International trade and customs regulation: legal keys for global companies

International trade allows companies to sell, buy, distribute, manufacture or invest in different markets, but it also requires them to operate within an increasingly complex legal framework. International sanctions, export controls, tariffs, distribution agreements, Incoterms and foreign investment screening can affect any cross-border transaction.

In this context, a lawyer specialized in international trade must understand both the business logic and the rules governing the movement of goods, services, capital and technology between countries.

For those who want to build a career in this field, ISDE’s Master in International Law, Foreign Trade and International Relations offers training connected to legal advisory in international transactions, global commercial relations and cross-border regulation.

International sanctions and export controls: what companies need to know

International sanctions and export controls are tools used by States and international organizations to restrict certain transactions with specific countries, companies, sectors or individuals.

For a company, this means that closing a sale or signing a contract is not enough. Before operating in certain markets, it must check whether any restrictions may affect:

• The destination country.
• The client or counterparty.
• The product or technology exported.
• The end use of the goods.
• The financial institution involved.
• Transport or intermediaries.
• Customs documentation.
• Required licences.

Non-compliance can lead to financial penalties, blocked transactions, loss of licences, reputational damage and even criminal consequences in certain cases.

For this reason, companies exporting sensitive products, technology, software, industrial components or dual-use goods need review protocols, internal controls and specialized legal advice.

Incoterms and international distribution agreements

Incoterms are international rules that help define responsibilities between buyer and seller in an international sale of goods. They establish issues such as delivery, transport, risk, insurance, costs and procedures related to the goods.

Although they are very useful, they do not replace the contract. A poorly chosen Incoterm can create disputes over who assumes a delay, damage during transport, unexpected costs or a customs incident.

In international distribution agreements, it is also important to regulate clearly:

• Territory granted to the distributor.
• Exclusivity or non-exclusivity.
• Minimum sales targets.
• Duration of the agreement.
• Termination conditions.
• Use of the trademark.
• Responsibility for local advertising.
• Governing law.
• Jurisdiction or arbitration.
• Post-contractual obligations.

For lawyers, the challenge is to anticipate conflicts before they arise. A well-drafted international contract must take into account legal, cultural, logistical and commercial differences between markets.

Tariffs and trade war: legal impact on global supply chains

Tariffs and trade tensions can deeply affect global supply chains. A cost increase, an import restriction or a change in customs classification can affect the final price, profit margin and viability of a transaction.

From a legal perspective, companies must review:

• Tariff classification of products.
• Country of origin of the goods.
• Applicable trade agreements.
• Rules of origin.
• Customs documentation.
• Price adjustment clauses.
• Allocation of unexpected costs.
• Risks caused by delays or blocks.
• Alternative supply options.

Trade wars do not only affect large multinationals. They can also impact exporting SMEs, distributors, manufacturers, logistics operators and companies that depend on international suppliers.

A lawyer specialized in international trade helps reduce these risks, review contracts, adapt supply chains and design customs compliance strategies.

How to negotiate an international contract: key clauses and dispute resolution

Negotiating an international contract requires attention to issues that may be less complex in a domestic agreement. When parties are located in different countries, any dispute can become more complicated due to legal differences, language, currency, jurisdiction, procedural costs or enforcement of decisions.

Some especially important clauses are:

• Governing law.
• Jurisdiction or arbitration.
• Contract language.
• Payment currency.
• Delivery terms and deadlines.
• Applicable Incoterm.
• Force majeure.
• Limitation of liability.
• Confidentiality.
• Intellectual property.
• Regulatory compliance.
• International sanctions.
• Termination mechanisms.

In many transactions, international arbitration can be a useful way to resolve disputes in a more specialized and neutral manner. In this regard, the Master in Business Law, Arbitration and ADR can complement the profile of those who want to work in international contracts, negotiation and commercial dispute resolution.

Economic security and foreign investment screening

Economic security has become a growing concern for many States. Certain foreign investments may be reviewed or even blocked when they affect strategic sectors, critical infrastructure, sensitive technology, defence, energy, telecommunications, data or essential resources.

This means that an international corporate transaction should not only be analysed from a commercial or financial perspective. It may also require prior regulatory review to determine whether administrative authorization is needed.

This type of control may affect:

• Acquisition of companies.
• Purchase of significant shareholdings.
• Investments in strategic sectors.
• Transactions involving foreign investors.
• Entry of international funds.
• Transfer of sensitive technology.
• Control over critical infrastructure.

For companies, anticipating these requirements is essential. An unexpected authorization requirement can delay a transaction, change its conditions or even prevent its completion.

A key specialization for companies operating in global markets

International trade offers major opportunities, but it also requires legal certainty. Companies need to know who they are dealing with, which rules apply, how goods are transported, what customs risks exist and what happens if a dispute arises.

In an environment marked by trade tensions, new restrictions, complex supply chains and greater control over strategic investments, the role of the lawyer specialized in international trade is increasingly relevant.

Specializing in this area means preparing to advise on transactions where law, business, geopolitics, logistics and regulation constantly intersect.
