Part of The Manufacturer's Complete Guide to Selling Automotive Products to US Retail, the operator's playbook covering retailer landscape, line review, ACES/PIES, EDI, slotting, packaging, and launch sequence.
Present a landed cost, not a factory price: the full per unit cost delivered to the retailer's door, including duty and freight, with a written rule for how it adjusts if tariffs change. Buyers reward a cost that holds for a reset cycle.
Why tariffs became a line review issue
A line review is the formal session where a retailer's category team compares vendor submissions on cost, margin, and program terms and decides what earns shelf space. For years, import duty was a footnote in that conversation. Today it can swing a vendor's margin by double digits, and buyers know it.
Here is what the buyer is protecting. Once a reset is set, the planogram, the shelf tag, and the retail price are locked for months. If your cost moves after the set date, the buyer absorbs the margin hit or reopens pricing with a pricing team that does not enjoy reopening anything. The Auto SKUS Group has sat through hundreds of these sessions, and the vendors who lose on cost are rarely the most expensive ones. They are the ones whose number the buyer does not trust to hold.
That trust gap is the opening. If you can show exactly how your cost is built and exactly what moves it, you look like the lowest risk partner in the room, even next to a competitor with a lower headline price.
Build the landed cost before you build the deck
Landed cost is the total per unit cost of getting a product from the factory to the retailer's distribution center. Three terms matter. FOB, short for free on board, is the price at the factory or port before shipping. Customs value is the declared value of the goods that duty is calculated on. Duty is the percentage of that customs value paid to the government at the border.
Use an illustrative composite to see how fast the math changes. Say a windshield treatment item has a FOB cost of $3.10 per unit. Freight, port fees, and handling add $0.20. At a 25 percent duty rate, duty adds $0.775 per unit (25 percent of $3.10). Your landed cost is $4.075 per unit.
Now set the shelf. The retail price is $7.99 and the buyer's target margin is 35 percent, so the retailer's cost can be no higher than $5.19. You offer $5.15, which gives the retailer a 35.5 percent margin. Your margin on that sale is $1.075, or 20.9 percent. Without the duty, your landed cost would be $3.30 and your margin would be $1.85, or 35.9 percent. The tariff took 15 points out of your margin on a single item.
On a program of 40,000 units a year, that duty line alone is $31,000. Buyers who see that number in your submission understand that you have done the work. Buyers who do not see it assume you have not, and they discount your forecast accordingly. For the full sequence of what a buyer expects in a submission, the line review playbook maps each stage from first meeting to first PO.
Offer a cost that holds, with a rule for when it moves
The mistake most manufacturers make is quoting one number and hoping. The better move is to quote one number and a formula.
State your cost as firm for a defined window, typically through the first full reset cycle or 90 days from the PO. Then put a single adjustment rule in writing. If the published duty rate on your item changes by more than a stated threshold, your cost adjusts by the change in rate multiplied by the customs value, nothing else. In the example above, every 10 point change in the duty rate moves your cost by exactly $0.31 per unit (10 percent of $3.10). The buyer can model that in thirty seconds.
This works because it converts an unknown into a bounded number. A buyer cannot approve an open ended risk, but can approve a cost with a known ceiling. It also protects you: you are not absorbing a rate change you cannot control, and you are not hiding a padded cost inside your price to cover the uncertainty.
Pair the formula with a second quote when you can. If you have a qualified alternate source, show a landed cost for it. Suppose an alternate origin lands at $4.30 per unit because the factory price is higher but the duty is lower. Your options on the page might read $5.15 from the primary source with the adjustment rule, or $5.40 from the alternate source with a tighter rule. Giving the buyer a real choice shifts the conversation from whether your price is too high to which risk profile the retailer prefers. The manufacturer hub covers how to structure sourcing conversations like this before the meeting.
What to avoid in the room
Do not blame tariffs for a cost increase without documentation. Buyers hear that line from every vendor, and the ones who accept it are the ones who see a duty classification, a customs value, and a rate on paper. If you cannot show the arithmetic, expect a pushback and a request to re quote.
Do not split the story across documents. The cost, the adjustment rule, and the forecast should sit on one page, because the buyer will copy that page into the vendor comparison. If the pieces are scattered, the buyer rebuilds them and gets something less favorable to you.
Do not forget the downstream effect on category math. A buyer thinks about margin dollars and inventory productivity together, so a cost that holds helps the retailer protect its return on inventory investment. The category management guide explains how buyers weigh those numbers against the rest of the assortment.
The standard to aim for
Treat your cost the way a buyer treats a planogram: as a commitment with a defined shape. A landed cost built from FOB, freight, and duty, a firm window, one adjustment rule, and an alternate source when you have one gives the buyer everything needed to say yes. It also gives you a position you can defend when conditions move, because you named the rule before the market tested it.
Frequently asked questions
Should I quote FOB or landed cost to a retail buyer?
Quote landed cost, which is the total delivered cost including freight and duty. A buyer compares vendors on what the product costs at the distribution center, so a FOB price alone hides the real number and invites a re quote later.
How do I handle a tariff change after a buyer approves my cost?
Use a pre written adjustment rule. State that your cost moves only by the change in duty rate multiplied by the customs value, and only above a set threshold. Written before approval, it reads as a fair mechanism, not a surprise increase.
How long should a quoted cost stay firm in a line review?
Most manufacturers hold cost firm through the first full reset cycle or for 90 days from the first purchase order. Longer windows carry more risk for you, so pair them with an adjustment rule tied to a published duty rate.
Do buyers want to see an alternate sourcing option?
Yes, when it is qualified and priced. A second landed cost from a different origin shows the buyer you can protect supply and margin if duty rates shift, and it turns a price objection into a choice between two risk profiles.
