Food and beverage manufacturing is one of the largest and most consistent freight verticals in North America. Nearly every consumer packaged goods company, food manufacturer, ingredient supplier, and food distributor ships freight weekly or daily. Volume is recurring, the shipper base is broad, and the compliance requirements — while real — are learnable. The brokers who understand FSMA and food-grade carrier requirements operate in a market where most competitors are guessing.
What Makes Freight "Food-Grade"
Food-grade freight is any shipment of food, food ingredients, food packaging in contact with food, or animal feed that is subject to the FDA's contamination prevention requirements. The term gets used loosely in the industry — understanding the actual requirements helps you avoid both over-promising and under-delivering.
The core concern is cross-contamination: a trailer that previously hauled chemicals, pesticides, or other harmful substances retaining residue that transfers to a food shipment. The prevention framework involves:
- Prior cargo verification. The shipper is required to assess whether a carrier's equipment is appropriate for the food being transported. This includes asking about prior loads in the trailer — some food manufacturers maintain explicit "last three loads" requirements and will reject trailers that hauled certain commodities.
- Trailer cleaning and sanitization. Trailers must be clean and, where required by the food type, sanitized. A trailer that visually appears clean may still have residue from a prior non-food load. Food-grade carriers maintain wash records.
- Temperature control. For temperature-sensitive food (refrigerated or frozen), carriers must maintain specified temperature ranges throughout transport. For shelf-stable dry freight, temperature is less often a regulated issue, but trailer condition and cleanliness remain requirements.
- Pest control. Food-grade trailers must be maintained to prevent pest infestation. Brokers working produce or grain-adjacent food freight should verify pest control practices are in place.
The distinction that matters for brokers: not every dry van carrier is a food-grade carrier. A carrier who runs primarily industrial freight — chemicals, automotive parts, construction materials — and occasionally picks up food loads in between is not operating to food-grade standards. Your job is to put food-grade shippers with food-grade carriers.
The FSMA Sanitary Transportation Rule
The Food Safety Modernization Act (FSMA) was signed into law in 2011 and represents the most significant overhaul of FDA food safety authority in decades. The Sanitary Transportation of Human and Animal Food Rule (21 CFR Part 1, Subpart O), which became effective in 2017, directly addresses freight transportation.
Key provisions that affect how you work:
Shipper responsibilities. Shippers must specify to carriers the sanitary requirements for each shipment — temperature controls, trailer cleanliness standards, prior cargo restrictions. They must assess whether the carrier's equipment and practices can meet these requirements before tendering a load.
Carrier responsibilities. Carriers must comply with the shipper's specifications. They must maintain equipment in a sanitary condition, provide information about prior loads when requested, and implement temperature control as specified. Carriers must also train employees who handle food transportation.
Training requirements. Personnel at shippers and carriers who have responsibilities for food transportation sanitation must be trained on their obligations under the Rule. This training must be documented.
Who is covered. The rule covers shippers, loaders, carriers, and receivers involved in food transportation. Brokers are not explicitly named as a regulated party. However, brokers who arrange transportation that violates these requirements may face liability under agency or common carrier law, and any shipper operating under FSMA will hold you responsible for the compliance of the carriers you provide.
Small carrier exemption. Carriers with annual receipts under $25.5 million are exempt from the rule's carrier-side requirements, though shippers can still impose contractual compliance requirements on them.
For a broker, the practical implication is this: know the rule well enough to ask the right questions, source carriers who meet the requirements, and document your carrier vetting process.
Trailer Types and Food Applications
The food supply chain uses multiple trailer types depending on the product characteristics.
Dry van (food-grade): Shelf-stable packaged foods, dry ingredients (flour, sugar, starches), canned goods, beverage in ambient packaging, snack foods, confectionery. The trailer must be clean, free of prior cargo residue, and pest-free. This is the highest-volume category for food freight brokers.
Refrigerated (reefer): Fresh produce, dairy, meat, poultry, seafood, deli products, beverages requiring cold chain. The carrier must maintain shipper-specified temperatures throughout transport and document temperature data. Pre-cooling the trailer before loading is standard practice — many food-grade reefer loads require a pre-cool period before loading begins.
Frozen: Ice cream, frozen entrees, frozen vegetables, frozen meat. Typically requires -10°F to 0°F maintenance. More demanding than refrigerated both for equipment maintenance and liability if temperature excursion occurs.
Flatbed (limited food use): Large bulk bags (super sacks) of dry ingredients, grain and seed in certain configurations, some agricultural products. Less common than enclosed trailer types but present in the ingredient supply chain.
Bulk tanker (food-grade): Liquid ingredients — corn syrup, edible oils, liquid sugar, liquid eggs, juice. Tanker carriers serving food applications have sanitation requirements specific to tanker equipment, including clean-in-place (CIP) procedures and dedicated food-grade tanker fleets. This is a specialized sub-segment.
How to Vet Food-Grade Carriers
Standard carrier vetting (FMCSA safety score, insurance, operating authority) is necessary but not sufficient for food freight. Additional verification:
Trailer wash records. Food-grade carriers maintain wash certificates — documentation showing when and where a trailer was washed and what the prior cargo was. Major food manufacturers require trailers to arrive with a valid wash certificate. Ask carriers whether they maintain wash records and how current they are before booking a food load.
FSMA training documentation. Carriers covered under the Sanitary Transportation Rule are required to document employee training. A food-grade carrier should be able to confirm their training program exists and is current.
Prior cargo inquiry process. Ask how the carrier tracks prior loads in specific trailers. "We don't keep that information" is a red flag for a carrier claiming food-grade capability.
