Dropshipping Fashion Landed Cost in Singapore: From Supplier to Shelf

Which Cost Measure Answers Which Question

These measures answer different operating questions. Supplier price is the amount quoted by the supplier for the item before the other costs of getting it into Singapore. Use it to compare product quotes or negotiate sourcing; it is not enough to set a selling price. Landed unit cost assigns the relevant import costs to one sellable unit. Use it to test whether the product economics work before advertising or scaling.

Cash paid at import is a cash-flow measure: the amount actually paid at checkout, to the carrier or to customs for that shipment, including any GST charged at that point. Singapore’s current GST rate is 9%, according to the Inland Revenue Authority of Singapore. Cash paid can exceed accounting cost when GST is recoverable, so do not automatically use it as product cost. Product margin is selling revenue less landed unit cost, before store overhead and advertising. For pricing decisions, use the margin in dollars and as a percentage of selling revenue. A product pricing calculator can keep these inputs separate (Source: Inland Revenue Authority of Singapore).

What Landed Cost Includes

Landed unit cost is the cost of one fashion item from the supplier invoice through its arrival in Singapore. It measures what it takes to bring the product into the market, not what it costs to acquire or convert a customer. Keep each component visible rather than combining every charge into one supplier-cost number:

Use the measure when setting a viable product price, comparing suppliers, or checking whether a product remains profitable after import costs. Fulfilment, payment processing, advertising, discounts and refunds are outside landed cost. They belong in separate contribution or net-profit measures so you can see whether an issue comes from importing the item or selling it.

Tax treatment needs care. The Inland Revenue Authority of Singapore states that the current GST rate in Singapore is 9%. For low-value goods, sales value of S$400 or below imported by air or post, a GST-registered overseas supplier charges GST at the point of purchase. Record GST according to your business’s actual treatment; do not silently fold it into product cost when it is tracked separately (Source: Inland Revenue Authority of Singapore).

Duty and Classification Basics

Product classification is the starting point for determining how Singapore customs treats a fashion import. The relevant classification depends on what the item is and how it is made, not simply the supplier’s product title or your store’s collection name. That classification can affect whether duty treatment applies and how the import taxes are assessed, so a dress, scarf and pair of trousers should not be grouped under one generic “apparel” description.

Your declared description should match the product’s official documentation. Record the garment type, material composition and construction accurately, such as “women’s knitted cotton T-shirt” or “polyester woven blouse,” rather than “fashion top.” The same facts should appear consistently across the supplier invoice, packing details and customs information. If a listing says cotton but the invoice says polyester, or a knitted item is documented as woven, the inconsistency can lead to classification questions and a cost model built on the wrong treatment.

For each SKU, retain the supplier’s material and garment specifications before calculating dropshipping fashion landed cost in Singapore. Treat marketing copy as a sales description, not as evidence for customs classification. If the product cannot be described precisely, pause the calculation and obtain corrected documentation; an apparently low supplier cost is not useful if the import assumptions do not match the goods actually shipped.

Allocating Freight to Units

Allocate shipment-level freight using a measurable driver, rather than spreading it evenly without explanation. Chargeable weight is appropriate when the carrier bills on actual or volumetric weight. Volume can be more representative for bulky garments, while item count is practical when products are similar in size and handling requirements.

For illustration only, assume S$120 freight for 35 units. The shipment contains 20 T-shirts, 10 dresses and 5 jackets. The table shows each method’s result before rounding. Under chargeable weight, a dress receives S$4.50 of freight per unit because 15 kg ÷ 40 kg × S$120 ÷ 10 units. Under item count, every unit receives S$3.43, regardless of size.

Rules to confirm before importing to Singapore

Before importing a fashion item, record the assumptions that determine its Singapore cost: supplier invoice price, currency, shipping terms, transport charge, insurance if applicable, product description, and the party responsible for each charge. Keep the supplier quotation, commercial invoice and tracking or freight documents together. If the supplier changes the material, construction or packaging, review the classification and cost model rather than carrying forward the old assumption.

Confirm the GST treatment before setting a selling price. Singapore’s current GST rate is 9%, according to the Inland Revenue Authority of Singapore (IRAS). A Singapore business must register for GST when its taxable turnover for a calendar year exceeds $1 million, or when it expects taxable turnover of more than $1 million in the next 12 months. That status affects whether GST is treated as a recoverable tax or as part of the store’s economic cost, so do not mix the two cases in one product model (Source: Inland Revenue Authority of Singapore).

Check whether the order falls under Singapore’s low-value goods rules. 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, according to IRAS. Confirm the supplier’s registration status, the sales value used for the transaction, and whether GST appears separately on the checkout or invoice.

Use this pre-import check before publishing a product price:

• Match the item description and materials across the supplier quote, invoice and product listing.
• Confirm who collects GST and whether the quoted price includes it.
• Record the currency and convert costs consistently into Singapore dollars.
• Model the product using the expected customer outcome: delivered, cancelled or returned orders should not be treated as equivalent sales.
• Recalculate the unit economics when the supplier, shipping route, packaging or GST treatment changes.
