US customs FAQ

US duties from Canada, answered

This calculator models MFN, Section 301, CBP MPF/HMF, informal vs formal entry, and USMCA — then PrepKingz can prep and clear the shipment from Montreal.

For sellers importing into the United States from Canada. Confirm classification and entry with a licensed broker.

How do I calculate US customs duties from Canada?

Duties equal customs value × (MFN + China Section 301 if origin is China + forced-labor Section 301 by country), each line rounded to the cent. Add CBP MPF, ocean HMF, broker, and a bond on formal entries. This page runs that formula with current rates.

What is the US MPF and when is informal entry allowed?

Merchandise Processing Fee (MPF) is $2.77 on automated informal entries at or under $2,500 USD. Formal entries pay 0.3464% of value, minimum $34.58 and maximum $670.86 (CBP FY2027). Value over $2,500 requires a formal entry and a bond.

How does Section 301 China affect my US import?

If country of origin is China, add the list rate on top of MFN — List 4A is 7.5%, Lists 1–3 are typically 25%, with 2024 review rates of 50% or 100% on some codes. Routing through Montreal does not change Chinese origin.

Does USMCA (CUSMA/ACEUM) zero out US duties?

For Canada or Mexico origin with a valid certification, MFN and forced-labor 301 drop to 0% in this calculator. China Section 301 still only applies to Chinese origin. Keep the USMCA certificate of origin on file.

What is Harbor Maintenance Fee (HMF)?

HMF is 0.125% of customs value and applies to ocean (maritime) arrivals only — not truck, air, or courier in this model.

Does PrepKingz handle US customs clearance from Montreal?

PrepKingz preps inventory in CAD at 111 Chabanel, prepares commercial invoices and USMCA docs, and coordinates licensed brokers and cross-border freight to US Amazon FCs, WFS, and DTC. We are not a licensed customs broker; this calculator is an estimate only.
