How tariffs affect clothing brands

Tariff exposure starts before a shipment reaches the warehouse. The garment’s tariff classification, country of origin and customs value determine the duty assessment. The supplier invoice is an important input, but it is not automatically the full customs basis: the declared value, shipment terms and other import costs can affect what enters the calculation. A classification or origin error can therefore create either an unexpected bill or a compliance issue.

Once paid, duty usually becomes part of the product’s landed cost alongside the supplier charge, freight, insurance, brokerage and other import costs, subject to the brand’s accounting treatment. That raises unit cost even when the factory invoice is unchanged. If the retail price stays fixed, gross profit and gross margin fall. If the brand raises price to protect margin, the higher ticket can affect conversion, units sold and customer acquisition economics; the effect is not known from the tariff rate alone.

The impact then spreads through inventory. Purchase orders may require more cash, existing stock may carry a different cost from incoming stock, and replenishment decisions can change when a product appears less profitable. Slower demand after a price change can leave excess units or dead stock, while delaying a purchase can create availability risk. Reliance on one supplier, origin country or classification also increases exposure to future cost or documentation changes.

Track the chain at the level where the decision occurs. ORVX reports product- and collection-level profitability, computes cost of goods from a product cost model, and reports inventory position, dead stock and remaining stock value. Its realized revenue uses delivered orders only, excluding cancelled and returned orders, so the margin view can be checked against actual sales rather than booked demand.

The formula, stated plainly

Start with the unit inputs. Customs value is the value used by customs to assess duty, usually the declared transaction value of the imported goods, not automatically the full amount paid to deliver them. Freight is the cost of transporting goods to the import point; insurance covers transit risk; brokerage is the customs broker’s clearance fee. Add port handling, inspection fees, domestic inbound freight, nonrecoverable import taxes and other shipment charges when they are part of getting inventory ready for sale.

For an ad valorem tariff, duty per unit is: (customs value per unit × duty rate) + any specific duty charged per unit. Landed unit cost is: product purchase cost + international freight + insurance + duty + brokerage + port and handling charges + domestic inbound freight + other nonrecoverable import costs. Allocate shipment-level charges across the units received using a consistent basis, such as unit count, weight or value.

For inventory sold, cost of goods sold (COGS) is landed unit cost × units sold. Gross margin is (realized revenue − COGS) ÷ realized revenue. Use realized revenue from delivered orders, excluding cancelled and returned orders, so the denominator matches the sale that produced the cost.

Contribution margin goes one step further: (realized revenue − COGS − variable selling costs) ÷ realized revenue. Variable selling costs can include payment fees, fulfillment, returns processing and advertising when those costs vary with sales. Tariff-driven cost change is new landed unit cost − old landed unit cost. At shipment level, multiply that change by units received; at product level, multiply it by units sold to measure the COGS effect.

• Act on gross margin when evaluating the product’s sourcing economics and whether its landed cost supports the current retail price.
• Act on contribution margin when deciding whether to keep acquiring customers or promoting the product, because advertising and other variable selling costs are included.

A worked example with real numbers

Consider a jacket sold for $120. Assume its customs value is $32 per unit, freight and insurance add $6, and the tariff scenario is 20% of customs value. The duty is therefore $32 × 20% = $6.40, lifting landed product cost from $38.00 to $44.40. This is an illustrative scenario; the applicable rate depends on the SKU’s classification, origin and customs treatment.

Assume fulfillment costs $8.00 per order, packaging costs $1.50, payment processing is 3% of selling price, and advertising costs $18 per delivered order. At 1,000 delivered orders per month, fixed operating overhead is $20,000. The comparison below holds price, volume and all non-tariff costs constant, so it isolates the tariff’s arithmetic rather than predicting customer demand.

Before the tariff, gross profit is $120 − $38 = $82 per unit, or 68.3%. After the tariff, it is $120 − $44.40 = $75.60, or 63.0%. Contribution after advertising falls from $50.90 to $44.50 per order. At 1,000 orders, monthly operating profit falls from $30,900 to $24,500 after the assumed overhead—a $6,400 reduction, exactly matching the additional $6.40 duty per unit.

Compare the decisions before changing price

Treat the tariff as a decision variable, not an automatic price increase. Compare the incremental duty with the contribution you protect, the demand you might lose, the cash tied up in inventory and the time required to change supply. A $4 duty on a $40 landed-cost product reduces gross profit by $4 per unit if price and volume stay unchanged. A $5 price increase restores more than that unit margin only if the product still sells at a commercially acceptable rate.

