This document provides guidance for staff from UNICEF Supply Division and Programme Division (WASH, Education, and Protection sections) on the selection and procurement of appropriate materials and supplies for menstrual hygiene management, particularly during humanitarian response. The guide is meant to familiarise UNICEF staff members with the key characteristics and requirements for the most common menstrual hygiene materials: menstrual cloths, reusable pads, disposable pads, menstrual cups and tampons. For each menstrual material, the environmental, health, and financial aspects are highlighted in individual tables – along with considerations of availability, user experience, and standards and regulations. Technical specifications are provided for each material. The guide concludes with a summary table of these key attributes.
