For diapers, ignore the brand and check 3 things: the fit, how often you change it, and whether a sampling notice has named it

No official body has ranked "which brand is best." Only 2 things can be checked: product-quality sampling notices from the State Administration for Market Regulation (市场监管总局), and regulator investigations of a specific event. Expensive does not mean safe, and imported does not mean up to standard. Buy a small pack and try it for 1 week. Look for a red bottom and marks from tightness, and stock up only if it fits.

Cost

From 200 or 300 yuan a month up to more than 1000 yuan, depending on the grade you use.

Benefit

No official body has published a ranking of "which brand is best," so this book does not recommend a brand. Only 2 kinds of information can be checked. The 1st is product-quality sampling notices from the State Administration for Market Regulation. The 2nd is a regulator's investigation of a specific event. After the "infant diaper formamide problem" drew attention in June (6) 2026, the State Administration for Market Regulation led a joint investigation team to look into it.

Notes

When the joint investigation team was set up, it only said "the relevant findings will be announced in due course." TODO (to be checked: the investigation's conclusion. As of September (9) 30, 2026, no conclusion on diapers was found on the State Administration for Market Regulation website or in the national supervision sampling notices of recent years). How to buy in practice: expensive does not equal safe, and imported does not equal up to standard. Buy a small pack and try it for 1 week. Look for a red bottom and marks from tightness, and stock up only if it fits. Those sentences are the author's experience. The UK NHS says common reasons for a red bottom are urine and stool left on the skin too long, not changing often enough, and the diaper rubbing the skin. Some diapers that do not absorb, or do not breathe, can also cause it. The NHS also says the diaper should fit, and should not be wrapped too tight. How to look up sampling notices is in Section 5.
