Data Integrity & Methodology

Calculated for Accuracy,
Verified by Authorities.

Every digit on SSLT Global is traceable to a specific regulatory instrument. We don't use AI-generated guesses for tariff rates; we use live and versioned official schedules.

Named Instruments

Calculations are keyed to specific Notifications (India), Federal Register Notices (US), or Official Journal entries (EU).

Conservative Logic

Where interpretation is required, our engines default to the highest applicable rate or most stringent compliance requirement.

Human Verification

While feeds are automated, the calculation logic is peer-reviewed by trade compliance experts against source texts every quarter.

Regional Calculation Methodology

India (GST & Customs)

Calculated using the 8-digit HSN classification system. GST is applied on a transaction value basis plus basic customs duty (BCD) and social welfare surcharge (SWS) where applicable, following the IGST Act 2017.

United States (HTS & Section 301)

Utilizes the 10-digit HTSUSA schedule. Our stack includes MFN rates, Section 301 (China) duties, and Section 232 (Steel/Alu) measures, plus CBP fees like MPF and HMF calculated per 19 CFR regulations.

European Union (TARIC & CBAM)

Leverages the TARIC nomenclature. Landed costs include the EU-wide MFN duty plus national VAT rates. CBAM emissions are estimated using EC default intensities (Regulation 2023/956).
