Key Takeaways
You're paying import duties on every shipment. Your CFO just found out you can get most of that money back — and now wants you to "make the dive 5 years in the past" to recover it all. So you dig in, and quickly realize why most companies never bother: the documentation is scattered across a dozen systems, your freight forwarder takes weeks to respond, and "everything falls apart on the export side," as one broker noted in a recent trade compliance thread.
Duty drawback — the U.S. government program that refunds up to 99% of import duties when goods are re-exported, used in manufacturing for export, or destroyed — is one of the most valuable and least-used tools in international trade. According to data cited on Zollback's YC company page, an estimated ~$15 billion in eligible tariff refunds go unclaimed every year. That's not because companies don't qualify. It's because the process has historically been too slow, too manual, and too complex to be worth the effort for most businesses.
This guide explains how duty drawback works, what you need to file a claim, and how modern automation has compressed the timeline from 9–12 months down to 10–15 working days.
Duty drawback is a refund of customs duties, internal revenue taxes, and certain fees paid on imported goods that are subsequently exported, used in U.S. manufacturing for export, or destroyed. It's authorized under 19 U.S.C. § 1313 and governed by 19 CFR Part 190. The program has existed in some form since 1789 — it's not new. What's new is the scale of the opportunity, especially with Section 301 tariffs on Chinese imports and reciprocal tariffs expanding the duty burden on importers.
So why does ~80% of eligible refund potential go unclaimed? The same reasons trade professionals consistently identify:
The result: billions in legitimately owed refunds sit uncollected while importers absorb the duty costs as a permanent line item on their P&L.
Before filing anything, you need to determine which drawback type applies to your situation. There are three under U.S. law, as CBP outlines:
This applies when imported goods are used as inputs in a U.S. manufacturing process and the finished product is then exported. A classic example: importing steel components and exporting finished machinery.
Manufacturing drawback is often the most valuable type — but also the most complex to file. The Harmonized Tariff Schedule (HTS) classification of the finished export can differ from the imported input, which requires careful matching. You'll also need to establish a manufacturing drawback ruling with CBP that defines the relationship between your imported inputs and exported outputs.
One important expansion under the Trade Facilitation and Trade Enforcement Act (TFTEA): substitution rules now allow you to claim drawback using commercially interchangeable merchandise — not just the exact imported goods. This significantly broadens who qualifies.
This covers imported goods that are exported in the same condition as imported, without being used in the U.S. Retailers and distributors who import merchandise and re-export unsold inventory to Canada, Mexico, or Europe are typical candidates. If you're rebalancing inventory across borders, you're likely eligible.
This applies to imported goods that don't conform to specifications, were shipped without the consignee's consent, or are returned by customers and subsequently destroyed. For e-commerce companies with high return volumes, this is often an overlooked refund source.
Ordinary customs duties — including Section 301 tariffs on Chinese imports — are eligible for drawback. Merchandise Processing Fees (MPF) and Harbor Maintenance Fees (HMF) are also recoverable in many cases. Antidumping and countervailing duties, as well as Section 232 duties, are generally not eligible — consult CBP guidance or a licensed customs broker to confirm the rules for your specific goods.
One important timing note: claims must generally be filed within the statutory time limits — typically 5 years from the date of importation and 3 years from the date of export, though specific rules vary by drawback type. If your CFO wants to recover duties from previous years, you likely can — but start the clock now.

The reason most eligible companies never file isn't that they don't qualify. It's that the traditional drawback process is painful enough to make the refund feel not worth it.
Here's how the two approaches actually compare:
The difference isn't incremental. It's a 95%+ reduction in processing time and a meaningfully larger refund check.
Here's a practical walkthrough of the modern drawback filing process — from document chaos to cash in your account.
Collect your core import and export records. You don't need them perfectly formatted — just gathered:
If you sell ex works and the buyer's freight forwarder controls the export leg, this is where most programs stall. As one broker shared, "trying to chase them down to get export docs and ITNs is nothing short of a nightmare." The practical fix: start demanding documentation from your customer's forwarder proactively, before you need it for drawback. Build it into your standard contract terms.
