Regional Variations — IOR Rules in US vs EU vs UK
View Key Regional Differences
| Region | Requirements | Practical Impact |
|---|---|---|
| United States | Any U.S. entity with EIN may act as IOR; foreign companies must appoint an agent or use a U.S. importer. | Most cross-border e-commerce sellers use DDP freight forwarders or a 3PL with customs expertise. |
| European Union (EU) | Non-EU sellers cannot serve as IOR; must appoint an EU-based legal entity. | Common for brands to use IOR + EPR-compliant partners for electronics, apparel, cosmetics. |
| United Kingdom (UK) | Requires a GB-based entity to act as IOR. | Post-Brexit shipments often require separate IOR entities for EU and UK. |

Maxwell Anderson, Editor-in-Chief & Data Director, WinsBS Research:
“Across our 2025 inbound dataset, IOR errors were the #1 cause of customs holds for cross-border e-commerce brands. Misclassified HTS codes, undervaluation, and missing PGA documents were responsible for 64% of detentions. Brands operating without a U.S.-based compliance partner faced an average of 5–12 days delay per hold.”
Proper IOR strategy depends on product category, PGAs, and Incoterms. For DDP shipments, freight forwarders may act as the filing agent, but the brand is still liable for mis-declarations in many cases.

Importer of Record FAQ — Common Questions
Can a Chinese company be the IOR for U.S. shipments?
No. A foreign company cannot directly serve as a U.S. IOR unless it establishes a U.S. entity or appoints a legally authorized agent. Most cross-border e-commerce brands use a U.S.-based importer, customs broker, or DDP partner.
Is the IOR the same as the consignee?
Not necessarily. The consignee is the receiving party; the IOR is the legal compliance party. They may or may not be the same entity.
Who should NOT act as the IOR?
Entities without compliance staff, those unfamiliar with HTS/PGA rules, or sellers unwilling to assume financial and legal liability for customs entries. IOR responsibility carries significant penalties if errors occur.
Need Help with U.S. Inbound Compliance & IOR Planning?
Most customs delays originate from incorrect IOR setup, misclassified HTS codes, or missing PGA documents. WinsBS supports U.S. inbound shipments with compliance checks, document reviews, and 3PL receiving workflows to ensure smooth delivery.
