A single shipment can face all three. Paying a tariff does not authorize a controlled export, and an export license does not automatically permit dealings with a sanctioned party.
At a glance: three tools, three different questions
The fastest way to distinguish the tools is to ask what the rule is aimed at. Sanctions start with a person, organization, jurisdiction, sector or transaction. Export controls start with an item and then examine where it is going, who will receive it and how it will be used. Tariffs start when merchandise crosses a customs border and determine the duty due.

| Tool | What it targets | Typical trigger | Legal effect | Common U.S. administrator | Reader’s test |
|---|---|---|---|---|---|
| Economic sanctions | Countries, regions, sectors, entities, individuals, property and transactions | A designation, prohibited dealing, restricted jurisdiction or covered transaction | Blocks property, prohibits dealings, restricts services or trade, or imposes an embargo; an authorization may be available | U.S. Treasury’s Office of Foreign Assets Control (OFAC) | Is this party, place, sector, property or transaction restricted? |
| Export controls | Commodities, software, technology, defense articles and defense services, end users and destinations | An export, reexport or in-country transfer involving a controlled item, destination, end user or end use | Requires a license, limits a transfer or prohibits it | U.S. Commerce Department’s Bureau of Industry and Security (BIS) for items under the EAR; State Department DDTC for defense articles and services | What is the item, where is it going, who receives it and how will it be used? |
| Tariffs | Imported merchandise (and, less commonly, exported merchandise) | Importation under a customs tariff schedule | Adds a customs duty or tax payable at importation; goods generally may enter after payment and other customs requirements are met | The importing country’s customs authority | What is the product’s HS classification, origin, customs value and duty rate? |
OFAC describes its role as administering and enforcing “economic and trade sanctions against targeted foreign jurisdictions and regimes, as well as individuals and entities” (U.S. Treasury, 2024). BIS describes the Export Administration Regulations (EAR) as regulating “the export, reexport, and transfer (in-country) of items,” including commodities, software and technology. The World Trade Organization (WTO) states that “customs duties on merchandise imports are called tariffs.” Those descriptions capture the basic dividing line.
Economic sanctions: restrictions aimed at parties, places and conduct
What sanctions regulate
Sanctions are status- or conduct-based restrictions. They can apply to a named individual, company, bank, vessel or government; to a country or region; to a sector such as finance or energy; to property; or to a transaction or service. The regulated object does not have to be a sophisticated product, and there does not have to be a physical export. An ordinary consumer item can become unusable in a transaction if one party or the payment channel is blocked.
#1 Best Overall
OFAC programs may be comprehensive, covering broad dealings with a jurisdiction or region, or targeted, naming particular persons and entities. A blocked person’s property and property interests generally may not be dealt with by U.S. persons unless an authorization applies. A restriction can also reach services, financing, insurance, brokering or other conduct even when no goods leave the country.
Blocking versus a trade restriction
A blocking rule normally freezes property under U.S. jurisdiction and bars U.S. persons from dealing in it. Other sanctions prohibit narrower categories of conduct, such as providing a particular service to a sector or engaging in specified transactions involving a jurisdiction. The exact program text matters: a country-based program, a list-based designation and a sectoral restriction can impose different limits.
Licenses and other authorizations
Sanctions programs can include general licenses, which authorize a defined class of transactions, and specific licenses, which authorize a particular applicant’s transaction. An authorization is not a blanket clearance for every party, product or payment method. It applies only within its stated scope, time period and conditions. If no authorization covers the conduct, the transaction must be stopped or redesigned.

Illustrative sanctions scenario
A U.S. company wants to sell an ordinary industrial pump. The pump itself is not specially controlled, but the proposed buyer is a blocked entity. Screening the buyer, its beneficial owners, the bank and any freight or insurance providers can reveal a sanctions problem before an export-control analysis begins. The item’s ordinary nature does not remove the party-based restriction.
Export controls: item-and-transfer rules
The four questions that drive an export-control review
Export controls are transaction-specific. The analysis normally turns on four connected facts:
Rank #2
- Item: Identify the commodity, software, technology, defense article or service and classify it under the applicable regime.
- Destination: Determine the country or territory of the export, reexport or in-country transfer and any intermediate locations.
- End user: Identify the recipient, including relevant ownership, intermediaries and parties who will access the item.
- End use: Determine how the item will be used, including sensitive military, proliferation or other restricted uses specified by the applicable rules.
A change in any one of those facts can change the license result. A product that may move to one destination can require authorization for another; software supplied to a distributor may raise different questions when the distributor intends to make it available to additional users.
EAR items and defense jurisdiction
BIS administers the EAR for covered commercial and dual-use commodities, software and technology. The EAR can reach exports from the United States, reexports from one foreign country to another and certain in-country transfers. The State Department’s Directorate of Defense Trade Controls (DDTC) has jurisdiction over defense articles and defense services under the separate defense-trade regime. Determining which agency has jurisdiction is an early step, not something to assume from the product’s marketing name.

