⚠️ These are estimates only. Actual duty rates depend on the precise 10-digit HTS code for your product. Additional Section 301 tariffs (25%+) may apply to Chinese goods. Always consult a licensed customs broker before importing. CBP.gov has the official Harmonized Tariff Schedule.

How US Import Duties Work
US customs duties are calculated on the customs value of goods — typically the transaction price (what you paid) plus international shipping and insurance to the US port of entry (CIF value). The duty rate is determined by your product's HTS (Harmonized Tariff Schedule) code.
// Landed cost formula
Customs value = FOB price + freight + insurance
Duty = Customs value × duty rate %
MPF = 0.3464% of customs value (min $31.67, max $614.35)
HMF = 0.125% of customs value (ocean only)
Landed cost = goods + freight + insurance + duty + MPF + HMF + customs broker
Customs value = FOB price + freight + insurance
Duty = Customs value × duty rate %
MPF = 0.3464% of customs value (min $31.67, max $614.35)
HMF = 0.125% of customs value (ocean only)
Landed cost = goods + freight + insurance + duty + MPF + HMF + customs broker
What is Section 301 tariff and does it apply to my goods?
Section 301 tariffs are additional duties (7.5%–25%) applied to most goods from China, implemented starting in 2018. They are on top of the standard MFN duty rate. If you're importing from China, your effective duty rate may be significantly higher than the standard HTS rate. Check the USTR Section 301 exclusion list — some products have been excluded. Sourcing from Vietnam, India, or other countries can eliminate Section 301 exposure.
When do I need a customs broker?
You are legally required to use a licensed customs broker (or file yourself as the importer of record) for formal entry — shipments valued over $2,500. For commercial imports, a customs broker is strongly recommended regardless of value. Customs broker fees run $100–400 per shipment. For regular importers, building a relationship with a broker saves far more in avoided penalties, holds, and classification errors than the broker fee costs.
