Frequently Asked Questions
How is this different from ChatGPT or other AI tools? +
General AI tools frequently hallucinate ruling numbers that don't exist. Harmonize.ai only cites real, verifiable CBP CROSS rulings — every citation links to the actual source document. We also show multiple classification candidates with confidence scores so you know when to escalate.
What does a classification output look like? +
Each classification returns up to 5 candidate HTS codes, each with a confidence score, applicable GRI reasoning, cited CBP ruling numbers with direct links, and a recommended action (proceed vs. escalate). You also get a downloadable PDF research memo. See a sample output above ↑
Does this replace a licensed customs broker? +
No. Harmonize.ai is a classification research platform, not a customs broker or legal advisor. It supports faster research and documentation workflows that professionals can review before final filing decisions. Think of it as a research assistant, not a replacement for licensed expertise.
How accurate is it really? +
On the Flexify ATLAS benchmark (200 diverse SKUs), Harmonize.ai achieved 96.5% accuracy at the 10-digit HTS level. We publish our full methodology, known failure modes, and benchmark details on our accuracy methodology page. No cherry-picked results.
What if a product has multiple plausible HTS headings? +
That's exactly what Harmonize.ai is built for. It presents alternative classifications with rationale, confidence scoring, and relevant CBP ruling support for each. This helps trade teams apply GRI logic and document reasonable care research — critical for audit defense.
How much does it cost compared to a customs broker? +
Customs broker consultations typically run $75–500+ per hour for classification research. With Harmonize.ai, classifications start at $0.49 each on the Starter plan ($49/mo for 100 classifications) — that's significantly less expensive for routine research. Complex or high-risk classifications should still involve a licensed broker.
Do you have an API? +
Yes. Our REST API lets you integrate HTS classification research directly into your customs software, ERP, or compliance workflows. View API documentation →
Can I rely on one CBP ruling for every similar product? +
Not always. CBP rulings are fact-specific and can vary by composition, function, and product design. Harmonize.ai helps compare your product details to cited rulings so you can assess fit and escalation risk — that's why we show multiple candidates, not just one answer.
Can I classify products from photos? +
Yes! Our image classification feature uses GPT-4o vision to analyze product photos and extract tariff-relevant attributes like material composition, construction method, and functional features. Upload up to 3 images alongside your text description for enhanced accuracy. Available on Starter plans and above.
What is the Tariff Impact Simulator? +
The Tariff Impact Simulator lets you upload a CSV of your classified products and model how tariff changes would affect your total duties. Simulate scenarios like Section 301 removal (China 25%), Section 232 at 50% (steel/aluminum), Section 122 global tariffs, or USMCA preferential rates. You can also create custom scenarios.
What does 100% on the CBLE mean? +
The Customs Broker License Exam (CBLE) is the standardized test that customs brokers must pass to earn their federal license. Harmonize scored 100% on all 22 product classification questions from the April 2025 and October 2024 exams. This is the same benchmark that competitors like Gaia Dynamics and KYG Trade publish. See our full results on the CBLE Benchmark page.
