Sanctions restrict dealings with specified people, places, sectors or transactions; export controls regulate the transfer of particular items, technology, services or defense articles; tariffs are customs duties charged on imported merchandise. A single shipment can be subject to all three. Paying a tariff does not authorize a controlled export, and an export license does not automatically overcome a sanctions prohibition.

- Sanctions: Is a party, jurisdiction, sector, property or transaction restricted?
- Export controls: What is the item, where is it going, who will receive it, and how will it be used?
- Tariffs: What merchandise is entering the country, what is its origin and customs value, and what duty rate applies?
Sanctions are principally foreign-policy and national-security restrictions. Export controls are transfer controls tied to items and the circumstances of a transfer. Tariffs are border charges that generally allow goods to enter after the importer meets customs requirements and pays the duty.
The examples below use the United States for sanctions and export controls and the World Trade Organization’s general terminology for tariffs. Actual obligations depend on the jurisdictions involved, the current rules and lists, the item’s classification and the transaction facts.

What economic sanctions do
Sanctions target status, conduct and relationships
Economic sanctions can apply to countries or regions, government regimes, industry sectors, companies, individuals, property, banks, vessels and particular transactions. The U.S. Treasury’s Office of Foreign Assets Control (OFAC) describes its role as administering and enforcing economic and trade sanctions against targeted foreign jurisdictions and regimes, as well as individuals and entities.
A sanctions restriction can apply even when the merchandise is ordinary and no physical export takes place. For example, a blocked person may be unable to receive payment, banking services, insurance, software support or other services. A transaction involving blocked property can be prohibited regardless of whether the product itself is controlled for export.
Comprehensive and targeted programs
OFAC programs may be broad, restricting dealings connected with an entire country or region, or targeted at named people and entities. Under a blocking measure, property and property interests subject to U.S. jurisdiction are generally blocked, and U.S. persons generally may not deal with the blocked property without authorization. A designation can therefore stop a transaction at the contracting, financing or payment stage rather than at the border.

A transaction may be restricted because it supports a prohibited sector, involves a blocked financial institution, provides a prohibited service or uses property that is blocked. The fact that goods are physically shipped through a third country does not by itself remove a sanctions issue.
Licenses and exemptions
Some sanctions restrictions permit activity under a general license, while others require a specific license. A general license authorizes defined categories of transactions if its conditions are met. A specific license is an authorization issued for a particular person or set of circumstances. A license is not a blanket approval for unrelated transactions, and its conditions must be followed precisely.

What export controls do
Export controls follow the item and the transfer
Export controls regulate the export, reexport and in-country transfer of specified commodities, software, technology, defense articles and defense services. The U.S. Commerce Department’s Bureau of Industry and Security (BIS) administers the Export Administration Regulations (EAR) for covered commercial and dual-use items. The U.S. Department of State’s Directorate of Defense Trade Controls (DDTC) has jurisdiction over defense articles and defense services under the separate defense-trade regime.
An export-control analysis normally asks four linked questions:

- What is the item? Identify the product, software, technology or service and classify it under the applicable control list or category.
- Where is it going? Consider the destination, any reexport route and any in-country transfer.
- Who will receive or access it? Screen the end user, ownership, intermediaries and other participants.
- How will it be used? Evaluate the stated and suspected end use, including military, nuclear, missile, surveillance or other restricted applications where relevant.
BIS licensing requirements can be triggered by a combination of classification, destination, end user and end use. An item that can be shipped without a license to one destination may require authorization to another, and an otherwise permissible item may be restricted when a prohibited end user or end use is involved.
Exports are broader than a box crossing a border
Depending on the applicable regime, an export or transfer may include releasing technology to a foreign person, sending software electronically, providing controlled technical assistance, reexporting an item from one foreign country to another or transferring an item between foreign persons in-country. A physical shipment is only one possible form of transfer.
Exceptions and licenses
Export regimes may provide license exceptions or exemptions for defined situations, but they are conditional. The exporter must verify eligibility, destination, parties, recordkeeping and any reporting requirements. If no exception applies, a license may be required before the transfer. State-controlled defense articles and services generally follow DDTC rules rather than the EAR, so assuming that a BIS authorization covers a defense article can be a serious error.

