Frequently Asked Questions

Last updated: April 24, 2026

What is web accessibility compliance?

Web accessibility compliance is the practice of ensuring websites and digital services meet published standards so people with disabilities can perceive, navigate, and interact with them. The primary standard is WCAG 2.2, published by the W3C. Compliance is evaluated against specific success criteria at Level A, AA, or AAA. Public guidance from ADA.gov and the W3C defines the applicable requirements.

What is WCAG?

WCAG stands for Web Content Accessibility Guidelines, published by the World Wide Web Consortium (W3C). The current version is WCAG 2.2, released in October 2023. It defines testable success criteria organized under four principles: perceivable, operable, understandable, and robust. Level AA conformance is the most commonly referenced benchmark in legislation and procurement requirements.

What is ADA Title III?

ADA Title III is the section of the Americans with Disabilities Act that prohibits discrimination on the basis of disability in places of public accommodation. Federal courts have increasingly held that commercial websites qualify as places of public accommodation. ADA.gov provides public guidance on web accessibility obligations. Consult a licensed attorney for specific legal applicability.

What is the CBP refund portal?

The CBP refund portal refers to U.S. Customs and Border Protection resources for importers who overpaid duties. CBP administers drawback programs under 19 USC 1313, which allow recovery of certain duties paid on imported goods that are subsequently exported or destroyed. Eligibility depends on specific circumstances. Consult a licensed customs broker for drawback filings.

What is CUSMA?

CUSMA is the Canada-United States-Mexico Agreement, also known as USMCA in the United States and T-MEC in Mexico. It replaced NAFTA and entered into force on July 1, 2020. The agreement covers tariff preferences, rules of origin, digital trade, labor, and environmental provisions. Article 34.7 requires a mandatory joint review within six years of entry into force.

What is HTS classification?

HTS classification is the process of assigning Harmonized Tariff Schedule codes to imported goods to determine applicable duty rates. The HTSUS is maintained by the U.S. International Trade Commission (USITC) and administered by CBP. Each 10-digit HTS code maps to a specific duty rate, trade agreement eligibility, and regulatory requirement. Correct classification is the legal responsibility of the importer of record.

What is payment iframe accessibility?

Payment iframe accessibility refers to the degree to which embedded payment forms conform to WCAG 2.2 success criteria. Payment iframes present unique testing challenges because cross-origin security prevents parent-page scripts from inspecting iframe content. Key criteria include keyboard operability (2.1.1), name/role/value (4.1.2), error identification (3.3.1), and focus visibility (2.4.7).

Is my checkout WCAG compliant?

WCAG compliance of a checkout flow depends on conformance to specific success criteria across all components, including payment iframes, form fields, error messages, and navigation elements. Automated scanning can detect many common violations, but full conformance assessment may require manual testing with assistive technologies. A free scan can surface accessibility signals in your checkout.

What is agentic commerce readiness?

Agentic commerce readiness measures whether a checkout surface can be navigated and completed by autonomous AI shopping agents. Public records from Shopify, Google, and OpenAI indicate that AI agents interact with checkout flows using the same interfaces as screen readers: DOM parsing, ARIA attributes, and keyboard navigation. Checkouts that pass WCAG 2.2 criteria are generally more agent-readable.

Who determines compliance?

Compliance determinations are made by regulatory authorities, courts, and qualified professionals licensed in the relevant jurisdiction.

SmarterTariff surfaces signals; it does not make compliance determinations.

What should I do with scan results?

Scan results identify potential compliance signals and areas for review. They are not compliance certifications. Use results as a starting point for discussion with qualified professionals: a web accessibility consultant for WCAG findings, a licensed customs broker for tariff signals, or legal counsel for regulatory questions. Remediation decisions should involve professional guidance.
