If your business is feeling the squeeze from rising tariffs, you’re not alone. In 2025, U.S. trade policy is once again front and center, with escalating duties on Chinese EVs, retaliatory tariffs from the EU, and growing uncertainty around digital services taxes. For importers, these shifting rules aren’t just theoretical—they’re already hitting the bottom line. Margins are tighter. Compliance is trickier. And with election-year politics fueling protectionist sentiment on both sides of the aisle, it’s unlikely things will stabilize anytime soon.
In this environment, tariff-saving strategies aren’t just nice to have—they’re essential. The smartest importers in 2025 aren’t just cutting costs; they’re claiming refunds, restructuring supply chains, and proactively reducing duty exposure before goods even hit the port. Whether you’re dealing with newly reinstated Section 301 tariffs, complex multi-tiered transactions, or simply trying to reclaim value from unused merchandise, there are now more tools than ever to reduce your tariff burden—legally and effectively.
From duty drawback programs governed by 19 CFR 190, to creative tariff engineering tactics and the often-overlooked First Sale Rule, today’s importers have a range of options to mitigate risk and unlock refund potential. But navigating these opportunities requires more than gut instinct. It demands data, automation, and a sharp understanding of how Customs and Border Protection (CBP) is enforcing claims in the ACE era.
This guide will walk you through the most effective tariff mitigation strategies in 2025. We'll break down how duty drawback works under the TFTEA framework, how tariff engineering is being used to reclassify goods for legitimate savings, and how importers are using documentation-based strategies like the First Sale Rule to lower dutiable value. We'll also explore emerging best practices for staying compliant while maximizing refund value—so you can stop overpaying and start reclaiming what's yours.
Because in 2025, the difference between surviving and thriving often comes down to one thing: how well you understand your duty recovery options.
Duty Drawback 101—The Cornerstone of Tariff Refunds
In a year defined by rising tariffs and tightening margins, duty drawback remains the most powerful tool importers have to recover costs. With refund potential as high as 99% of duties, taxes, and fees paid on imported goods, it's no wonder more companies are making drawback a core part of their tariff mitigation strategy in 2025. But while the concept is straightforward, executing a successful drawback claim requires both regulatory knowledge and airtight data discipline.
What is Duty Drawback and Why Does it Matter in 2025?
Duty drawback is a long-standing U.S. Customs program that allows companies to reclaim duties paid on goods that are later exported, destroyed, or used in manufacturing exported products. It’s governed by 19 CFR Part 190, modernized under the Trade Facilitation and Trade Enforcement Act (TFTEA) to streamline the process and expand eligibility.
As tariffs spike on high-volume categories like electronics, EV parts, and apparel, drawback has become a high-impact strategy for reclaiming costs without changing sourcing or pricing. For importers dealing with Section 301 or Section 201 tariffs, drawback often means the difference between breaking even and bleeding margin. Section 232 duties usually need a separate strategy because the Section 232 duty amount is generally not drawback-eligible.

The Main Types of Duty Drawback
Under TFTEA, drawback is now categorized into a few primary types:
- Unused Merchandise Drawback: For goods that are imported and then either exported in essentially the same condition or destroyed under U.S. Customs supervision.
- Manufacturing Drawback: For goods that are imported, used to produce a finished item, and then exported.
- Rejected Merchandise Drawback: For goods that are returned or destroyed due to defect, non-conformance, or refusal by the buyer.
Each duty drawback type comes with its own requirements for documentation and matching exports to imports, but all can be submitted through a single unified framework under ACE.
What Changed Under TFTEA and 19 CFR 190
The passage of TFTEA was a turning point. Before 2016, drawback claims were fragmented across multiple regulatory parts. TFTEA consolidated the rules into 19 CFR Part 190, introduced a standardized claim format, and extended the timeline to file from three to five years from the import date.
But TFTEA also raised the bar. Claims now require stricter recordkeeping and electronic submission through ACE, Customs and Border Protection’s (CBP) digital platform. Importers need to tie every refund request to a validated import-export pair, backed by clean documentation and up-to-date sourcing records.
How to Qualify—and Common Mistakes to Avoid
Eligibility for duty drawback hinges on two factors: whether you paid duties on eligible imports, and whether those goods were subsequently exported, destroyed, or transformed into exported products. Companies must maintain detailed documentation, including commercial invoices, bills of lading, and CBP entry records, and keep those records organized through the post-liquidation retention period.
