Key Takeaways
If you've been dealing with tariffs lately, you've probably felt that creeping sense of dread every time a shipment crosses the border. Maybe you've had a part arrive with an unexpected 25% duty despite having correct country of origin documentation. Maybe a repair sent to Canada got stopped at the border because nobody flagged the tariff exposure beforehand. As one customs broker noted in a popular trade compliance thread, "it seems like no one knows what's supposed to be tariffed or not."
The gut reaction for many companies is to look at reshoring, supplier diversification, or nearshoring — all legitimate strategies, but none of them are quick or cheap. Overhauling your supply chain takes years and millions of dollars, and it still doesn't recover the duties you've already paid.
This article focuses on what you can do right now — tariff mitigation strategies that work with your existing supply chain, not against it. Some prevent overpayment from the start. One actually puts cash back in your account.
Before chasing refunds, make sure you aren't overpaying in the first place. These strategies don't require changing suppliers, renegotiating contracts, or restructuring logistics — they require digging into your documentation and understanding the rules more precisely.
Every product you import is assigned a Harmonized Tariff Schedule (HTS) code, and that code determines your duty rate. Misclassification is more common than most importers realize — and it almost always results in overpayment rather than underpayment, because conservative classification tends to default to higher-duty categories.
A thorough HTS audit by a qualified customs professional can identify reclassification opportunities that reduce your duty rate, sometimes dramatically. According to WG Consulting, correct tariff code optimization has been shown to reduce duties from double digits to near zero for some product categories. That's not a loophole — it's applying the correct classification to begin with.
Start here: conduct a comprehensive tariff impact assessment across your import portfolio. Identify your highest-volume, highest-duty lines and focus the classification review there first.
The U.S. maintains a number of trade programs and agreements that can reduce or eliminate duties on qualifying goods — without requiring you to change where you source them.
Understanding which program applies to your specific trade flow — temporary exports, repairs, FTZ storage — is where a good customs broker earns their fee. As the r/CustomsBroker community makes clear, the rules exist, they're just not intuitive. Knowing to reference 19 CFR 10.8 for articles exported for repairs, for instance, can mean the difference between a full 25% duty and a much smaller bill.
Tariff engineering is the legal practice of modifying a product's design, composition, or manufacturing process so it qualifies for a lower HTS tariff classification. This might mean changing materials, adjusting assembly sequencing, or shipping components separately for final U.S. assembly rather than importing a finished product.
It's not for every company, and it requires close collaboration between product design, legal counsel, and customs experts to ensure the modification is genuine and defensible. But for companies paying significant duties on high-volume products subject to Section 301 tariffs, even a modest reclassification can recover millions annually. Plante Moran's guidance on tariff mitigation specifically highlights this as an under-leveraged strategy for manufacturers facing sustained tariff exposure.
The strategies above help you reduce future tariff exposure. But what about the duties you've already written checks for? There's a U.S. government program designed specifically to refund them — and most companies have never used it.
Duty drawback, authorized under 19 U.S.C. § 1313, is a refund of up to 99% of customs duties, fees, and taxes paid on imported goods that are subsequently exported, used in a U.S. manufacturing process for export, or destroyed. It's been part of U.S. trade law for decades. And yet, an estimated $15 billion in eligible tariff refunds go unclaimed every year — roughly 80% of all eligible import refunds that companies never collect.
The reason so much money goes unclaimed isn't that companies don't qualify. It's that the traditional drawback process is slow, manual, and opaque — and most companies have been told it isn't worth the effort.
Eligibility is broader than most importers assume. There are three main drawback types under U.S. law:
If your business involves any combination of importing and exporting (or importing and destroying unsold/defective goods), you may qualify under one or more of these categories. The key requirement is documentation — you need to connect the imported merchandise to the export or destruction event.
Generally, claims must be filed within the statutory time limits — typically 5 years from import and 3 years from export, though specific rules vary by drawback type. That means duties paid in prior years may still be recoverable, depending on your timeline.
Knowing you're eligible for drawback and actually claiming it are two different problems. The traditional drawback process has kept a significant portion of eligible companies from ever filing.
The result: most mid-market manufacturers and distributors either don't know they're eligible, assume the process isn't worth pursuing, or get quoted minimum thresholds that exclude them entirely.
The difference in outcomes is significant. In head-to-head comparisons, algorithmic optimization recovers 15–20% more in refunds than the manual matching methods that legacy providers rely on — because a computer can evaluate millions of import-export combinations exhaustively, while a human working in Excel cannot.
Tariffs don't have to be a permanent sunk cost. A layered approach — fixing HTS classifications, using the right trade programs, and filing for duty drawback on eligible activity — gets you much further than any single tactic alone.
The biggest gap for most companies isn't strategy. It's execution. HTS audits require customs expertise. FTZ and TIB programs require careful documentation. And duty drawback has historically required resources that most mid-market companies simply don't have.
That's the problem we built Zollback to solve — specifically on the drawback side, where the gap between what companies are owed and what they actually recover is widest. Our platform ingests your trade documents in any format, runs proprietary optimization algorithms to find the maximum refundable duties, has every claim reviewed by our in-house licensed customs brokers, and files directly with CBP via certified Automated Broker Interface (ABI) software. Our pricing is entirely performance-based — no upfront fees, no retainers. We earn only when you get cash back.
If you're importing and exporting — or importing goods that sometimes get destroyed or returned — it's worth finding out what you may be leaving on the table. Check your drawback eligibility with a free assessment and get a refund estimate before committing to anything.
Duty drawback is a U.S. government program that provides a refund of up to 99% of customs duties paid on imported goods that are later exported or destroyed. It allows companies to recover tariffs they have already paid, turning a sunk cost into a cash recovery. The program covers manufacturing, unused merchandise, and rejected merchandise scenarios.
Any company that imports goods and subsequently exports them (or similar goods) or destroys them may be eligible for duty drawback. This includes manufacturers who use imported parts in exported products, distributors who re-export inventory, and retailers who destroy defective or returned merchandise.
An estimated $15 billion in drawback refunds go unclaimed annually because the traditional process is extremely complex, slow, and manual. Historically, the extensive documentation and data matching requirements made it too resource-intensive for many companies, especially small and mid-sized businesses, to pursue claims.
AI-powered automation makes the duty drawback process faster, more accurate, and accessible to companies of all sizes. Our technology ingests trade data in any format, algorithmically matches imports to exports to maximize your refund, and prepares claims in days, not months. This often results in a 15-20% higher recovery.
Companies can generally file duty drawback claims for up to five years after the import date and three years after the export date. This five-year lookback period means you may be able to recover significant duties paid in previous years, providing a substantial cash flow opportunity from past activities.
You will need documentation that proves the import, export (or destruction), and the link between them. Key documents typically include commercial invoices, packing lists, bills of lading (for both import and export), and proof of export. Our platform can ingest these documents in any format.
Zollback operates on a performance-only basis, meaning there are no upfront fees, retainers, or subscription costs. We only earn a percentage of the refund you successfully recover from U.S. Customs and Border Protection (CBP). If you don't get paid, neither do we. A free eligibility assessment can estimate your potential refund.
