in court, so check the current position before a large purchase. Second, only CBP makes the final determination on any shipment. A seller's estimate is an estimate.

The three charges on a duty-unpaid parcel

When a seller ships without prepaying, the amount you are asked for at delivery usually has more than one part.

The duty itself. This goes to the US government.
The carrier's fee for fronting it. Express couriers typically pay the duty to CBP so the parcel can keep moving, then bill you. DHL's FAQ describes exactly this: it pays on the receiver's behalf and collects payment prior to or on delivery, and it lists an advance payment charge among the possible extras. Other couriers have similar fees under names like disbursement or brokerage fee. These are set by each carrier and change often, so look up the current schedule rather than trusting a number in a blog post.
Government processing fees. CBP's FAQ notes that the Merchandise Processing Fee does not apply to mail shipments, with the exception of inbound EMS items.

CBP's shopper guidance makes the same point from the other side: what people call customs fees are often charges for the broker's services, and the total of duty, broker fees and shipping can exceed what you expected to pay for the goods.

On a low-value order, the carrier's flat minimum fee can be larger than the duty. That is why a small unpaid parcel can produce a bill that feels out of proportion.

Mail versus express courier

Express couriers (FedEx, UPS, DHL). The courier acts as the customs broker. If the shipper's account is set to bill duties to the sender, you pay nothing at the door. If it is set to bill the receiver, you get a text or email with a payment link, or a request for payment on delivery.

Postal mail (Korea Post EMS, air parcel, K-Packet). The 2025 executive order required duties on postal items to be collected and remitted to CBP by the transportation carrier or another qualified party. Korea Post stopped accepting US-bound parcels in late August 2025 and resumed on September 22, 2025 with a prepaid model: working with a CBP-approved customs broker, it charges the sender the applicable tariff at the counter so the item clears as delivered duty paid. Korea JoongAng Daily reported that this applies to EMS, international parcels and K-Packet.

So with Korea Post, the duty is normally settled in Korea by the sender. The open question is only whether the seller has already built that cost into your price or plans to add it later.

Questions to ask the seller before you pay

Copy these into a message. A seller who ships to the US regularly can answer all of them in two lines.

Is this order shipped with US duties and import fees prepaid (DDP)?
Is the total at checkout the final amount, or can anything be collected from me on delivery?
Which carrier and service will you use?
If the carrier bills me anyway, will you reimburse the charge?
What value and description will be on the customs declaration?
Where was the item manufactured?

Save the reply. If a carrier later asks you for money, a written "no additional charges" from the seller is your evidence in a refund request. The difference between the shipping terms is explained in DDP vs DDU: who actually pays import duties.

How to read "duties included" labels

What the listing says	What it usually means
DDP, duties and taxes paid, no charges on delivery	The seller pays US duty and the carrier's clearance fee. This is the wording you want.
DDU, DAP, duties unpaid, buyer responsible for import fees	You will be billed by the carrier before or at delivery.
Free shipping, shipping and handling included	Says nothing about duty. CBP states that a price that includes shipping and handling does not include duty.
Duties calculated at checkout	Good if the amount is shown as a line item and labeled as final. Ask whether it is an estimate.
Marked as gift, declared at low value	A red flag, not a perk. CBP's FAQ says the gift exemption covers only bona fide gifts and excludes purchased items. A false declaration can get the parcel held, returned or seized.

Also keep in mind that import duty and state sales tax are different things, covered in sales tax vs import duty.

If you get a bill anyway

Check that the bill is real. Fake "customs fee due" texts are common. Do not use the link in the message. Go to the carrier's site yourself and enter the tracking number from your order confirmation.
Compare it with what the seller promised. If the listing or the seller's message said duties were included, send the seller the bill and ask them to pay it or refund you.
Decide before you refuse. A courier generally will not release the goods until the duty is repaid. Refusing the parcel usually means it is returned or abandoned, and you then depend on the seller's refund terms.
Keep everything. Save screenshots of the listing, the seller's messages and the carrier's invoice.

Where The K Drop fits

Orders from The K Drop ship from Korea to the US with tracking, and there are no additional duties or fees for you to pay when the package arrives, because that is handled before shipping.
