Kosher certification ensures that products meet the strict dietary requirements of Jewish law. For a product to be Kosher certified, every ingredient, food additive, and processing aid used in its production must also be Kosher certified or approved.
At TE ISO SOLUTIONS, we help businesses navigate the complexities of Kosher certification, opening doors to new markets and building trust with Jewish consumers worldwide.
Common Misconceptions
The term “Kosher” is frequently misunderstood as referring only to the slaughter of meat (shechita). While the preparation of Kosher meat is important and governed by separate regulatory authorities, Kosher certification applies to a wide range of products and involves many additional requirements.
Core Principles of Kosher
Separation of Meat and Dairy
Central to maintaining a Kosher lifestyle is the complete separation of meat and dairy products:
- Meat and milk products may not be mixed in the same product
- Separate utensils must be used for meat and dairy production
- Production lines and equipment used for non-Kosher products may render products non-Kosher
Rabbinic Supervision
Kosher foods must meet complex and strict requirements of Jewish law. To monitor compliance:
- Rabbis audit production and packaging operations
- Facilities are inspected from raw material intake to final storage
- Continuous supervision ensures ongoing compliance
- Certain cooked foods require Jewish supervision during preparation (e.g., turning on ovens)
Equipment and Facility Requirements
- Production lines and equipment must be suitable for Kosher requirements
- Facilities that process non-Kosher products can often be “Kosherised” (cleaned) for batch production
- Dedicated Kosher production lines are ideal but not always necessary
- Proper segregation of Kosher and non-Kosher materials is essential
Beyond Food Products
Kosher certification also applies to:
- Cleaning products
- Water softeners
- Food containers and packaging
- Cosmetics and personal care items
Kosher Food Categories
Meat & Poultry
Kosher Animals:
- Cow, goat, sheep (animals that have split hooves and chew the cud)
Non-Kosher Animals:
- Pig, horse, camel, rabbit
Kosher Poultry:
- Chicken, turkey, goose, duck
Additional Requirements:
- Slaughter must follow Jewish law (shechita)
- Blood must be removed through salting or roasting
- Strict rabbinical supervision is required throughout
- Retail products with animal-derived ingredients are assumed non-Kosher unless certified
Dairy
- Dairy products must come from Kosher animals
- In countries where civil law guarantees milk source (EU, USA), some authorities allow milk without full-time supervision
- Cholov Yisroel (Super Kosher) requires full rabbinical supervision and is required by some communities
- Cheese requires full-time Kosher supervision due to rennet which may be animal-derived
- Supervision ensures complete traceability of all ingredients
Eggs
- Eggs are Kosher only if they come from Kosher birds
- Eggs must not contain any blood spots
Fish
Kosher Fish:
- Must have fins and easily removable scales
- Examples: salmon, tuna, sole, plaice
Non-Kosher Fish:
- All shellfish (shrimp, lobster, crab)
- Eels, shark, monkfish, huss, catfish
Fish Derivatives:
- Roe and fish derivatives (oil, gelatine) must come from Kosher fish
Pareve (Neutral Foods)
Parev (also spelled pareve or parve) means the product is neutral:
- Contains no meat or milk substances
- Not produced on equipment used for meat or dairy products
- Generally presents fewer Kosher complexities
- Can be eaten with either meat or dairy meals
Insects
- All insects are strictly non-Kosher
- Fruits and vegetables must be thoroughly inspected and cleaned
- Pesticides alone are insufficient as they kill but do not remove insects
- Some produce requires extra attention: artichoke hearts, strawberries, leafy greens
- Susceptibility to infestation varies by season and country
Wine and Grape Products
- All grape products require supervision throughout manufacturing
- Handling must be performed exclusively by Jewish personnel
- Affected products include: grape juice, grape sugar, wine, wine vinegar
- Products with grape flavouring or additives require Kosher certification
- These requirements apply to fresh and dried grape products
Passover Certification
Every spring, Jewish people celebrate Passover for 8 days with additional dietary restrictions:
Prohibited During Passover:
- Unleavened products from five grains: wheat, barley, oat, spelt, rye
- Derivatives from these grains (e.g., ethanol from wheat starch)
- For many communities: Kitniyot (legumes/pulses) including corn, soy, rapeseed, peanuts, peas, beans, rice
Requirements:
- Equipment used for prohibited grains must undergo Kosherisation
- Constant supervision of production is usually required
- Kosher for Passover products are marked with a ‘P’ next to the Kosher logo
Kosher Certification Process
Step 1: Application
Submit detailed information including:
- Complete list of all ingredients
- Preservatives and additives
- Processing aids
- Production process details
All information is kept strictly confidential.
Step 2: Ingredient Assessment
Each ingredient is evaluated based on Kosher sensitivity:
- Some ingredients require additional information
- Kosher certificates may be required for specific components
- Supply chain traceability is established
Step 3: On-Site Inspection
A rabbinic auditor visits your facility to inspect:
- Raw material intake
- Storage areas (raw materials and finished products)
- Production processes
- Cleaning procedures
- Segregation practices
Step 4: Certification Approval
If all requirements are met:
- Signed contract is completed
- Certification fee is processed
- Kosher Certificate is issued
- Products may bear the Kosher logo
Step 5: Ongoing Compliance
- Annual renewal required
- Surveillance audits ensure continued compliance
- Any process changes must be reported
Certification Scenarios
All-Kosher Site
Ideal scenario where all ingredients received are Kosher and all final products can be certified. This simplifies the certification process significantly.
Mixed Production Facilities
Many manufacturers produce both Kosher and non-Kosher products. Certification is still possible through:
- Dedicated Kosher Production Line: Ideal but requires adequate capacity
- Batch Production: With thorough cleaning and proper scheduling, Kosher products can be produced at the beginning of production cycles
- Segregation: Kosher and non-Kosher materials must be kept separate at all stages
Companies already managing food allergen segregation often find Kosher requirements manageable.
Third-Party Manufacturing
If you use toll processors or contract manufacturers:
- Permission must be granted for inspections at their premises
- They must cooperate with Kosher supervision requirements
- Their facilities must meet the same standards
Existing Certifications Help
Most companies applying for Kosher already have standard procedures in place such as:
- HACCP
- ISO certifications
- BRC certification
These existing systems support the Kosher certification process and demonstrate your commitment to quality and safety.
Types of Kosher Certificates
Annual Kosher Certificates
- Valid for one year from date issued
- Requires renewal and surveillance
- Most common for ongoing production
Batch Kosher Certificates
- Issued on a per-batch basis
- Only valid for that specific batch
- Used for limited or trial production runs
Certificate Requirements
- May include specific clauses about logo usage
- Batch code requirements may be specified
- All packaging (retail and industrial) should bear the Kosher logo
- Proper logo use ensures acceptance by final customers
