HS Code Finder

Product description → suggested HS code(s) with explanation. AI-assisted.

What this tool does

The HS Code Finder takes your product description, material composition, and intended use, then returns two to three candidate Harmonized System codes at the six-digit level. Each suggestion includes a confidence indicator and a brief explanation of why that heading may apply. The tool cross-references the World Customs Organization's official HS nomenclature and patterns from publicly available binding tariff rulings.

This is not a binding classification. Customs authorities in each country have sole authority to determine the correct tariff heading for your goods. The tool helps you narrow down candidates before you consult a licensed customs broker or file for an advance ruling.

Who should use it

Import coordinators, purchasing managers, and logistics leads benefit most when onboarding new SKUs or validating supplier-provided codes. If you are sourcing a product you have never imported before, run it through the finder to get a starting point for duty estimation and compliance review. Customs brokers can use the output as a sanity check before submitting formal classification requests.

Inputs

  • Product description: A plain-language phrase describing the good, for example "stainless steel insulated water bottle" or "lithium-ion battery pack for electric bicycle." More detail improves accuracy.
  • Primary material: The dominant substance by weight or value, such as "18/8 stainless steel," "100% cotton woven fabric," or "polycarbonate plastic." Select from common options or enter a custom value.
  • Secondary material (optional): If the product is composite, list the next most significant material, for example "silicone gasket" or "aluminum heat sink."
  • Intended use: Describe the end function: "personal hydration," "industrial lubricant additive," "replacement automotive part." HS classification often hinges on use rather than composition.
  • Country of import: Two-letter ISO code (US, DE, IN, etc.). National tariff schedules extend HS codes beyond six digits, so your country context helps filter results.

Assumptions

The tool assumes your product description is accurate and complete. Omitting key details, such as whether a textile is woven versus knitted, can shift the classification by several chapters. It also assumes the product is in its finished or semi-finished state as imported; parts, accessories, and unassembled kits follow different classification rules under GRI 2(a).

Confidence scores are derived from pattern matching against historical binding rulings. A "high confidence" result means multiple rulings for similar products landed in the same heading. "Medium" or "low" confidence indicates fewer precedents or split rulings across headings.

Limitations

The finder does not account for preferential trade agreements, anti-dumping duties, or product-specific quotas. It does not verify country-of-origin rules that might affect duty rates under FTAs. Dual-use goods, items subject to export controls, or products requiring additional agency clearances (FDA, EPA, FCC) are flagged but not comprehensively screened.

You should not rely on this tool as legal advice or as a substitute for an advance ruling. For shipments above $2,500 in value or products you plan to import repeatedly, Reevol recommends filing a formal ruling request with your destination customs authority.

How results are calculated

The tool parses your inputs against the WCO HS nomenclature hierarchy, starting at the two-digit chapter level and drilling down through four-digit headings to six-digit subheadings. It applies the General Rules of Interpretation in sequence: GRI 1 (terms of headings and section/chapter notes), GRI 3(a) for goods classifiable under two or more headings, and GRI 6 for subheading comparison.

Material and use data are matched against a curated index of publicly released Binding Tariff Information decisions from the EU EBTI database and US Customs Rulings Online Search System. When multiple rulings agree on a heading, confidence rises. When rulings diverge, the tool surfaces alternatives and explains the distinguishing factors.

The output includes the six-digit HS code, the official heading text, a confidence label (high, medium, low), and a one-sentence rationale citing the relevant section note or ruling pattern. You can expand each result to see example rulings that informed the suggestion.

Disclaimer

This tool provides indicative HS code suggestions for informational purposes only. It does not constitute legal, tax, or customs advice. Tariff classification is the sole responsibility of the importer of record and the relevant customs authority. For high-volume or high-value imports, file an advance ruling request with your destination country's customs agency or consult a licensed customs broker before making procurement or pricing decisions.
