From Supplier Price to Landed Unit Cost

Supplier invoice cost is the amount charged by the supplier for the gadgets themselves. It is useful for comparing product quotes and checking whether a supplier’s unit price has changed, but it does not tell you what each sellable unit costs after import. For illustration only, an invoice for 100 units at S$8 each shows an S$800 supplier cost.

Shipment cost is the total charged for moving that order to Singapore. Use it to compare shipping methods, freight quotes and order sizes. It remains a consignment-level figure, so it cannot be compared directly with a retail price or product margin until it is assigned across units.

Landed unit cost is the final cost per sellable unit after the supplier invoice, shipment cost and applicable import-related amounts have been assigned. If the S$800 order has S$200 shipment cost and S$100 in other applicable charges, the landed unit cost is (S$800 + S$200 + S$100) ÷ 100 = S$11. That is the figure to use when checking product economics, setting a price target or measuring gross profit. A product pricing calculator can help test the arithmetic. Keep the calculation in one currency; ORVX keeps each merchant’s trading currency without mixing currencies in one figure.

What Landed Cost Includes

For dropshipping gadgets landed cost in Singapore, include every cost required to bring the item to the point where it is available for sale. The calculation normally contains:

Goods: the supplier’s charge for the gadget. Freight: international shipping and any transport needed to reach Singapore. Insurance: cargo cover when purchased or required. Duty: any customs duty applicable to the product’s classification and origin. Import tax: Singapore import GST where applicable. Eligible fees: necessary customs-clearance, documentation, handling or delivery charges paid to release and receive the shipment. Allocate shared charges across the units they relate to rather than attaching the whole invoice to one product.

Keep landed cost separate from selling and operating costs. Customer delivery charged after checkout, payment-processing fees, Shopify subscriptions, advertising, salaries, storage for general operations and returns are not part of the product’s landed cost. They belong in contribution or net-profit analysis.

The current GST rate in Singapore is 9%, according to the Inland Revenue Authority of Singapore (IRAS). A GST-registered business may track import GST separately when it is recoverable; a business unable to recover it should assess whether it is part of its economic product cost. IRAS also defines low-value goods as goods with a sales value of S$400 or below imported by air or post, where a GST-registered overseas supplier charges GST at purchase (Source: Inland Revenue Authority of Singapore).

  • Use landed unit cost to set or test product economics.
  • Use total cash outlay to plan the payment needed for an order or shipment.

Worked example with sample numbers

This example is illustrative. It uses sample numbers for a dropshipping gadgets store selling in Singapore. They are made up to show the method, they are not a benchmark, and your own figures will differ.

Formula: Landed unit cost = (supplier cost + freight + duty + fees) / units.

Sample numbers: 320 units on one shipment, with a 7.2% duty rate chosen for illustration

DutyS$366.15S$1.14

Duty and Classification Basics

Customs treatment starts with the product’s actual characteristics, not a store title such as “trending gadget.” Record what it is, what it does, its materials, power source and intended use. A wireless charging stand, for example, may require different classification analysis from a phone case. Use the applicable HS classification only after checking product specifications and supporting customs documentation; do not estimate a code from a supplier marketplace listing.

Country of origin means where the product was made under the relevant origin rules, not simply the country from which the supplier dispatches it. It can affect whether preferential treatment is available, so retain an origin statement or other supporting evidence. The customs value is the value used for import assessment and may not equal the supplier’s product-line price. Keep the commercial invoice, payment record, freight documents and any valuation adjustments together so your calculation can be reconciled.

Separate customs duty analysis from GST and from your store’s profitability model. Singapore’s current GST rate is 9%, according to the Inland Revenue Authority of Singapore. Whether GST is charged at import or at the point of purchase can depend on the transaction and low-value-goods rules. For pricing decisions, compare the documented customs treatment with the product cost recorded in your model rather than applying an assumed duty rate (Source: Inland Revenue Authority of Singapore).

Allocating Freight to Units

Assign shipment-level freight, insurance and shared handling charges to units using a basis that reflects what drives the cost. If a charge relates to one SKU only, assign it directly. For a mixed shipment, separate the shipment total from product costs, then allocate the shared amount consistently.

Quantity is suitable when gadgets have similar carton sizes and handling requirements. Use weight when the carrier charges mainly by kilograms; use volume when bulky, lightweight products consume container or aircraft space. Do not use quantity for a shipment where one item weighs or occupies several times more space than another.

For illustration only, allocate S$150 of shared costs across 60 units of Gadget A and 40 units of Gadget B. The table shows how the result changes by method. Weight or volume is the more defensible basis when those measures drive the freight invoice; quantity is simpler when the units are operationally alike.

Example allocation of S$150 shared shipment costs
BasisGadget A allocation / unitGadget B allocation / unitUse when
QuantityS$1.50S$1.50Units are similar in size and handling
WeightS$1.07S$2.14Freight is driven by kilograms
VolumeS$0.94S$2.34Freight is driven by package space

Rules to Confirm Before Importing to Singapore

Before paying a supplier, verify the shipment route with Singapore Customs. Check whether the importer, courier or freight forwarder must obtain an import permit through TradeNet, and who is responsible for submitting it. Confirm the product description, declared value, importer details and supporting documents match the order. Singapore Customs guidance is the reference for permit and import documentation requirements.

Confirm the GST treatment with the Inland Revenue Authority of Singapore (IRAS). The current GST rate in Singapore is 9%, according to IRAS. Low-value goods are goods with a sales value of S$400 or below imported into Singapore by air or post; a GST-registered overseas supplier charges GST on them at the point of purchase. Do not assume this treatment applies to every order, especially if goods are consolidated or sold through different channels (Source: Inland Revenue Authority of Singapore).

Check product rules before listing the gadget. Singapore Customs, Enterprise Singapore, IMDA and other relevant regulators may apply requirements depending on whether the item is controlled, electrical, wireless, medical or battery-powered. Keep the commercial invoice, packing list, airway bill, product specifications, conformity documents and permits where applicable. Record the source and date of each check so your landed-cost model reflects the confirmed route.
