International Ocean and Air Freight Made Simple
September 18, 2026A tariff bill on an international shipment rarely arrives when you expect it, and it almost never matches the number you calculated at checkout. One entry gets held for a duty payment you didn’t budget, another clears with a fee that wasn’t on last quarter’s invoice, and suddenly your landed cost model needs a rewrite. That’s the reality of importing into the U.S. right now.
We’ve watched tariff policy shift several times over the past year, from new reciprocal tariff rates to the removal of the de minimis exemption for low-value shipments. Each change touches a different part of the shipment, whether that’s the HTS code you declare, the customs value you report, or which party is contractually on the hook for duties under your Incoterms. The total cost of landing a shipment in the U.S. now depends on origin, classification, and entry timing as much as it depends on freight rates.
None of this needs to be mysterious. Once you understand how duties, taxes, and fees stack on a single import, you can build tariff exposure into your pricing instead of getting surprised by it at the border. We’ll walk through how the current rules apply at the shipment level, and where to check for the latest changes before you file.


How U.S. Tariff Changes Affect Your Shipment and Total Cost
Every U.S. tariff change eventually shows up as a line item on a specific shipment, tied to a specific HTS code and country of origin. The rate structure that applies to your goods can include a base Most Favored Nation duty, a reciprocal tariff, and a Section 232 or Section 301 layer, depending on the product and where it was made. Getting the landed cost right means checking each of these layers against your actual commercial invoice, not against a general headline about “new tariffs.”
What Is the Difference Between a Tariff, Duty, and VAT?
A tariff and a customs duty are the same charge, imposed by the U.S. government on imported goods based on the product’s harmonized code, country of origin, and declared value. Value-added tax is a separate, consumption-based tax applied in many countries at each stage of production, and it’s distinct from the sales tax charged domestically at checkout, as UPS explains in its tariff basics guide. The U.S. does not apply a federal VAT, so for U.S.-bound shipments, your main charges are duties, the merchandise processing fee, and the harbor maintenance fee for ocean freight.
Which Party Pays Import Charges Under Incoterms?
The Incoterm on your commercial invoice determines who pays duties and taxes, not the carrier or the customs broker. Under Delivered Duty Paid, the seller covers duties and taxes before the goods reach the buyer; under Delivered At Place, the buyer typically becomes the importer of record and pays duties and taxes on arrival. We always recommend confirming the Incoterm in writing before a shipment leaves the origin country, because that single term decides who gets the customs bill.
How Are Import Duties Calculated From an HTS Code and Customs Value?
Import duties are calculated by multiplying the customs value of the goods by the tariff rate assigned to their 10-digit HTS code. The Harmonized Tariff Schedule published by the U.S. International Trade Commission lists the applicable rate for every classification, and a step-by-step breakdown of duty calculation shows how the base reciprocal tariff, Section 232, and Section 301 rates apply on top of the standard rate for a given HTSUS code. Declared value matters here too: understating it to reduce duty exposure is a customs violation, and CBP can penalize both the importer of record and the shipper.
Why Country of Origin Matters More Than the Shipping Route
Country of origin, not the last port a shipment passed through, determines which tariff layers apply. Rules of origin are the criteria CBP uses to decide where a product was substantially transformed, and they exist specifically to prevent transshipment, routing goods through a third country to disguise their true origin, as UPS notes in its guidance on rules of origin. Goods from Vietnam, Thailand, or Malaysia that were substantially made in a tariffed country can still be assessed at the higher rate if CBP determines the origin claim doesn’t hold up.
Which U.S. Tariff Layers Can Apply to One Import?
A single product can carry multiple tariff layers at once. Reciprocal tariffs generally stack on top of Most Favored Nation duties for most countries except the European Union, though reciprocal tariffs do not stack with Section 232 tariffs, and some products qualify for exclusions, according to UPS’s tariff FAQ. Depending on the product, you may also see IEEPA tariffs layered in under the International Emergency Economic Powers Act, or additional duties under the Trade Act of 1974. Because these authorities interact differently by product and origin, we recommend running your specific HTS code through a current tariff tracker before assuming a rate.
How Section 232 and Section 301 Measures Affect Key Product Categories
Section 232 tariffs target national-security-linked sectors like steel imports, aluminum, vehicles, aircraft, and vessels, while Section 301 tariffs have historically focused on China tariffs across categories like machinery, semiconductors, and consumer goods. In July 2026, new Section 301 tariffs of 10 to 12.5% took effect on imports from 60 economies, according to reporting on the July 2026 tariff changes, reshaping costs for apparel, textiles, footwear, furniture, carpets, plastics, rubber, and tools. Pharmaceuticals, critical minerals, and fertilizers have received different treatment in various proposals, so it’s worth checking the current status for your specific category rather than assuming a blanket rate applies across an entire industry.


