U.S. imports of bird eggs, in shell, preserved or cooked (HS 040790) totaled $574K in April 2026, traded with 4 countries.
Last updated: April 2026 dataPreserved or cooked in-shell bird eggs — including century eggs, salted eggs, and similar Asian-market preparations — are classified under a single line (0407900000) and enter the US as processed food products subject to FDA oversight, including prior notice and labeling requirements. China and Taiwan are the leading suppliers, reflecting the strong culinary tradition of preserved egg products in East Asian cuisine and the established export infrastructure in those markets. Unlike fresh eggs, preserved preparations may also trigger FDA scrutiny for additives such as lead compounds historically used in century-egg processing, making ingredient disclosure on import documentation particularly important. Importers should ensure that processing methods and ingredient lists comply with FDA food additive regulations before shipment.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Traditional century-egg production has historically used lead oxide or copper sulfate in the curing process. FDA may sample and test preserved egg shipments for heavy-metal contamination; products exceeding action levels can be refused entry. Importers should obtain certificates of analysis from suppliers confirming that processing methods comply with US food safety standards.
The preserved/cooked condition places these eggs in a different HTS heading (0407.90) than fresh eggs (0407.21 or 0407.29), and the applicable duty rates differ accordingly. Because duty rates can change and vary by specific line, importers should consult the current Harmonized Tariff Schedule or a licensed customs broker to confirm the applicable rate for their specific product.
