Maxwell Anderson, Editor-in-Chief & Data Director, WinsBS Research:
“Across 2025 filings, 78% of customs delays originated from importer-provided errors, not broker mistakes. The top three issues were incorrect HTS codes, unsupported valuations, and missing PGA documents. Brokers transmit data — they don’t validate it — so the importer’s compliance posture drives the risk.”
For e-commerce brands importing from China, the role of the customs broker depends heavily on accuracy of supplier documents, Incoterms, and IOR readiness (especially under UFLPA).

Customs Broker FAQ — Common Questions
Do customs brokers take responsibility for HTS codes?
No. They provide recommendations, but the IOR is legally responsible for classification accuracy.
Can a broker act as the Importer of Record?
No. Brokers cannot serve as the IOR. They can only file entries on behalf of the IOR using a Power of Attorney (POA).
Do I need a customs broker for DDP shipments?
Technically no — your forwarder handles the clearance. But if documents are wrong, the liability still rests with the importer or shipper of record.
Need Help with U.S. Customs Clearance & Compliance?
Most import delays come from incorrect classification, missing FDA/FCC files, or faulty supplier documents. WinsBS supports your U.S. inbound workflow with document reviews, compliance checks, and 3PL receiving — reducing CBP exam risks.
