Inquiry about Gastronorm Silicone Lids

I am seeking suppliers for Gastronorm silicone lids in sizes GN 1/1 (530 x 325 mm), GN 1/2 (325 x 265 mm), GN 1/3 (325 x 176 mm), and GN 1/6 (176 x 162 mm). The products must meet specific requirements: 100% food-grade silicone with LFGB or FDA certification, flexible stretch-fit design for an airtight seal, reinforced edges for durability, thickness around 2-3 mm, and temperature resistance from -40°C to +220°C, suitable for heavy commercial kitchen use. At this stage, I need to develop prototypes for each size, understand tooling costs per size, confirm MOQ (minimum order quantity), receive unit pricing for different quantities, and review certifications and quality standards. Additionally, I require estimated lead times for samples and mass production, shipping options to Australia, and details of similar products produced. This is for a long-term product line launch in Australia with ongoing orders after successful testing.
