TariffsChart launch guide

How TariffsChart estimates duties, taxes, landed cost, pricing assumptions, saved scenarios, and SKU classification context before a shipment.

What is TariffsChart?

TariffsChart is a tariff and landed-cost planning workspace for importers, cross-border sellers, sourcing teams, and operators. The public product now has two layers:

A free calculator that turns shipment assumptions into a landed-cost chart.
A signed-in workspace that preserves the assumptions behind each estimate for broker review, internal review, and repeat SKU planning.

TariffsChart is not an official customs database and does not replace a licensed customs broker. It helps teams structure the question, preserve source evidence, compare scenarios, and create a review packet before a purchase order, quote, or product launch.

What is live now?

The free calculator supports:

Product description, SKU, and HS/HTS code
Origin and destination country or region
Currency, quantity, goods/customs value, freight, and insurance
FOB/EXW versus CIF valuation assumptions
Base duty rate and additional tariff or trade-remedy rate
Import tax/VAT/GST rate and fixed fees
Target gross margin and suggested unit price
Source name, source link, source confidence, source capture date, and notes
Copyable summaries, shareable links, CSV export, broker packet export, and a cost breakdown chart
Quick comparison variants for alternate origin, freight risk, and target margin

The signed-in workspace supports:

Saved shipment scenarios
Scenario status: draft, broker review, confirmed, archived
Scenario duplication for comparing supplier origin, freight, tariff, or margin assumptions
Broker-ready Markdown packets with product, route, rates, source evidence, formulas, open questions, and disclaimer
Private broker-review links for Pro beta and Team pilot users; reviewers can mark a scenario confirmed or needs more information
SKU catalog records with product description, candidate HS code, origin, supplier, notes, and classification status
Source snapshots with official or broker source URL, retrieval date, route, HS/HTS code, confidence label, and notes
A China → United States official source research workflow that can attempt USITC HTS lookup, generate structured HTS/CROSS/Section 301/USTR/AD-CVD/IEEPA checks, and save source snapshot drafts
Tariff change alerts for Pro beta and Team pilot users, with official-source fingerprints, manual checks, scheduled checks, and an alert review queue

How the estimate is calculated

For FOB/EXW scenarios, TariffsChart treats freight and insurance as part of the dutiable value. For CIF scenarios, TariffsChart assumes the goods/customs value already includes freight and insurance.

Dutiable value = goods/customs value + freight + insurance, unless CIF is selected
Base duty = dutiable value × base duty rate
Additional tariff = dutiable value × additional tariff rate
Import tax base = dutiable value + base duty + additional tariff + fixed fees
Import tax = import tax base × import tax/VAT/GST rate
Landed cost = dutiable value + duties + import tax + fixed fees
Unit cost = landed cost ÷ quantity
Suggested unit price = unit cost ÷ (1 - target gross margin)

What users must verify

Before making a binding filing, purchase, or customer quote, verify:

HS/HTS classification
Whether the declared value and Incoterms treatment match the destination country’s customs rules
Preferential rates, free-trade-agreement eligibility, tariff exclusions, and quota treatment
Anti-dumping duties, countervailing duties, safeguard duties, Chapter 99 classifications, and other trade-remedy measures
The import-tax base for the destination country
Final broker, carrier, platform, and payment fees

Current product boundary

The product can now support early paid-user conversations because it is no longer only a generic calculator. The first paid promise should still be narrow: “never lose the assumptions behind a tariff estimate.”

The next paid milestones are stronger official-source parsing, country-pair data connectors beyond China → United States, team roles, bulk SKU workflows, and email notifications for saved HS/origin/destination combinations.
