Frequently Asked Questions

How much does a customs broker cost?

Greenwich Mercantile charges a flat $100 per filing — any shipment, any size. There are no surcharges, hidden fees, or variable pricing. You know exactly what you'll pay before your cargo moves.

How long does it take to file a customs entry?

Every filing is guaranteed to be completed within 30 minutes of receiving your documents. That's not an average — it's our service level agreement.

How can a customs broker help reduce duty costs?

Most brokers file what they're handed. Greenwich Mercantile conducts expert-led tariff classification reviews to identify opportunities to legally reduce your duty spend. Incorrect or outdated HTS codes are one of the most common reasons importers overpay.

What happens if my shipment is held at the border?

Customs holds typically result from classification errors, missing documentation, or compliance flags. Greenwich Mercantile's process is designed to prevent holds before they happen through accurate filings and proactive compliance checks. If an issue does arise, our team resolves it directly with CBP on your behalf.
