Landed cost = product cost + shipping + duties + taxes + brokerage + insurance. That's the formula. But most ecommerce sellers only account for the first two and then wonder why their international margins are razor-thin (or negative).
Cross-border shipping in 2026 is more expensive than it was even a year ago. The U.S. killed its $800 de minimis exemption in August 2025. The EU is eliminating its 150 EUR duty-free threshold in July 2026. If you sell internationally and haven't recalculated your landed costs recently, you're probably underpricing.
The Landed Cost Formula (Step by Step)
Every international order has these cost layers. Miss one and your margin calculation is wrong.
Step 1: Product cost. What you paid for the item (COGS). Straightforward.
Step 2: International shipping. The carrier fee to move the package across borders. This includes first-mile, freight (air or sea), and last-mile delivery. International shipping typically runs 2-5x the cost of domestic shipping for the same weight.
Step 3: Customs duties. A tax charged by the destination country based on the product type, declared value, and country of origin. Duty rates typically range from 0% to over 25% depending on the product's HS (Harmonized System) code.
Step 4: Import taxes (VAT/GST). Most countries charge a value-added tax on imports. The EU charges 17-27% VAT (varies by member state). The UK charges 20% VAT. Australia charges 10% GST. Canada charges 5% GST.
Step 5: Brokerage fees. The customs broker who clears your shipment charges $5-$50+ per shipment. Some carriers include this; others don't.
Step 6: Insurance (optional but recommended). Typically 1-3% of declared value. Worth it for high-value items.
Landed Cost Example: Shipping a $50 Product from the U.S. to the EU
Let's walk through a real calculation. You sell a product that costs you $20 (COGS) and retails for $50. You're shipping from the U.S. to Germany.
| Cost Component | Amount | How It's Calculated |
|---|---|---|
| Product cost (COGS) | $20.00 | Your supplier/manufacturing cost |
| International shipping | $12.00 | Carrier rate for weight/dimensions |
| Customs duty (8% on $50 value) | $4.00 | Based on HS code and declared value |
| VAT (19% Germany, on value + shipping + duty) | $12.54 | 19% x ($50 + $12 + $4) |
| Brokerage fee | $5.00 | Customs clearance processing |
| Insurance (2% of value) | $1.00 | 2% of $50 declared value |
| Total Landed Cost | $54.54 |
Your landed cost ($54.54) already exceeds the retail price ($50). You're losing $4.54 per order before payment processing fees.
This is how international sales silently destroy margins. The product looks profitable at the domestic level, but the cross-border math tells a completely different story.
De Minimis Thresholds by Country (2026 Update)
The de minimis threshold is the value below which goods enter a country duty-free. These thresholds are shrinking globally, and two major changes in 2025-2026 have reset the economics for a huge number of cross-border sellers.
| Country/Region | De Minimis (Duty-Free Threshold) | 2025-2026 Changes |
|---|---|---|
| United States | Suspended (was $800) | Eliminated Aug 29, 2025. All imports now subject to duties. |
| European Union | 150 EUR (ending July 2026) | Flat 3 EUR customs duty per consignment starting July 1, 2026 |
| United Kingdom | 135 GBP | No changes announced |
| Australia | $1,000 AUD | One of the highest thresholds globally |
| Canada | $20 CAD | Very low; almost all imports incur duty |
| China | No de minimis | Duty charged on all ecommerce imports |
| Russia | 200 EUR / 31 kg | Both value and weight limits apply |
The U.S. de minimis change is the biggest shift in cross-border ecommerce in years. Before August 2025, shipments valued at $800 or less entered the U.S. duty-free. That's how Shein, Temu, and thousands of smaller sellers shipped directly from China without paying duties (per Easyship and CBP documentation). That door is now closed.
The EU change coming in July 2026 will add a flat 3 EUR customs duty per consignment on low-value goods, replacing the current 150 EUR exemption (European Commission, 2025). It's not massive per order, but it adds up across thousands of shipments.

HS (Harmonized System) codes classify every product in international trade. Your product's HS code determines the duty rate, and getting it wrong can mean overpaying by thousands of dollars (or getting hit with penalties).
