Key takeaways
- Grana Padano is the highest-volume Italian PDO cheese by export, with around 1.5 million wheels shipped in the first seven months of 2024.
- It is made across the Po valley, in Piedmont, Lombardy, Veneto, Trentino and part of Emilia-Romagna, which is a far wider zone than the five provinces Parmigiano Reggiano is limited to.
- The minimum ageing is 9 months, against 12 for Parmigiano Reggiano, and the three commercial grades are 9 to 16 months, Oltre 16 Mesi, and Riserva at over 20 months.
- Two production rules differ and both matter to a buyer: cows may be fed silage, and lysozyme may be added to the vat. Lysozyme is egg-derived, and egg is a major allergen that must be declared on a US label.
- Wheels run 24 to 40 kg, smaller than a Parmigiano Reggiano wheel, and the growth in the category is in grated and shaved formats rather than whole wheels.
- Grana Padano is usually the correct commercial answer for a mainstream banner, and Parmigiano Reggiano for a specialty counter. Choosing the wrong one is how a hard cheese listing fails.
Grana Padano Is Not a Cheaper Parmigiano Reggiano
Most American buyers can describe Parmigiano Reggiano and very few can describe Grana Padano, so the second cheese gets sold as a discount version of the first. That framing loses money, because it invites the shopper to treat the price gap as a quality gap and nothing else.
They are two separate PDO cheeses with separate rules. The price difference is a consequence of those rules, not a discount. Once you can say what the rules are, the cheaper cheese stops being the compromise on the shelf and starts being the right cheese for a particular shopper.

The Rules That Actually Differ
This is the comparison to give your own sales team, because it is the one a buyer will ask about:
| Grana Padano PDO | Parmigiano Reggiano PDO | |
|---|---|---|
| Production zone | The Po valley, across Piedmont, Lombardy, Veneto, Trentino and part of Emilia-Romagna | Parma, Reggio Emilia, Modena, part of Bologna and part of Mantua |
| Minimum ageing | 9 months | 12 months |
| Silage in the cattle feed | Permitted | Not permitted |
| Lysozyme in the vat | Permitted | Not permitted |
| Wheel weight | 24 to 40 kg | Around 40 kg |
| Typical channel | Everyday and mainstream retail, grated lines, foodservice | Deli counter, specialty retail, gifting |
The Lysozyme Question, and Why Your Label Team Will Ask It
Lysozyme is added to the vat in Grana Padano production to stop the cheese blowing during ripening. It is derived from egg white, and egg is one of the major allergens that has to be declared on a United States label.
This is not a food safety problem and it is not a reason to avoid the cheese. It is a reason to fix the artwork before the production run rather than after the container sails. Ask the dairy whether lysozyme is used, get the answer in writing on the specification sheet, and make sure your label reflects it. A buyer who discovers this at the port has a relabelling job on their hands.
It is also the honest answer to a shopper question you will eventually get, which is why two cheeses that look almost identical are made differently.
Which Grade Should You Buy?
Grana Padano is sold in three official ageing grades, and the grade decides the channel far more than the brand does:
| Grade | Character | Where it sells |
|---|---|---|
| 9 to 16 months | Milder, still slightly elastic, easy to portion and to grate | Everyday retail, grated and shaved lines, foodservice recipes |
| Oltre 16 Mesi | Crumblier, more pronounced, closer to what a shopper expects from a hard Italian cheese | Premium retail wedges, deli counters |
| Riserva, over 20 months | Grainy, crumbly, long finish | Specialty retail and cheese boards, smaller volumes |
Most importers should build the programme on the first two grades. Riserva is a range-completing line, not a volume driver.
How the Consortium Marks a Wheel
Ageing runs from a minimum of nine months, and the inspection happens at the end of it. A wheel that passes receives the fire-branded mark that certifies it as Grana Padano PDO. A wheel that fails has the diamond-shaped rind lozenges struck through with X marks, so it can no longer be sold under the name.