What tariffs do
A tariff is a customs duty on merchandise
The World Trade Organization defines customs duties on merchandise imports as tariffs. A tariff is a financial charge assessed when merchandise is imported. It is normally collected from the importer through the customs process, and the goods generally may enter after the importer pays the duty and satisfies other customs requirements.
Tariffs are not usually a prohibition on the underlying product. They change the landed cost and can influence sourcing, pricing and demand. Separate rules may still restrict or prohibit the merchandise for safety, sanctions, export-control, customs or other reasons.
Ad valorem and specific duties
An ad valorem duty is a percentage of the customs value. A 10% rate on merchandise with a customs value of $20,000 would produce a $2,000 duty, assuming the rate and value are correctly established. A specific duty is a fixed amount per unit, weight or quantity, such as an amount per kilogram or per item. A tariff schedule can also combine methods or apply additional measures.
Classification, origin and customs value
Tariff assessment depends on the merchandise classification under the importing country’s tariff schedule, its origin and its customs value. The Harmonized System (HS) provides a common classification framework, but countries apply their own tariff schedules and rates. Preferential trade agreements can reduce or eliminate a rate when origin and documentation requirements are met.
WTO materials distinguish between a legally bound maximum rate and the applied rate actually charged. The applied rate, not merely the bound ceiling, is what determines the duty for the import transaction. Classification decisions, origin claims and valuation can be challenged through the importing country’s customs procedures.