An export-control rule may require a license, allow a defined license exception, impose a limitation or prohibit the transfer outright. A license exception is available only when every stated condition is met, such as eligible destinations, users, documentation and recordkeeping. A general assumption that an item is “commercial” is not a substitute for classification and destination analysis.
Illustrative export-control scenario
A manufacturer ships specialized encryption software to a foreign reseller. The compliance issue is not settled by the software’s price or by the fact that the reseller is a private company. The manufacturer must classify the software, determine the destination and any onward destinations, identify the reseller and ultimate users, and assess the intended use. The result could be no license, a license exception or a license requirement depending on those facts.
Tariffs: a charge collected when merchandise is imported
What a tariff does
A tariff is a customs duty on merchandise. It changes the landed cost and generally raises revenue or protects domestic industries; it does not, by itself, identify a buyer as prohibited or make a technology transfer lawful. The importer normally pays the assessed duty, along with any other applicable customs charges, before or as the goods are released under the importing country’s procedures.
Rank #3
How duty is calculated
Most tariff schedules use one of two basic methods:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Ad valorem duty: a percentage of the customs value. A 5% rate on merchandise valued at $100,000 produces a $5,000 duty, assuming the stated value and rate are accepted by customs.
- Specific duty: a fixed amount per unit, weight or other quantity. The total depends on the measured quantity rather than solely on the invoice value.
Some schedules combine the methods or apply additional measures. The decisive inputs are the product’s Harmonized System (HS) classification, country of origin, customs value and any preference or special program that applies.
Bound rates versus applied rates
The WTO distinguishes a legally bound ceiling from the applied rate actually charged at the border. A country may have committed not to exceed a bound rate while collecting a lower applied rate under its current tariff schedule or a preference program. Importers must use the current schedule for the relevant country, product and date rather than relying on a bound maximum.
Illustrative tariff scenario
A lawful household appliance enters a country and is correctly classified under that country’s tariff schedule. Customs assesses an ad valorem duty based on the accepted customs value. Once the importer satisfies customs requirements and pays the duty, the merchandise can generally enter. Nothing about that payment answers whether the buyer is sanctioned or whether embedded software is subject to export controls.
How the tools differ by purpose, object and remedy
| Comparison point | Sanctions | Export controls | Tariffs |
|---|---|---|---|
| Primary purpose | Foreign-policy or national-security pressure; prevention of dealings with prohibited parties or conduct | Security, nonproliferation, defense and strategic control over sensitive items and transfers | Revenue, price policy and trade protection at the border |
| Regulated object | Party, jurisdiction, sector, property, service or transaction | Item, technology, defense article or service plus destination, end user and end use | Merchandise identified by HS classification, origin and customs value |
| When the rule is triggered | Designation, restricted jurisdiction, blocked property or covered conduct | Export, reexport or in-country transfer of a covered item | Importation (and less commonly exportation) under a tariff schedule |
| Typical legal result | Block, prohibit or restrict dealings; an authorization may be possible | License requirement, limitation, exception or prohibition | Monetary duty; goods may enter after customs compliance and payment |
| Primary decision-maker | OFAC or another sanctions authority, depending on the program | BIS, DDTC or another export-control authority, depending on jurisdiction | Customs authority in the importing country |
| Typical remedy or path forward | General or specific license, exemption where available, or removing the prohibited party or conduct | Correct classification, license exception, license application or a different item, destination, user or end use | Correct classification, origin or valuation; claim an eligible preference; pay the assessed duty or challenge it through customs procedures |
Can one shipment face sanctions, export controls and a tariff?
Yes. The regimes address different legal questions and can operate at the same time. BIS guidance recognizes that BIS and OFAC can each maintain license requirements for transactions involving some sanctioned destinations. The same shipment can also owe a customs duty based on its merchandise classification and origin.

