How to Stop Tariffs Turning a Profitable Export into a Loss: 7 Checks Before You Ship

The order looks profitable. The customer is ready. The price has been agreed.

Then the shipment encounters a new tariff, an unexpected customs charge, a compliance problem or a freight surcharge. Suddenly, the margin you thought you had has disappeared.

That risk is becoming harder to ignore.

The World Trade Organization forecasts that merchandise trade growth will slow from 4.6% in 2025 to 1.9% in 2026. It also estimates that persistently high energy prices could reduce growth to 1.4%. Meanwhile, only 72% of world trade was being conducted under standard most-favoured-nation tariff arrangements by February 2026—evidence of a more fragmented and less predictable trading environment.

International trade is still growing. But the margin for error is shrinking.

Before accepting your next international order, carry out these seven checks.

1. Classify the product correctly

Every internationally traded product should have a Harmonized System—or HS—classification. That code helps determine:

• The applicable tariff

• Import restrictions

• Licensing requirements

• Rules of origin

• Required customs documentation

A product described commercially as a “machine component” could fall into several different tariff categories depending on its material, function and intended use.

Do not copy the HS code from an old invoice or accept one supplied by the buyer without checking it. Confirm the classification with your customs adviser or the relevant customs authority—and record who made the determination.

A small classification error can change the duty payable or cause the shipment to be detained.

2. Establish the product’s real origin

Country of origin is not necessarily where the product was shipped from. Nor is it always where the final assembly took place.

Origin can depend on where the product underwent its last substantial transformation, the proportion of locally sourced materials and the specific rules attached to a trade agreement.

This matters because origin can determine whether your product qualifies for a reduced tariff—or faces an additional one.

Verify:

• Where the principal components were manufactured

• What processing occurred in each country

• Whether preferential rules of origin apply

• What evidence the importer must retain

• Whether a certificate or declaration of origin is required

Never promise tariff-free treatment until eligibility has been confirmed.

3. Calculate the full landed cost

The sales price is not the customer’s real cost.

Build a landed-cost estimate incorporating:

• Product price

• Freight and insurance

• Tariffs and customs duties

• Import VAT or sales taxes

• Customs brokerage

• Inspection and certification fees

• Port, handling and storage charges

• Carbon-related costs

• Currency conversion and payment fees

Then model at least three scenarios: expected cost, moderate disruption and severe disruption.

This is particularly important when transport or energy prices are unstable. The WTO estimates that prolonged energy-price pressure could remove 0.5 percentage points from global merchandise trade growth in 2026 while increasing transport, insurance and production costs.

A transaction that works only under the most optimistic assumptions is not a robust transaction.

4. Choose the Incoterm commercially—not habitually

Incoterms determine where responsibility, cost and risk move between buyer and seller. They do not determine ownership or payment—and they should never be selected simply because “that is what we normally use.”

Ask:

• Who is best equipped to arrange transport?

• Who can obtain insurance most efficiently?

• Who understands the destination’s customs requirements?

• Who will pay duties and import taxes?

• At what point should risk transfer?

• Does the agreed payment timing match that transfer?

DDP may make purchasing easier for the customer, but it can expose the exporter to unfamiliar taxes and import obligations. EXW may appear safer for the seller, yet provide too little control over export clearance and shipping evidence.

Choose the term that matches the actual transaction.

5. Check the regulatory requirements before pricing

Tariffs are only one source of additional cost.

Product standards, sanctions, export controls, labelling rules, environmental reporting and licensing requirements can determine whether goods are allowed to move at all.

The EU’s Carbon Border Adjustment Mechanism entered its definitive regime on 1 January 2026. It now creates authorisation, emissions-reporting and financial obligations for importers of covered goods—including iron and steel, aluminium, cement, fertilisers, electricity and hydrogen.

Even when your product is not directly covered, customers may increasingly request emissions and supply-chain data.

Compliance is therefore no longer a final documentation exercise. It must be assessed before the price is agreed.

6. Agree the documents—and the data—upfront

International transactions frequently fail because different parties create their own versions of the same information.

The ICC Digital Standards Initiative identified 36 key trade documents containing approximately 200 core data elements, around 50 of which are shared across multiple documents.

Re-entering those details creates avoidable discrepancies.

Before shipping, agree:

• Which documents are required

• Who creates each document

• Who approves it

• Which data fields must match

• When each document must be available

• Who can amend the information

Create the transaction record once, then use the same approved data to generate every subsequent document.

7. Manage the transaction digitally from beginning to end

Emailing PDFs is not digital trade. It is paper trade transmitted electronically.

A genuinely digital transaction gives the buyer, seller and authorised service providers access to the same structured information, documents, responsibilities and status.

The commercial case is significant. The OECD estimates that improved border processes have reduced trade costs by up to 5% over the past decade—and that ambitious additional reforms could reduce them by as much as another 12 percentage points.

This is where platforms such as iTradeDigital can make a tangible difference: guiding the parties through the transaction, helping them select the appropriate Incoterm, generating consistent documentation and providing a shared record of what has been agreed, completed and paid.

You cannot eliminate tariffs, geopolitical disruption or regulatory change.

But you can prevent them from catching you by surprise.

In today’s international trade environment, profitability is no longer determined when the order is won. It is protected—or lost—in how the transaction is executed.
