How Tariffs Are Making Secondhand Explode in 2026 (And Why Resellers Should Care)

If you've noticed your eBay and Poshmark sales picking up in early 2026, it's not your imagination — and it's not just because you've gotten better at listing. The entire secondhand market is riding an economic wave that started with tariffs, got amplified by a Supreme Court ruling, and shows no signs of slowing down until at least July.

Here's what happened, why it matters to you as a reseller, and — most importantly — what you should be doing about it right now.

The Timeline: How We Got Here

Throughout 2025, tariffs imposed under the International Emergency Economic Powers Act (IEEPA) pushed import duties on Chinese goods to historic levels. The average effective tariff rate hit 16.0% — the highest since World War II. Clothing and textiles were especially hard-hit, with estimated short-term consumer price increases of 65% for clothing and 87% for leather goods like shoes and handbags.

Then on February 20, 2026, the Supreme Court struck down IEEPA tariffs in a 6–3 decision, ruling that the law doesn't actually authorize the president to impose tariffs. Within days, the administration imposed new 15% global tariffs under Section 122 of the Trade Act of 1974 — a more limited authority that expires automatically on July 24, 2026, unless Congress extends them.

The current situation: tariffs are lower than their peak, but still historically high. The average effective rate sits between 9.1% and 13.7% depending on which calculations you use. New retail goods — especially clothing, shoes, electronics, and home goods — remain significantly more expensive than pre-tariff levels.

What This Means for the Secondhand Market

The data is clear: tariffs are the single strongest tailwind the resale industry has ever experienced.

According to ThredUp's 2025 Resale Report, the US secondhand apparel market grew 14% in 2024 — five times faster than broader retail. Online resale grew 23%, which is 8x faster than apparel retail overall. A record 58% of shoppers bought secondhand in 2024. And that was before the tariff impact fully hit consumer behavior.

The tariff acceleration is dramatic: 59% of consumers now say they'll actively seek secondhand goods if tariffs raise retail prices. Among Millennials, that number jumps to 69%. Consumers plan to spend 34% of their apparel budget on secondhand in the next 12 months — rising to 46% among Gen Z and Millennials.

ThredUp's Chief Strategy Officer put it bluntly: "Resale is actually in the strongest position it's ever been in right now."

The US secondhand market is projected to reach $74 billion by 2029, with online resale expected to nearly double to $40 billion. The global secondhand apparel market is on track to hit $367 billion by 2029.

The Supply Side: A Hidden Constraint

Here's the nuance most reselling content misses: tariffs don't just create more buyers — they may also constrain supply. In tighter economic times, Americans have historically been more hesitant to donate clothes and goods. If people are feeling financially squeezed, they're less likely to clean out their closets for Goodwill. Less donation = less inventory at thrift stores.

This creates an interesting dynamic for garage sale flippers specifically. While thrift store inventory may tighten, garage sale inventory is driven by life events — moving, downsizing, spring cleaning, estate liquidation. These happen regardless of economic sentiment. Garage sales and estate sales may become the more reliable sourcing channel in a supply-constrained environment.

The Reseller's Action Plan for the Tariff Window

The Section 122 tariffs expire July 24, 2026. Congress may or may not extend them. Either way, the current elevated demand for secondhand goods is time-bounded. Here's how to capitalize.

1. Stock Up on Inventory Now

Garage sale season is opening right as buyer demand is peaking. The items you source in April and May will sell into a market where buyers are actively seeking alternatives to expensive new goods. Focus on categories where the tariff impact is most visible: brand-name clothing, shoes, leather goods, and home electronics. These are the categories where new retail prices have increased the most, making your secondhand pricing look even more attractive.

2. Adjust Your Pricing Upward (Carefully)

When new retail prices go up, secondhand prices follow — but with a lag. Many resellers are still pricing based on 2024–2025 comps. Check sold listings on eBay from the last 30 days, not the last 90 days, to see if your category has shifted. Premium brands like Patagonia, lululemon, and Le Creuset may have moved up 10–20% in resale value as buyers who used to buy new are now shopping secondhand.

3. List on Multiple Platforms

More buyers are entering the secondhand market than ever before, and they're spread across platforms. A buyer who previously only shopped retail might start on Facebook Marketplace (lowest barrier) before discovering Poshmark or Depop. Cross-list everything — use our platform comparison to match items to the right marketplace, and consider a cross-listing tool to push inventory everywhere simultaneously.

4. Target Tariff-Sensitive Categories

5. Position Your Listings for Tariff-Aware Buyers

You don't need to mention tariffs in your listings — that would be weird. But you can lean into the value proposition. Phrases like "Save vs. retail," "Fraction of original price," and "Like-new condition" resonate more strongly when buyers are feeling price-conscious. Include the original retail price when you know it, so the savings are obvious.

What Happens After July 24?

Honestly? Nobody knows. The Section 122 tariffs expire automatically after 150 days unless Congress passes extension legislation. If tariffs drop significantly, some of the secondhand demand boost will soften. If Congress extends or expands tariffs, the boom continues.

But here's the thing: secondhand shopping habits are sticky. ThredUp's data shows that once consumers discover the value of resale, they don't go back to exclusively buying new. The tariff era is creating millions of new secondhand shoppers who will continue shopping secondhand even if tariffs normalize. You're not just catching a wave — you're building an audience that will stick around.

The Bigger Picture: 2026 Is the Year to Get Serious

Between tariff-driven demand, the eBay–Depop acquisition creating a mega-platform, Poshmark's algorithm overhaul, and USPS actually lowering rates for heavy packages — the stars are aligning for resellers in a way that doesn't happen every year. If you've been thinking about scaling from casual to serious, garage sale season 2026 is your on-ramp.

The inventory is at garage sales. The buyers are online. The window is open. The only question is whether you're going to walk through it.