Pest control maintenance. Particularly relevant for produce, grain-adjacent, and warehouse distribution freight. Ask whether trailers are included in the carrier's pest control program.
Customer references in food. A carrier who regularly hauls food freight for grocery distributors, food manufacturers, or CPG companies has an established track record. Ask who their major food customers are.
FSMA compliance certification. Some carriers have pursued third-party FSMA compliance verification or food safety certifications (e.g., Safe Quality Food Institute certification). This is not required, but it's a positive indicator.

What Food Manufacturers Look For in a Broker
Food manufacturing logistics managers — particularly at mid-size and large CPG companies — have seen brokers who get fired before. They're evaluating whether you're a liability or an asset.
Compliance knowledge. A broker who knows what FSMA requires, what questions to ask carriers, and what documentation matters signals they're not going to create a contamination incident or a compliance violation. A broker who asks "what's FSMA?" in the first meeting signals the opposite.
Carrier documentation. Food manufacturers increasingly want to see carrier compliance documents before a load is booked, not after. Being able to provide wash certificates, insurance certificates, and FSMA training confirmation before the load picks up is the standard.
Communication on exceptions. Temperature excursions, damage, trailer problems — these get communicated immediately and directly. Food loads have quality implications beyond just late delivery. A temperature excursion on a reefer load can render an entire shipment unsaleable. The broker who communicates proactively on exceptions is the broker who keeps the account.
Consistency. Food manufacturers who find a broker with compliant carriers and good execution don't want to retrain a new broker. Consistency of carrier quality across loads is more valuable than optimizing any individual load rate.
Seasonality in Food Freight
Food freight has meaningful seasonal patterns that affect broker planning.
Holiday production runs (Q3/Q4): Consumer food manufacturers ramp production significantly for holiday-season CPG — packaged goods, confectionery, canned and jarred foods, beverage, snack foods. August through November is peak freight season for many food manufacturers. Carrier capacity can tighten significantly.
Produce season: Fresh produce follows growing seasons — different commodities peak at different times, but overall fresh produce freight peaks in summer, especially for domestic produce from California, Florida, and Texas. Refrigerated carrier capacity competes across food categories during produce season.
Ingredient supply patterns: Commodity ingredient procurement (sugar, oils, grains, flavorings) is influenced by harvest cycles, pricing, and manufacturer inventory strategies. Ingredient suppliers often see large volume moves tied to commodity price cycles that don't follow a standard calendar.
How to Get Into the Food Vertical
Food brokers and distributors are a more accessible entry point than direct-to-manufacturer. Food brokers (who sell food products, distinct from freight brokers) use freight regularly to move products between manufacturers and distributors. Distributors run high-frequency outbound lanes from DCs to retail customers.
Co-manufacturers (co-mans) produce food products under contract for branded CPG companies. They're mid-size facilities with substantial freight volume and often less sophisticated logistics operations than large CPG companies. They're more open to working with new-to-food brokers.
Ingredient suppliers — flour mills, sugar refiners, starch manufacturers, flavoring companies — are another entry point. Their freight is often dry van, food-grade, high-frequency, and national in reach.
For direct CPG manufacturers (large brands), the path is usually through a track record with smaller food accounts first, or through a referral. Like automotive, large food companies are risk-averse about adding new broker relationships and expect proof of capability before the conversation happens.
Frequently Asked Questions
What does food-grade trailer actually mean?
In practice, a food-grade trailer is one that is maintained clean, free from prior cargo residue that could contaminate food, pest-free, and in good structural condition (no holes, no moisture ingress). There's no single federal certification called "food-grade trailer" — it's a standard defined by practice and FSMA requirements. A carrier who claims food-grade capability should be able to demonstrate wash records, a process for assessing prior cargo, and a maintenance program that keeps trailers in appropriate condition.
Does FSMA apply to dry freight?
Yes. The Sanitary Transportation Rule applies to all food transportation — dry, refrigerated, and frozen. The specific requirements vary by food type (temperature controls are obviously more critical for perishables), but the core obligations around sanitation, prior cargo assessment, and training apply across the board. A broker moving shelf-stable packaged goods in dry van is operating in FSMA-regulated freight just as much as a broker moving refrigerated dairy.
How do I verify a carrier is food-grade compliant?
Ask directly and verify the answers. The checklist above covers the key items. Beyond that, check whether the carrier's major customers are food companies — a carrier who regularly serves major food distributors or CPG manufacturers has practical experience that you can't easily fake. Carriers who haven't thought about FSMA, don't maintain wash records, or can't tell you about their prior cargo tracking system are telling you where they stand.
Do I need special certifications to broker food freight?
No federal certification is required for brokers to arrange food transportation. Standard broker authority (MC number, surety bond) is sufficient from a licensing standpoint. Some brokers pursue food safety training certifications (e.g., PCQI — Preventive Controls Qualified Individual — training, though this is primarily for food manufacturers) to demonstrate knowledge. The more practical approach is investing in regulatory knowledge and being able to demonstrate it in conversations with food manufacturers.
What happens if a carrier violates food-grade requirements on my load?
The consequences depend on the nature of the violation and the outcome. If a non-compliant trailer causes a food safety incident — contamination that results in a recall, consumer illness, or FDA enforcement action — the liability chain extends to everyone who arranged the shipment, including the broker. Even absent a safety incident, a food manufacturer whose requirements were not met (wrong carrier, missing documentation, temperature excursion) will typically back-charge for any resulting product loss and remove the broker from their approved carrier list. Document your carrier vetting process and maintain evidence that you verified compliance before each load. If an incident does occur, your documentation of due diligence is your best protection.
