Jinsi ya kukokotoa Customs Tariff Duty

Customs Tariff Duty ni nini?

The Customs Tariff Duty Calculator determines the exact import duty owed on goods entering a country by looking up the Harmonized Tariff Schedule (HTS) code and applying the corresponding ad valorem, specific, or compound duty rate to the declared customs value.

Fomula

Duty = Customs Value × Ad Valorem Rate (%) + Specific Duty per Unit × Quantity

CV: Customs Value ($) — Declared transaction value of imported goods including adjustments
R: Ad Valorem Rate (%) — Percentage duty rate from the HTS schedule
S: Specific Rate ($/unit) — Fixed duty amount charged per unit of measure
Q: Quantity (units) — Number of units imported in the applicable unit of measure

Maswali yanayoulizwa mara kwa mara

What is the difference between ad valorem and specific duty?

Ad valorem duty is a percentage of the goods value (e.g., 5%), while specific duty is a fixed amount per unit (e.g., $0.50 per kilogram). Some goods have compound duties combining both.

How do I find the correct HTS code for my product?

Use the USITC HTS search tool at hts.usitc.gov, consult a licensed customs broker, or request a binding ruling from CBP for certainty.

Does customs duty apply to samples or gifts?

Generally yes, unless the shipment qualifies under the de minimis threshold ($800 in the US) or falls under a specific exemption for bona fide samples of negligible value.
