How to Calculate Landed Cost When Importing from Thailand
The invoice price from your Thai supplier is only the starting point. By the time a shipment clears customs and reaches your warehouse, freight, duty, insurance, taxes and handling
The invoice price from your Thai supplier is only the starting point. By the time a shipment clears customs and reaches your warehouse, freight, duty, insurance, taxes and handling fees can add a significant chunk on top of what you paid at origin — and if you quoted a retail price before knowing that number, your margin is the one that absorbs the surprise. Learning how to calculate landed cost properly, before you place an order, is what separates importers who price confidently from those who find out their real costs only after the goods arrive. This guide walks through the full formula, where buyers underestimate it, and how it changes depending on whether you're sourcing skincare, herbal products or general goods from a Thai wholesale distributor.
What landed cost actually includes
Landed cost is the total cost of getting a product from the supplier's factory floor to your own warehouse, ready to sell. At minimum, it covers: the product cost (FOB or EXW price negotiated with the supplier), inland freight in Thailand to the port or airport, international freight (sea or air), marine/cargo insurance, import duty, VAT or sales tax at destination, customs broker and clearance fees, and last-mile delivery to your warehouse. Some importers also add a line for bank charges on international transfers and for any inspection or testing fees required for the product category. Missing even one of these line items is the most common reason a landed cost estimate turns out lower than reality once the shipment actually clears.
The basic landed cost formula
A simple working formula is: Landed Cost = Product Cost + Shipping + Insurance + Duties & Taxes + Handling/Broker Fees. For a per-unit figure, divide the total by the number of units in the shipment. The tricky part is that duty and tax are usually calculated on CIF value (Cost + Insurance + Freight), not on the product cost alone — so you need freight and insurance figures before you can estimate duty, not after. Import duty rates and VAT vary by product classification (HS code) and destination country, so this isn't a fixed percentage you can reuse across categories; it's worth checking the applicable rate with your customs broker or your country's customs authority for each new product line rather than assuming last year's rate still applies.
Why the calculation differs by product category
Landed cost isn't just about freight mode — the product category changes what else gets added to the formula. If you're importing from a Thai skincare wholesale supplier, cosmetic products may need to meet labeling and ingredient documentation requirements at destination, and your customs broker may ask for supporting paperwork before releasing the shipment, which can add time and sometimes a line-item cost for document preparation. Thai herbal products can fall under stricter review depending on whether they're classified as cosmetics, supplements or food products in your destination market — this classification affects both the duty rate and whether additional certificates are requested at the border. It's always worth confirming the exact requirements with your destination customs authority or an experienced broker before finalizing your landed cost estimate, since assumptions here are where budgets go wrong.
Freight mode: the biggest lever in your landed cost
Air freight is faster but priced by weight and volume, which makes it expensive for bulky, low-value goods and more reasonable for light, high-value items like skincare or supplements. Sea freight (FCL or LCL) is slower but usually brings the per-unit freight cost down significantly once volumes grow, which is why many importers start with air freight for test orders and switch to sea freight once order sizes justify it. When comparing freight quotes, ask for an all-in quote that separates freight, insurance, and destination handling charges — bundled 'door-to-door' quotes can hide which component is driving the cost, making it harder to spot where you can negotiate or switch providers.
Building a landed cost worksheet before you order
Before confirming any purchase order, build a simple worksheet with rows for product cost, Thailand-side logistics, international freight, insurance, destination duty, destination tax, broker fees and last-mile delivery — then fill in real quotes rather than estimates wherever possible. This is also the point where it pays to compare more than one supplier and more than one freight quote, since both product pricing and shipping costs can vary meaningfully between vendors for what looks like the same item. Many importers use this stage to request quotes from Thai suppliers side by side, which also surfaces differences in packaging, minimum order sizes and payment terms that affect the total cost beyond the unit price alone.
Working with the right partners to keep the numbers accurate
Landed cost calculations are only as reliable as the quotes feeding into them. Sourcing from verified Thai suppliers reduces the risk of inconsistent pricing, unclear Incoterms or last-minute cost additions that throw off your worksheet after you've already committed to an order. If you're new to a category — say, moving from general goods into a Thai skincare wholesale line or adding Thai herbal products to your catalogue — it's worth working with a Thai wholesale distributor or sourcing agent who can confirm product-specific duty classifications and documentation needs upfront, rather than discovering them at customs. Platforms in the Thailand sourcing space, such as ThaiNex or THAIMOST, are sometimes used by importers to compare supplier quotes and freight options in one place before committing to a landed cost estimate.

FAQ
Frequently asked questions
Is landed cost the same as FOB price plus shipping?
No. FOB price plus shipping gets you close, but it typically leaves out insurance, destination duty and tax, customs broker fees, and last-mile delivery — all of which are part of a complete landed cost calculation.
How do I find the correct duty rate for my product?
Duty rates depend on the product's HS code and your destination country's tariff schedule. Check with your destination customs authority or a licensed customs broker, since rates and exemptions can change and vary by product classification.
Does landed cost change between air and sea freight?
Yes, significantly. Air freight raises the shipping line item but shortens lead time; sea freight usually lowers per-unit freight cost at higher volumes but takes longer, which affects cash flow and inventory planning as well as the final number.
Should I calculate landed cost before or after getting supplier quotes?
After. You need real product cost and freight quotes to calculate duty and tax accurately, since both are typically based on the CIF value rather than the product cost alone. This is why many importers request quotes from Thai suppliers before finalizing their cost worksheet.