What the End of the De Minimis Exemption Means for Low-Value Shipments
The de minimis exemption that once let shipments under $800 enter duty-free is gone. An executive order suspended Section 321 de minimis treatment for all low-value shipments to the U.S. effective August 29, 2025, meaning every import now faces applicable duties and taxes regardless of value, origin, or how it’s routed, as detailed in UPS’s explanation of the de minimis changes. Goods shipped through the international postal system are assessed either an ad valorem duty based on the effective tariff rate, or a specific duty ranging from $80 to $200 per item depending on country of origin. For ecommerce sellers who built pricing around duty-free small parcels, this is the single biggest change to plan around in 2026.
What Documents Are Needed for Customs Clearance?
Clean customs clearance starts with a complete commercial invoice: product description, country of origin, the 10-digit HTS code, and quantity and value of the goods. Formal entries (shipments valued over $2,500) also require an importer tax ID, either an EIN or Social Security Number, and shipments of a single commodity valued over $2,500 need an Electronic Export Information filing submitted through CBP’s Automated Commercial Environment, per UPS’s clearance documentation checklist. Missing or inaccurate HTS codes are one of the most common reasons a shipment gets held at the border, so we double-check classification before goods leave the warehouse, not after.
How Trade Agreements Can Reduce Duty Liability
Trade agreements like USMCA and CAFTA-DR can reduce or eliminate duty liability for goods that meet the agreement’s rules of origin. Qualifying under a free trade agreement isn’t automatic: you need supporting documentation proving where the inputs came from and how much value was added in the qualifying country. For businesses sourcing from Mexico, Canada, or Central America, this is worth verifying on every shipment, since misclassifying origin can trigger duty assessments plus penalties later.
How Businesses Can Manage Tariff-Driven Cost Increases Legally
Legal ways to manage tariff costs include duty drawback for re-exported goods, sourcing shifts to countries with lower applicable rates, and consolidating shipments to reduce per-unit brokerage fees. Duty drawback does have limits: additional duties imposed under recent executive orders on China, Mexico, or Canada are not eligible for drawback, per UPS’s guidance on drawback exclusions. We’ve also seen businesses succeed by reviewing HTS classifications with a broker, since some products qualify for a lower duty rate under a more precise 10-digit code than the one they’d been using by default.
How Tariffs Reshape Freight Demand, Routes, and Delivery Pricing
Tariff changes shift freight volumes between trade lanes as importers move sourcing away from higher-tariff countries, which in turn affects capacity and pricing on the lanes gaining that volume. The 2025-2026 escalation in China-U.S. tariffs reshaped transpacific freight economics, pushing some importers toward Southeast Asian suppliers and changing demand patterns on those routes, according to an analysis of China-U.S. tariff effects on freight. Freight costs and tariff costs move somewhat independently: your per-container ocean rate might drop while your duty bill rises, so tracking them as separate line items in your landed cost model gives a clearer picture than watching one number. If you’re building out an international shipping strategy for the year ahead, understanding what you need to know about international shipping alongside current tariff exposure helps you avoid surprises on both fronts.
When to Use a Customs Broker and Monitor Official Updates
A licensed customs broker earns their fee on any shipment involving formal entry, multiple tariff layers, or a product category under active trade action. Brokers file entries through CBP’s ACE platform, verify HTS classification, and catch documentation gaps before they turn into clearance delays. Because rates and exclusions change by entry date, we recommend checking the Harmonized Tariff Schedule directly, following CBP’s published guidance, or working with a broker who monitors a live tariff tracker rather than relying on a rate you confirmed months ago.

Frequently Asked Questions
Are tariffs charged on shipping costs?
Tariffs are calculated on the customs value of the goods, generally the price paid for the product, not the freight or insurance cost, though this depends on the valuation method used on the entry. Some entries do include freight and insurance in the dutiable value depending on the terms of sale, so it’s worth confirming with your broker how your specific shipment is valued.
Who pays tariffs on an international package?
The party responsible for tariffs is determined by the Incoterm on the shipment, not by the carrier. Under Delivered Duty Paid, the seller pays; under terms like Delivered At Place, the buyer or importer of record typically pays duties and taxes on arrival, as outlined in UPS’s explanation of who pays tariffs.
Are orders under $800 still exempt from U.S. import duties?
No. The de minimis exemption for shipments under $800 was suspended effective August 29, 2025, so all U.S. imports now face applicable duties and taxes regardless of declared value, origin, or shipping method. Postal shipments are assessed either an ad valorem rate or a specific duty of $80 to $200 per item depending on the country of origin.
What are the current U.S. tariff rates for my product?
Current rates depend on your product’s 10-digit HTS code and country of origin, and they can include a Most Favored Nation base rate plus reciprocal, Section 232, or Section 301 layers. Check the Harmonized Tariff Schedule for your specific classification, or confirm final treatment with a licensed customs broker, since rates change by entry date and exclusion status.
Can UPS or another carrier collect tariffs at delivery?
Yes. Carriers including UPS collect duties and taxes on behalf of CBP when a shipment clears customs, and UPS tariff payment is typically billed to the shipper or consignee based on the shipment’s billing terms. Some businesses use a UPS tariff calculator or the UPS Global Checkout tool to estimate UPS tariffs and total landed cost before a customer completes checkout.
How can I estimate the landed cost of an import shipment?
Estimate landed cost by adding the product price, freight and insurance, applicable duty layers based on HTS code and origin, the merchandise processing fee, and any harbor maintenance fee for ocean shipments. Tools like a guaranteed landed cost calculator or a customs broker’s quote can pull these figures together, but the estimate is only as accurate as the HTS classification and customs value you provide.
