Eight providers, the criteria that actually separate them, and what each one is genuinely best for — including the situations where the right answer is not us.
Aduaria is one of the providers on this page. A ranked list published by a participant is marketing wearing the costume of research — whoever writes it wins, and every reader knows it.
So this page does the opposite: it states the evaluation criteria first, then describes what each provider is best suited for, including several situations where a competitor is plainly the better choice. Apply the criteria to your own situation and the shortlist follows. If you would rather not take a vendor's word for any of it, that is the correct instinct — start with the arithmetic instead.
Feature lists all look alike. These six criteria are the ones that change the outcome of a claim, and they are the questions worth putting to every provider here — us included.
| Provider | Type | Pricing model | Best for |
|---|---|---|---|
| Charter Brokerage | Full-service broker | Managed / contingency | The largest and most complex filers |
| Comstock & Holt | Full-service broker | Managed / contingency | Long-established drawback specialism |
| J.M. Rodgers | Full-service broker | Managed / contingency | Drawback alongside wider brokerage |
| Descartes | Enterprise suite | Subscription | Existing Descartes customers |
| Thomson Reuters ONESOURCE | Enterprise suite | Licence | Global trade managed in one suite |
| Pax AI | AI-native recovery | Contingency | Breadth across post-entry recovery |
| Caspian | AI-native recovery | Contingency | Integration depth and cash timing |
| Zollback | AI-native recovery | Contingency | Smaller importers and no minimums |
| Aduaria | Clearance-native | Contingency for drawback | Clearance and drawback on one dataset |

The traditional model: a firm files on your behalf, with staff assigned to your account. Decades of accumulated filing history, and the depth to handle unusual rulings.
Describes itself as the largest US drawback provider by recovery value, citing more than $4.1 billion recovered for clients since TFTEA took effect. Oriented to Fortune 500 and large-enterprise programmes. If your claim involves unusual manufacturing rulings, this depth of specific filing history is something no recent entrant — Aduaria included — can offer.
Both are long-running US drawback practices that appear consistently in industry comparisons. J.M. Rodgers pairs drawback with wider customs brokerage, which suits importers who prefer a single firm across clearance and recovery.
Drawback as one module inside a wider global-trade platform. Rarely the best standalone drawback tool; frequently the right answer anyway if you already run the suite.
Both offer drawback within broad global-trade platforms covering classification, filing and compliance, priced by subscription or licence rather than by recovery. If your classification and filing already live there, adding the drawback module usually beats introducing a second system and a second data pipeline. If you are not already a customer, buying an enterprise suite to access drawback is rarely proportionate.
Recent, well-funded entrants that connect to the records your existing broker and systems already produce, then mine them for refunds. The appeal is low friction: nothing about how you clear goods has to change.
Positions itself as an AI-native trade control tower spanning duty drawback, IEEPA tariff recovery, customs audits, FTZ, reconciliation and post-entry compliance. Founded in 2024 by a team from MIT, Google and Amazon, with $4.5M in seed funding led by Initialized Capital, and operates as a licensed customs brokerage that is ABI-certified with CBP. If your post-entry problem is wider than drawback, that breadth is a genuine advantage over a drawback-only tool.
A San Francisco ABI software vendor and licensed customs broker. Advertises line-item AI matching that accounts for substitution rules and TFTEA timeframes, more than 80 pre-built integrations across ERP, broker, inventory and logistics systems, and a refund-advance product that pays the recovery upfront and collects from CBP afterwards. Aduaria has no equivalent to that advance — if cash timing is your binding constraint, that difference is decisive and you should talk to them.
Built for the SMB and mid-market segment, roughly $5M to $500M in revenue, with in-house licensed brokerage. States it applies no minimum claim size, against legacy providers that have often required around $100K in annual refund potential — the single most common reason smaller importers have never been offered drawback at all. If you have been told your claim is too small to be worth filing, this is a reasonable place to test that.
The distinction from the category above is where the data comes from, not how modern the software is.
Aduaria files your entries, so the classification and duty data underneath a drawback claim is data it produced and verified at the time of clearance rather than inherited afterwards. Because classification is the load-bearing step in substitution matching, that provenance is the factor most likely to affect claim quality — and eligibility surfaces continuously as entries clear, instead of during a periodic look-back. A licensed customs broker reviews and signs every entry and every claim. Drawback pricing is contingency: no upfront fee, a share of what is recovered.
The honest limitation: this only applies if you are willing to move clearance. If you are happy with your current broker and simply want the refund, a recovery specialist above fits your situation better than we do. Aduaria is also a newer entrant, without the decades of filing history the established brokers can point to.
Everything above comes from each provider's own public materials, and vendor claims are reproduced as claims. We have not audited anyone's recovery totals, refund timelines, or accuracy rates — including our own, which is why you will not find a success-rate or speed comparison on this page. Several providers advertise compressed refund timelines; those describe their own preparation speed, since CBP's payment step is outside any vendor's control and depends mostly on whether Accelerated Payment is approved.
Providers are grouped and described, not scored, and the order within each group is not a ranking. This page is reviewed periodically; the date under the title is when it was last checked.

There is no single best option, because the providers are built for genuinely different situations. Very large filers with complex manufacturing rulings are best served by established full-service brokers such as Charter Brokerage. Companies already running an enterprise trade suite usually do best adding that suite's drawback module. Importers who want to keep their current broker are best served by an AI-native recovery specialist such as Pax AI, Caspian or Zollback. Importers who want clearance and drawback on the same verified data are the case Aduaria is built for. Decide by matching your situation to those categories rather than by a ranked list.
Because Aduaria is one of the providers listed, and a ranking published by a participant is not a neutral ranking. Instead the evaluation criteria are stated first and each provider is described by the situation it fits best, including the cases where a competitor is the better choice. Readers can apply the criteria to their own situation rather than trusting our ordering.
Two models dominate. Contingency pricing takes a share of the duty actually recovered, so there is nothing to pay if no refund arrives — common among the AI-native providers and many full-service brokers. Subscription or licence pricing charges an annual fee regardless of recovery, typical of enterprise trade suites. Some legacy providers have historically applied minimum claim sizes, which is why smaller importers were often turned away.
Yes. A drawback claim is a customs entry, so a licensed customs broker signs it. Several of the AI-native providers, including Pax AI, Caspian, Zollback and Aduaria, hold or work with licensed brokerage capability themselves rather than requiring you to bring your own.
It depends on privileges rather than vendor marketing. With Accelerated Payment approved, refunds are typically paid within weeks of filing; without it, the claim waits for CBP liquidation, which commonly takes a year or more. Several providers advertise compressed timelines — treat those as claims about their own preparation speed, and confirm what is being measured, since CBP's payment step is not under any vendor's control.
Whichever provider you choose, the first useful step is the same: find out roughly what you are owed. Run it on your own figures in under a minute — no email, no call.