Why the approvals do not substitute for one another
- A tariff is not permission to export. Paying customs duty does not cure a prohibited export, reexport, transfer or end use.
- An export license is not sanctions clearance. A BIS or DDTC authorization does not automatically permit a U.S. person to deal with a blocked party, blocked property or prohibited payment.
- Sanctions screening is not tariff classification. A clean party screen does not establish the correct HS code, origin or customs value.
Combined example
Consider a U.S. seller shipping a dual-use sensor to a foreign distributor. The sensor may require a BIS review based on its classification, destination and end use. The distributor, its owners, the bank and the freight provider must be screened under applicable sanctions programs. When the sensor enters the destination country, the importer must classify it under that country’s HS schedule, establish origin and customs value, and pay the resulting duty. Each review can produce a different answer, and all three answers are needed before completion.

Run the following checks in parallel rather than treating them as one approval.
1. Screen the sanctions exposure
- List every relevant party: seller, buyer, beneficial owners, agents, banks, insurers, freight forwarders, vessels and other intermediaries.
- Identify all jurisdictions involved, including transit points and places where services or payments occur.
- Check the current OFAC lists and the rules for the applicable sanctions program.
- Determine whether property, services, payments or other conduct are blocked or restricted.
- Check whether a general or specific license covers the exact parties, activity, timing and payment path. Preserve the conditions and records required by that authorization.
2. Review export controls
- Describe the item precisely, including hardware, components, firmware, software, technical data and services supplied with it.
- Determine whether the item is subject to the EAR, the defense-trade rules administered by DDTC or another regime.
- Classify the item using the applicable control structure and record the rationale.
- Map the full movement: export, reexport, in-country transfer, remote access and any onward release.
- Identify the end user and end use, then check destination-based, user-based and use-based restrictions.
- Decide whether no authorization is required, a license exception is available, a license application is needed or the transaction is prohibited.
3. Complete the customs and tariff review
- Classify the merchandise under the importing country’s current HS and tariff schedule.
- Establish country of origin under the applicable origin rules, including any substantial-transformation analysis required by that jurisdiction.
- Determine the customs value and the quantity or measurement used for a specific duty.
- Check the current applied rate, preference programs, additional duties and documentation requirements.
- Calculate the expected duty, file accurate entry information and pay or challenge the assessment through the customs process.
Keep the three workstreams tied to the same transaction record. A change in buyer, bank, destination, product configuration, end use, origin or shipment route can require all three analyses to be revisited.
Common misconceptions and the correct test
“Sanctions are just export bans.”
No. Sanctions can block a person, entity, property, sector, service or transaction even when the item is ordinary and no physical export occurs. Start with the parties and conduct, not the product catalog.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problems“If the customer is not on a list, the export is unrestricted.”
No. Export controls can apply because of the item, destination or end use. Party screening is necessary for sanctions and user-based export restrictions, but it does not replace classification.
Best Value
“A tariff means the goods are prohibited.”
No. A tariff is normally a charge. The goods may enter after customs compliance and payment, although separate sanctions, export controls, quotas, product standards or other measures could still restrict the transaction.
“An export license covers the payment and the buyer.”
No. Export authorization and sanctions authorization come from different legal authorities and address different risks. A payment to a blocked bank or a dealing with blocked property can remain prohibited.
“The WTO rate is the amount the importer will pay.”
Not necessarily. WTO commitments include bound ceilings, while customs collects the applied rate in force for the product, origin and date. The importer must consult the current national schedule and any preference rules.
Who is responsible for each decision?
For many U.S.-related financial and party restrictions, OFAC is the key sanctions authority. BIS administers the EAR for covered commercial and dual-use items, while DDTC handles defense articles and defense services within its jurisdiction. Customs authorities in the importing country determine tariff classification, origin, valuation and collection. Other agencies can have authority in specialized cases, so the product and transaction should be mapped before selecting the regulator.
Keeping the analysis current
Sanctions lists, program rules, license exceptions, destination controls and tariff schedules can change. The U.S. examples above explain the concepts; they are not a universal rulebook for every country. Before committing a transaction, verify the current lists, notices, tariff schedule, classification, origin rules, licensing conditions and effective dates for the actual destination and route.
The operational rule to remember
Use three separate questions: Who and what conduct are restricted? That is the sanctions inquiry. What item is moving, to whom, where and for what use? That is the export-control inquiry. What merchandise is entering, from where and at what value? That is the tariff inquiry. Treating those questions independently—and then checking where their answers overlap—is the reliable way to avoid assuming that one approval solves a different legal problem.
