Based in China, Xi'an Huilin Bio-Tech Co., Ltd. lists 16 distinct bioactive compounds across its catalogue. The products fall under the HS chapter 29 organic chemicals, primarily within codes 2932, 2934, 2918, 2938, and 2939, reflecting flavonoids, anthraquinones and related polyphenols. Items such as Hesperetin (HS 2932.93), Daidzein (HS 2934.90), and Ferulic acid (HS 2918.99) illustrate the chemical diversity offered. The supplier classifies its offerings under the “Chemicals & Allied Products” and “Agriculture” categories, indicating relevance to nutraceutical, pharmaceutical and crop‑protection applications. Each entry specifies purity levels ranging from 90 % to 98 % and packaging formats from 1 g bottles to 1 kg bags.

The catalogue includes well‑known flavonoids such as Apigenin, Chrysin, Quercetin dihydrate and Baicalein, as well as anthraquinone derivatives like Emodin and Chrysophanol. Several entries provide HS codes, for example Curcumin (HS 2938.90) and Resveratrol (HS 2934.99), enabling precise customs classification. Purity claims of 95 % - 98 % align with industry expectations for research‑grade and nutraceutical‑grade materials. Packaging is described in standard bulk units, typically HDPE bags of 1 kg or glass bottles for smaller quantities.
