Do You Need a 3A Certified Cream Separator to Sell Dairy Products in the U.S.?

If you're a dairy farmer or creamery owner thinking about separating cream commercially, you've probably already noticed there's a wide range of cream separators on the market — from $300 home units to $5,000 commercial machines. So what's the real difference? And do you actually need a 3A certified cream separator to sell dairy products legally in the United States?
The short answer is yes — if you're selling Grade A milk or cream commercially, 3A certification isn't optional. Here's what you need to know before you buy.
What Is 3A Certification and Why Does It Matter?
3A Sanitary Standards are a set of equipment design requirements developed jointly by dairy equipment manufacturers, regulatory sanitarians, and the dairy industry. They define exactly how dairy processing equipment must be built — the materials used, the surface finishes, the weld quality, the drainage design — to ensure milk contact surfaces can be properly cleaned and sanitized.
When a cream separator carries the 3A symbol, it means the equipment has been independently verified to meet those standards. It's not a marketing claim — it's a third-party certification that your state dairy inspector will look for when they walk into your facility.
The Pasteurized Milk Ordinance (PMO), which governs Grade A dairy operations across all 50 U.S. states, requires that all equipment used in the processing and handling of Grade A milk meet 3A Sanitary Standards. This is a federal standard adopted at the state level — which means it applies to every commercial dairy operation in the country, from Vermont to California.
Can You Use a Non-3A Cream Separator Commercially?
This is where many small dairy producers get into trouble.
There are many cream separators on the market — including popular models from European brands — that are well-built and reliable. Some are sold with claims that they are suitable for "commercial use." But unless they carry the 3A symbol and appear on the 3-A SSI accepted equipment list, they do not meet PMO requirements for Grade A dairy operations.
Some manufacturers are upfront about this. Others aren't.
The risk is real. If a state dairy inspector visits your facility and finds non-compliant equipment in your cream separation process, you can be required to remove it, shut down that part of your operation, or, in serious cases, lose your Grade A permit entirely. No dairy producer wants to be in that position — especially after investing in equipment, building out a facility, and building a customer base.
If you're producing cream for personal use or selling at a farmers market in a state that allows cottage food sales without Grade A licensing, you may have more flexibility. But the moment you're selling commercially — to grocery stores, restaurants, distributors, or any regulated retail channel — you need compliant equipment.
What Makes a Cream Separator 3A Certified?
Not every cream separator can achieve 3A certification. It requires specific design and construction standards including:
All milk contact surfaces are made from 304 or 316 stainless steel — no aluminum, no plastic components in contact with milk
Surface finish of Ra 32 microinches or smoother on all milk contact surfaces — this prevents bacteria from hiding in surface scratches
Full drainability — no areas where milk can pool and become a breeding ground for bacteria
Cleanability — all parts must be accessible for cleaning, either manually or through a CIP (Clean-In-Place) system
No crevices or threads in milk contact areas that could harbor contamination
Many lower-cost separators use food-grade aluminum or plastic components in the bowl and disc stack — materials that simply cannot meet 3A surface finish requirements. That's not a flaw in those machines for what they're designed to do. It's just the reality of what 3A certification requires.
Tessa's 3A Certified Cream Separators — Built for Commercial Dairy Operations
Tessa Dairy Machinery's cream separator line — the TS-100, TS-200, and TS-300 — are fully certified to 3A Sanitary Standards and compliant with the U.S. Pasteurized Milk Ordinance (PMO) and Canadian CSA requirements.
TS-100 — processes 100 gallons (350 liters) of milk per hour. Ideal for small commercial creameries, farmstead operations, and goat milk producers processing up to 800 gallons per shift.
TS-200 — processes 200 gallons (750 liters) per hour. The right fit for growing dairy operations processing 1,500–2,000 gallons per shift.
TS-300 — processes 300 gallons (1,100 liters) per hour. Built for larger commercial creameries and dairy plants with high-volume cream separation needs.
All three models are built from 304 stainless steel throughout — including the bowl, disc stack, and all milk contact surfaces. Every unit ships with full 3A certification documentation, so you have everything you need when your state dairy inspector comes calling.
They're also designed to integrate directly into a complete dairy processing line — connecting to your batch pasteurizer, storage tanks, and packaging equipment without adapters or workarounds.

Is This the Right Cream Separator for You?
Tessa's cream separators are built for commercial dairy producers who need certified, inspectable equipment. If that's you, here's how to figure out which model fits your operation:
Choose the TS-100 if:
You're processing up to 800 gallons of milk per shift
You're a farmstead creamery, goat dairy, or small artisan producer
You're just entering commercial cream production and want a reliable starting point
Choose the TS-200 if:
You're processing 800–2,000 gallons per shift
You're expanding an existing operation and need more throughput
You produce cream, butter, and other cream-based products at commercial scale
Choose the TS-300 if:
You're processing 2,000+ gallons per shift
You run a larger dairy plant or cooperative processing facility
You need continuous high-volume separation with minimal downtime

One More Thing Worth Knowing
Your cream separator doesn't operate in isolation. For a Grade A dairy operation, your entire processing line needs to meet PMO and 3A requirements — including your pasteurizer, storage tanks, and filling equipment. Buying a 3A certified cream separator is the right first step. Making sure everything connected to it is also compliant is what keeps your Grade A permit secure long term.
Tessa supplies complete PMO- and 3A-compliant dairy processing lines — from raw milk reception through to packaged finished product. If you want to make sure your entire operation is built right from the start, talk to our team about a complete processing line review.
The Bottom Line
If you're selling dairy products commercially in the United States, you need a 3A-certified cream separator. It's not a nice-to-have — it's a federal requirement under the Pasteurized Milk Ordinance that applies in every state.
The good news is that a properly certified commercial cream separator doesn't just keep you compliant — it's a better-built machine. All-stainless construction, cleanable surfaces, and reliable high-volume performance are features that pay for themselves in product quality and operational efficiency over time.
Tessa's TS-100, TS-200, and TS-300 cream separators are built to that standard. If you're ready to set up a compliant, commercial-grade cream separation operation, get in touch, and we'll help you get there.
