Tariffs Just Hit Your Cost of Goods: A Calm, Practical Playbook for Sellers

When tariffs rise on the goods you import, your cost of goods sold goes up overnight on products you've already committed to — and the headlines make it feel like an emergency. It isn't, if you respond with a plan instead of a reflex. The two reflexive moves both hurt: panic-raising prices loses you the Buy Box and rank, while silently absorbing the cost can quietly turn your best sellers into break-even or loss-making SKUs. The sellers who come through a tariff shock intact treat it as a margin problem to be managed across sourcing, pricing, and product mix — not a fire to be put out in a day. This is that playbook.

First, recalculate your real landed cost per unit

You can't make a good decision on a number you haven't updated. A tariff increase changes your landed cost — the all-in cost to get one sellable unit into the warehouse, including the product price, freight, insurance, customs duties, and the new tariff. Rebuild that figure per SKU with the new duty applied, then recompute your true net margin after the marketplace's referral and fulfillment fees. Only then can you see which products still clear a healthy margin, which are now marginal, and which have flipped underwater. Without this step you're guessing — and the SKUs that quietly went negative are the ones that do the most damage, because volume on a loss-making product accelerates the bleed.

Don't reprice everything in a panic

The instinct to immediately pass the full tariff onto every price is usually wrong. A sharp price jump can knock you out of the Buy Box, suppress conversion, and cost you rank — sometimes losing more in volume than the tariff ever cost you in margin. Be surgical instead. Some products have the demand and differentiation to absorb a price increase without much volume loss; others are price-sensitive commodities where even a small bump tanks sales. Raise prices where the product can carry it, hold the line where it can't, and lean on the levers below for the rest. A modest, well-placed increase plus cost savings elsewhere usually beats a blunt across-the-board hike.

Levers to protect margin beyond price

Price is one lever, not the only one. Before you decide how much to pass on, work through the rest — most tariff damage can be split across several smaller adjustments that customers barely feel.

• Renegotiate with your supplier — a tariff squeezes them too, and many will share some of the pain through a lower unit price or better terms rather than lose your volume.
• Diversify sourcing — explore suppliers in countries with lower duty exposure, or domestic options where the math works, so a single country's tariff doesn't dictate your whole catalog.
• Trim avoidable costs — right-size your packaging to drop a fulfillment size tier, consolidate freight, and cut prep fees, recovering margin the tariff took.
• Reconsider order quantities — buying inventory before a scheduled tariff hike (where you have the cash and storage) can lock in the old cost on a batch, though watch storage fees and demand risk.
• Shift your product mix — promote and reorder the SKUs that still carry strong margins after the tariff, and de-emphasize the ones that no longer pencil out.

Diversify sourcing for the long term

A tariff shock is a lesson in concentration risk. If your entire catalog ships from one country, a single policy change can reset your cost base overnight with nothing you can do about the inventory already on the water. Over time, building relationships with suppliers across more than one region — or qualifying a domestic backup for your most important SKUs — turns that single point of failure into a manageable variable. Diversifying isn't free; it takes sourcing effort, sampling, and qualification work, and a second supplier may not match the first on price. But the resilience pays off the next time trade policy moves, which it inevitably will. Treat supplier diversity as insurance you build before you need it.

Watch competitors, but don't follow blindly

Everyone selling imported goods feels the same tariff, so the whole category's cost base shifts together. That can be an opportunity: if competitors panic and overshoot on price, a seller who's recomputed their landed cost and holds a steadier, sustainable price can win share. If competitors are slow to react and prices stay artificially low across the category, racing them to the bottom only locks in losses for everyone. Watch how the category moves, but anchor your own pricing to your real margin math, not to what the seller next to you is doing. The point of recalculating landed cost is so you can act on knowledge while others act on nerves.

Frequently asked questions

Should I raise prices the moment a tariff takes effect?

Not reflexively, and not on everything. A blunt across-the-board increase can cost you the Buy Box, conversion, and rank — sometimes losing more in volume than the tariff cost in margin. Recompute your landed cost and net margin per SKU first, then raise prices selectively on products that can carry it, hold the line on price-sensitive ones, and recover the rest through supplier negotiation and cost cuts. A measured response beats a panic hike almost every time.

Is buying inventory ahead of a tariff increase a good idea?

It can be, if a hike is scheduled and you have the cash and storage capacity. Buying a batch at the current duty locks in the old landed cost for that stock and buys you time to adjust. But it's a bet — you take on storage fees, the risk that demand softens, and the risk of sitting on excess. Size any pre-buy to a SKU you're confident will sell through, not your whole catalog, and net out the extra storage cost before deciding.

How do tariffs change which products I should keep selling?

They reshuffle your profit ranking. A SKU that was a solid earner can become marginal or unprofitable once a higher duty hits its landed cost, while a product with more pricing power or a less-affected supply chain holds up. After a tariff change, re-rank your catalog by true net margin and steer your reorders, ad spend, and promotions toward the SKUs that still pencil out — and consider phasing out the ones that no longer do.
