A tariff is a tax the U.S. government charges on goods imported into the country, and the U.S. importer of record — not the foreign factory — is the party that pays it to Customs and Border Protection, usually before the goods are released. For a small business, that means a tariff is not an abstract trade-policy headline; it is a real dollar amount added to the cost of every affected shipment, due at the border, often weeks before you sell the inventory it applies to. That timing gap is why tariffs land as a cash-flow shock first and a margin problem second. This guide explains how tariffs are calculated, who actually absorbs the cost, and the specific operating and financing moves owners use to protect margin and keep working capital intact.
Key takeaways
- A tariff is a tax on imported goods paid to U.S. Customs by the American importer of record — not by the foreign supplier.
- Duties are typically owed at the border when goods arrive, often weeks or months before you sell the inventory they apply to — which is why tariffs hit cash flow before margin.
- The HTS classification code determines your duty rate; a broker-verified, defensible reclassification is often the cheapest way to reduce tariff cost.
- Tariff cost is split among supplier, seller, and customer — but you still fund the full duty in cash up front and recover it slowly through sales.
- Revenue-based / MCA marketplace funding is underwritten on bank deposits and revenue rather than credit, with FICO 500+ often workable and amounts commonly starting near $10,000.
- Decisions on revenue-based capital typically come in 24 to 48 hours, matching the pace of a duty bill far better than a bank term loan; funding is never guaranteed.
- Bridge a tariff gap when the shortfall is a timing problem with inventory that turns quickly — not when the tariff made the product permanently unprofitable.
How a tariff actually works, step by step
A tariff is applied to the customs value of an import based on how the product is classified. The mechanics matter because each step is a place where cost is added or, occasionally, reduced.
- Classification (HTS code): Every product has a Harmonized Tariff Schedule code. The code determines the duty rate. Misclassification is one of the most common and expensive mistakes small importers make — the same item under two plausible codes can carry very different rates.
- Customs value: Duty is generally calculated on the transaction value of the goods (what you paid the supplier), not on freight or insurance in most cases. Getting the declared value right protects you both ways.
- Duty rate: This can be a standard Most-Favored-Nation rate, a country-specific additional tariff, or a special program rate. Rates stack — a base duty plus an added Section-based tariff can apply to the same shipment.
- Payment at entry: Your customs broker files the entry and the duties are typically owed at or shortly after the goods arrive, long before you have sold the inventory.
The practical takeaway: the tariff is due on a schedule set by the border, not by your sales cycle. That mismatch is the whole cash-flow story.
Who really pays a tariff — and why it feels like a margin cut
Legally, the U.S. importer pays. Economically, the cost gets split among three parties in proportions you negotiate and the market allows: the supplier (if you can push for a price concession), you (as absorbed margin), and your customer (as a price increase). Most small businesses cannot fully pass the cost downstream immediately, so a meaningful share lands on their own margin in the short term.
Here is the part owners underestimate: even if you eventually raise prices and recover the margin, you still had to fund the duty in cash at the border. You paid the government today and you will recover it from customers over the next 60, 90, or 120 days as you sell through. That funding gap is working capital, and it is exactly the pressure point a tariff creates.
The real problem is timing, not just cost
Break a tariffed purchase into a timeline and the issue becomes obvious. You place an order, pay a deposit, the goods ship, they arrive, you pay the duty at entry, the inventory sits, you sell it, and finally the cash comes back — often net-30 or net-60 if you sell wholesale. From the day you fund the duty to the day the cash returns can easily be two to four months.
During that window your cash is locked inside inventory and receivables. Run two or three tariffed orders in a row and a healthy, profitable business can still run tight on cash. This is why owners who are still profitable on paper suddenly feel squeezed after a tariff increase: the P&L looks fine on an annual basis, but the cash conversion cycle stretched and the bank balance shows it.
Operating moves to reduce tariff exposure
Before you finance the gap, shrink it. These are the levers that reduce how much tariff you fund and how long your cash stays trapped.
- Verify your HTS classification. Have a licensed customs broker confirm the code. A defensible reclassification, where the product genuinely fits a lower-rate code, is the cheapest cost reduction available.
- Negotiate cost-sharing with suppliers. A supplier facing a lost account will often absorb part of the increase or extend payment terms. Every dollar of deposit or landed cost you defer is a dollar you do not have to fund.
- Diversify sourcing. A second supplier in a lower-tariff country protects you from a single-country rate hike, even if you keep most volume with the incumbent.
- Explore duty programs. Foreign-trade zones, bonded warehouses, and duty drawback (for goods you re-export) can defer or recover duty. These fit higher-volume importers but are worth a conversation with your broker.
- Re-price deliberately, not in a panic. Segment your catalog. Pass through on price-inelastic and low-visibility SKUs first; hold the line on the price-sensitive items that drive traffic.
Financing the gap: how revenue-based funding fits
When you have squeezed the operating levers and still face a duty bill that lands months before the cash returns, the question becomes how to bridge it without starving the rest of the business. A bank line is the cheapest answer when you can get one, but underwriting is slow and heavily credit- and collateral-driven — not much help when a shipment is due at the port this week.
