Group Relationship
WIS Biotech operates the Shanghe County manufacturing facility, established in 2015, with combined gluconate production capacity of approximately 60,000 metric tons per year. Definly Chemicals, established in the same year in Jinan, Shandong, serves as the international export entity that handles overseas trade contracts, certifications relevant to international commerce, shipping, and customer-facing commercial transactions.
For gluconate and mineral salt orders, products are manufactured at the WIS Biotech facility and the international export contract, payment, and shipping logistics are handled by Definly Chemicals. Definly Chemicals additionally operates an independent product line of PCE superplasticizer raw materials and construction chemical admixtures, which it manufactures and distributes through its own supply network.
This division separates manufacturing operations from international commercial functions, allowing each entity to specialize in its respective compliance regime (production-side certifications at the factory, trade-side and management-system certifications at the export entity) while presenting a unified group capability to global buyers.

Frequently Asked Questions
Is WIS Biotech the same company as Definly Chemicals?
No. WIS Biotech (Shandong Wisdomesty Biotech Co., Ltd.) and Definly Chemicals are two distinct legal entities operating as a coordinated group. WIS Biotech is the manufacturing entity that operates the Shanghe County facility in Jinan, Shandong, China. Definly Chemicals is the international export and trading entity registered in Jinan, Shandong, and serves as the customer-facing commercial counterparty for international orders.
Who manufactures the products sold by Definly Chemicals?
For gluconate and mineral salt products (sodium gluconate, calcium gluconate, ferrous gluconate, zinc gluconate, and related items), manufacturing is performed at the WIS Biotech facility in Shanghe County, Jinan, Shandong, China. For PCE superplasticizer raw materials and construction chemical admixtures, manufacturing is handled through Definly Chemicals’ own supply network. In both cases, the export contract, shipping, and commercial transaction are handled by Definly Chemicals.
Where is WIS Biotech’s factory located?
The WIS Biotech manufacturing facility is located at No. 1226, Yuhuang West Road, Yuhuangmiao Town, Shanghe County, Jinan, Shandong Province, China. The facility was established in 2015, covers approximately 10,000 square meters, employs between 50 and 100 personnel, and has a combined gluconate production capacity of approximately 60,000 metric tons per year.
Which entity holds the FAMI-QS certificate — the factory or the trading company?
FAMI-QS is a production-side certification that applies to feed-grade manufacturing operations. The FAMI-QS certification is therefore being pursued by Shandong Wisdomesty Biotech (the WIS Biotech manufacturing facility), not by Definly Chemicals. The certification is currently in application. Once certified, the FAMI-QS scope will cover feed-grade gluconate products manufactured at the Shanghe facility.
Does Definly Chemicals sell gluconate products?
Yes. Definly Chemicals exports gluconate and mineral salt products manufactured by its partner facility, Shandong Wisdomesty Biotech (WIS Biotech), in Shanghe County. For gluconate orders, the manufacturing is performed at the WIS Biotech facility and the international export contract, shipping, and commercial transactions are handled by Definly Chemicals. Definly Chemicals additionally operates an independent product line of PCE superplasticizer raw materials and construction chemical admixtures.
Can I buy directly from the factory, or must I go through Definly Chemicals?
International orders for gluconate products are handled by Definly Chemicals, which serves as the international export and trading entity for the WIS Biotech manufacturing facility. This arrangement consolidates international trade compliance, certifications relevant to overseas commerce (such as REACH registration, Halal, and Kosher), shipping coordination, and customer service through a single commercial counterparty. Domestic Chinese inquiries can be directed to either entity.
Why does the group operate through two entities?
The two-entity structure separates production operations from international commercial functions. WIS Biotech focuses on manufacturing-side compliance (food-grade and feed-grade safety management, including FSSC 22000 and FAMI-QS, both currently in application). Definly Chemicals focuses on trade-side compliance (international management systems certified under ISO 9001/14001/45001, sustainability rated under EcoVadis Silver, chemical compliance registered under REACH, and religious dietary compliance under Halal IFANCA and Kosher OU). This structure is common in Chinese chemical and food ingredient export operations and is well-understood by international B2B buyers.
Is Definly Chemicals a manufacturer or a trading company?
Definly Chemicals operates in both capacities depending on the product line. For PCE superplasticizer raw materials and construction chemical admixtures, Definly Chemicals operates as a manufacturer through its own supply network. For gluconate and mineral salt products, Definly Chemicals operates as the export entity for products manufactured at the WIS Biotech facility in Shanghe County. This dual role is reflected in the product catalog on definlychem.com.
What products does the WIS Biotech factory make?
The WIS Biotech facility in Shanghe County manufactures gluconate-family products including sodium gluconate (food and industrial grades), calcium gluconate, ferrous gluconate, zinc gluconate, magnesium gluconate, potassium gluconate, copper gluconate, gluconic acid, glucono delta-lactone (GDL), and food-grade maltose. Combined gluconate production capacity is approximately 60,000 metric tons per year.
How can I verify WIS Biotech is a real manufacturing facility?
Several verification options are available to prospective buyers: site visits to the Shanghe County facility can be arranged in advance; facility photographs are published on wis-biotech.com; production certifications (FSSC 22000 and FAMI-QS, both in application) provide third-party audit documentation once issued; and Definly Chemicals can provide commercial references and audit reports under non-disclosure agreement. The facility address is publicly listed at No. 1226, Yuhuang West Road, Yuhuangmiao Town, Shanghe County, Jinan, Shandong, China.