If you buy cut product rather than whole wheels, ask for the lot documentation that ties the cut back to a marked wheel. That paperwork is what your own customers’ compliance teams will ask for.
Formats, and Where the Growth Is
The reference format is the whole wheel at 24 to 40 kg, cut down into halves, quarters and smaller pieces for a deli to open and portion. Retail wedges are vacuum packed at fixed weights. Grated and shaved packs serve foodservice and travel best when the pack is nitrogen flushed.
The commercial point is that the growth in this category is in the grated and shaved formats rather than in whole wheels, and grated hard cheese exports have been rising faster in value than in volume. If you are building a Grana Padano programme for a mainstream banner, the grated line is probably the volume, and the wedge is the credibility.
Every cut stage costs yield, so a wedge programme will always price higher per kilo than wheels. This is a chilled product and it ships in a reefer container alongside other chilled Italian lines. If you are building a first container, our guide to mixed pallets and freight cost explains why combining hard cheese with cured meats and olive oil brings the logistics cost per kilo down.
Importing Grana Padano into the USA
Raw-milk cheese may be imported into the United States when it has been aged at least 60 days. Grana Padano is aged a minimum of nine months, so the ageing rule is not the obstacle. The rest is the standard food import sequence: the producing dairy holds an FDA food facility registration, you as the importer meet your FSVP obligations, Prior Notice is filed before arrival, and a licensed customs broker files the entry. We set that sequence out in full in our guide to importing food from Italy to the USA.
The label is where this cheese differs from the others. Alongside the usual English label, Nutrition Facts panel and country of origin, you need the allergen declaration to match what is actually in the vat, which brings you back to the lysozyme question above.
What Documents Come With the Shipment
A Grana Padano shipment travels with a commercial invoice and packing list, a certificate of origin, the health certificate the destination requires, the producer’s specification sheets with ageing, lot and allergen data, and the PDO documentation tying the goods to marked wheels. We prepare the origin and food-safety paperwork before the container sails, so your broker is not waiting on Italy while the box sits at the port.
Ordering at a Realistic Volume
Our minimum is one pallet, mixed across products and producers. For a buyer testing Grana Padano that usually means a quantity of the grade your channel needs, a grated or shaved reference to see how the format performs, and other chilled or ambient lines to fill the pallet. We consolidate from several producers into a single shipment with one set of export documents.
If the reorder is what worries you rather than the first order, that is the right instinct, and we cover it in the minimum order quantity guide.

Frequently asked questions
What is the difference between Grana Padano and Parmigiano Reggiano?
They are two separate PDO cheeses. Grana Padano is made across a much wider zone in the Po valley, has a minimum ageing of 9 months against 12, permits silage in the cattle feed, and permits lysozyme in the vat. Parmigiano Reggiano permits neither.
How long is Grana Padano aged?
A minimum of nine months. The three commercial grades are 9 to 16 months, Oltre 16 Mesi, and Riserva at over 20 months.
Does Grana Padano contain lysozyme?
Lysozyme is permitted in Grana Padano production and is used to stop the cheese blowing during ripening. It is egg-derived, and egg is a major allergen that must be declared on a US label, so ask the dairy for the answer in writing on the specification sheet before the artwork is printed.
Can Grana Padano be imported into the United States?
Yes. Raw-milk cheese may be imported when it has been aged at least 60 days, and Grana Padano is aged a minimum of nine months.
Which grade sells best at retail?
The 9 to 16 month grade suits everyday retail, grated lines and foodservice, and Oltre 16 Mesi suits premium wedges and deli counters. Riserva is a range-completing line rather than a volume driver.
How big is a Grana Padano wheel?
Between 24 and 40 kg, which is smaller than a Parmigiano Reggiano wheel at around 40 kg.
What is your minimum order for Grana Padano?
One pallet, mixed across products and producers, so you can take Grana Padano alongside other Italian lines at entry volume.
