Ask who manufactured the device and who is responsible for supplying it locally. Check that the product description, model, and labeling match the item you are being offered.
Request applicable registration documentation and verify that it covers the particular product and its intended use. A supplier statement alone should not replace a documentation check.
Ask about sizing, materials, instructions for use, storage, shelf life where applicable, and the support available for complaints or product issues.
For institutional purchases, consider training, maintenance, consumables, and lifecycle costs. Request clarification before placing an order when the evidence is incomplete.
