US Ecommerce Sellers: Confirm IOR, USPPI, and Form 5106 Before Shipping

The importer of record is the party legally responsible for customs duties, accurate classification, and compliance on goods entering a country. On the export side, U.S. rules do not use a formal “exporter of record” title at all: they assign responsibility through the U.S. Principal Party in Interest, or USPPI. If you sell across borders, check now who is named on your entry paperwork and who is filing your export data, because that answer determines who carries the liability.

TL;DR:

• The importer of record is responsible for customs duties, valuation, and compliance, while the USPPI handles export licensing and data filing in routed export transactions.
• CBP limits the legal import of record to the owner, purchaser, or licensed customs broker, making accurate Form 5106 crucial to avoid shipment delays or penalties.
• The sales contract and Incoterms definitively determine who acts as the importer of record; ambiguity can lead to unintentional liability shifts.
• Red flags include vague Incoterms, third-party EINs, or brokers unable to produce valid IOR and POA documentation, which can cause legal and compliance issues.
• Managing DDP shipping reduces the complexity but does not eliminate the need for verifying legal responsibilities, especially the correctness of documentation and IOR identity.

Key differences at a glance between IOR and exporter duties

The importer of record and the party handling export tasks answer to different rulebooks, and mixing them up is where most sellers get burned.

• Customs entry and duties: the importer of record signs for the shipment, pays duties and tariffs, and answers for valuation and tariff classification at the border.
• Export licensing and filing: the USPPI, or an authorized agent in a routed transaction, determines whether a license or ECCN applies and who submits the Electronic Export Information.
• Practical signpost: if your name appears on the customs entry, you are the importer of record; if your business is the one selling and shipping goods out of the country, you are usually the USPPI, not an undefined “exporter of record.”

Sellers who assume a forwarder automatically absorbs these duties often discover otherwise only after a shipment gets flagged.

What U.S. export law says about the exporter and routed exports

U.S. export regulations do not recognize “exporter of record” as an official designation. Instead, the Export Administration Regulations define the USPPI as the U.S. entity that generally acts as the exporter for standard, non-routed shipments, and the Foreign Principal Party in Interest, or FPPI, as the overseas buyer. In a routed export transaction, the FPPI can authorize its own U.S. agent to handle export filing instead of the USPPI, but that authorization must be in writing and can cover multiple shipments between the same two parties.

Filing the Electronic Export Information through the Automated Export System is restricted to certified AES participants, and whoever files carries responsibility for the information’s truth, accuracy, and completeness. Trade guides echo this directly: there is no formal legal term “exporter of record” anywhere in the EAR, the Foreign Trade Regulations, or ITAR. Assigning that role informally in a contract, without matching it to USPPI or authorized-agent status, creates a gap that customs enforcement can exploit later.

Who can legally be importer of record and why it matters

CBP limits who may lawfully make entry as importer of record to three categories: the owner of the goods, the purchaser of the goods, or a licensed customs broker acting on their behalf. A Customs Directive on the right to make entry makes clear that a nominal consignee, which describes most freight forwarders, cannot serve as importer of record unless it is also a licensed broker filing under that authority.

This matters because the importer of record bears the duty payment obligation and the classification liability, not just the paperwork burden. If classification is wrong or duties go unpaid, CBP pursues the importer of record, regardless of who physically prepared the entry documents.

CBP has also sharpened its focus on the accuracy of importer of record data tied to Form 5106, the form that registers an importer’s identity and IOR number. Inaccurate or incomplete Form 5106 information can result in that number being voided, halting shipments until the record is corrected.

Importer responsibilities and the paperwork sellers must track

Every import relies on a specific paperwork trail, and knowing which document belongs to which party keeps a shipment from stalling at the border.

• Entry forms: the CBP entry documents identify the importer of record and must match the name and IOR number on file.
• EEI and AES filings: the party filing export data, whether USPPI or an authorized agent, is accountable for its accuracy under the Foreign Trade Regulations.
• Form 5106: registers the importer’s identity and IOR number with CBP and must stay current.
• Power of attorney: authorizes a broker to file entries or export data on the importer’s or exporter’s behalf.
• Commercial invoice and valuation records: support the declared value and classification used to calculate duties.

