THE Federal DOT LAW - 35% H2O2 is Extremely volatile and can swell and burst during transit, causing harm to people and packaging damage. Solutions over 8% MUST be Insured and pay a $25 to $35 Hazmat Chemical Transport Fee, have a Hazardous Liquid label on the bottle and box, be packed in absorbant material and requires an Adult Signature on delivery. If ALL of these precautions are not followed the product is illegally shipped. Are you currently not paying the fee? You may Not have a legitimate product. If not a chemical safe bottle, toxins can release into the product. H2O2 MUST be diluted from 35%. We provide a Certified MSDS Sheet, an FDA required document, proving that we ONLY use 35% FOOD GRADE H2O2 and a purified Distilled Water diluted to a safe and manageable 8% Solution.
