How it works

From store connection to fully classified catalog in minutes.

01

Connect your store

Install from the Shopify App Store. Atlanto reads your product catalog automatically.

02

We classify everything

AI analyzes each product against 500K+ CBP rulings and the full HTS schedule, applying General Rules of Interpretation.

03

Review with confidence

See every code with the legal reasoning behind it. Accept, flag for review, or export.

Other tools give you a code.
We give you the case.

Every classification comes with the legal reasoning, GRI rules applied, cited rulings, and rejected alternatives.

  "confidence": 0.92,
  "reasoning": "Classified under heading 8518 per GRI 1.
    Chapter 85 Note 3 defines headphones/earphones
    as articles designed to be held against the ear.",
  "gri_applied": "GRI 1",
  "similar_rulings": ["N301234", "N298776"],
  "alternatives_rejected": [

      "reason": "8517 covers communication apparatus,

    }
  ]
}

Customs shouldn't be a guessing game.

Sound familiar?

“Shopify auto-classified my products and now I'm paying tariffs I shouldn't be.”
“I got a customs hold and couldn't explain why my code was correct.”
“I'm spending hours per SKU manually looking up HS codes.”
“My 3PL assigned codes that don't match what CBP expects.”
