Pass through is the share of a tariff cost increase that ends up in customer prices rather than absorbed in margin. It depends on competition intensity, how exposed rivals are to the same tariff, contract terms, customer price sensitivity, and whether the increase looks permanent. Recent broad tariffs saw high pass through in many categories because every competitor faced the same cost, making industry wide price moves safer than absorbing alone.
The determinants, in order of usual importance
Competitive exposure comes first: if the tariff hits the whole category, prices rise together and pass through is high; if it hits only you, raising price is donating share. Demand sensitivity follows: necessities with few substitutes accept increases that discretionary products with easy deferral cannot.

Permanence shapes the response too. Firms absorb temporary looking costs in margin and pass through costs they expect to keep, because repricing has its own costs in systems, contracts, and customer goodwill that nobody spends on a ninety day tariff. Credibility of the policy path is an input to the pricing decision.
Partial pass through is the normal case
Headlines frame absorb or pass as a binary; real responses split the cost three ways: some to price, some to margin, some to cost engineering like renegotiation, redesign, and sourcing shifts. The proportions move over time: margin absorbs the shock quarter, renegotiation lands next, and prices adjust at the contract or season boundary.
Modeling that sequence beats a single pass through percentage. Build scenarios by product line with its own exposure and elasticity, and revisit quarterly as competitor behavior reveals the true market pass through rate in your category.
Watching the category, not just your costs
Your correct price depends on the market new cost floor. Track competitor price moves, retailer margin behavior, and promotional depth after a tariff lands; shrinking promotions are often the first form pass through takes, before list prices move at all.

Distributors and retailers add their own layer: each intermediary decides its own split, so the shelf price change can exceed or trail the importer move. Mapping the chain explains surprises, like a ten percent duty becoming four percent at shelf after two absorption points, or sixteen after percentage markups compound it.
Communicating the adjustment well
Give customers time, a reason, and a number: notice periods that respect their budgeting, a plain explanation tied to the published tariff action, and the exact effective date and scope. B2B buyers who must explain the increase internally need that material from you, in writing, before the invoice surprises them.
Keep the door open on mitigation: shared sourcing changes, specification adjustments, or volume commitments that reduce the increase tie the customer to you through the adjustment. A tariff conversation handled well can deepen a commercial relationship; handled silently, it starts the search for your replacement.
Frequently asked questions
Why do some brands absorb tariffs while others pass them on?
Exposure and positioning differ. A brand whose rivals import from untaxed sources cannot raise prices without losing share, so it absorbs or redesigns sourcing. A brand competing against equally taxed rivals can pass most of the cost on, because the customer alternatives all rose too.
Should we announce tariff price increases to customers?
Transparency usually beats surprise: a dated notice explaining the increase, its cause, and its size preserves trust better than silent shelf price drift, especially in B2B relationships. Some brands label the tariff portion explicitly; others fold it into a general adjustment. Either way, unexplained jumps invite customers to assume opportunism.
How do contracts affect pass through timing?
Fixed price contracts delay pass through until renewal or an escalation clause triggers, concentrating the adjustment later. Cost plus and indexed contracts pass quickly. Knowing your contract mix tells you the lag between a tariff taking effect and its appearance in your realized prices.
Does pass through differ for services and digital goods?
Direct tariff exposure is mostly a physical goods story, but pass through arrives indirectly through hardware, data center equipment, and supplier pricing. The analysis is the same one step removed: map which of your suppliers carry tariff costs and what their contracts let them do about it.
