Description
HIGH-PURITY SPECIALTY INGREDIENT
Dihydroberberine
Dihydroberberine is supplied as a high-purity B2B raw material at 98.0%. This grade is produced to a declared purity with controlled identity, residual solvents and heavy metals, and is released against a batch-specific COA. It is intended for further processing by the buyer or for use as a reference material in development work; it is not a finished consumer product.

Buyer Decision Guide
Buyers approving Dihydroberberine normally agree four points before the first order: the assay method and acceptance range, the identity and isomeric form, the residual solvent limits applicable to the destination market, and the physical form required by the buyer’s process. Confirm these at enquiry stage so the shipment is released to the right specification.
- Assay: 98.0% by HPLC, released batch by batch against the current COA.
- Identity: confirmed by the analytical methods stated in the specification table above.
- Residual solvents and heavy metals: reported per batch and reviewed against the destination market’s limits.
- Physical form: powder as standard; packaging and particle size agreed against the buyer’s process.
- Documentation: COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling requirements are the buyer’s responsibility for the destination market.
How This Grade Differs
Dihydroberberine is often quoted alongside materials of the same or a closely related name at a different purity or in a different form. The two are not interchangeable: purity, residual solvent profile and physical form all change the buyer’s processing yield. Compare quotations on the released assay and the reported impurity profile, not on the headline percentage alone.

For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.

Frequently Asked Questions
Which safety parameters are tested every lot?
Moisture <=5.0%; result 4.20%, ash <=5.0%; result 3.00%, heavy metals and microbiology against the approved specification.
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
How does the material behave in your process?
It is supplied as Fine yellow crystalline powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
How long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
Can the COA be matched to the lot you ship?
Yes. The certificate is issued for the shipped lot, which is the batch LXGZ260626 referenced on the specification.
Can I review the COA before I pay?
Yes. Request the current or representative COA and check identity, method, limits and results before approving the purchase order.
How is the material shipped?
Air and sea freight are both arranged, with the mode chosen against volume, destination and required date. Documents and the HS code are issued with the shipping instructions.
Which documents come with the shipment?
Batch COA, specification sheet, agreed third-party testing where required, commercial invoice, packing list, certificate of origin and transport documents. The exact set is confirmed against the product and destination market.
