What are the specific customs duties for the goods I plan to import or export?

Customs duties for your import/export company are determined by the Harmonized System (HS) code classification of your goods and applied to the CIF value (cost, insurance, and freight).

Each product you trade is assigned a specific 6 to 10-digit HS code that determines the duty rate in the destination country. Duty rates vary widely—from 0% for certain raw materials and machinery under free trade agreements to over 40% for strategic goods subject to protective tariffs. For example, U.S. steel and aluminum face additional tariffs, while India has implemented import surcharges on specific categories.

Three types of duty calculations exist: ad valorem rates (a percentage of the goods' value), specific duties (a fixed amount per unit, such as $5 per kilogram), and compound rates (a combination of both). You can search public tariff databases by HS code for each target market to find exact rates. Many import/export companies discover that products qualifying under FTAs enjoy reduced or zero rates, particularly for raw materials, machinery, and certain health or pharmaceutical products.

Which country of origin rules apply, and how do they affect my duty rates?

Country of origin rules determine which duty rate applies to your shipments, particularly when free trade agreements are involved.

Goods must be either "wholly obtained" in the origin country (such as agricultural products grown there) or "substantially transformed" (meaning significant manufacturing or processing occurred there). The correct country of origin must be supported by proof of origin documentation, which has replaced traditional certificates in many jurisdictions. For your import/export company, incorrectly declaring the origin can result in surcharges or anti-transshipment penalties reaching up to 40%.

Under FTAs like USMCA, ATIGA, or EFTA, origin rules become stricter. Each agreement defines specific criteria—such as minimum local content percentages or required production steps—that your goods must meet to qualify for preferential rates. If your supplier sources components from multiple countries, the final assembly location and value-added percentage determine the origin. Recent enforcement actions have targeted transshipment schemes where goods are routed through third countries to falsely claim preferential origin.

For import/export businesses, maintaining accurate supplier documentation and understanding transformation requirements is essential to avoid penalties and secure lower duty rates.

Are there preferential trade agreements or exemptions that can reduce my customs costs?

Preferential trade agreements can significantly reduce or eliminate customs duties for qualifying goods in your import/export operations.

Regional and bilateral agreements such as USMCA (United States-Mexico-Canada Agreement), ATIGA (ASEAN Trade in Goods Agreement), and EFTA (European Free Trade Association) offer lower or zero tariff rates for goods that meet specific origin and product requirements. Each agreement has unique documentation standards—some require digital certificates filed through official portals, while others accept supplier declarations. For your import/export company, understanding which agreements apply to your trade routes can reduce duty costs from 10-20% down to 0%.

Qualifying for FTA benefits requires thorough compliance with origin rules and timely submission of correct documentation. Many agreements also specify product exclusions or tariff-rate quotas that limit preferential access after certain volumes are reached. Some countries offer unilateral exemptions for development purposes, such as GSP (Generalized System of Preferences) programs that grant duty-free access to exports from developing nations.

This is one of the strategies explained in our import/export company business plan.

What additional taxes must I pay at the border beyond customs duties?

Beyond customs duties, import/export companies must pay VAT or GST on imports, calculated on the duties-inclusive value of the goods.

VAT rates vary significantly by destination: Thailand charges 7%, EU countries typically charge 20% or higher, and some Asian markets apply 5%. The tax base includes the CIF value plus any customs duties already paid, meaning VAT is calculated on top of duties. For example, if your goods have a CIF value of $10,000 and face a 10% duty ($1,000), the VAT is calculated on $11,000, not the original $10,000.

Excise taxes apply to specific categories such as alcohol, tobacco, luxury goods, vehicles, and certain cosmetics. These taxes are separate from VAT and often calculated per unit or as a percentage of value. Some countries also impose environmental taxes on goods like plastics or electronics with disposal concerns. For your import/export company, understanding the full tax burden—not just duties—is critical for accurate pricing and margin calculations.

What are the current customs clearance fees charged by authorities?

Customs clearance fees range from $25 to $100 per declaration depending on the complexity and jurisdiction.

How are customs valuation methods applied, and what costs must I include?

Customs valuation for import/export companies is primarily based on the transaction value method, which uses the price paid plus transport and insurance costs to the border (CIF value).

The transaction value is the foundation for calculating duties and taxes. You must add specific costs to the invoice price: commissions paid to agents, brokerage fees incurred as a condition of sale, packing costs, royalties and license fees required for the sale, and the cost of materials or tools supplied by the buyer. Transport and insurance costs up to the destination border must also be included. For your import/export business, failing to include these additions can result in undervaluation penalties.

Alternative valuation methods apply when the transaction value cannot be determined—such as for related-party transfers, goods without a clear sale price, or transfer-priced transactions. These alternatives include the transaction value of identical or similar goods, the deductive value method (based on resale price minus certain costs), and the computed value method (based on production costs plus profit). Certain costs can be deducted: post-import transport within the destination country, domestic handling and storage after import, and insurance beyond the border point.

We cover this exact topic in the import/export company business plan.

What documentation is mandatory to avoid penalties, delays, or additional costs?

Mandatory documentation for import/export companies includes commercial invoices with HS codes, packing lists, transport documents, digital customs declarations, and proof of origin.

