Four real tools touching some part of Section 232 or broader tariff compliance, from a free, dated exposure checker to enterprise-quoted global trade-management platforms. On 2026-08-06, the Bureau of Industry and Security published Federal Register notice 2026-15961 proposing 14 additional derivative steel and aluminum articles under Section 232, with public comment open through 2026-08-27. That dated, narrow event is a different problem from general HS/HTS classification, and confusing the two is the most common mistake we see importers make when evaluating tools in this space.
TariffWatch checks whether a specific HTS code falls inside the proposed derivative-article expansion in notice 2026-15961, layered on top of the existing Section 232 tariff structure — annex-based rates on full customs value (50% Annex I-A, 25% Annex I-B and I-C, a 15% all-in rate for Annex III), per Proclamation 11032 of 2026-06-01. It is free, dated to this specific comment window, and does not attempt general HS/HTS classification across unrelated product categories.
The operating company's site is gaiadynamics.ai, checked September 14, 2026, titled "AI-Powered Global Trade Compliance Platform & Software | Gaia." (gaiadynamics.com currently resolves to a GoDaddy domain-for-sale listing.) Its public pricing page, checked the same day, lists five tiers, all billed yearly: Free $0/mo with 30 credits per year, Starter $99/mo, Pro $379/mo, Advanced $1,399/mo, and Enterprise at custom pricing. Its positioning is general classification across product categories, not a tool built around the Aug 27, 2026 comment window specifically. See our full TariffWatch vs Gaia Dynamics breakdown.
Descartes' own Customs and Regulatory Compliance page, checked September 14, 2026, covers Customs Declarations, Security Filings, Product Classification & Duty Determination, Denied Party Screening, Other Government/Industry Programs, and Foreign Trade Zone Management — an ongoing platform rather than a checker built around one dated regulatory event. Descartes publishes no self-serve price on that page. See our full TariffWatch vs Descartes CustomsInfo breakdown.
Two additional global trade-management platforms worth naming. E2open's global-trade product page is at e2open.com/global-trade/. Thomson Reuters describes ONESOURCE Global Trade Management on its own page (tax.thomsonreuters.com/en/onesource/global-trade-management, checked September 14, 2026) as "Global trade management — Lower supply chain risk and increase efficiency," with modules for Global Duty Optimization, Free-Trade Agreement Management, Foreign-Trade Zone Management, Denied Party Screening, Supply Chain Compliance, Global Classification powered by CoCounsel, and Export/Connectivity. Thomson Reuters publishes no self-serve pricing on that page, and it does not name Section 232 derivative-article coverage specifically.
If your immediate question is narrow and dated — does my specific HTS code fall inside the proposed Section 232 derivative-article expansion closing for comment 2026-08-27— a free, purpose-built checker answers that directly without an enterprise sales process. If your need is ongoing, broad HS/HTS classification and trade content across many product categories and countries, a platform like Gaia Dynamics, Descartes CustomsInfo, E2open, or ONESOURCE is solving a larger, different-shaped problem, and is priced accordingly.
This is a hypothetical scenario, not a real customer case. Picture an importer running an enterprise global trade-management platform for ongoing HS/HTS classification across hundreds of SKUs. The platform correctly classifies every product. Separately, nobody has specifically checked whether any of those classifications now fall inside the newly proposed Section 232 derivative-article expansion, because that is a dated, narrow regulatory event layered on top of general classification, not something a broad platform is necessarily built to flag proactively (that comment window closed Aug 27, 2026).
Section 232, codified at 19 U.S.C. § 1862, is one of several distinct U.S. trade-remedy authorities an importer might need to track simultaneously. USTR's Section 301 program operates on a completely separate legal basis (unfair trade practices rather than national security) and a separate rulemaking timeline from BIS's Section 232 docket. None of the four tools above track both authorities with equal specificity: general classification platforms (Gaia Dynamics, Descartes CustomsInfo, E2open, ONESOURCE) typically surface whichever trade-remedy tariffs apply to a classified product across authorities, while TariffWatch is deliberately narrow, built around this specific Section 232 derivative-article proposal rather than trade-remedy tracking generally.
It is worth stating plainly, across every tool on this list including TariffWatch: none of them are a substitute for a binding CBP ruling or a licensed customs broker's classification determination on a genuinely ambiguous product. The docket for the current Section 232 derivative-article proposal, at regulations.gov, is the authoritative record of the proposed rule itself; any tool's interpretation of how a product maps onto that proposal is a starting point for further verification, not a final legal determination. For a product whose classification or Section 232 exposure is genuinely unclear, a formal CBP ruling request remains the definitive path, regardless of which software tool an importer uses to triage the question first.
The pricing pattern across these tools follows their scope. TariffWatch, narrow and dated to one regulatory event, is free. Gaia Dynamics publishes five tiers (Free $0, Starter $99, Pro $379, Advanced $1,399 per month billed yearly, plus custom Enterprise). Descartes and Thomson Reuters publish no self-serve price on the product pages we checked on September 14, 2026. That is what those pages show; we do not estimate what any of them charges.
