When tariffs change, landed cost updates should follow a routine: verify the official rate and scope, identify affected SKUs and open orders, recalculate unit costs with stacking rules, then decide pricing, sourcing, and customer communication in that order. A written routine prevents the two common failures: repricing on headlines and forgetting in transit stock.
Verify, then scope
Start from the official text, never the headline: exact classifications covered, new rate, stacking with existing measures, effective date, and in transit treatment. Then scope the exposure: which SKUs classify in the affected lines, what inventory and open purchase orders sit in each, and which customer commitments were priced on the old rate.
For more on this, see this related guide and our earlier explainer on the same theme.
This scoping step is where money hides. A change covering one subheading can touch a handful of SKUs or half the catalog depending on classification quality. Companies with clean classification data scope in hours; companies without it spend the week arguing about which products are even affected.
Recalculating unit costs properly
Rebuild landed cost per affected SKU: product cost, freight, insurance, base duty, additional measures in their correct stacking order, and fees that vary with value. Watch for knock on effects: higher dutiable value interactions, bond sufficiency as duty totals climb, and cash flow timing, since duties are paid at entry long before the goods sell.
Model at least two scenarios where scope or dates are uncertain, and label every number with the verified facts it rests on. Decision makers can handle ranges honestly labeled; what damages trust is a single precise cost built on an unverified headline, presented as fact and quietly revised three times.
Pricing and communication decisions
With real costs in hand, decide deliberately among absorbing, passing through, splitting, or redesigning the offer, per product line rather than by blanket rule. Consider contract terms: some customer agreements fix prices for a period, some contain change clauses, and discovering which is which belongs in this step, not in a dispute later.

Communicate price changes with the verified facts, the effective date, and enough lead time for customers to plan. Businesses accept tariff driven changes they can verify; they resist changes that smell like opportunism. A short, factual notice tied to the official action preserves relationships that a vague market conditions letter spends.
Closing the loop at entry
Update broker instructions, system rate tables, and the tariff register the same week, then sample the first entries under the new rate to confirm application. Reconcile duty paid against the model monthly for the first quarter; variances point at classification or stacking errors while they are still cheap to correct.
File the whole episode: verification notes, scope list, models, decisions, notices. The next tariff change starts from this file instead of from memory, and the routine gets faster every cycle. In a volatile tariff environment, the speed of this loop is a genuine competitive advantage.
Frequently asked questions
What is the first step when a tariff change is announced?
Verify it in the official text: classifications covered, rate, stacking, effective date, and in transit rules. Then scope affected SKUs, inventory, and open orders. Repricing or communicating before verification is how companies act on headlines that turn out to cover different products.
How should stacking duties be calculated?
Apply each measure according to its own rules on the customs value, in the order the official notices specify, rather than compounding informally. Additional measures usually stack additively on value. Model per SKU and confirm against the first real entries after the effective date.
Should tariff increases be passed to customers in full?
It depends on the product line, contracts, and competition. Decide per line among absorbing, passing through, splitting, or redesigning the offer, using verified costs. Whatever the choice, communicate with the official facts and reasonable lead time; verifiable changes are accepted far better.
How do we make sure the new cost model matches reality?
Reconcile duty actually paid against the model monthly for the first quarter after a change, and sample entries for correct rates and stacking. Variances found early are cheap corrections; variances found at audit are expensive ones.
