Market
Fresh red onion in Mexico is produced within the broader dry onion sector and is shipped both for domestic consumption and for export programs. UN Comtrade data (WITS, HS 070310) indicates Mexico’s exports of fresh/chilled onions and shallots are overwhelmingly oriented to the United States, making cross-border truck logistics a primary commercial lever. For U.S.-bound red onions, USDA AMS Section 8e import requirements set minimum grade, size, and maturity (curing) thresholds that must be met to avoid entry delays or refusal. When destination markets require phytosanitary certification, exporters must obtain a SENASICA-issued International Phytosanitary Certificate after meeting the importing country’s requirements.

Risks
Regulatory Compliance HighU.S.-bound red onion shipments that fail USDA AMS Section 8e minimum grade, size, and maturity requirements (or are not handled under the required import inspection workflow) can be delayed, rejected, or prevented from entering the U.S. market during the applicable date windows.Build a U.S. Section 8e compliance checklist into pre-shipment QC (grade/size/maturity), keep inspection documentation aligned with entry filings, and plan buffers for border inspection/holds.
Logistics MediumCross-border truck congestion, inspection surges, and fuel-rate volatility can materially increase delivered cost and shrink for fresh onions shipped from Mexico to the United States.Use disciplined curing and dry loading practices, build schedule buffers around peak border periods, and negotiate freight/delay terms that allocate border-hold risk clearly.
Phytosanitary MediumFailure to meet destination-country phytosanitary requirements (including obtaining a SENASICA-issued International Phytosanitary Certificate when required) can trigger shipment refusal or market suspension.Verify destination requirements before contracting, use authorized inspection units, and maintain documented pest management and pre-export inspection records aligned to destination requirements.
Food Safety MediumU.S. FSMA-driven buyer requirements and enforcement actions can create market-access risk for export-oriented Mexican horticultural suppliers if preventive controls and supporting documentation are insufficient.Maintain FSMA-aligned food safety programs appropriate to the operation (including documented sanitation and traceability practices) and keep audit-ready records for U.S. buyers/importers.
FAQ
What quality requirements apply to red onions imported from Mexico into the United States?U.S. onion imports are subject to USDA AMS Section 8e requirements. For the June 5–March 9 window, red onions must be U.S. No. 2 grade or better, at least 1 1/2 inches in minimum diameter, and at least “moderately cured.”
When do Mexican exporters need an International Phytosanitary Certificate for fresh onions?SENASICA indicates exporters must first confirm the importing country’s phytosanitary requirements. When the destination requires it, an International Phytosanitary Certificate (Certificado Fitosanitario Internacional) is issued by SENASICA after the exporter demonstrates compliance with those destination requirements.
Which export market dominates Mexico’s trade in fresh/chilled onions and shallots?UN Comtrade partner data (via the World Bank WITS tool, HS 070310) shows the United States is Mexico’s dominant destination for exports of onions and shallots, fresh or chilled, with smaller reported volumes to partners such as Guatemala, El Salvador, Belize, Spain, and Canada.