The right choice depends on how often you need to answer this kind of question and how broad your product catalog is. An importer with a handful of HTS codes and one immediate, dated question ("does my product fall inside the proposed derivative-article expansion") is well served by a free, narrow checker. An importer managing thousands of SKUs across dozens of countries, needing ongoing classification and trade-content updates as global tariff schedules shift, has a genuinely larger, different-shaped problem that justifies an enterprise platform's cost and implementation effort. Neither approach is universally correct; the fit depends on the actual scale and frequency of the underlying need.
A practical way to sequence these tools: start with TariffWatch's free exposure check against your actual product catalog for this specific proposal. If none of your HTS codes fall inside the proposed derivative-article expansion, you have your answer at zero cost and no further action is needed for this comment window specifically. If your catalog does show exposure, or if you discover during that check that your classification data itself is uncertain across a broad set of products, that is the signal to evaluate an ongoing classification platform like Gaia Dynamics, Descartes CustomsInfo, E2open, or ONESOURCE, because the underlying problem has grown from "one dated question" to "ongoing classification confidence across my catalog."
It is worth being concrete about the stakes. The existing Section 232 tariff structure applies annex-based rates on full customs value (50% Annex I-A, 25% Annex I-B and I-C, a 15% all-in rate for Annex III), per Proclamation 11032 of 2026-06-01. A product newly captured by the proposed derivative-article expansion in notice 2026-15961 would move from whatever its prior tariff treatment was to the proposed rate for that article (25% for most, 15% for agricultural trailers, the mobile-equipment rates for cranes and lifting frames, 50% on container value for filled steel containers), a materially large swing in landed cost for any affected importer. None of the four tools on this list can change that outcome once the rule is finalized; what they can do, at very different price points, is help an importer identify exposure early enough to plan around it, whether that means submitting a comment during the open window, sourcing differently, or simply budgeting for the new rate.
A pattern worth watching for across this category: a platform marketing itself broadly as "trade compliance software" may or may not proactively flag a newly proposed Section 232 derivative-article expansion the moment it publishes, depending on how its content-update pipeline is built and how quickly it ingests new Federal Register notices. Reading each vendor's actual documented update cadence and scope, rather than assuming broad marketing language covers every dated regulatory event automatically, is the more reliable way to determine fit, particularly during an active comment window like the one closing 2026-08-27.
These four tools sit at genuinely different points on the scope spectrum, from a free, one-purpose, dated checker to enterprise-quoted global trade-management platforms. TariffWatch answers one narrow question about one proposed rule at zero cost. Gaia Dynamics offers a mid-tier, published-price five published subscription tiers for broader classification. Descartes, E2open, and ONESOURCE publish no self-serve price. None of the four is universally "best"; the right one depends entirely on whether your actual need is this one comment window or an ongoing trade- compliance program.
One last practical note: the specific comment window this page centers on closes 2026-08-27, and Federal Register proposals of this kind are frequently amended or extended before finalization. Re-check the docket directly at regulations.gov and the notice itself before relying on any single snapshot, including this one, as the final word on which HTS codes end up covered.
None of the vendors named on this page paid for placement, and none reviewed this page before publication. Every price, product description, and live-check date above is independently sourced from each company's own public site or the Federal Register itself, checked directly by us on the date noted next to it.
Regardless of which tool you eventually rely on for ongoing classification work, the fastest way to answer today's specific question, whether a given HTS code falls inside the proposed derivative- article expansion, is to read the notice itself alongside your own product's classification records. The Federal Register text lists the specific HTSUS subheadings under consideration; cross-referencing that list against your own catalog takes minutes for a small product line and considerably longer for a large one, which is exactly the gap a purpose-built checker like TariffWatch exists to close.
Among the tools we checked, TariffWatch is the only one built specifically around the proposed derivative steel/aluminum articles in Federal Register notice 2026-15961, published Aug 6, 2026, and its public comment window closing 2026-08-27. The others below offer broader, general trade-classification or global-trade-management capability that is not dated to this specific regulatory event.
Because both categories get searched under similar terms ("Section 232 tools," "tariff compliance software") even though they solve different-scoped problems. We separate them explicitly rather than ranking a quote-only enterprise platform against a free, narrow checker as if they compete head-to-head.
No. Pricing below ranges from free (TariffWatch), to no published self-serve price (Descartes, E2open, ONESOURCE), to a published five-tier structure (Gaia Dynamics: Free $0, Starter $99, Pro $379, Advanced $1,399 per month billed yearly, plus custom Enterprise). The right fit depends on whether you need one dated, narrow answer or an ongoing global trade-classification platform.
TariffWatch is a data and workflow tool that estimates Section 232 tariff exposure from publicly available Federal Register, USITC, and CBP data. TariffWatch is NOT a licensed customs broker under 19 CFR 111, NOT a filer of record, and NOT a legal-advice service. This is not customs classification advice. Compliance decisions remain the responsibility of the importer and their customs broker or trade attorney. TariffWatch does not guarantee that any classification, exposure estimate, or comment letter will be accepted by CBP, BIS, or Commerce.
