Hydrogen Peroxide Strengths and COA: RFQ Checklist for Textile, Paper and ETP Buyers

35% w/w suits most textile kiers, mid-size HDPE day tanks and plants without dedicated bulk dilution. 50% w/w reduces water shipped per active kg — attractive for high monthly offtake with cool, shaded storage and trained unloading — but it is less forgiving in small carboy handling.

State which strength your dosing pumps and tank labels are calibrated for. Switching from 35% to 50% without retagging is a common near-miss in Gujarat bleach houses.

H₂O₂ assay (% w/w at receipt), stabiliser identity (often tin or phosphorus-based packages — know what your effluent and catalyst steps tolerate), appearance, and lot/date. Peroxide loses assay in heat — inward test or supplier COA date matters for long road legs.

Low-stabiliser or specialty grades for electronics/pharma-adjacent uses are separate SKUs — write “low stabiliser” or attach incumbent spec; do not assume textile grade will pass a clean-room audit.

Store below 30 °C, shaded, ventilated — never in iron or copper contact. HDPE, titanium or approved FRP for tanks; PTFE/PVDF for dose pumps at higher concentrations. Secondary containment is expected under hazmat norms for Gujarat chemical zones.

Keep away from strong reducers and organics that can decompose peroxide. Spill response is dilution and ventilation — MSDS must travel with the lot. Do not reuse food or unrelated chemical drums.

Textile: name fibre (cotton vs blend), kier vs continuous, and whether you pair with caustic and stabiliser — bleach chemistry is temperature-driven. ETP: state if you run UV, ferrous catalyst, or standalone AOP — reactive dyes often need more than peroxide alone.

Packaging RFQ: 30–35 kg carboys for trials, 250 kg drums for regular plants, ISO/tanker for 10 MT+ monthly with compatible unloading at your site. Drashti dispatches with hazmat-aware carriers from Vadodara (GST 24AGLPC6288M1ZX).