Before organizing years of records, confirm you actually qualify and get a realistic estimate of your refund potential. A free assessment takes the guesswork out of whether the effort is worth it.
Our free eligibility assessment screens your trade profile automatically and estimates your potential refund across all three drawback types — no commitment required.
Upload your raw files to a secure, certified platform. The AI parses and structures the data automatically — no manual formatting, no spreadsheet cleanup. This step alone eliminates the most time-consuming part of the traditional process.
The optimization engine evaluates every possible import-export matching combination under the applicable regulatory constraints and produces the package that maximizes your refund. An in-house licensed customs broker then verifies the claim for compliance before it goes anywhere near CBP.
Once the claim clears compliance review, it's electronically filed with CBP via certified ABI software. You track status through the platform until the refund is deposited.
Most companies treat drawback as a one-time project. That's leaving money on the table. Continuous monitoring identifies new eligible transactions as they occur and files claims automatically — turning tariff recovery from an annual scramble into a steady cash flow stream.

Duty drawback doesn't require a perfect documentation system, a dedicated compliance team, or a six-figure annual refund minimum. It requires the right process — one that can handle messy real-world trade data and find the refund that's already sitting in your import history.
The core insight from practitioners who've tried and failed at drawback is consistent: the programs that fail do so because of process gaps, not eligibility gaps. Most companies that don't claim drawback qualify for it — they just never had a fast, accessible way to pursue it.
We built Zollback to fix that. As both a technology platform and a licensed customs brokerage, we combine AI-powered document parsing, algorithmic refund optimization, and direct CBP filing authority into a single end-to-end service. Our optimization engine has recovered 15–20% more in refunds than traditional providers in head-to-head comparisons — and our in-house team includes licensed customs brokers who verify every claim before it's submitted.
Pricing is purely performance-based: no retainers, no setup fees, no upfront costs. We only get paid when you do — on a tiered model where the percentage decreases as your total refund value increases.
If you're paying import duties and exporting goods, destroying returned inventory, or re-exporting unsold merchandise, there's a good chance you have unclaimed refunds sitting in your trade history right now. A free eligibility check takes minutes and will show you what's recoverable — with no obligation to move forward.
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, turning a cost center into a source of cash flow. We help companies navigate this process.
Any company that imports goods into the U.S. and later exports them, uses them in manufacturing for export, or destroys them may be eligible. This includes manufacturers, distributors, and e-commerce retailers. A free eligibility assessment can confirm if your specific trade profile qualifies.
An estimated $15 billion in drawback goes unclaimed annually primarily due to process complexity. Traditional methods are manual, slow (9-12 months), and require extensive documentation gathering, which most companies find too burdensome. Modern automated platforms solve this by simplifying the entire process.
The timeline depends on the filing method. Traditional drawback providers typically take 9–12 months to secure a refund. With our automated platform, the claim preparation process is compressed to just 10–15 working days, significantly accelerating your cash recovery.
Most ordinary customs duties, including Section 301 tariffs, are eligible for drawback. Merchandise Processing Fees (MPF) and Harbor Maintenance Fees (HMF) may also be recoverable. However, antidumping, countervailing, and Section 232 duties are generally not eligible.
You can typically file drawback claims for up to five years from the date of import, provided the export or destruction occurred within the statutory time limits. This allows companies to recover significant funds from prior years, but it's important to act before the eligibility window closes.
Incomplete export documentation is a common challenge that stops many companies from filing. Our platform can often work with partial data, and our team of licensed customs brokers can guide you on strategies to retrieve missing documents, such as Internal Transaction Numbers (ITNs), from your partners.
We operate on a performance-based model with no upfront costs, setup fees, or retainers. We only get paid a percentage of the refund we successfully recover for you. The fee percentage decreases as your total refund amount increases, ensuring our incentives are aligned with yours.
