Built for the people who move global trade.
SSLT Global is a free calculator and reference suite for international trade - Letters of Credit, freight, customs, Incoterms 2020 and commodity pricing. No login. No paywalls. No feature-gated pop-ups. Just 28 tools that do the job.
Interest uses per-currency day-count (ACT/360 vs ACT/365). Duty stacking follows regional VAT/GST rules. Incoterms map to UCP 600 / ISBP 745 wording. Every formula is documented on the tool page.
Every calculation serialises into a shareable link. Email your colleague a URL and they see exactly what you saw - no accounts, no seats, no signup.
Used by exporters, freight forwarders, LC ops teams and commodity traders across 50+ countries. Optimised for the reality of a trade desk: fast, keyboard-friendly, printable.
These tools are decision-support, not advice. HS classification, sanctions screening and LC drafting still require a licensed broker, compliance officer or banker. We say so clearly on every relevant tool.
Who we build for
- Exporters and importers preparing LC applications and quotes.
- Freight forwarders sizing CBM, chargeable weight and LCL/FCL breakpoints.
- Customs brokers modelling duty, VAT and landed cost across regimes.
- Trade finance and LC operations teams checking cost, tolerance and fees.
- Commodity traders converting units, moisture bases and basis differentials.

Editorial standards
Every calculator and guide on SSLT Global is written and reviewed against the current published texts of the standards it cites - not summaries or third-party paraphrases:
- UCP 600 (ICC Publication 600) and ISBP 745 - for all documentary-credit content.
- URDG 758 (ICC 758) and ISP98 - for demand guarantees and standbys.
- Incoterms® 2020 (ICC 723E) - for every risk, cost and delivery statement.
- IATA TACT - for air freight chargeable weight and dimensional-factor rules.
- WCO Harmonized System and the WTO Valuation Agreement (Art. VII GATT) - for HS classification and customs value.
- National tariff schedules and central-bank rate curves are cited where used.
Every guide carries a visible publish and last-modified date. Corrections and reader feedback are triaged weekly - send them via the contact page. We do not accept paid placements inside calculators or guides; sponsorship, when it appears, is clearly labelled.
