Control Requirements for National Standards and Export Inspections

  Gunpowder tea complies with the national standard GB/T 14456.4-2016, while Chunmee tea adheres to the national standard for pan-fired green tea. Export operations involve a dual-standard control system: factory production references local processing standard samples, whereas customs declarations and overseas inspections rely on nationally unified physical trade standard samples. Furthermore, mandatory testing for pesticide residues, heavy metals, and moisture content is required; failure to meet these specifications prevents customs clearance and export, serving as a strict threshold for the tea export trade.