Many businesses leave money on the table by assuming they aren’t eligible—or by working with brokers who lack ACE access or claim optimization tools. Common pitfalls include:
- Missing export documentation
- Poor record matching between import and export
- Filing claims too late (past the 5-year window)
- Relying on manual processes that trigger CBP rejections
This is why working with a professional drawback filer matters. It’s not just about filing paperwork—it’s about proving eligibility under scrutiny.
Where Technology Makes the Difference
Filing drawback through traditional brokers often means manual entry, limited visibility, and delayed claims. In contrast, platforms that integrate directly with ACE and automate claim matching can streamline the process, ensure accuracy, and surface refunds a human might miss.
Pax AI’s system, for instance, uses machine learning to find overlooked claims, optimize matching logic, and track submissions in real-time—maximizing both speed and refund value. Our clients often discover six-figure savings they didn’t know they were eligible for.
Why Duty Drawback Should Be a Priority in 2025
With tariffs increasing across key categories—and retaliatory duties from trading partners growing more complex—duty drawback offers a way to recover sunk costs without altering your sourcing strategy. It’s one of the few tools that rewards good documentation and proactive compliance with real, recurring cash.
In 2025, CBP audits are becoming more automated, more frequent, and more data-driven. Filing correctly and consistently isn’t just best practice—it’s a form of risk management. Duty drawback isn’t a loophole. It’s your legal right to recover what’s yours.
Tariff Engineering and Post-Entry Optimization
If you’ve ever tried to reduce duty costs by modifying your products before they hit U.S. shores, you’ve already used one of the oldest tools in the trade compliance playbook: tariff engineering. And for many companies, it works. In industries like footwear, apparel, auto parts, and electronics, tariff engineering can meaningfully reduce landed costs—sometimes by double-digit percentages.
But in 2025, tariff engineering alone isn’t enough. With tariffs climbing across everything from EV batteries to consumer electronics, companies are increasingly looking beyond pre-entry classification strategies and toward post-entry optimization—especially through smarter use of duty drawback. In many cases, that’s where the largest, most scalable savings opportunities live.
What is Tariff Engineering?
Tariff engineering is the practice of modifying a product before it enters the U.S. in order to qualify for a more favorable Harmonized Tariff Schedule (HTS) classification. It’s completely legal—as long as the product’s form at the time of entry truthfully reflects its classification. These modifications can involve physical changes, disassembly, or component swaps, all aimed at reducing the duty owed.
Common examples include:
- Footwear companies adding decorative features to shoes to shift into a lower-duty category.
- Pasta manufacturers par-cooking noodles so they qualify as “prepared foods” instead of raw.
- Furniture or appliance brands shipping disassembled kits to avoid higher finished goods duties.
When done right, tariff engineering can reduce duty rates from 10–25% down to just a few percentage points—or even zero.
Why Engineering Alone Leaves Refunds on the Table
The limitation with tariff engineering is structural: it only applies before goods are entered. Once a shipment has cleared customs, that opportunity closes. And for companies importing complex goods, blended materials, or high-variability SKUs, reconfiguring a product just to qualify for a different HTS code isn’t always feasible—or worth the operational lift.
That’s where duty drawback comes in. Unlike tariff engineering, drawback happens after import. It allows companies to recover duties already paid on goods that are exported, destroyed, or used in exported manufacturing. When paired with strong recordkeeping and smart strategy, drawback can offer refund rates of up to 99%—no product redesign required.
And while many companies already claim drawback, most aren’t getting back nearly as much as they could. That’s because filing a claim is easy. Optimizing one is hard.
The Hidden Cost of Non-Optimized Refunds
Here’s the reality: most brokers match drawback claims using simple logic—first-in, first-out sequencing, HTS code groupings, and surface-level compliance checks. That approach is fine for filing—but it often fails to maximize refund value.
Take substitution drawback (J2), for example. Refunds are calculated based on the lower of the import or export value. So if your broker matches a $100 export to a $60 import, you’re only refunded on $60—even if a better match existed in your data. Over thousands of shipments, those mismatches quietly add up to serious money left behind.
By contrast, companies that layer optimization on top of engineering—or use it as their primary strategy when engineering isn't possible—are unlocking a second, often larger tier of duty savings. They're not just saving at entry. They're recovering value at exit, too.
