The competent state agency controls products in Group 2 on the basis of relevant technical regulations as well as by producers on the basis of applicable standards. Different ministries are responsible for the control of quality of products and goods under their responsibility, and for issuing lists of products and goods that can cause "unsafety" and are subject to mandatory inspection. These were removed for tea and coffee in 1995. However, coffee beans remained subject to line management by MARD requiring their approval before export. Export quotas on rice were introduced in 1992 to ensure food security and price stability.
