Customs Duty Calculator
Import duty = declared value × duty rate for your product's HS code, plus (in many countries) VAT/GST on the value + duty + freight. Enter the rate from your tariff lookup — this tool does the math, not the classification.

How the estimate works
Duty = customs value × duty rate %. Many countries compute customs value CIF-style (goods + freight + insurance). US de minimis allows shipments under $800 to enter duty-free for most goods (policy as of 2026 — verify current rules).

Formula and assumptions
CIF customs value = goods + freight + insurance (CBSA includes freight). FOB = goods value only. Duty = customs value × duty rate from your HS classification. VAT/GST = (customs value + duty) × rate in VAT countries. US de minimis: $800 for most goods. Classification and valuation are country-specific — confirm with a customs broker.

Customs Duty Calculator questions
How do I find my duty rate?
Classify your product to an HS code (harmonized system), then look up the rate in the destination country's tariff schedule. This calculator takes that rate as input.
What is the US de minimis threshold?
Shipments valued under $800 generally enter the US duty-free for most goods (section 321). Policy has been changing — verify current rules before relying on it.
Is freight included in customs value?
Often yes (CIF valuation) — goods + freight + insurance. The US generally uses FOB (goods only) for duty but adds freight for freight-statistical purposes. Enter the components that match your country's rule.