A revenue-based financing or MCA marketplace is built for that specific timing problem. Approval is driven by your bank deposits and revenue trend rather than your credit score, so a strong sales history can carry the file even with a FICO in the 500s. Funding amounts typically start around $10,000 and decisions commonly land in 24 to 48 hours, which matches the pace of a duty bill far better than a term-loan application. Repayment flexes as a set share of daily or weekly deposits, so the cost of capital tracks your actual sales rather than a fixed amortization that ignores a slow week. It is not the right tool for a permanent margin problem, and it is never guaranteed — but for funding a duty payment while inventory sells through, the speed and revenue-first underwriting fit the job. For the fuller picture, see our guides to revenue-based financing and working capital for small businesses.
Decision framework: when bridging a tariff makes sense
Financing a tariff gap is a good decision or a bad one depending on the shape of the problem. Use this framework before you fund.
Works best when:
- The tariff created a one-time or seasonal cash gap, not a permanent margin loss — you can sell the inventory through and recover the cost in price.
- Your deposits are steady and provable, so revenue-first underwriting works in your favor.
- The inventory turns in weeks, not many months, so the financed cost is short-lived.
- You have a clear path to re-price or share cost with the supplier, so the bridge is temporary by design.
Avoid when:
- The tariff made the product structurally unprofitable and no realistic price increase fixes it — financing only delays the loss.
- You are already stacking short-term advances and daily remittances are choking operations.
- The inventory is slow-moving or speculative, so the cash stays trapped far longer than the financing horizon.
- You cannot answer, in one sentence, how and when this specific inventory pays the funding back.
A worked example: funding the duty on one order
Figures below are illustrative, for example only, to show the shape of the decision — not a quote.
| Item | Before tariff | After tariff increase |
|---|---|---|
| Order cost (goods) | $40,000 (for example) | $40,000 (for example) |
| Duty at the border | $3,000 (for example) | $9,000 (for example) |
| Cash due before you sell anything | ~$43,000 | ~$49,000 |
| Days until inventory sells through | ~60 (for example) | ~60 (for example) |
| Extra cash you must fund up front | — | ~$6,000 gap |
The added duty in this example is roughly $6,000 you now have to find at the border, months before the customers who ultimately pay for it hand you the cash. If those goods reliably sell through in about two months, bridging that gap with short-term, revenue-based capital can be a reasonable trade: you keep the shipment moving, protect supplier relationships, and repay as the sales that justified the order actually arrive. If the goods might sit for six months, the same bridge becomes an expensive way to store inventory — which is exactly the distinction the decision framework above is meant to force.
Frequently asked questions
Do foreign suppliers pay the tariff, or do I?
You do. Legally the U.S. importer of record pays the duty to Customs, usually at or shortly after the goods arrive. You may negotiate a price concession from your supplier to share the cost, but the payment obligation at the border is yours, and you fund it before you sell the inventory.
Why do tariffs feel like a cash-flow problem more than a cost problem?
Because of timing. You pay the duty at entry but recover it slowly as you sell through and collect from customers — often 60 to 120 days later. Even if you eventually raise prices and keep your margin, your cash is locked in inventory and receivables in the meantime. That funding gap is the core small-business tariff problem.
What is the single cheapest way to reduce tariff cost?
Verify your HTS classification with a licensed customs broker. Products are sometimes filed under a higher-rate code than they legitimately qualify for. A defensible reclassification lowers the duty rate on every future shipment at effectively no ongoing cost, which is why it should come before any financing decision.
Should I raise prices to cover a tariff?
Usually in part, but deliberately rather than across the board. Segment your catalog: pass the cost through first on low-visibility, price-inelastic SKUs and protect the price-sensitive items that drive traffic. Full immediate pass-through is rarely possible, which is why most owners absorb some margin short-term and finance the gap while they re-price.
How can revenue-based financing help with a tariff bill?
It funds the cash gap between paying duty at the border and collecting from customers. Approval is based on your bank deposits and revenue rather than your credit score, amounts commonly start around $10,000, and decisions often come within 24 to 48 hours — fast enough to fund a shipment due at the port. Repayment flexes with your sales. It fits a timing gap, not a permanent margin loss, and it is never guaranteed.
Can I qualify with a low credit score?
Often yes. Revenue-based and MCA marketplace funders underwrite primarily on provable bank deposits and revenue trend, so files with a FICO in the 500s can still work when sales are steady. Consistent, verifiable deposits matter more than the credit number, though approval always depends on the full picture and is never automatic.
When should I NOT finance a tariff gap?
When the tariff made the product structurally unprofitable and no realistic price increase fixes it, when the inventory is slow-moving so your cash stays trapped far longer than the financing horizon, or when you are already stacking short-term advances and daily remittances are choking operations. In those cases financing delays a loss rather than bridging a timing gap.
Are tariff rates the same for every country and product?
No. Rates depend on the product's HTS code and the country of origin, and they stack — a base duty plus an added country- or program-specific tariff can apply to the same shipment. This is why diversifying to a second supplier in a lower-tariff country, and confirming both classification and origin, are core defensive moves.
