What Tiger 10 Cup Rice Cooker JNPS18UKY is made of, ingredients and materials
The JNPS18UKY has an inner cooking bowl with a nonstick coating of unspecified chemistry. Tiger does not publicly disclose whether this is Teflon-type coating (Teflon-type), a PFAS-free alternative, or a hybrid formulation. The outer body is aluminum and stainless steel. The undisclosed coating is the primary safety concern because overheating nonstick coatings can release fumes, and degradation from scratching or acidic foods can accelerate leaching.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Non-stick, chemistry undisclosed
Marketed as non-stick without stating the coating chemistry.
Teflon-type coating fume inhalation (nonstick coating)
If the coating is Teflon-type coating and the cooker overheats (e.g., malfunction, no water, metal contact), fumes can be released. Tiger's silence on coating type means this risk cannot be ruled out. Proper use (always add rice and water, no dry running) substantially reduces this risk.
Coating degradation and microparticle release
All nonstick coatings degrade with time and use. Visible flaking or peeling can occur after years of use, particularly if the bowl is scratched or exposed to high heat. Ingested coating particles have limited toxicity data in humans but represent an unnecessary exposure.
Aluminum leaching from bowl interior
The nonstick coating is meant to isolate the aluminum underneath. If the coating is compromised or thin, acidic foods (tomato-based dishes, vinegar) cooked in this cooker could promote aluminum migration into food. This is a general aluminum-cookware concern, mitigated by the coating when intact.
PFAS
Without disclosure, PFAS-based alternatives or processing aids in the coating cannot be ruled out. Tiger's non-disclosure stance and the product's 15/100 PFAS safety score reflect this uncertainty. Request specific coating chemistry from Tiger before purchase if PFAS-free use is a priority.

Steam and lid seal degradation
No specific seal or gasket material data is available for this model. Standard rubber or silicone gaskets used in rice cookers typically do not pose acute safety hazards but can develop mold or odor if not cleaned and dried regularly.
How is this PFAS grade calculated?
The brand's record and disclosure
Tiger has not published transparency statements on nonstick coating chemistry, PFAS use, or safety certifications for this model. The company has no known public commitments to reducing PFAS use in manufacturing. Tiger produces widely used kitchen appliances and has not faced major recalled safety incidents for this specific model, but the silence on coating materials is a red flag in the current regulatory climate.
How it compares in its category
Most rice cookers in this price and capacity range (10-cup) use nonstick-coated aluminum bowls without full material transparency. Some competitors like Zojirushi and Cuckoo have begun disclosing coating details or offering stainless-steel-only options. The JNPS18UKY is typical of mid-range models in obscuring this information, making it neither unusually risky nor unusually transparent.
If you buy it
Never exceed the rice cooker's maximum fill line or use it for prolonged dry heating or high-temperature cooking. Avoid metal utensils that scratch the bowl; use wood or silicone. Replace the inner bowl if the nonstick coating visibly peels, flakes, or degrades. Hand-wash the bowl with mild soap and avoid harsh scouring. Store with the lid off to prevent condensation buildup that can degrade the coating over time.
