BEIJING, April 24 -- Foreign food producers who want to sell their products to China might have to register with China's inspection and quarantine authorities every four years, according to a new draft rule released Thursday to solicit public opinion.

The food safety law, to take effect on June 1, requires all foreign food exporters to register with General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) to ensure their products are safe.

The draft implementation rule of the law, released on the website of the State Council Legislative Affairs Office (http://www.chinalaw.gov.cn/), states such registration is valid for four years.

If products cause any major food safety incidents, or companies are found offering fake materials, their registration will be revoked, the draft rule says.

Currently, only foreign meat products manufacturers need to register, without requiring renewals, with China's quarantine authorities, according to rules and regulations from the AQSIQ.

Under current rules, foreign food exporters must offer at least five categories of documents to get registered, including evaluation reports from their local governments and detailed information on the production process.

In addition, the draft rule also stipulates that importers of foreign food products, on which China has no safety standards, will have to get a safety certificate from China's Ministry of Health (MOH) before entering China.

The State Council Legislative Affairs Office said drafting of the 57-article rule is meant to ensure implementation of the food safety law, and the rule is expected to take effect together with the law.
