Kosher for Passover Ingredients: What 'Kosher for Passover' Means for Manufacturers

A year-round kosher certificate does not make a product kosher for Passover. Passover (Pesach) certification, the "P" alongside an agency symbol, is a separate, stricter standard.

For an ingredient buyer it lands hardest on a few specific categories. If you produce a Passover product line, plan the sourcing months ahead, because certified material is seasonal and tight. For the base symbols, see how to read kosher symbols.

Two rules drive everything: chametz and kitniyot

Chametz is leavened grain, including wheat, barley, rye, oats, and spelt, and any derivative. It is strictly prohibited on Passover. This is why grain alcohol is the classic problem. Vanilla and other flavor extracts carried in ethanol are often chametz (see is vanillin halal and kosher). It is also why certain enzyme and fermentation products made on grain substrates fall out of compliance.

Kitniyot is the broader category, including legumes, corn, rice, and related crops, avoided by Ashkenazi communities during Passover. This is the rule that surprises formulators, because it sweeps in some of the most common industrial ingredients:

• Corn-derived everything. Corn syrup, dextrose, most citric acid, many fermentation products grown on corn substrate, maltodextrin, and corn-derived erythritol and sorbitol.
• Soy. Soy Lecithin and soy protein are kitniyot, which is why Sunflower Lecithin is the Passover-friendly emulsifier.
• Rice and legume derivatives.

Where common ingredients stand for Passover

• Citric Acid Anhydrous. Usually fermented on corn (kitniyot) and a frequent Passover exclusion. Passover-certified citric acid exists but is a specific, seasonal grade.
• Sweeteners. Sucralose and Acesulfame Potassium themselves are typically fine, but corn-derived bulking agents and carriers attached to them are the issue. Polyols and erythritol depend on substrate.
• Emulsifiers. Sunflower Lecithin over soy. See soy vs sunflower vs egg lecithin.
• Flavors. Powder or glycerin/PG-carried, not grain-ethanol extracts.
• Hydrocolloids. Seaweed-derived (Agar Agar, Carrageenan) are generally fine. Fermentation gums like Xanthan Gum depend on the substrate.

Choose by what you produce

• If you produce a seasonal Passover line, build a separate bill of materials. Swap corn-substrate ingredients for cane or other permitted substrates, soy lecithin for sunflower, and ethanol flavors for powder or glycerin-carried.
• If your finished products use citric acid, confirm whether a Passover-certified (non-corn) grade is available for your run, and order it early.
• If you supply Ashkenazi communities, kitniyot matters even when the ingredient is otherwise kosher. Check substrate, not just the year-round certificate.

What to verify

• A Passover-specific certificate (with "P") for the exact production run, not the year-round certificate.
• Fermentation/bulking substrate (corn versus cane versus other), because kitniyot status follows the substrate.
• Carrier solvents in liquids, with no grain ethanol.
• Lead time. Passover material is produced in dedicated, supervised runs. Order early.

We can source Passover-certified grades of common additives and confirm substrate and carrier per lot. If you run a seasonal Pesach line, send us your products and application and your deadline well ahead. Passover stock is the tightest window in the kosher calendar.
