CBP Form 3311: Filing Steps, Documents, and Submission Options

CBP Form 3311, the Declaration for Free Entry of Returned American Products, is the one-page form you file with U.S. Customs and Border Protection to bring qualifying goods back into the country duty-free under Harmonized Tariff Schedule subheading 9801.00.10.¹ To use it, you complete the form’s short set of fields, attach supporting documents proving U.S. origin when the shipment’s value or markings require them, and submit two copies to the CBP officer at the port of entry or file the electronic equivalent through the Automated Commercial Environment. The form covers both commercial shipments and personal belongings, provided the goods were not improved in value or condition while abroad.

What Goods Qualify

Two categories of goods can enter duty-free under 9801.00.10. Products manufactured in the United States can return at any time after export with no deadline. Foreign-made products that were previously in the U.S. and exported can also return duty-free, but only within three years of the export date.²

Both categories share one non-negotiable condition: the goods cannot have been “advanced in value or improved in condition by any process of manufacture or other means while abroad.” Repairs, upgrades, additional assembly, or repackaging that adds commercial value can all disqualify the shipment. A U.S.-made machine sent overseas and returned with a replaced motor or upgraded software no longer qualifies, and would be dutiable on its full value as a foreign article.³ Minor wear, dirt, or incidental use are not improvements. The test is whether some process increased the article’s commercial worth.

There is also a drawback bar. If a duty drawback (a refund of duties paid on imported materials used in an exported product) was received when the goods were originally exported, you cannot also claim duty-free re-entry. If a drawback claim was filed at export, it must be formally abandoned before the goods can qualify on Form 3311.⁴

One boundary worth flagging: goods manufactured inside a U.S. Foreign Trade Zone are treated as foreign-made for tariff purposes, so they fall under the three-year foreign-goods window rather than the unlimited window for domestic products.⁵

Filling Out the Form

The form itself is a single page. Work through it in order:

Port and date. The U.S. port where the goods are arriving and the date of entry.
Marks, numbers, and description. Identifying marks and numbers on the shipping containers or packages, plus a plain description of each item. Include brand, model, and serial numbers where they exist so an officer can match the cargo to your paperwork.⁴
Value. The value in U.S. dollars, based on original purchase price or current market worth.
Drawback status. Check the box marking drawback as “CLAIMED” or “UNCLAIMED.” Even when no drawback was ever involved, you must affirmatively mark it as unclaimed.
Declaration and signature. The owner, importer, consignee, or authorized agent signs under penalty of law.⁶

If a corporation is the importer, the declaration can be signed by a president, vice president, secretary, or treasurer, or by an employee or agent holding a valid power of attorney and a certification that the signer has knowledge of the relevant facts.⁷

Supporting Documents You May Need

Documentation requirements scale with the shipment’s value.

For shipments over $2,500, 19 CFR 10.1 normally requires two additional declarations alongside the completed Form 3311.⁷ The first is a foreign shipper declaration, a written statement from the person shipping the goods back confirming the articles were originally exported from a specific U.S. port on an approximate date and are returning without having been advanced in value or improved in condition. The second is an owner or importer declaration confirming the foreign shipper’s statement, identifying the original U.S. manufacturer by name and location, and affirming no drawback was paid.

The regulation gives CBP officers a practical out. When the officer is satisfied the articles are clearly U.S. products, have not been improved abroad, and no drawback was paid, both supporting declarations can be waived and no bond is required.⁶ Clearly labeled American-made goods and obvious personal effects often clear this way.

For shipments valued at $10,000 or more that are not clearly marked with the U.S. manufacturer’s name and address, the form directs you to attach documentation proving domestic origin. Manufacturer affidavits, original export invoices, and bills of lading from the initial shipment all work. The stronger the paper trail linking the goods to their original U.S. export, the faster clearance goes.

Submitting the Form

How you file depends on the shipment.

Paper at the Port

For personal belongings and smaller commercial loads, file two completed copies of Form 3311 directly with the CBP officer at the port of entry. The regulation requires the form be “filed in duplicate.”⁶ Bring the supporting documents (foreign shipper declaration, export invoices, manufacturer affidavits) so the officer can review everything at once. If the officer is satisfied with origin and condition, release can happen on the spot.

Electronically Through ACE

Commercial importers can file electronically through the Automated Commercial Environment. The regulation recognizes “CBP Form 3311, or its electronic equivalent.”⁶ Most commercial filers use a licensed customs broker who handles the ACE submission as part of the broader entry process, which generally means faster processing and easier integration with other trade data.

What Happens After You File

If the documentation is complete and nothing is flagged, CBP releases the goods without assessing duties. Some shipments get a physical examination in which officers compare the cargo against the description on the form to verify no work was done abroad. A quantity mismatch, signs of repair, or packaging that suggests remanufacturing can trigger a hold or full inspection.

Once the goods are released, keep copies of the filed Form 3311 and all supporting documents for five years from the date of entry. That retention period is set by 19 CFR 163.4 and applies to all records related to a customs entry.⁸ CBP can conduct post-entry audits during that window, and your records are what defend the duty-free claim.

Common Mistakes That Delay Clearance

A vague goods description is the most frequent problem. Writing “machinery” or “personal items” forces the officer to inspect everything physically, which can add days. Describe each article specifically enough that it can be matched to the original export paperwork.

Understating value draws scrutiny. If the declared value looks implausibly low for the type and quantity of goods, expect questions. Use the original purchase price or a defensible current market value and keep the supporting records accessible.

Leaving the drawback checkbox blank creates unnecessary back-and-forth. Even when no drawback was ever claimed, mark the box as “UNCLAIMED.”⁴

Arriving without a foreign shipper declaration on a high-value shipment that is not clearly marked as American-made is a gamble. The officer has discretion to waive it, but that discretion cuts both ways, and the shipment sits until you produce the documentation. For anything over $2,500 that is not obviously U.S.-origin, prepare the supporting declarations in advance rather than hoping for a waiver at the port.⁷
