Greenwich Mercantile

For mid-market and enterprise

Customs brokerage that lowers your duty and catches paperwork gaps before goods ship.

Customs brokerage for enterprise importers: lower duty, fewer holds caused by missing paperwork, and every entry filed by a licensed U.S. customs broker.

Service scope, responsibilities and fees are agreed in writing. No guarantee of clearance or savings.

What our customs brokerage services cover

Many customs broker services start when the goods reach the port. Greenwich Mercantile starts while the goods are still with the supplier, so duty and paperwork questions are settled before customs clearance begins.

Greenwich pairs a duty reduction app and a pre-entry audit app with licensed U.S. customs brokers who file every entry.

How duty savings are found before the entry is filed

Many import programs pay more duty than the law requires, because of a default tariff code nobody has checked in years, a declared value that includes non-dutiable costs, or an origin nobody documented.

Greenwich's duty reduction app reviews classification, origin and valuation across the whole SKU catalog before the goods ship. Classification sets the rate, origin decides which duty measures and trade programs apply, and valuation decides what the rate is charged on, including first sale valuation when you buy through a trading company or agent.

A licensed U.S. customs broker reviews and signs off every duty position before it is used on an entry. Rates under measures such as Section 301 and Section 232 change often, so the broker confirms the rate for each entry date.

We helped one medium-sized European skincare company find $305,000 in annual duty savings. Any saving depends on your actual products and documents.

Fewer holds caused by missing or inconsistent paperwork

A container held at the port can miss a seasonal launch or a retailer's delivery window, and late stock often sells at a markdown.

Many holds start with paperwork: an invoice that does not match the packing list, a label that does not match the fiber content or ingredients, an origin claim with no evidence, or agency data missing when the goods arrive.

Greenwich's pre-entry audit app checks supplier documents against each other and against the product record before the goods ship. Anything missing or inconsistent goes back to the supplier while the goods are still at the factory.

CBP and partner agencies such as FDA can still examine or hold any shipment. The pre-entry audit targets holds caused by missing or inconsistent paperwork, which can be fixed before the goods leave the supplier.

The product record also supports customs compliance after release: importers must keep entry records for five years, and CBP questions are answered from the file.

A licensed customs broker files every entry; you stay the importer of record

Greenwich Mercantile does the customs work with AI, and a licensed U.S. customs broker reviews the duty position and files every entry under your power of attorney: one of our partner brokers, or your existing broker working from the same record.

CBP licenses customs brokers under 19 CFR Part 111, and a broker must hold the importer's power of attorney before transacting customs business in the importer's name.

Your company is always the importer of record and pays the duty. Greenwich and its broker partners never act as importer of record and never lend a name, bond or address.

Greenwich helps you set up as the importer of record (CBP Form 5106, customs bond) and runs the import work as your agent; a licensed broker files under your power of attorney.

European companies can import in their own name as non-resident importers. Since September 18, 2026, CBP has applied stricter checks to Form 5106 registrations, so Greenwich checks the registration against company records before it is filed.

Importers looking for a digital customs broker get the software and a licensed broker together: the broker holds the license and files the entry.

Keep your current customs broker, or switch to our broker partner

You do not have to change customs brokers to work with Greenwich: your existing broker can file from the same product record and document pack.

Importers who prefer to switch sign a power of attorney with Greenwich's broker partner, choose the switch date, and keep their current broker filing until then.

The work runs from the files and exports you already have: past entry summaries (CBP Form 7501), commercial invoices, product lists and supplier documents.

How pricing works: quoted in writing before your first shipment

Customs broker fees depend on entry volume, lines per entry, agency filings and how much review the catalog needs, so Greenwich does not publish a price list.

Greenwich scopes the work first, and the scope and fee are quoted in writing before your first shipment. The written quote states what is included and what is charged separately, such as duty, government fees, the bond premium, and exam or storage costs.

Greenwich's first piece of work is usually one product category or one sourcing country, with a defined output and a delivery date.

When comparing customs broker cost across proposals, compare the scope of work as well as the per-entry fee.

Customs brokerage for fashion, beauty, food and consumer goods importers

Greenwich works with mid-market and enterprise importers, including European companies, that bring in hundreds of SKUs from many suppliers against seasonal launches and retailer delivery windows.

Fashion and apparel entries turn on fiber content, knit or woven construction, textile origin rules and cotton tracing. Beauty and cosmetics entries depend on MoCRA registration and listing, approved color additives, and the line between cosmetics and over-the-counter drugs such as sunscreens.

Food and beverage entries need FDA Prior Notice, registered facilities and an identified FSVP importer. Consumer goods entries often need CPSC certificate data for children's and other regulated products, country of origin marking, and consistent classification across large catalogs.

Guides on customs brokerage

Greenwich's guides explain what customs brokers do, what they cost, how licensing works and how to choose one.

Questions, answered directly.

What do customs brokerage services include?

Customs brokerage services cover classifying the goods, filing the entry and entry summary with CBP, filing ISF for ocean freight, sending agency data such as FDA Prior Notice, and following each shipment to release. Greenwich Mercantile adds a duty reduction review and a check of the supplier documents before the goods ship, and a licensed U.S. customs broker files every entry.

Who files the entry with U.S. Customs?

A licensed U.S. customs broker reviews and files every entry under your power of attorney: one of our partner brokers, or your existing broker working from the same record. Greenwich Mercantile does the customs work behind each entry with AI: the product record, the duty review and the pre-entry document pack.

Who is the importer of record when Greenwich runs our imports?

Your company is always the importer of record and pays the duty; Greenwich and its broker partners never act as importer of record or lend a name, bond or address. Greenwich helps you set up as the importer of record (CBP Form 5106, customs bond), and a licensed broker files under your power of attorney.

Can we keep our existing customs broker?

Yes, you can keep your existing customs broker. Your broker files from the same product record and document pack that Greenwich builds, and moving the filing to Greenwich's broker partner is an option, not a requirement.

How much do Greenwich's customs brokerage services cost?

Greenwich quotes the scope and fee in writing before your first shipment, based on your products, entry volume, ports and agency filings. Greenwich's written quote states what is included and what is charged separately, such as duty, government fees, the bond premium and exam or storage costs.

How does Greenwich find duty savings before an entry is filed?

Greenwich reviews classification, origin and valuation across your SKU catalog before the goods ship, looking for products that pay duty on a default code, a value that includes non-dutiable costs, or an undocumented origin. A licensed U.S. customs broker reviews and signs off every duty position before it is used on an entry. We helped one medium-sized European skincare company find $305,000 in annual duty savings.

How does Greenwich reduce holds at the border?

Greenwich's pre-entry audit checks the invoice, packing list, origin evidence and agency data against each other before the goods ship, and sends anything missing or inconsistent back to the supplier. The pre-entry audit targets holds caused by missing or inconsistent paperwork, and CBP and other agencies can still examine or hold any shipment.

What documents does Greenwich need to start?

Greenwich needs a product list or SKU export, recent commercial invoices and packing lists, and past entry summaries (CBP Form 7501) if you have imported before. Supplier documents such as origin evidence, fiber content, ingredient lists or FDA registration details follow for the products reviewed first.
