What Is International Trade?

International trade refers to the exchange of goods and services across national borders. It generally occurs in two forms:

• Importing - purchasing products or services from overseas suppliers and bringing them into a domestic market.
• Exporting - selling products produced domestically to customers in foreign markets.

Why International Trade Matters

International trade allows businesses to:

• Access larger customer markets
• Reduce production and sourcing costs
• Diversify supply chains
• Improve competitiveness
• Increase revenue opportunities
• Gain access to specialized products and technologies

How International Trade Works

International trade involves three simultaneous flows:

1. Physical Flow - Movement of goods.
   Supplier → Carrier → Customs → Importer
2. Financial Flow - Movement of money.
   Buyer → Bank → Seller
3. Information Flow - Movement of documents.
   Contracts → Invoices → Shipping Documents → Customs Documents

The Typical International Trade Process:

1. Market Research - Identify product demand, target countries, and competitor pricing.
2. Source Suppliers or Buyers - Evaluate pricing and communication responsiveness.
3. Negotiate Commercial Terms - product specifications, payment terms, Incoterms.
4. Execute Trade Agreement - Prepare Purchase Order, Sales Contract.
5. Arrange Payment - Choose methods balancing trust and protection.
6. Shipping and Logistics - arrange appropriate shipping methods.
7. Customs Clearance - Complete import/export declaration, duty payments.
8. Delivery and Receipt - Receive cargo and verify quantity and quality.

Finding Reliable Buyers and Suppliers

Common Supplier Verification Steps

1. Request business registration
2. Conduct audits
3. Verify export history
4. Request samples
5. Start with pilot orders

Whether you are sourcing a supplier or finding a buyer overseas, due diligence is essential. Common sources for verified trade partners include:

• Government export promotion agencies
• Industry trade associations
• B2B platforms - in Exporters.SG, businesses are independently verified using our Trust systems.
• Trade fairs - in-person events remain one of the most reliable ways to meet verified buyers or suppliers.

Incoterms: who pays, who insures, who controls the goods

Incoterms are standardised trade terms published by the International Chamber of Commerce (ICC) that define the responsibilities of buyers and sellers in international transactions. They define exactly where the seller's cost and risk obligations end and the buyer's begin.

Most Commonly Used Incoterms

• FOB (Free On Board) - The seller delivers goods on board the named vessel. Risk passes to the buyer once goods are on board. The buyer arranges and pays for freight and insurance from the port of loading onwards.
• CIF (Cost, Insurance and Freight) - The seller pays freight and insurance to the named port of destination, but risk transfers to the buyer as soon as goods are loaded on the vessel.
• EXW (Ex Works) - Maximum responsibility for the buyer. The seller makes goods available at their premises; the buyer bears all costs and risks from that point, including export clearance.
• DDP (Delivered Duty Paid) - Maximum responsibility for the seller. The seller delivers goods cleared for import, with all duties and taxes paid. Widely used in e-commerce cross-border shipments.

In Exporters.SG, most importers preferred CIF and FOB (over 80% combined) for better cost and logistic control. Exporters chose FOB (over 70%) due to bulk cargo. See our guide on Commonly Used Shipping Terms for Exporters and Importers - What are they and How to choose.

International payment methods: how to get paid (and pay) safely

These are the common methods with different risk for buyer and seller:

1. Advance Payment - Buyer pays before shipment with high buyer risk. Maximum exporter protection
2. Open Account - Seller delivered goods before payment with high seller risk. Maximum importer protection
3. Documentary Collection - The seller's bank sends shipping documents to the buyer's bank with instructions to release them only when certain conditions are met.
4. Letter of Credit (LC) - A bank commitment to pay subject to compliant documentation.
5. Bank Telegraphic Transfer (TT) - Fast and widely adopted.
6. Escrow - Funds held by neutral party.

See our guide on B2B International Payment Methods: Types, Comparisons, and How to Choose.

Freight and logistics: moving goods across borders

Logistics determines delivery performance and total landed cost.

• Sea Freight - cheaper and best for bulk cargo but longer transit.
• Air Freight - faster delivery, ideal for urgent cargo and high-value goods but more costly.
• Rail/Road Freight - Offers a middle ground between sea and air: faster than sea, cheaper than air, for intercontinental or long-overland routes.

Customs Clearance and Trade Compliance

How customs clearance works:

1. Goods arrive at port of entry
2. Importer or customs broker lodges an import declaration
3. Customs authority assesses the declaration
4. Duties and taxes are calculated and paid
5. Goods are released for delivery

HS codes

The Harmonised System (HS) is an internationally standardised nomenclature for classifying traded goods. Every traded product is assigned a numeric code. The HS code determines the applicable import duty rate, licensing requirements, preferential tariff eligibility, and statistical reporting.

Misclassification can trigger back-payment of underpaid duties, interest, and penalties.

Managing Risk in International Trade

These are the common risks in international trade:

• Payment - Non-payment or delayed payment
• Fraud  - Fake buyers, suppliers, or documents
• Logistics - Shipment delays, theft, or damage
• Compliance - Regulatory penalties and shipment seizures
• Political - Trade restrictions, sanctions, or instability
• Currency - Exchange rate fluctuations affecting profitability

Understanding these risks before expanding into global markets are important. See our guide on Safe Trading for International Trade.

Market entry strategies for exporters

Deciding how to enter a new export market is as important as deciding which market to enter. The right mode of entry depends on your product, your resources, the market's size and complexity, and how much control you want to retain over your brand and customer relationships.

The main modes of export market entry:

• Direct exporting - Sell directly to overseas buyers.
• Distributor - Buys and resells your product.
• Agent / sales rep - Finds buyers on your behalf; you sell direct and pay commission.
• Joint venture - Partner with a local company and share investment, risk, and profit.
• Licensing / franchise - License a local entity to produce or sell under your brand.
• E-commerce / marketplaces - e.g. selling your products in Exporters.SG

Identifying target markets

Evaluate potential profitable markets based on:

• Market size and growth: Total addressable market (TAM), import volume for your HS code, market growth rate
• Competition: Who are the incumbent suppliers? What market share do they hold? What are their prices?
• Tariff and regulatory environment: Import duty rate, FTA eligibility, product certification requirements
• Logistics cost and complexity: Freight cost, transit time, port infrastructure, customs clearance efficiency
• Payment and credit risk: Currency stability, banking system reliability, typical buyer payment behaviour.

Adapting product for export markets

Product adaptation for an export market:

• Language: Labels, manuals, and packaging in the local language.
• Technical standards: Voltage and plug types (electrical products), measurement systems (metric vs. imperial), safety certifications (CE for EU, FCC for US, CCC for China).
• Regulatory compliance: Food labelling, pharmaceutical registration, toy safety standards, environmental standards.
• Cultural preferences: Colours, sizes, flavours, packaging styles with localization.

Pricing your product for export

Export pricing must account for:

• Your cost
• Export-specific costs (freight, insurance, documentation, additional packaging)
• Incoterm used
• Import duty and local taxes
• Currency risk

Exporters.SG offers a Market Research Tool to help you find prices, demand and understand market competition.

Sourcing and vetting suppliers

How to find and evaluate overseas suppliers

• Online B2B marketplaces: e.g. Exporters.SG. See our buyer guide.
• Trade exhibitions
• Industry associations
• Referrals
• Government trade offices

It is important that you verify sellers before committing to a transaction, arrange for safe shipping and payment method. See our Safety Tips for Buyers.
