In the seed processing and production of modern seed industry, a sound and well‑developed quality control system for seed processing and production serves as the core guarantee for seed quality. After years of establishment and improvement, Xinjiang Hongtai Seed Industry has built a complete seed processing and production quality control system and quality management system, and obtained ISO9001:2015 international quality system certification in 2021.

The company’s seed processing and production quality control system mainly consists of two parts: the seed‑cotton procurement and processing control system, and the seed processing quality control system.

Within the seed‑cotton procurement and processing control system, starting from the classified stacking of seed cotton by variety upon procurement, scattered seed cotton in stacking areas is promptly removed to avoid variety mixing. Standardized processing is ensured through procedures including cleaning of seed cotton pickers, rib bars at cotton‑suction pits, and ginning processing equipment.

In the seed processing quality control system, fuzzy seeds of different varieties are stacked separately to prevent cross‑contamination. Incoming fuzzy cotton seeds are inspected in a timely manner to guarantee qualified raw seed quality. Processing technologies including dilute sulfuric acid delinting, dual‑color sorting and dual‑magnetic sorting are adopted. On‑site inspectors conduct regular tests for seed breakage rate and residual acid rate, and feed back test results in real time to secure seed processing quality.

Seed coating is performed with seed coating agents manufactured by Syngenta, a world‑renowned brand, to further enhance seed quality. Before finished seeds are put into warehouse, they must pass laboratory tests for germination rate, moisture content and purity before warehousing and sales, so as to guarantee final quality of seeds released to the market.

By strict control over every procedure, the seed processing and production quality control system safeguards product quality from raw materials to finished goods, and improves the overall seed production performance and market competitiveness of products.
