The carcass type (textile-ply versus steel-cord), belt width, tensile strength rating, and cover rubber grade (general service, oil-resistant, heat-resistant, fire-resistant) are the primary technical parameters. These same specifications often define the scope of antidumping orders, so a detailed technical data sheet from the manufacturer is essential both for classification and for assessing whether an active trade-remedy order applies to a specific product.

Conveyor belts intended for direct food contact in processing environments must comply with FDA regulations governing food-contact materials, specifically that the rubber compounds and any additives used are approved for food-contact use under 21 CFR. While the belts themselves are not subject to FSIS or APHIS inspection, importers supplying food processors should obtain FDA food-contact compliance documentation from the manufacturer to satisfy their customers' regulatory requirements.
