What is HTS classification?

HTS (Harmonized Tariff Schedule) classification is the process of assigning a 10-digit code to imported goods that determines their duty rate, regulatory requirements, and admissibility into the United States. Every product entering the US requires an HTS code, and 42% of CBP penalties stem from misclassification.

How does AI-powered tariff classification work?

AI-powered tariff classification uses machine learning to analyze product descriptions, cross-reference the full HTS schedule (6,500+ pages), search 200,000+ CBP binding rulings, and apply GRI (General Rules of Interpretation) classification rules. TariffLens reduces classification time from 30 minutes to 30 seconds while providing cited sources and audit-ready documentation.

What is reasonable care in customs compliance?

Reasonable care is the legal standard under 19 USC 1484 that requires importers and customs brokers to use reasonable care in classifying goods, determining duty rates, and providing accurate information to CBP. TariffLens helps demonstrate reasonable care by providing GRI reasoning, cited CBP rulings, and timestamped audit trails for every classification.

How can I prepare for a CBP focused assessment?

To prepare for a CBP focused assessment, you need documented evidence of reasonable care for every classification. This includes the GRI rule applied, supporting CBP binding rulings, alternative codes considered, and timestamped records. TariffLens automatically generates this documentation for every classification, building the audit trail CBP expects to see.

The short version

Zonos is a cross-border ecommerce platform. Its Classify product assigns HS/HTS codes (6 to 14 digits, defaulting to a 6-digit universal code, and up to a country-specific 10-digit code when a ship-to country is supplied) and its Landed Cost product calculates guaranteed duties, taxes, carrier, and brokerage fees at checkout for delivered-duty-paid (DDP) shipping across nearly 200 countries. That is a genuinely strong fit for online retailers selling internationally. TariffLens is purpose-built for the US importer and customs-broker job: every result is a full 10-digit HTSUS code with the GRI reasoning chain, cited CBP binding rulings from a 200,000+ corpus, and a real-time US duty calculation covering Section 301/201/232/122, IEEPA/reciprocal tariffs, UFLPA, and AD/CVD. Zonos does not cite CBP rulings, its classification defaults to 6-digit and is global rather than US-first, and its product pages do not document computation of the US special-tariff stack. If your job is checkout landed cost and cross-border DDP, Zonos is the better tool; if your job is defensible US classification and the true US duty bill, TariffLens is.

Choose Zonos for guaranteed cross-border landed cost and DDP at ecommerce checkout. Choose TariffLens when you need defensible US 10-digit HTS classification with cited CBP rulings and the full real-time 2026 US duty stack.

Side by side

TariffLens vs Zonos, line by line.

	TariffLens	Zonos
Primary job	Defensible US HTS classification and the true US duty bill for importers and customs brokers.	Cross-border ecommerce checkout: guaranteed landed cost and delivered-duty-paid (DDP) for online retailers.
10-digit US HTS code	Full 10-digit HTSUS code on every result.	Classify returns 6 to 14 digits; the default is a 6-digit universal HS code, with a country-specific code (typically 10 digits) only when a ship-to country is supplied. Global, not US-first.
CBP ruling citations	Inline citations from 200,000+ CBP binding rulings on every classification.	No CBP CROSS ruling citations. Not published on the Classify product or docs pages.
US duty stack (301/232/IEEPA/AD-CVD)	Real-time landed math covering Section 301/201/232/122, IEEPA/reciprocal tariffs, UFLPA, and AD/CVD, layered automatically per origin.	Landed Cost computes cross-border import duties, taxes, and carrier and brokerage fees with de minimis thresholds; its product pages do not document computation of the US Section 301/232/IEEPA/122 stack or AD/CVD. Zonos does maintain a current US tariff tracker as guidance.
Guaranteed landed cost / DDP at checkout	Not offered. TariffLens computes duty for classification and analysis, not a checkout DDP guarantee.	Guaranteed landed cost at checkout with DDP via DHL, FedEx, and UPS; Zonos pays the difference if customs or carriers charge more than quoted.
Multi-country coverage	US HTS only. Does not cover other national HS schedules.	Nearly 200 countries with 50+ languages.
Ecommerce platform integration	RESTful API and CSV bulk upload, self-serve.	Shopify Duty and Tax app plus prebuilt BigCommerce, Adobe Commerce, WooCommerce, and Miva plugins, and a GraphQL API.
Deployment	Self-serve, live in minutes, no sales call.	Self-serve dashboard plus platform plugins; most merchants live within days.
Pricing	Self-serve, sign up and start.	Landed Cost is publicly priced at $2 per order plus 10% of duties, taxes, and non-Zonos fees (plus a $5 cross-dock fee and an optional +10% extended guarantee); Classify and overall platform pricing are quote-based.