Side-by-side comparison
| Comparison point | Economic sanctions | Export controls | Tariffs |
|---|---|---|---|
| Primary purpose | Foreign-policy, national-security or conduct-based economic pressure | Control proliferation, sensitive technology, defense trade and other security risks | Raise revenue and influence the price or competitiveness of imported merchandise |
| Regulated object | People, entities, jurisdictions, sectors, property, services and transactions | Commodities, software, technology, defense articles, defense services, end users and transfers | Imported merchandise, and less commonly exported merchandise |
| Main trigger | A designation, blocked property, restricted sector, prohibited service or sanctioned transaction | Item classification combined with destination, end user, end use or transfer circumstances | Importation, classification, origin, customs value and the applicable tariff schedule |
| Typical legal effect | Blocks property or prohibits dealings, services, trade or transactions unless authorized | Requires a license, permits a defined exception or prohibits the transfer | Imposes a monetary duty; payment does not itself authorize a prohibited shipment |
| Typical U.S. administrator | OFAC for many financial and party-based sanctions | BIS for EAR items; DDTC for defense articles and services | The importing country’s customs authority |
| Typical remedy | General or specific license, exemption where available, or avoidance of the prohibited activity | License, license exception or exemption where available; otherwise do not transfer | Pay the assessed duty, claim an eligible preference, or challenge classification, origin, value or assessment |
How the three measures can apply to one shipment
Consider a U.S. company shipping network equipment to a distributor abroad. The equipment may be subject to the EAR, so the company must classify it and review the destination, distributor, end user and end use. The distributor or its bank may also be a sanctioned party, creating an OFAC problem even if the equipment is not specially controlled. When the goods enter the destination country, customs determines the HS classification, origin and value and collects any applicable tariff.
The controls do not cancel one another. BIS guidance recognizes that BIS and OFAC can each impose licensing requirements for some sanctioned destinations. The shipment may therefore need both export authorization and sanctions authorization, in addition to customs clearance and payment of any tariff. Paying the duty does not cure an export-control violation, and obtaining an export license does not make a transaction with a blocked person lawful.
A practical compliance sequence
Run the following reviews in parallel rather than treating one approval as a substitute for the others.
1. Screen the sanctions relationships
- Identify the exporter, importer, consignee, end user, agents, freight forwarders, banks, insurers, vessels and other participants.
- Check applicable sanctions lists, ownership information and program rules. Do not stop at a name-only screen when ownership or control rules require further analysis.
- Identify the jurisdictions and sectors connected with the transaction, including transit points and payment locations.
- Determine whether property, services, financing or payments are blocked or restricted.
- Check whether a general license applies. If not, determine whether a specific license is available and whether the transaction must wait for it.
2. Perform the export-control review
- Describe the product, software, technology or service in enough technical detail to classify it accurately.
- Determine whether the item is subject to the EAR, a defense-trade regime or another national export-control system.
- Establish the classification and review the control reasons and destination-based requirements.
- Evaluate the destination, reexport path, end user and end use, including red flags that conflict with the customer’s explanation.
- Determine whether a license is required or whether a narrowly defined exception or exemption is available. Document the basis before shipment or transfer.
3. Complete customs and tariff analysis
- Classify the merchandise under the importing country’s HS or tariff schedule.
- Establish the country of origin using the applicable origin rules and collect supporting records.
- Determine the customs value and any additions or deductions required by local law.
- Check the applied duty rate, additional duties, quotas, trade remedies and any preference program.
- Prepare the customs entry and pay the assessed duty, while retaining records needed for an audit or challenge.
Common mistakes and how to correct them
“The tariff was paid, so the shipment is legal.”
A tariff is only a customs charge. Correct the mistake by completing sanctions and export-control reviews before releasing the goods, technology, services or payment.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute“There is no export issue because the product is not military.”
Many commercial and dual-use items fall under the EAR, and controls can arise from destination, end user or end use rather than military design. Classify the item and assess the transaction facts instead of relying on the product’s marketing description.
Best Value
“A sanctions screen is only needed for the buyer.”
Payment banks, owners, intermediaries, vessels, insurers and service providers can affect the analysis. Build a complete party and ownership map and screen each relevant participant.
“An export license resolves sanctions exposure.”
Export and sanctions authorities regulate different risks. Where both agencies impose requirements, obtain each required authorization and follow each authorization’s conditions.
“A familiar HS code is good enough.”
Small classification differences can change the duty rate, eligibility for a preference or the need for additional measures. Keep the technical description, classification rationale and origin evidence with the customs file.

Which authority answers which question?
- OFAC: whether a U.S.-connected transaction involves a blocked person, property, jurisdiction, sector or prohibited service, and whether a sanctions license is available.
- BIS: whether an item is subject to the EAR, how it is classified and whether destination, end-user or end-use rules require a license.
- DDTC: whether a defense article or defense service falls under the U.S. defense-trade regime and what authorization is required.
- Customs authority: how merchandise is classified, valued and attributed to a country of origin, and what duty or preference applies.
- WTO framework: the international terminology and commitments that distinguish bound tariff ceilings from the rates actually applied by a country.
Companies may also need to consult regulators in the exporting, importing, transit and end-use countries. A U.S. authorization does not replace a foreign country’s import, customs, technology-transfer or sanctions requirements.
Decision guide for readers
Use this quick sequence to identify the starting point:
- Are a person, company, bank, vessel, jurisdiction, sector or transaction restricted? Start with sanctions analysis.
- Is an item, software package, technology, defense article or service being transferred? Start with classification and export-control analysis.
- Is merchandise entering a country? Start with HS classification, origin, customs value and the tariff schedule.
- Are more than one of these answers “yes”? Run the reviews together. The obligations can stack.
What changes over time
Sanctions lists, program rules, export-control classifications, license exceptions, destination controls and tariff rates can change. The applicable result also depends on the transaction date, the specific edition of a rule, the route and the parties’ ownership. Before shipping, transferring technology, accepting payment or filing a customs entry, verify the current lists, notices, schedules and license conditions with the responsible authorities or qualified counsel.
