Importer of Record (IOR) and Customs Bond Explained
Two terms can determine whether an ocean shipment clears smoothly in the United States: Importer of Record and Customs Bond. This guide explains who carries the legal responsibility, what the bond guarantees and what importers should confirm before cargo leaves China.
Importatore ufficiale (IOR)
The company or person legally responsible for entering the goods, declaring them correctly, paying duties and meeting US import requirements.
Customs Bond
A financial guarantee protecting US Customs and Border Protection if the importer fails to pay amounts due or meet bonded obligations.
In one sentence: the IOR is the responsible importing party; the Customs Bond guarantees that party’s obligations to CBP.
Why IOR and Bond Must Be Confirmed Before Shipping
When cargo is shipped by sea from China to the United States, the forwarder can arrange pickup, booking, export customs, ocean freight and destination coordination. However, a logistics company cannot simply invent a US importer after the vessel sails.
The parties should confirm the real Importer of Record, importer number, Customs Bond, customs broker authorization, ISF filing responsibility, tariff classification and product compliance before loading. This is especially important for door-to-door and DDP shipping.
What Is an Importer of Record?
The Importer of Record is the party identified to US Customs and Border Protection as responsible for the import entry. In practical terms, the IOR is the party whose name and importer identification are used to bring the goods formally into the United States.
Accurate Declaration
The IOR is responsible for reasonable care in tariff classification, customs value, country of origin and the accuracy of information declared to CBP.
Duty and Fees
The IOR is responsible for duties, taxes and applicable fees, including additional amounts that may be assessed after entry.
Product Compliance
The IOR must address applicable requirements from agencies such as FDA, FCC, EPA, CPSC or USDA when the product falls under their jurisdiction.
Recordkeeping
Import records and supporting documents must be retained and made available when legally required.
Customs Enquiries
The IOR may need to respond to CBP requests, examinations, notices, audits, valuation questions or post-entry adjustments.
Broker Authorization
The IOR normally authorizes a licensed customs broker through a Power of Attorney, but appointing a broker does not transfer away all importer responsibility.
Who Can Act as the IOR?
Depending on the commercial arrangement and eligibility, the IOR may be the US buyer, owner, purchaser, consignee, a qualifying foreign importer or another party with a legitimate financial interest and the legal right to make entry.
| Possible IOR | Typical situation | What must be checked |
|---|---|---|
| US buyer or customer | FOB, CIF, DAP or other buyer-controlled imports | Importer number, bond, broker POA and willingness to accept import responsibility |
| US subsidiary or affiliated company | Regular inventory imports for a group | Corporate relationship, purchase records, entry data and compliance controls |
| Foreign seller as non-resident importer | Seller-managed programs and some DDP structures | CBP registration, US agent, bond, broker arrangement, tax implications and agency requirements |
| Qualified third-party IOR provider | Special projects where the service is legally available | Written scope, ownership/financial interest, product eligibility, liability and recordkeeping |
Never use an unrelated company’s EIN or importer number without its knowledge and authorization. The consignee shown on a bill of lading is also not automatically the IOR.
What Is a US Customs Bond?
A Customs Bond is not cargo insurance and it is not a deposit that eliminates importer liability. It is a financial guarantee involving the importer or principal, a surety company and CBP.
If the bonded party fails to pay duties, taxes, fees or other valid amounts—or fails to meet a covered customs obligation—the surety may face a claim under the bond. The surety can then seek reimbursement from the importer under their agreement.
CBP generally requires a bond for commercial imports valued above US$2,500 and may require one for regulated goods even at a lower value. The exact entry and bond requirements should be confirmed with the licensed US customs broker.
Single-Entry Bond vs Continuous Bond
| Articolo | Single Transaction / Single-Entry Bond | Continuous Bond |
|---|---|---|
| Coverage | One specific import transaction | Multiple qualifying import transactions during its term, normally one year |
| Ideale per | Occasional or first-time importers | Frequent importers with regular shipments |
| Bond amount | Calculated for the individual entry and risk; additional requirements may apply | Common minimum is US$50,000; higher amounts may be required according to duties, taxes and fees |
| ISF use | A separate or specifically structured ISF bond arrangement may be needed | A properly active continuous bond can generally support regular entry and ISF activity |
| Administration | Arranged shipment by shipment | Simpler for repeated entries once active and sufficient |
| Main risk | Cost and paperwork accumulate across repeated shipments | Bond insufficiency, non-renewal or increased exposure if import activity grows |
The continuous bond amount is commonly based on a percentage of duties, taxes and fees paid over the relevant 12-month period, subject to CBP and surety requirements. Products involving antidumping or countervailing duties can create substantially higher bond exposure.