Absorbing the cost is usually a short-term demand and positioning choice. It can make sense for a proven traffic driver, a price-sensitive entry product or a launch where conversion data is more valuable than immediate margin. Raising price is more defensible when the product has differentiated demand, low return risk and enough gross profit to absorb a conversion decline. Do not treat a higher list price as a forecast of demand: ORVX can identify where a price experiment is worth running, but it cannot estimate price elasticity or predict the response.

Changing the mix protects cash when some styles have stronger contribution or less tariff exposure. Push replenishment and marketing toward those products, while discounting or slowing buys for weak economics—but check remaining stock value and dead stock first. Renegotiating supplier price, payment timing, minimums or freight terms can improve margin without changing the customer offer, although the benefit depends on supplier leverage and contract timing. Shifting sourcing is a structural option: it may reduce exposure, but adds qualification work, lead time, compliance risk and potentially higher sampling or setup costs. Delaying an order preserves cash and avoids committing to uncertain landed cost, but risks a stockout, missed season or lost sales.

• Use absorption when demand protection and brand price consistency matter more than near-term contribution.
• Use a price test when unit economics require recovery and the product has enough differentiation to justify learning.
• Use mix changes when existing products offer a faster margin improvement than new sourcing or supplier negotiations.
• Use renegotiation when the supplier relationship and order timing provide practical leverage.
• Use sourcing changes for persistent exposure, not for a one-off shipment that cannot support qualification time.
• Use order delays when cash or inventory risk is urgent and the cost of a stockout is lower than the cost of committing.

The mistakes that make tariff analysis wrong

The first error is applying the tariff rate to the retail price. A $100 dress is not necessarily assessed on its $100 selling price. If the customs value is $24, a 25% duty produces $6 of duty per unit, not $25. Retail price is useful for pricing and margin analysis; customs value is the relevant starting point for duty exposure.

Classification can change the result before any arithmetic begins. Garment type, fiber composition, construction and intended use can affect the HTS classification and applicable rate. Using a supplier’s generic label, or assuming two similar-looking products share a code, can make a sourcing comparison unreliable. Origin is a separate question: the country shipping the parcel is not always the country of origin, and a preferential treatment may require specific origin conditions.

Keep product value, freight, insurance and other import charges in separate fields. Mixing them into one landed-cost number can apply the rate to the wrong base or count the same cost twice. Do not assume every shipment qualifies for de minimis treatment either; eligibility depends on the shipment and applicable rules. Validate the treatment for each route rather than building a forecast on a blanket assumption. The US import cost guide provides useful context for separating these inputs.

A blended tariff average can also conceal the decision that matters. A 15% portfolio average may combine a 0% item with a 30% item, different origins and different unit costs. Model duty by SKU, classification, origin and shipment where possible. Finally, distinguish gross margin from profit: gross margin shows product economics after cost of goods, while net profit also reflects advertising, returns, fulfillment and overhead. Use duty-per-unit to evaluate sourcing, gross margin to evaluate product economics and net profit to decide whether the business can absorb the change.

What the current US rules change

The current US framework adds layers to the ordinary HTSUS duty rather than replacing classification. USTR Section 301 notices and CBP implementation guidance can add China-specific duties to covered goods. Federal Register and CBP notices for Section 232 and country-based measures can add further duties where the product and origin fall within their scope. Each layer applies at entry, so a sourcing change can alter exposure even when the product and selling price stay the same.

The commercial effect differs by category. Apparel often requires style-, fiber-, and construction-level HTSUS review, so a factory change does not by itself establish a new origin or rate. Electronics require checking whether the finished item, a component, or an exclusion is covered. Home and furniture imports require separate review of the exact article, materials, origin, and any trade-remedy notice. CBP’s current entry guidance also determines whether low-value shipments qualify for de minimis treatment; if they do not, eligible parcels move into formal duty and entry-cost workflows. Census trade data can show import values by commodity and country, but it does not determine a merchant’s tariff liability.

• Use the HTSUS for the base classification and rate; use USTR, Federal Register, and CBP notices for additional measures, exclusions, effective dates, and filing instructions.
• Act on a sourcing change only after confirming the product’s classification, substantial transformation, country of origin, and the rule in force on the entry date.