Where TariffLens wins

TariffLens is purpose-built for US HTS classification and tariff analysis. It reasons through the General Rules of Interpretation on every classification, grounded in the complete HTSUS and 200,000+ CBP binding rulings, and returns a defensible artifact: a 10-digit HTS code, the full GRI chain, cited rulings, alternatives considered, a confidence score, and the real-time US duty calculation for the origin country.

Full 10-digit US HTSUS code with GRI step-by-step reasoning on every result, purpose-built for US import classification rather than a global default of 6 digits.
200,000+ CBP binding rulings cited inline, so every classification is grounded in actual CBP precedent and defensible in a protest or CF-28.
Real-time US duty stack computed per origin: Section 301/201/232/122, IEEPA/reciprocal tariffs, UFLPA, and AD/CVD, layered automatically.
Self-serve with RESTful API, CSV bulk upload, and audit-ready exports, live in minutes with no sales call.
Confidence scoring routes high-confidence results to auto-accept and low-confidence items to human review.

Where Zonos wins

Zonos is a cross-border ecommerce platform for international sellers. Its Classify product uses AI to assign HS/HTS codes from a product name, description, or image, and its Landed Cost product calculates guaranteed duties, taxes, and carrier and brokerage fees at checkout so shoppers can pay delivered-duty-paid. It covers nearly 200 countries with 50+ languages and ships prebuilt plugins for BigCommerce, Adobe Commerce, Miva, and WooCommerce plus a Shopify Duty and Tax app and a GraphQL API. The buyer is primarily an online retailer selling internationally, not a US customs broker.

Guaranteed landed cost at checkout: if customs or carriers charge more than quoted, Zonos pays the difference, a checkout guarantee a US-classification tool does not offer.
True cross-border DDP with DHL, FedEx, and UPS, so shoppers prepay duties and taxes at checkout, a logistics and checkout job TariffLens does not do.
Deep ecommerce-platform distribution: a Shopify app plus BigCommerce, Adobe Commerce, WooCommerce, and Miva plugins, turnkey for online retailers.
Multi-country classification at scale across nearly 200 countries and 50+ languages, with image-based input and bulk CSV upload.
Genuinely current US tariff tracking in its public docs (a US Import Tariff Tracker covering the 2026 IEEPA-to-Section 122 transition, reciprocal tariffs, and the de minimis suspension).

Where it can fall short

Classification defaults to a 6-digit universal HS code; US 10-digit output is a byproduct of a global engine and appears only when a ship-to country is supplied, not a US-first classifier.
No CBP CROSS binding-ruling citations on results, so classifications are not grounded in the US precedent that survives a CF-28.
Its product pages do not document computation of the US special-tariff stack (Section 301/232/IEEPA/122) or AD/CVD as line items; the tariff tracker is guidance, not a stated calculation feature.
Optimized for ecommerce checkout and parcel DDP, not customs-broker workflows such as formal entry summaries and classification defensibility.
Core Classify and platform pricing is quote-based; only the Landed Cost per-order fee is publicly listed.

The differences that matter

What actually separates them.

Different jobs: checkout landed cost vs. defensible US classification

Zonos is built to show a shopper the full landed cost at checkout and guarantee it, then move the parcel DDP. TariffLens is built to give a US importer or broker a 10-digit HTS code they can defend to CBP, with the GRI reasoning and cited rulings that a CF-28 response requires, plus the real US duty bill across every 2026 measure. Both compute duty, but for different buyers and different moments: one at ecommerce checkout, the other at classification and entry.

