The agricultural supply industry is the first link in the food chain and Agricultural Industries Confederation (AIC), NIGTA's affiliated trade organisation, operates a set of assurance schemes, to which all NIGTA members comply. The schemes were developed to help prevent major feed and food safety scares and ensure fertiliser security and also in response to consumer, industry, and government requirements.

The schemes are:

	The Universal Feed Assurance Scheme (UFAS) covers the production, merchanting and haulage of compound feeds and feed materials to farms. It embraces all applicable national and EU legislation and Hazard Analysis of Critical Control Points (HACCP).
	The Trade Assurance Scheme for Combinable Crops (TASCC) addresses the handling of grains, pulses and animal feed materials in the supply chain beyond the farm gate, whether the destination is storage, feed, food, seeds or other uses.
	The Feed Materials Assurance Scheme (FEMAS) covers the supply of feed materials from the vast array of supply sources to their point of use.
	The Fertiliser Industry Assurance Scheme (FIAS) covers the areas of fertiliser assurance, security and traceability in the fertiliser industry supply chain.
