Four Questions to Put to Any Supplier

Ask thisWhy it matters
Which standard does the report cover?Ask for the report number and the issuing laboratory, and check the report covers this exact design, not only the material.
What is in the fill?For gel pieces, ask in writing that no water beads are used and request the expansion test result under 16 CFR 1250.4.
What is the measured weight?Weight tells you density and density tells you durability. A supplier who cannot give it has not measured it.
How is the carton packed?Pieces per carton, carton dimensions and CBM per 1,000 pieces decide your freight cost per piece.
