Barium sulfate ep bp usp supplier?

Barium sulfate (BaSO4) in pharmacopeial grades (EP, BP, USP) is a common pharmaceutical excipient. If you’re sourcing it, you want “barium sulfate USP/EP/BP grade” or “pharmaceutical grade” with a COA showing compliance to those monographs.

Good starting options (global suppliers that routinely stock pharmacopeial-grade BaSO4)
- Merck MilliporeSigma — typically lists BaSO4 in USP/EP/BP grade for pharma excipients and reagents; provide COA and GMP data.
- Thermo Fisher Scientific — offers BaSO4 in USP/EP/BP grades for pharmaceutical use; includes Certificates of Analysis and regulatory documentation.
- Avantor (VWR) — stock pharmaceutical-grade BaSO4 (USP/EP/BP) with QA documentation and GMP/compliant packaging.
- Spectrum Chemical Mfg. Co. — sells BaSO4 in USP-grade (and other pharmacopeial grades) with COAs and safety data.
- Alfa Aesar (Thermo) — common source for pharmaceutical-grade BaSO4 (USP/EP/BP) with documentation.

Notes and tips for sourcing
- Specify grade clearly: “pharmaceutical grade BaSO4, USP/EP/BP compliant” and ask for current COA/Certificate of Analysis showing conformance to the USP, EP, and/or BP monographs.
- Request regulatory and quality documentation: GMP certificate, batch COA, SDS, sometimes a GMP-compliance statement.
- Check particle size and form: BaSO4 products come in powders with different particle-size distributions; confirm if you need ultrafine vs. standard excipient grade, and whether the monograph requires a specific grade.
- Inquire about packaging and lot sizes: pharma-grade distributors can provide bulk drums or smaller packs with traceability.
- Regulatory region considerations: ensure the supplier’s COA mentions acceptance for use in your country/region (FDA, EMA, etc., as applicable).

Would you like me to tailor a short vendor RFQ (request for quotation) or provide a region-specific shortlist? If you share:
- Your country/region
- Estimated monthly or yearly quantity
- Required packaging size
- Any specific EP/BP/USP monograph notes or test methods
- Any GMP or regulatory requirements
I can draft a precise list and an RFQ template.
