US Produce Import Regulations 101 — What Every Importer Needs to Know

Every truckload of fresh produce crossing into the United States is subject to oversight from at least three federal agencies: the Food and Drug Administration (FDA), the US Department of Agriculture (USDA), and Customs and Border Protection (CBP). If you're importing produce from Mexico or anywhere in Latin America, understanding how these agencies interact — and what they require from you as the importer of record — is not optional. It's the cost of doing business.

This guide covers the core regulatory requirements that every US produce importer needs to know. It's not legal advice, but it is the practical foundation that keeps shipments moving and keeps your company off the FDA's detention list.

FDA Requirements — Prior Notice and FSMA

The FDA regulates the safety of all food entering the United States, including fresh produce. Two requirements matter most for importers:

Prior Notice of Imported Food. Before any food shipment arrives at a US port of entry, the importer (or their customs broker) must submit a Prior Notice to FDA through the ACE system. This notice includes the product description, manufacturer/shipper, country of origin, anticipated arrival port, and importer of record. For land border crossings from Mexico, Prior Notice must be submitted no later than 2 hours before arrival. For ocean shipments, it's 8 hours.

If Prior Notice is not filed or is filed incorrectly, FDA can refuse entry and hold the shipment at the border. This is one of the most common causes of delays at land crossings, and it's entirely preventable.

Foreign Supplier Verification Program (FSVP). Under the Food Safety Modernization Act (FSMA), every US importer of food is required to verify that their foreign suppliers are producing food in compliance with US safety standards. In practical terms, this means:

• You must identify hazards associated with the food you're importing.
• You must evaluate your supplier's food safety practices (certifications, audit reports, testing records).
• You must conduct ongoing supplier verification activities (periodic audits, sampling, or review of the supplier's food safety records).
• You must maintain written FSVP documentation for each supplier and each food product.

FDA inspectors can and do show up at importer facilities to review FSVP records. Failure to maintain adequate documentation can result in warning letters, import alerts, or detention without physical examination (DWPE) — meaning your future shipments get automatically held.

The bottom line: if your Mexican supplier has a GlobalG.A.P. or PRIMUS GFS certification and you've documented your verification, you're in good shape. If you're importing from a supplier with no third-party audit and no food safety plan, you're exposed.

USDA Inspection at the Border

The USDA's role at the border involves two separate agencies with different mandates:

APHIS (Animal and Plant Health Inspection Service) inspects incoming produce for pests and plant diseases. Every shipment of fresh fruits and vegetables is subject to APHIS inspection, though not every load is physically opened. APHIS maintains a risk-based inspection protocol — products from regions with known pest concerns get inspected more frequently.

If APHIS finds a quarantine pest (such as fruit fly larvae in mangoes, or certain moth species in leafy greens), the shipment can be treated (fumigation, cold treatment), re-exported, or destroyed. There is no appeal. For certain commodities like Hass avocados from Michoacan, APHIS maintains a pre-clearance program where inspections happen at the packing facility in Mexico before the truck even reaches the border.

AMS (Agricultural Marketing Service) handles quality grading. Federal-state inspection at the border verifies that produce meets the grade standard declared on the invoice (e.g., US No. 1 for tomatoes). Grade inspection is not always mandatory, but buyers frequently require it, and some commodities have regulatory minimum grade requirements for import.

When a shipment fails grade inspection, the importer has several options: accept a lower grade designation (and usually a lower price), recondition the load (sort out defective fruit), or file a claim with the shipper. This is where having a clear supply agreement with your Mexican supplier matters.

CBP Entry Process

Customs and Border Protection handles the actual importation paperwork and duty collection. For fresh produce from Mexico, most shipments enter under NAFTA/USMCA duty-free provisions, but the administrative requirements still apply:

Required documents for every entry:

• Commercial invoice (showing shipper, consignee, product, quantity, unit value)
• Packing list
• Bill of lading or truck manifest
• Customs entry form (CBP Form 3461 for immediate delivery, or 7501 for formal entry)
• Phytosanitary certificate from Mexico's SENASICA (required for most fresh produce)
• FDA Prior Notice confirmation

Customs bond. Any importer bringing commercial goods into the US must have a customs bond. For frequent importers, a continuous bond (annual) is standard. The bond amount is typically set at 10% of the prior year's total duties, taxes, and fees — though for duty-free produce under USMCA, the bond minimum still applies.

ACE filing. All entry data is filed electronically through CBP's Automated Commercial Environment. Most importers use a licensed customs broker for this. The broker files the entry, pays any duties, and handles communication with CBP on your behalf.

Turnaround time: At major produce border crossings like McAllen-Hidalgo and Nogales-Mariposa, a clean shipment with pre-filed paperwork can clear in 1--3 hours. A shipment selected for APHIS inspection or FDA exam can take 4--8 hours or more.

Common Compliance Issues

These are the problems that actually hold up produce shipments at the border:

Pesticide residue violations. FDA and EPA jointly regulate pesticide tolerances for imported produce. If a sample tests above the EPA tolerance for any pesticide, the shipment is refused. Certain Mexican-origin products (leafy greens, peppers, herbs) have historically higher violation rates. The best defense is working with suppliers who conduct pre-shipment residue testing.

Labeling deficiencies. All retail produce entering the US must comply with FDA labeling requirements, including country of origin. Wholesale produce must have proper case markings. Mislabeled product or missing country-of-origin declarations can trigger holds.

Country of Origin Labeling (COOL). Under the Perishable Agricultural Commodities Act (PACA) and USDA COOL regulations, fresh fruits and vegetables must be labeled with their country of origin at the retail level. For produce imported from Mexico, this means "Product of Mexico" must appear on the label or PLU sticker. Enforcement has increased in recent years.

Incorrect HS codes. Filing under the wrong Harmonized System tariff code can trigger delays, audits, or penalty assessments. Fresh tomatoes, peppers, and cucumbers have notoriously specific HS code classifications that vary by variety and preparation.

How Trade Intelligence Helps Compliance

Regulatory compliance isn't just about your own paperwork. It's about knowing your supply chain:

• Supplier track record matters. A Mexican shipper with a history of FDA import refusals or APHIS detentions is a higher risk to your operation. ProduceTradeIQ's produce shipment records let you see which shippers are actively exporting and at what volume — high-volume, consistent shippers tend to have better compliance infrastructure.

• Benchmark against industry patterns. ProduceTradeIQ's trade analytics show aggregate import patterns by product, port, and season. This helps you understand what's normal for your commodity and flag anomalies in your own supply chain.

• Documentation support. Shipment-level data from CBP records can supplement your FSVP documentation, providing evidence of your supplier's export history and trade activity.

Compliance isn't glamorous, but it's the foundation of every successful import operation. The importers who treat it as a competitive advantage — not just a cost — are the ones who keep their supply chains running when others get held at the border.
