Frequently Asked Questions

What regulatory compliance documents are required for importing artificial hip and knee joints (HTS 902131) into the United States?

Shipments of artificial hip and knee joints must be accompanied by a U.S. Food and Drug Administration (FDA) Premarket Approval (PMA) or 510(k) clearance number for the specific device model. The importer of record must also provide the FDA's required device listing number and, upon entry, submit an FDA Form 2877. These medical devices are subject to detention without physical examination if proper FDA documentation is not presented to U.S. Customs and Border Protection.

What are the critical packaging requirements for shipping artificial hip and knee joints (HTS 902131) to ensure sterility and prevent damage?

Artificial joints must be shipped in their original, sealed sterile packaging, which must then be placed within a secondary protective container to prevent crushing or puncture. The outer shipping box must be clearly marked with "Medical Device," "Fragile," and "Keep Dry" labels to ensure proper handling and maintain the product's sterile barrier integrity.

Common Classification Mistakes

A frequent error is classifying orthopedic implants for the knee and hip together under 9021.31. It is critical to separate hip joint prostheses (9021.31.0030) from knee joint prostheses (9021.31.0060) as they have different statistical suffixes and duty rates. Another common mistake is incorrectly classifying the individual components (e.g., femoral stems, tibial trays, or polyethylene inserts) under this code; unmounted or unassembled components may be classified elsewhere, such as in 9021.90 as parts. Additionally, ensure the device is for human orthopedics; veterinary implants for animals are classified in a different chapter (e.g., 3006 or 9021.10).
