EDITORIAL GOVERNANCE & METHODOLOGY

Editorial Policy & Data Integrity Standards

✔ Published Standard (July 2026)

Customs tariff classification and duty assessment carry direct financial and legal implications for international traders. hscodedb.com operates under rigorous editorial standards designed to ensure zero data fabrication, strict primary-source citation, and complete transparency.

1. Sourcing & Verification Principles

Primary Sources Only: All 6-digit Harmonized System subheadings, 8/10-digit national tariff lines, and MFN duty rates are ingested directly from official government publications (USITC, HMRC, European Commission, WCO).
No Fabricated Duty Rates: Where official duty rate data for a specific national tariff line is unverified or unavailable, our system explicitly consolidates records to the verified parent level or marks data as "Coverage in progress" — never fabricating rates or guessing percentages.
Transparent Date Stamping: Every duty rate figure and trade remedy overlay carries a visible vintage date-stamp (e.g., "Verified July 2026") and links to the underlying official government source portal.

2. Transparent Omission Policy

We maintain an honest-omission policy across all 53 indexed countries. If a country's national tariff extension has not been fully audited against primary customs publications, we disclose the verification status clearly rather than serving generic templated placeholders.

3. Data Correction & Inquiry Process

We welcome feedback and data inquiries from customs brokers, trade attorneys, importers, and logistics professionals. If you identify a discrepancy or update in a tariff line, duty rate, or ruling citation:

Submit Data Correction / Inquiry: Email our editorial data team at [email protected] with the target HS code, country schedule, official source reference, and relevant Federal Register or customs bulletin notice. Inquiries are audited within 24 business hours.
