Contact PortEntry
PortEntry is a small, independent, ad-supported site — there is no support team standing by, but a real person reads what comes in to support@portentry.com.
A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the import duty calculator, landed cost calculator, customs value calculator, trade currency converter, volumetric weight calculator, or container load calculator— and the figures you entered); a tool you wish existed on the site; an out-of-date fact or broken link in the blog, learn section, or the Trade & Customs Museum; or a bug in how a page looks or behaves on your device.
There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If a question is really about your specific shipment, its HS classification, or the duty on it, the official customs authority, a licensed customs broker, or your freight forwarder will have a more authoritative answer than this site can give; PortEntry’s tools produce general estimates, not customs rulings or professional advice, and the site isn’t affiliated with any customs authority, carrier, or financial institution.
Before writing in about a tool result, it can help to double-check the numbers you entered — the customs value, duty rate, freight and insurance figures, carton dimensions, or the exchange rate are the most common source of a surprising answer. If it still looks wrong after that, that’s exactly the kind of message worth sending.