A cotton t-shirt and a polyester t-shirt have different HS codes and different duty rates. A phone case classified as a "plastic article" pays a different rate than the same case classified as an "electronic accessory."
I think most small ecommerce sellers get their HS codes wrong because they guess rather than look them up. Tools like Zonos and the U.S. International Trade Commission's Harmonized Tariff Schedule database let you search for the correct code by product description. Take the 10 minutes to do it right. A wrong HS code can trigger audits, delays, and retroactive duty charges.
DDP vs. DDU: Who Pays the Duties?
Two shipping terms you need to know:
DDP (Delivered Duty Paid): You pay all duties and taxes upfront. The customer sees one total price at checkout with no surprise charges on delivery. This is better for customer experience but requires you to estimate duties accurately.
DDU (Delivered Duty Unpaid): The customer pays duties and taxes when the package arrives. This is simpler for you but leads to refused deliveries and angry customers who didn't expect a $15 charge at their doorstep.
For DTC brands focused on customer experience, DDP is almost always the better choice. Yes, it's more complex. You need a duty estimation tool at checkout (Shopify has built-in support; tools like Zonos and DHL's duty calculator integrate easily). But the reduction in cart abandonment and customer complaints usually pays for the effort.
Shopify's international pricing features now support automatic duty and tax estimation at checkout for merchants on Advanced and Plus plans (Shopify Help Center, 2026). This makes DDP much more accessible than it was even 2 years ago.
2026 Tariff Changes That Affect Your Costs
The tariff landscape shifted significantly in early 2026. On February 20, 2026, the U.S. Supreme Court invalidated tariffs imposed under IEEPA. A new temporary 10% import duty under Section 122 of the Trade Act of 1974 became effective February 24, 2026.
What this means for ecommerce sellers: the specific rates you were paying may have changed. Products from China, in particular, have seen fluctuating duty rates over the past 18 months. If you haven't rechecked your landed costs since early 2026, do it now. Even a 2-3% shift in duty rates can flip an international SKU from profitable to unprofitable.
Best practice: integrate a real-time duty estimation tool (Zonos, Avalara, or DHL's calculator) that updates automatically as tariff rates change. Manual spreadsheet calculations go stale the moment a new tariff is announced.
Reducing Cross-Border Costs
You can't avoid duties and taxes. But you can minimize the cost structure around them:
- Consolidate shipments. Sending 50 units in one container is far cheaper per unit than 50 individual parcels.
- Use the right Incoterms. DDP vs. DDU changes who bears the cost, which affects pricing strategy and cash flow.
- Warehouse locally. If you sell enough volume in a market, storing inventory locally eliminates per-order customs clearance. Amazon FBA in the EU or UK handles this for sellers on those platforms.
- Classify products correctly. Some HS codes have lower duty rates for functionally similar products.
- Take advantage of trade agreements. Products manufactured in countries with free trade agreements may qualify for reduced or zero duties.
Frequently Asked Questions
What is landed cost in ecommerce?
Landed cost is the total price of getting a product from your supplier to your international customer's door. It includes product cost, shipping, customs duties, import taxes (VAT/GST), brokerage fees, and insurance. It's the number you need to calculate true profit on cross-border orders.
What is the de minimis threshold?
It's the maximum shipment value that enters a country duty-free. The U.S. suspended its $800 threshold in August 2025, so all imports now face duties. The EU is eliminating its 150 EUR threshold in July 2026. Australia's threshold ($1,000 AUD) remains one of the highest globally.
How are customs duties calculated?
Duties are based on three things: the product's HS code (classification), the declared value of the shipment, and the country of origin. Rates typically range from 0% to 25%+. The duty is applied to the customs value, which usually includes the product cost plus shipping and insurance.
What changed with U.S. de minimis in 2025?
As of August 29, 2025, the U.S. suspended duty-free treatment for shipments under $800. All imports now face full duties and taxes regardless of value. This primarily affects direct-from-China sellers and businesses that relied on the exemption to keep prices low.
Should I use DDP or DDU for international orders?
DDP (Delivered Duty Paid) is better for customer experience since there are no surprise fees on delivery. It requires duty estimation at checkout but reduces cart abandonment and refused deliveries. DDU is simpler for you but often leads to angry customers and uncollected packages.