6-digit default vs. US 10-digit by design

Zonos Classify returns a 6-digit universal HS code by default and only extends to a country-specific 10-digit code when you supply a ship-to country, because it is engineered for nearly 200 destinations. TariffLens always produces a full 10-digit HTSUS code, because the 10-digit statistical suffix is exactly what a US importer files and what determines the duty owed. If your workflow is US entries, the difference between a default 6-digit code and a purpose-built 10-digit result is the difference between a starting point and a filing.

Ruling citations: the clean, verified contrast

Every TariffLens classification cites the specific CBP binding rulings that bear on the decision, from a corpus of 200,000+. Zonos does not cite CBP CROSS rulings anywhere on its Classify product or documentation pages. For a buyer whose concern is defensibility rather than checkout speed, cited precedent is the difference between an opinion and a position you can stand behind in an audit.

Where Zonos genuinely wins

Zonos guarantees the landed cost it quotes at checkout and pays the difference if customs or carriers charge more, ships DDP with DHL, FedEx, and UPS, and integrates directly into Shopify, BigCommerce, Adobe Commerce, WooCommerce, and Miva. TariffLens does none of that: it is not a checkout or logistics product. If your problem is showing and guaranteeing landed cost to an international shopper, Zonos is the right tool and TariffLens is not.

Which should you choose?

Choose Zonos if…

You sell cross-border ecommerce and need guaranteed landed cost and DDP at checkout so shoppers prepay duties and taxes.
You need HS classification across nearly 200 countries, not just the US, ideally from images and bulk catalogs.
You want a turnkey Shopify, BigCommerce, Adobe Commerce, WooCommerce, or Miva integration rather than an API build.
Your priority is a shopper-facing checkout experience, not customs-broker classification defensibility.

Choose TariffLens if…

You need US HTS classification defensible in a CBP audit: GRI reasoning plus cited CBP binding rulings on every result.
You need the true US landed-duty math across the full stack: Section 301/201/232/122, IEEPA/reciprocal, UFLPA, and AD/CVD.
You want a purpose-built US 10-digit result rather than a global engine that defaults to 6 digits.
You are a customs broker, importer, or compliance team, not an ecommerce merchant optimizing checkout.

FAQ

TariffLens vs Zonos, answered.

Is TariffLens or Zonos better for US HTS classification?

For defensible US classification, TariffLens: it returns a full 10-digit HTSUS code with GRI reasoning and cited CBP binding rulings on every result. Zonos Classify can output a US 10-digit code when you supply a ship-to country, but it defaults to a 6-digit universal HS code, is built for nearly 200 countries rather than the US specifically, and does not cite CBP rulings. Zonos is the better tool when you need cross-border classification at ecommerce scale.

Does Zonos calculate US Section 301, 232, IEEPA, and AD/CVD tariffs?

Zonos Landed Cost computes cross-border import duties, taxes, and carrier and brokerage fees with de minimis thresholds, and Zonos maintains a public US Import Tariff Tracker that is current on the 2026 regime. However, its product pages do not document computation of the US special-tariff stack (Section 301/232/IEEPA/122) or AD/CVD as line items. TariffLens computes that full stack in real time, per origin.

How much does Zonos cost?

Zonos publishes Landed Cost pricing at $2 per order plus 10% of duties, taxes, and non-Zonos fees, with a $5 cross-dock fee and an optional extended guarantee at an additional 10% of duty and tax. Classify and overall platform pricing are quote-based. TariffLens is self-serve, with no sales call to get started.

Does Zonos cite CBP rulings?

No. Zonos does not cite CBP CROSS binding rulings on its Classify product or documentation pages. TariffLens cites specific CBP binding rulings from a corpus of 200,000+ on every classification.

Is TariffLens a good Zonos alternative?

It depends on the job. If you need defensible US 10-digit classification and the true US duty bill, TariffLens is the better fit: cited rulings, GRI reasoning, and the full 2026 US stack, self-serve with API. If you need guaranteed landed cost and DDP at ecommerce checkout across many countries, Zonos is the better fit and TariffLens does not replace it. Many teams would use TariffLens for compliance-grade classification and a checkout tool like Zonos for the shopper experience.
