When shipping cargo into the United States, **U.S. Customs and Border Protection (CBP)** is the agency responsible for clearing shipments, enforcing trade regulations, and collecting customs revenues. Understanding the components of a CBP customs bill prevents unforeseen payment delays.
1. Formal vs. Informal Customs Entries
CBP classifies imports based on transaction value and commercial intent:
* Informal Entry: Typically used for commercial shipments valued under **$2,500 USD** (and personal passenger baggage). It does not require a customs bond, and clearing paperwork is simplified.
* Formal Entry: Mandatory for all commercial shipments valued over **$2,500 USD** (and restricted items of any value). A formal entry requires a **Customs Bond** and detailed declaration paperwork filed by a licensed customs broker.
2. CBP Duty Calculation Base
CBP assesses duties using the FOB (Free on Board) transaction value (the price paid for the goods excluding shipping and insurance fees). CBP applies standard HTSUS duty rates to this value.
3. CBP User Fees
CBP charges additional processing fees to fund border operations:
* Merchandise Processing Fee (MPF): Charged on all entries. For formal entries, the rate is 0.3464% of FOB value (min $31.67, max $614.35).
* Harbor Maintenance Fee (HMF): Charged at 0.125% of goods value strictly on cargo arriving via maritime transport (ocean ports).