How Optimization Complements Tariff Engineering
These strategies aren’t mutually exclusive. In fact, they work best in tandem. Tariff engineering is a great way to reduce costs on predictable, high-volume products. But refund optimization can capture savings across everything else—including blended inventory, export rejects, and dynamic product lines that don’t lend themselves to pre-entry manipulation.
If you’re already investing in tariff engineering, there’s a good chance your refund strategy deserves the same level of attention. And if engineering isn’t viable for your product or market, optimizing your drawback claims may be the most impactful lever available.
The First Sale Rule
Not all duty savings come from recovering money after the fact. Some start with how you structure your supply chain in the first place. That’s where the First Sale Rule comes in—a little-known but completely legal provision that allows importers to reduce the declared customs value of their goods by declaring the price of an earlier sale in the transaction chain.
If your company sources products through a multi-tiered structure—for example, a factory in Vietnam sells to a Hong Kong trading company, which then sells to your U.S. importer—the First Sale Rule might let you pay duty based on the factory price, not the marked-up invoice. And depending on your margins and volume, that difference could mean 10–20% in duty savings on every shipment.
How the First Sale Rule Works
The First Sale Rule allows importers to declare the value of goods based on the first sale for export to the United States—rather than the last sale to the U.S.-based buyer. In a multi-tiered transaction, that often means choosing the lower price charged by the original manufacturer, rather than the intermediary reseller or trading house.
To qualify, the importer must prove that the first sale was a legitimate, arm’s-length transaction, and that the goods were clearly destined for the U.S. at the time of that sale. That means thorough documentation is key—purchase orders, invoices, payment records, shipping instructions, and contractual language all matter.
If accepted by Customs, this lower declared value reduces the duty owed at the time of entry—without requiring any product changes, reclassification, or refund claims down the line.
Who Can Use It—and When It Makes a Difference
The First Sale Rule is most relevant to importers that buy through intermediaries, resellers, or global sourcing offices. It’s especially common in sectors like apparel, electronics, automotive parts, and general merchandise—industries where goods often pass through several hands before landing in the U.S.
The more layers between the factory and the importer, the more potential markup—and the more valuable the First Sale Rule becomes. For high-volume SKUs with consistent manufacturing partners, it can generate steady per-shipment savings that add up quickly.
And unlike some mitigation strategies, the First Sale Rule is repeatable. Once your documentation is in place and accepted by CBP, you can continue to apply it across future entries with confidence.
Challenges and Compliance Considerations
While powerful, the First Sale Rule isn’t a free pass. CBP scrutiny has increased in recent years, and importers need to be ready to prove the legitimacy of the first sale with clear, auditable documentation. Common pitfalls include vague or incomplete invoices, missing shipping terms, or intermediary contracts that blur the line between buyer and agent.
Additionally, Customs wants to see that the first sale was not influenced by the U.S. buyer—meaning price negotiations, design specs, and production instructions can’t come exclusively from the importer. If the U.S. buyer effectively controls the transaction, CBP may consider the intermediary sale the true dutiable transaction.
This is why many companies choose to obtain a binding ruling from CBP to confirm First Sale eligibility upfront—especially if they plan to rely on it long-term.
How It Fits into a Broader Duty Strategy
Like tariff engineering, the First Sale Rule reduces your duties before they’re paid. But unlike engineering, it doesn’t require changing the product itself—it simply changes the valuation method. And unlike drawback, it doesn’t rely on exports. That makes it a useful tool for importers with large domestic sales volumes who still want to reduce dutiable costs at the front end.
That said, First Sale and drawback can absolutely work together. In fact, they often do. By reducing duties at entry and optimizing refunds after export, companies can build a layered mitigation strategy that protects margin from both directions.
And because drawback refunds are calculated based on the duties you actually paid at entry, using First Sale can also impact the starting point for refund calculations—making the structure of your supply chain just as important as how you claim on the back end.
Why It’s Often Overlooked
The First Sale Rule has been on the books for decades, but it remains underutilized—largely because it requires cross-functional coordination. Procurement teams, legal departments, compliance officers, and logistics providers all need to be aligned. For many companies, it falls into the “too complicated” bucket, despite being a legitimate and often lucrative path to savings.
But for importers with stable sourcing relationships and the documentation to back it up, First Sale can be a quietly powerful tool. It doesn’t make headlines. But it does make a real difference.