Definition: an importer of record is the party responsible for ensuring imported goods comply with customs laws, a role logistics providers confirm can be filled by a designated broker acting under proper authorization. A bond is also typically required to guarantee duty payment, and its terms depend on shipment frequency and value.

How Incoterms decide who becomes importer of record

The sales contract, not habit or assumption, determines who ends up filing as importer of record or handling export paperwork. Three common scenarios show how that plays out.

1. DDP (Delivered Duty Paid): the seller typically acts as importer of record, prepaying duties and managing customs clearance so the buyer receives goods with nothing left to settle.
2. DAP, EXW, or FOB: the buyer usually becomes the importer of record and arranges its own customs clearance once goods reach the border or the agreed delivery point.
3. Routed export transactions: the foreign buyer’s U.S.-based agent may act as the exporter for filing purposes, but only with a written authorization from the FPPI on record.

Ambiguous Incoterms language is one of the most common ways sellers end up unintentionally holding, or unintentionally dodging, import liability they never discussed.

Practical checklist and red flags before assigning IOR duties

Before you let a contract or a vendor’s default process decide who carries import liability, run through a short list.

• Confirm your business name and IOR number are the ones listed on Form 5106, not a third party’s.
• Obtain written routed-export authorization whenever a foreign buyer’s agent will file on your behalf.
• Verify your broker’s license number and get a signed power of attorney on file.
• Collect and confirm your own EIN and commercial invoice details rather than relying on a partner’s.

Pro Tip: Ask any broker or forwarder to show you their IOR number and POA documentation before you agree to let them file on your behalf.

Watch for red flags: vague Incoterms in a contract, a vendor asking to use someone else’s EIN, or a broker who cannot produce a power of attorney or an IOR number on request. Any of these signals that liability is being shifted informally, which rarely holds up once CBP asks questions.

How a managed DDP partner narrows the risk without erasing it

A managed DDP arrangement centralizes customs clearance, duty payment, and delivery into one workflow, which is why smaller sellers often prefer it over coordinating a broker, a forwarder, and a customs filing separately. That said, outsourcing the paperwork does not remove your duty of reasonable care. You still need to verify document accuracy, confirm who is legally listed as importer of record, and keep your own Form 5106 records current, even when a partner is filing on your behalf. For more on how brokers and forwarders divide these duties, see ForwarderOne’s comparison of customs brokers and freight forwarders.

What sellers consistently get wrong about compliance

The most common mistake I see is sellers assuming that hiring a forwarder automatically transfers legal liability away from them. It usually does not, unless a licensed broker is formally named as importer of record with proper documentation. A close second is treating Form 5106 as a formality rather than a legal filing, and writing Incoterms into contracts so loosely that nobody can say who owes duties until a shipment is already stuck at the border. The fix is not complicated: put it in writing, confirm the broker’s license and POA, and verify the IOR number belongs to you before goods ship.

Where ForwarderOne fits for sellers managing this risk

If you are moving inventory from China or Korea into fulfillment centers and want the customs side handled inside one workflow, ForwarderOne’s DDP Shipping service manages customs clearance, duty payment, and delivery together rather than splitting them across separate vendors. It suits sellers dealing with repeated customs delays, complex tariff lines, or no existing broker relationship of their own.

Each account works with a manager to assist with shipment inquiries, which is helpful during busy shipping periods. Check availability for your next shipment through ForwarderOne’s FBA freight forwarding page.

FAQ

What is the difference between an exporter and an importer?

An exporter, or USPPI under U.S. rules, is the party sending goods out of the country and is generally responsible for export filing accuracy. An importer of record is the party receiving goods who answers for customs duties, classification, and compliance at the border.

What is the difference between EOR and IOR?

“Exporter of record” is not an official U.S. legal term. The recognized U.S. designation is USPPI, while importer of record, or IOR, is a formally defined role limited to the owner, purchaser, or a licensed customs broker.

How do you tell if you are the importer of record?

You are the importer of record if your business name and IOR number appear on Form 5106 and the customs entry documents for that shipment. If a broker or forwarder is filing without your name attached, someone else may be holding that liability instead.

Is it better to import or export?

Neither role is inherently better since each carries distinct legal duties tied to the direction goods are moving. What matters is confirming your role in the transaction and making sure your contract, Incoterms, and paperwork reflect that role accurately.
