Exporting goods and services can be a game-changer for Sri Lankan SMEs, but the journey from your factory or warehouse to a customer abroad isn’t as simple as shipping a package. In reality, when your business sends tea, apparel, or ICT services overseas, the destination government treats them as imports subject to duties, taxes, and tariffs that can significantly affect profitability. 

Moreover, beyond straightforward international shipping fees, these “invisible” costs, including customs duties and local taxes like VAT, are often applied before your goods ever reach the end buyer, making it essential for SMEs to understand the full landscape of import charges.

Defining the terms: Duties vs. tariffs vs. import taxes

In international trade, import duties, tariffs, and import taxes each play distinct roles in how a destination country assesses charges on goods entering, and understanding the differences helps you plan pricing and compliance more effectively.

Import duties

Import duties, often called customs duties, are standard charges imposed by a country’s customs authority on goods entering its borders. 

These duties are calculated based on the item’s classification under the internationally recognized Harmonized System (HS) Code, its declared value, and its origin, and are typically collected at the point of entry before your shipment can be released. Standard duty calculations often use the CIF value: cost, insurance, and freight as the taxable base.

Tariffs

While the term “tariff” is sometimes used interchangeably with duties, tariffs are more specific and policy-driven. A tariff is a tax that governments impose on particular imported goods, such as textiles, steel, or agricultural products, to protect local industries, manage trade balances, or retaliate in trade disputes. Tariff rates and affected products can change depending on trade agreements or economic goals.

Import taxes and local consumption levies

In addition to duties and tariffs, many countries levy broader import taxes, including consumption-based charges such as Value Added Tax (VAT) or Goods and Services Tax (GST). Unlike duties, these taxes are not specific to imports; similar taxes often apply to domestically produced goods as well, so importers pay both customs charges and domestic consumption taxes at customs clearance.

How do import charges impact your business margins?

Import charges such as duties, VAT, and levies don’t just show up on paper; they directly shape your product’s landed cost, which is the total amount you pay before goods reach the buyer. 

In Sri Lanka, customs duties can range from about 10% to 15% on many imports, with VAT at 15%,¹ plus other levies such as port and airport development charges, all of which must be factored into pricing to protect your margins and avoid unexpected losses.

Moreover, avoidable delays at customs are a major cost driver. When paperwork is incorrect or incomplete, shipments can sit at ports for days or weeks, adding demurrage and handling fees that eat into SMEs’ profits and slow delivery timelines. 

Identifying your shipment’s tax liability

Before you export or import, it’s critical to know what drives your shipment’s tax liability. These key factors help you estimate duties and taxes accurately, and position your business to optimize pricing and compliance.

• The HS code: Each product you ship is classified under a standardized Harmonized System (HS) Code, typically an 8-digit number, that tells customs exactly what your goods are. Your duty rate in Sri Lanka is based on this classification, which you can find in the Import Tariff Guide or obtain via an advance ruling.
• The de minimis threshold: Unlike some countries, Sri Lanka does not provide a de minimis threshold for business imports.² Most commercial shipments are taxed regardless of value.
• Customs value (CIF): Duties and taxes are calculated on the CIF value, which includes your product price plus shipping and insurance costs.
• Country of Origin: Duty rates often depend on where the goods were manufactured, not just where they’re shipped from, under origin rules in trade agreements.
• Destination tariff rates: The destination country determines the duty charged, and those rates can vary significantly depending on the product and the trade policies in place. For example, if the United States announces a 20% tariff on Sri Lankan exports,³ that rate applies when those goods enter the U.S. market. 
• Free Trade Agreements (FTAs): Sri Lanka has FTAs with India, Pakistan, and Singapore that can lower or eliminate duties for eligible goods, a major advantage if you comply with the rules of origin.

Who is responsible for paying: DDP vs. DDU?

When Sri Lankan businesses choose how to ship internationally, selecting the right Incoterm can make or break customer satisfaction and profitability. Two common options are Delivered Duty Paid (DDP) and Delivered Duty Unpaid (DDU); the key difference is who pays import duties and taxes upon arrival. 

Under DDP, the seller (your business) takes on full responsibility: you pay import duties, taxes, and handling fees in the destination country, so customers receive their orders with no surprise bills, which is especially valuable in B2C e-commerce, where unexpected costs can lead to abandoned carts or complaints.

Conversely, DDU places the responsibility on the buyer to settle those charges before customs will release the goods. If customers aren’t clearly informed upfront, this often leads to refused packages, returns, and negative reviews, undermining trust and future sales.⁴

Essential checklist for Sri Lankan SMEs

SMEs in Sri Lanka should follow a checklist to reduce costly delays, avoid compliance issues, and ensure smooth customs handling from origin to destination.

Prepare the right digital documentation

Accurate documentation is critical to clearing customs quickly and avoiding surprises. 

When exporting from Sri Lanka, your Commercial Invoice must include essential details such as your receiver’s email and phone number, as many customs authorities now require them for digital pre-clearance and processing. 

In addition, clearly stating the “Reason for Export” (for example, “E-commerce Sale” or “Business Export”) helps customs officials apply the correct B2C tax and regulatory rules in the destination country. Missing or vague details can lead to hold-ups, additional customs queries, and unexpected fees, which can disrupt your delivery timelines and customer experience.

Check for commodity-specific cesses

In addition to customs duties and tariffs, different products may be subject to levies or cesses depending on their HS Code. For example, exports of team one of Sri Lanka’s top foreign exchange earners, require registration with the Sri Lanka Tea Board Export Division and adherence to specific quality and export registration requirements.⁵

Exporters must also factor in the Tea Board Cess of Rs. 4 per kg⁶ when calculating their international pricing. Since this cess is charged per kilogram exported, it directly affects your landed cost and overall profit margin, making it essential to include it in your pricing strategy from the outset.
