How to Handle Customs When Moving from Portugal to the USA

Every household shipment from Portugal to the USA has to clear US Customs before it reaches your new address, and the process is more predictable than most people assume once you know what it actually checks for. This is the step-by-step version, including the specific items that trip up Portuguese shipments most often. For the broader rules that apply to any country, see our complete guide to international customs regulations; what follows here is specific to the Portugal corridor.

Step 1: Figure Out Which Category You Fall Into

US Customs treats returning citizens, green card holders, and temporary visa holders somewhat differently. If you’ve lived outside the US for at least a year, you generally qualify for duty-free entry on used household goods. If you’re arriving on a work or study visa, you can typically bring personal effects duty-free too, but anything you intend to keep in the US permanently after your visa ends may need to be declared differently. Confirm your category before you finalize your inventory list, since it changes what documentation you’ll need.

Step 2: Gather the Actual Documents

Customs Form 3299 is the core document for duty-free entry of household goods, and it needs to be accurate, not just complete. Alongside it, you’ll need a bill of lading from your shipping provider, proof of legal entry into the US such as a visa or green card, and a full itemized inventory with descriptions, approximate values, and how long you’ve owned each item. If a customs broker is handling clearance on your behalf, they’ll also need power of attorney. Keep multiple copies of everything; customs officials at different stages of the process sometimes ask for the same document twice.

Step 3: Know What’s Actually Restricted

This is where Portuguese shipments run into more friction than people expect, and it’s almost always about food, not furniture. Cured meats like presunto and chouriço are generally prohibited from personal import regardless of country of origin, since fresh, cured, and dried meat products are restricted under USDA rules meant to prevent animal disease transmission. Hard and semi-hard cheeses are usually fine; Serra da Estrela and other firmer Portuguese cheeses generally clear without issue. Wine, including Port, isn’t prohibited, but it’s subject to federal excise limits and, depending on your destination state, state alcohol import rules, so check both before you pack a case. Olive oil travels without issue, since it carries none of the meat or dairy restrictions that apply to other foods. Household items with no food content, including azulejo tiles and other ceramics, don’t raise customs concerns on their own. Wooden furniture and antiques don’t need to be left behind, but some pieces may require fumigation documentation if they show signs of pest activity, which is worth having your shipping company flag before the container is sealed rather than after it’s inspected.

Step 4: Understand What You’ll Actually Pay

Most used household goods you’ve owned for over a year enter duty-free. New items, or anything purchased specifically to bring to the US, are assessed duty based on declared value, so it’s worth being honest and specific on your inventory rather than under-describing higher-value items, which tends to draw more scrutiny, not less. If you’re shipping a vehicle in the same container, expect a separate duty of roughly 2.5% of declared value for a passenger car; trucks are taxed at a different rate.

Step 5: Where Your Shipment Actually Lands

Most Portugal-to-USA household shipments leave from Lisbon’s Alcântara terminal or the Port of Leixões near Porto, and arrive at one of a handful of major East Coast ports, commonly New York, Norfolk, or Savannah, depending on which carrier and routing your shipping company uses. Once your shipment reaches a US port, Customs and Border Protection verifies your documents against the physical contents. Most shipments clear without a full inspection if the paperwork matches what’s actually in the container. Shipments do get pulled for physical inspection, though, and the single most common trigger we see is a mismatch between what’s declared and what’s found, whether that’s an incomplete inventory, an item description vague enough to raise questions, or an undeclared food item packed in with household goods.

How Long Clearance Actually Takes

A straightforward clearance, where the paperwork matches the contents, typically adds a few days to your overall timeline once the container reaches port. An inspection changes that considerably; it can add a week or more, since your shipment sits until an officer works through it item by item against your inventory list. The documentation step isn’t paperwork for its own sake. It’s the difference between those two outcomes.

If You Hit a Delay

Keep your shipping company’s contact information and your CBP port office details on hand, and have a plan for a week or two without your belongings just in case. Most delays resolve with additional documentation rather than turning into a real problem, but knowing who to call the same day matters more than knowing the rule in advance.
