Milton and Cello are India’s two largest mass-market housewares brands. For insulated bottles, both sell double-wall vacuum steel ranges (Milton Thermosteel, Cello vacuum steel) with similar retention on quality SKUs. The tiebreakers are certification (BIS IS 17526:2021 — Milton certifies more SKUs; Cello varies), lid quality, and warranty. Neither is uniformly "better" — pick by SKU, not brand. HYV makes BIS-certified bottles.

Insulation: how they compare

Certification & steel grade
Milton certifies more Thermosteel SKUs to BIS IS 17526:2021. Cello has fewer certified SKUs. Both use food-grade 304 stainless steel on their premium ranges. Read what BIS IS 17526:2021 covers.
Lid quality & hygiene
Lid design is often the weakest link on mass-market bottles. Single-piece silicone-sealed lids resist mould; multi-part lids trap water. See why lids grow mould.
Price & warranty
Cello often undercuts Milton on entry prices; Milton has a stronger premium range and generally longer warranties. Neither dominates on both.

The specifications that actually differ
Almost every brand claims stainless steel, double-wall vacuum insulation and long retention. Comparisons are only useful where they go one layer below that:
- Certification per SKU. BIS IS 17526:2021 is granted per product, so "the brand has BIS" is not an answer.
- Named steel grade on the inner wall — 304 or 18/8, stated.
- Lid engineering. The part that fails, and the part that decides retention between two identical bodies.
- Spares availability. Whether a replacement lid exists at all.
- Warranty exclusions, which are more informative than the headline period.
