About Qingdao Oliga International Business Co., Ltd. - Multi‑Category Supplier in China

Qingdao Oliga International Business Co., Ltd. operates from China and currently lists five active products in its catalogue. The product set spans marine oils - fish oil, squid liver oil and squid liver paste - and two feed‑grade soy lecithin liquids, reflecting the company’s focus on Agriculture, Essential Oils, Herbal Extracts, Processed Food, Health Food and Chemicals & Allied Products categories.

The marine oil items are typically used in nutraceutical formulations, aquaculture feed and functional food applications, while the soy lecithin liquids serve as emulsifiers and stabilisers in feed, processed foods and health‑food products. Each entry is recorded under the relevant category without any additional product variants or HS codes in the supplied data.

Product Range and Specialties of Qingdao Oliga International Business Co., Ltd.

The catalogue includes fish oil, squid liver oil and squid liver paste, which are marine‑derived lipids rich in omega‑3 fatty acids. In the broader market, fish oil is often sold with EPA/DHA concentrations of 85 % or higher and peroxide values below 5 meq O₂/kg to meet GOED standards. Squid liver oil generally presents a similar fatty‑acid profile with a higher DHA share, and squid liver paste is marketed as a flavoring paste with typical moisture content of 10‑12 % and protein levels around 15‑20 %.

The two feed‑grade soy lecithin liquids are liquid emulsifiers containing roughly 95 % phosphatidylcholine, viscosity between 500‑800 mPa·s at 25 °C, and are supplied in bulk containers for feed and processed‑food manufacturers. Industry practice for such lecithin includes compliance with ISO 9001 quality systems and, where required, Kosher or Halal certification for specific market segments.

Trade and Export Information - Qingdao Oliga International Business Co., Ltd.

China is a major exporter of marine oils and soy lecithin, with shipments usually destined for the European Union, United States, Southeast Asian feed markets and the Middle East. Buyers commonly require certificates such as GOED compliance for fish and squid oils, ISO 9001 or HACCP for processing facilities, and, where applicable, Kosher or Halal attestations. Standard logistics involve bulk packing in 25 kg drums or 200 L IBC totes, loaded into 20 ft or 40 ft containers, with FOB Qingdao or CIF terms frequently used.

Regulatory oversight for these categories includes limits on heavy metals, peroxide value and microbial counts, which are inspected by customs authorities under the HS chapter 15 (animal or vegetable fats and oils) and chapter 38 (miscellaneous chemical products). Exporters from China typically provide a Certificate of Origin and a detailed Certificate of Analysis to satisfy import‑country requirements.