Ocean Freight and the ISF Bond
US-bound cargo arriving by ocean vessel is generally subject to Importer Security Filing, commonly called ISF or “10+2.” The required importer data must generally be transmitted no later than 24 hours before the cargo is laden aboard the vessel destined for the United States.
Identify ISF Importer
Confirm which party is responsible for the filing.
Collect Data
Obtain seller, buyer, manufacturer, consignee, HTS and routing details.
Confirm Bond
Verify that an appropriate continuous or single ISF arrangement is active.
File Before Loading
Submit within the required timeframe and correct changes when necessary.
Match Entry Data
Keep ISF, B/L, invoice and customs entry information consistent.
How IOR and Bond Work in DDP Shipping
Under DDP, the seller assumes extensive transport and import responsibilities under the sales term. But the Incoterm itself does not override US customs law or automatically qualify the seller as the IOR.
A compliant US DDP plan should answer all of the following before booking:
Who Is the IOR?
Record the exact legal name, address and importer identification number.
Whose Bond Is Used?
Confirm that the bond is active, sufficient and connected to the actual importer.
Who Signs the POA?
The customs broker needs authorization from the responsible party.
Who Files ISF?
Allocate data collection, filing, amendments and timing responsibility.
Who Pays Duty?
Define funding, antidumping exposure, additional assessments and excluded charges.
Who Controls Compliance?
Confirm HTS, value, origin, marking, agency approvals and recordkeeping.
BRF Logistics can coordinate China factory pickup, trasporto marittimo, documentation and consegna porta a porta. The customs-entry structure must still be legally workable for the actual product and importer.
Practical Example: China to Los Angeles
Shipment: 1 × 40HQ of commercial fitness equipment
Percorso: Qingdao → Los Angeles → US warehouse
Servizio: Ocean freight plus customs and truck delivery coordination
A normal buyer-controlled structure could look like this:
- The US customer acts as Importer of Record.
- The customer’s EIN or CBP-assigned importer number is used.
- The IOR has an active continuous bond or arranges an appropriate single-entry bond.
- The licensed customs broker receives a valid Power of Attorney.
- The ISF filing is completed before the loading deadline.
- BRF coordinates pickup, booking, export customs, ocean transport and destination logistics within the agreed scope.
If DDP is requested and the US customer refuses to act as IOR, the seller must establish a lawful alternative before shipment. An unrelated importer number should never be borrowed merely to make the entry go through.
Common IOR and Customs Bond Mistakes
| Mistake | Why it creates risk | Better practice |
|---|---|---|
| Assuming the consignee is automatically the IOR | Consignee and importer roles can differ | Obtain written confirmation and broker authorization |
| Using a US company’s EIN without permission | Creates unauthorized customs activity and serious liability | Use only a knowledgeable, eligible and authorized importer |
| Believing the customs broker becomes the IOR | A broker acts as an agent and does not automatically replace the importer | Keep the IOR’s responsibilities and data controls clear |
| Treating a bond as cargo insurance | The two products protect different interests | Arrange customs security and cargo insurance separately |
| Waiting until arrival to find an IOR | ISF, entry, POA and bond arrangements may already be overdue | Complete importer onboarding before origin loading |
| Underestimating AD/CVD exposure | Final duties and bond requirements may be far above ordinary rates | Screen products and origins before purchase and booking |
| Mismatch between ISF, B/L and entry | Inconsistent parties or cargo data can trigger questions and delays | Use one verified document set and update changes promptly |

Domande frequenti
Is the consignee always the Importer of Record?
No. The consignee, notify party, buyer and IOR may be the same company, but they can also be different. The customs-entry structure must identify the eligible and authorized IOR.
Can a Chinese seller act as IOR in the United States?
Potentially, through an appropriate non-resident importer structure, but this requires importer registration, a US agent, Customs Bond, broker authorization and careful review of customs, product and tax obligations. It is not created automatically by choosing DDP.
Is a Customs Bond refundable?
A bond is a guarantee, not the same as a cash deposit. The importer pays a premium or fee to obtain it. Commercial terms, collateral and cancellation conditions depend on the surety and bond arrangement.
How much is a continuous Customs Bond?
The common minimum bond limit is US$50,000, while higher limits may be required based on duties, taxes, fees and import risk. The amount of the bond is not the same as the premium paid to purchase it.
Does a continuous bond cover ISF?
A properly active continuous import bond can generally support ISF filings, but the filer and broker should verify bond activity and sufficiency before the ocean loading deadline.
Can BRF provide US customs clearance and door delivery?
BRF Logistics can coordinate US customs-broker and final-delivery services as part of an agreed shipment plan. Cargo, importer, Bond, product compliance and destination requirements must be reviewed before booking.
