精度 — precision

What does the name SEIDO mean?

SEIDO Cookware takes its name from 精度 (seido), the Japanese word for precision. It is a fact about the name — a standard the brand holds itself to: exact sizes, one honest surface, and nothing hidden under a coating.

Steak searing in an uncoated stainless steel skillet

Performance

Built to sear.

Uncoated stainless steel takes the stovetop heat that real searing demands and builds the browned fond that makes pan sauces work. The technique is simple to learn — the Learn library covers it step by step.

Frequently asked questions

Is stainless steel cookware safe?

SEIDO Cookware skillets are tri-ply clad, with a 304 (18/8) stainless steel cooking surface. All SEIDO Cookware products are made without intentionally added PFAS and without synthetic coatings. Because the skillets are uncoated, the cooking surface is the steel itself — there is no synthetic layer to scratch, flake, or wear away over years of use.

Do SEIDO Cookware skillets have a nonstick coating?

No. SEIDO Cookware skillets are uncoated by design. The cooking surface is 304 (18/8) stainless steel with no synthetic coating applied — no coating to flake, wear thin, or fail after hard use. Uncoated stainless steel takes high stovetop heat, sears properly, and scrubs back to clean metal. Food release comes from technique — preheating and fat — which the Learn library explains step by step.

Where can I buy SEIDO Cookware in the US?

SEIDO Cookware is sold in the United States on Amazon. This site is the brand's education and product-information home: read the guides, compare the three skillet sizes, then follow the Amazon link on any product page. Both the skillet lineup and the stainless steel lunch box 3-pack are sold on Amazon.com.

What warranty does SEIDO Cookware offer?

Every SEIDO Cookware product is covered by a 5-Year Limited Warranty. That includes the uncoated stainless steel skillets in all three sizes — 8-inch (20 cm), 9.5-inch (24 cm), and 11-inch (28 cm) — and the stainless steel lunch box 3-pack. Because the skillets carry no synthetic coating, there is no surface layer whose failure cuts the pan's working life short.