• Commercial Invoice: Must include detailed HS code classifications (6 to 10 digits depending on the country), complete product descriptions, unit prices, quantities, terms of sale (Incoterms), and total shipment value. Inaccurate or missing HS codes are a leading cause of clearance delays.
• Packing List: Details the contents of each package, including dimensions, weight, and packaging type. Required for cargo handling and customs inspection purposes.
• Transport Documents: Bill of Lading (BL) for ocean freight or Air Waybill (AWB) for air cargo serve as proof of shipment and title documents.
• Digital Customs Declarations: Most countries now require electronic submissions through official portals (Thailand, EU, US all mandate digital-only filings with no physical paperwork). Your import/export company must register for portal access and submit declarations before goods arrive.
• Proof of Origin: Certificates or supplier declarations proving country of origin, particularly important for claiming FTA benefits. Digital origin certificates are increasingly replacing paper versions.
• Import/Export Licenses: Required for restricted goods such as pharmaceuticals, chemicals, agricultural products, electronics, or strategic materials. Specific licenses vary by product and country.
• Inspection Certificates: FDA approvals for food and drugs entering the US, phytosanitary certificates for plants and agricultural goods, health certificates for animal products, and conformity certificates for electronics or machinery in certain markets.

Are there inspection or certification fees required for the goods I plan to trade?

Inspection and certification fees for import/export operations vary by product category and range from $10 to $50+ per inspection, with some specialized categories charged as a percentage of shipment value.

Food products typically require health and safety inspections costing $20 to $50, while pharmaceutical goods face more rigorous testing with fees that can reach several hundred dollars depending on the destination country's regulatory requirements. Electronics and electrical goods often need conformity or safety certifications (such as CE marking in Europe or FCC approval in the US), with inspection fees averaging $30 to $75 per batch. Agricultural products require phytosanitary inspections to verify pest-free status, usually costing $15 to $40 per consignment.

Environmental or compliance checks add further charges for goods like chemicals, plastics, or items subject to REACH regulations in Europe. Some countries charge inspection fees as a percentage—pharmaceutical imports in certain Asian markets can incur fees of 0.5% to 1% of shipment value. For your import/export company, understanding which certifications and inspections apply to your product categories is essential for accurate cost forecasting and avoiding clearance delays.

What are the typical brokerage or agent fees for handling import/export formalities?

Brokerage and customs agent fees for import/export companies typically range from $30 to $100 per shipment as a flat fee, or 0.1% to 1% of the shipment value as a percentage-based charge.

Standard shipments with straightforward declarations usually incur flat fees at the lower end of the range ($30 to $50), while complex shipments involving multiple product lines, split deliveries, or goods requiring special permits face higher charges ($75 to $100+). Percentage-based fees are more common for high-value shipments, with rates varying by market standards—US customs brokers often charge 0.5% to 1% for shipments over $10,000, while European brokers may apply 0.1% to 0.3% depending on complexity.

Additional services increase costs: document preparation fees ($10 to $25), amendments to declarations after submission ($15 to $40), duty drawback or refund filings ($50 to $150), and consulting on tariff classification or valuation issues (hourly rates of $75 to $200). For your import/export business, choosing between in-house customs expertise and outsourcing to brokers depends on shipment volume, complexity, and the learning curve for each market's requirements.

What storage or demurrage charges may apply if goods are held at customs?

Storage and demurrage charges for delayed customs clearance range from $20 to $100+ per day per container, depending on the port, warehouse type, and grace period.

Are there penalties or surcharges for late payments, incorrect declarations, or missing documents?

Penalties and surcharges for errors in import/export operations can reach up to 40% of the shipment value for serious violations like transshipment fraud or deliberate misdeclaration.

Late payment of duties triggers interest charges and administrative penalties—most countries charge 1% to 2% interest per month on overdue duties, plus fixed late-payment penalties ranging from $50 to $500 depending on the amount owed and delay duration. Incorrect declarations result in assessment penalties: undervaluation by 10% or more can incur surcharges of 10% to 25% of the underpaid duty amount, while classification errors may lead to reclassification at higher duty rates plus administrative fines of $100 to $1,000.

Missing or incomplete documentation causes clearance delays and triggers document deficiency fees ($25 to $75 per missing document) plus accumulated storage charges during the delay period. More serious violations carry steeper penalties: false origin declarations to fraudulently claim FTA benefits can result in duty recovery at full non-preferential rates plus penalties up to 40% of the shipment value; transshipment schemes designed to evade anti-dumping duties or country-specific tariffs face similar surcharges; and repeated compliance failures can lead to increased inspection rates, loss of trusted trader status, or suspension of import/export privileges.

It's a key part of what we outline in the import/export company business plan.

What recent regulatory changes might impact my customs duties or related charges?

Recent regulatory changes in 2025 include mandatory digital customs declarations, increased clearance fees, elimination or reduction of duty-free thresholds, and new reciprocal tariff structures.

Digital-only customs declarations are now mandatory in Thailand, the EU, and the US—physical paperwork is no longer accepted, and all filings must be submitted through official electronic portals before goods arrive. This shift has increased compliance requirements for import/export companies, requiring portal registration, digital signature certificates, and often integration with customs software systems. Failure to file digitally or delays in electronic submission trigger automatic administrative fees and storage charges.

Customs user fees and brokerage permit fees have increased across multiple jurisdictions for 2025. The US Customs and Border Protection raised merchandise processing fees, while several EU member states adjusted clearance charges to reflect inflation and increased enforcement costs. Duty-free de minimis thresholds—the value below which imports enter duty-free—have been eliminated or significantly reduced in the US and Mexico, meaning low-value shipments that previously entered free now incur full duties and taxes.

New reciprocal tariff agreements and restructured preferential trade deals came into effect in 2025. Some countries imposed retaliatory tariffs on specific goods from trading partners, while others updated FTA rules of origin to require higher local content percentages. For your import/export company, staying current with these changes through regular consultation of official customs tariff databases and trade association bulletins is essential to avoid unexpected costs and compliance violations.
