These answers cover common B2B questions about WIS Biotech, gluconate ingredient grades, documentation, samples, orders and international shipping. Product availability, specifications, certificate scope and commercial terms are confirmed in the current quotation and controlled documents for each order.
For efficient qualification, begin with the exact product and grade rather than a general company claim. A certificate shown on a website may cover a particular entity, site or activity without covering every material. Likewise, a typical MOQ or shipping route is planning information, not a contractual promise. Buyers should align the specification, COA requirements, intended application, destination rules and commercial terms before approving a supplier. This page explains what information to exchange and which document should control when website summaries and transaction-specific records differ.

Grades, Specifications and Certificates
Which grades are available?
WIS Biotech focuses on food-grade, feed-grade and selected industrial-grade ingredients. Not every product is available in every grade, and products on this site are not positioned as pharmaceutical-grade materials.
Does every certificate cover every product?
No. Certificate applicability depends on the legal entity, manufacturing site, product, grade, certified scope and validity period. Buyers should request the current controlled certificate for the exact material.
Which technical documents can buyers request?
Depending on the product and qualification stage, the package may include a specification, representative or batch COA, TDS, SDS, origin statement, allergen or GMO statement, applicable certificates, packaging information and shelf-life conditions.
The certification page is an overview; the controlled document supplied for the order governs.
Samples, MOQ and Orders
How can I request a sample?
Provide the product name, grade, target market, application, required specification, sample quantity and delivery country. Sample availability, charges and freight are confirmed before dispatch.
What is the minimum order quantity?
MOQ varies by product, grade, packaging and production schedule. Many dry gluconate products use a commercial starting quantity around 500 kg, while some high-volume or liquid products may start around 1 metric ton. The written quotation confirms the applicable MOQ.
Can several products be combined in one shipment?
Combination may be possible when product availability, packaging, compatibility, freight economics and export documentation allow it. The sales team confirms the feasible loading plan.
Which payment terms are available?
Available payment terms depend on order value, destination, credit review and contract. Only the signed quotation or sales contract should be treated as the agreed payment condition.
Shipping and Supplier Qualification
Which shipping methods and Incoterms are available?
Samples may move by courier or air, while commercial orders commonly move by sea freight. Available Incoterms and ports depend on the route, product, quantity and current quotation; no single delivery term is guaranteed for every destination.
What information helps WIS Biotech prepare an accurate quotation?
Send the product, grade, specification, quantity, packaging, destination, target Incoterm, required delivery window and document list. These details reduce clarification time and help align the offer with the intended use.
How should a buyer approve a new lot?
Compare the batch COA with the agreed specification and purchasing requirements. Where performance is formulation-dependent, complete incoming checks and a qualification trial before full commercial use.
