Quick Answer — A bulk Urolithin A (CAS 1143-70-0) powder quote in 2026 typically lands between US$120 and US$900 per kg for 98–99% HPLC purity grades, while pharmaceutical-grade material runs far higher (averaging US$9,200+/kg). The final price is driven by five levers: purity target and test scope, production route (chemical synthesis vs. fermentation), document and certification package, MOQ and packaging, and destination-country logistics. Standard 98% material is the volume tier; 99%+ assay, fermentation-based “clean label” production, and third-party testing each push the quote up 20–40% or more. Buyers who specify these parameters in their first RFQ get tighter, more comparable quotes than buyers who ask for “urolithin A price” alone.
Urolithin A powder price depends on more than the number written in a supplier email. For B2B buyers, the final quote can be influenced by target purity, test method, batch documents, production route, sample requirements, order quantity, packaging, lead time and destination-country shipping support.
This guide explains which details affect a bulk quote — with 2026 price benchmarks, production-method cost comparisons and a ready-to-send RFQ checklist — and how buyers can send a clearer inquiry to a Urolithin A powder supplier before comparing offers.
Urolithin A Price Benchmarks: What Bulk Buyers Are Paying in 2026
Urolithin A is one of the fastest-moving ingredients in the healthy-aging and cellular-health category. The ingredient market was valued at approximately US$0.5 billion in 2025 and is projected to reach US$2.3 billion by 2034 (≈17.8% CAGR); the supplement sub-segment alone grew from about US$115 million in 2025 toward US$378 million by 2032. Dietary supplements account for the largest application share (~48%), and Asia Pacific is the leading producing and consuming region — which is why most bulk quotes originate from Chinese synthesis and fermentation platforms.
Within that demand picture, bulk prices vary widely by grade:
| Grade / Grade Type | Indicative Price Range (USD/kg) | Typical MOQ | Typical Use Case |
|---|---|---|---|
| Standard 98% (HPLC), synthetic | $120 – $850 | 1 kg | Supplement blends, cost-sensitive formulations |
| Premium 99% (HPLC), synthetic | $500 – $900 | 1 kg | High-assay finished products, export to strict markets |
| Fermentation-derived ≥98% | +30 – 40% vs. synthetic | 1 – 5 kg | “Clean label” / natural-positioned brands |
| Pharmaceutical grade (≥99%, controlled impurities) | $9,200+ (average) | small lots | Clinical trial material, reference standards |
The spread between US$120 and US$9,200 per kg is not random. It is the result of four cost drivers explained below. Understanding them lets you target the grade that matches your application instead of over- or under-specifying.
Purity and Test Scope: How HPLC Assay Changes the Quote
Specification is usually the first price driver. A quote for a defined purity, assay method and document scope is different from a general product listing. Buyers should confirm whether the price refers to the requested Urolithin A grade, the current batch, the expected test method and the required packaging.
Most commercial material is standardized to ≥98% purity by HPLC (area normalization), with premium grades at 99% and specialty batches up to 99.8%. Each step up in assay narrows the pool of qualified batches and adds purification and re-testing cost. Equally important is what the COA measures — residual solvents, heavy metals, loss on drying and microbial limits are part of the price, not a bonus:
| Test Parameter | Typical Industry Requirement | Why It Affects Price |
|---|---|---|
| Assay (HPLC) | ≥98% standard; 99–99.8% premium | Higher assay = tighter batch selection + more purification passes |
| Residual solvents | ICH Q3C limits (e.g. DMF, DMSO, ethanol) | GC-MS verification and solvent-removal steps add cost |
| Heavy metals | ICP-MS, per destination market (USP/EU) | Instrument time + third-party lab fees |
| Loss on drying | ≤1.0% | Stability parameter, low cost impact |
| Microbial limits | Food-grade compliance standards | Adds micro testing to every batch |
Buyer alert: residual-solvent control is a real commercial issue, not a theoretical one. In the first half of 2025, at least four food-grade Urolithin A batches (≈280 kg total) shipped from Chinese facilities were rejected and returned by U.S. brands after excessive DMF and DMSO residues were detected — traceable to low-purity precursors. When you compare quotes, ask each supplier for the residual-solvent COA values and the GC-MS method, not just the headline assay. If the purchasing brief requires HPLC assay confirmation, the supplier should quote against that requirement; additional testing can affect both cost and timeline.
Production Route: Chemical Synthesis vs. Fermentation Cost
Two commercial routes dominate bulk supply, and they price differently. Chemical synthesis (multi-step organic reactions from benzoic-acid derivatives) is the volume workhorse: batch-consistent, ≥98–99% purity, scalable, and cheaper at large volume — but it requires strict solvent and impurity control. Microbial fermentation / biotransformation converts ellagic-acid precursors in bioreactors; it supports “natural” and clean-label positioning but typically costs 30–40% more per kg and can have more variable yields.
| Factor | Chemical Synthesis | Fermentation / Biotransformation |
|---|---|---|
| Purity achieved | 98 – 99.8% (controlled) | ≥98% (after purification) |
| Cost at scale | Lower; improves with volume | 30–40% higher than synthetic |
| Batch consistency | High | More variable; yield depends on strain and process |
| Position / labeling | “Synthetic” | “Natural”, clean-label friendly |
| Main risk to watch | Residual solvents & intermediates (e.g. DMF, DMSO, benzoquinones) | Yield variability; allergen traces if pomegranate substrate used |
A scale-up note worth knowing: chemical synthesis can reach ~92% HPLC purification yield at laboratory scale, but kilo-scale production typically drops to 61–67% because structural analogs are hard to remove — a key reason high-purity bulk material carries a premium. For most supplement applications, ≥98% synthetic material is the cost-effective sweet spot; fermentation makes sense when your brand story requires a natural-derived claim or your target market rewards it.
Certification and Document Package: What Adds Cost to a Quote
A supplier quote may include a standard COA, specification sheet and SDS. Some buyers also request allergen statements, manufacturing flow information, residual solvent data, heavy metal test results, packaging information or export documents. Document scope should be discussed before price comparison so the buyer understands what the quote includes.
Regulatory status also varies by destination — and it shapes both documentation and price:
| Region | Regulatory Status (as of 2026) | Sourcing Implication |
|---|---|---|
| United States | FDA GRAS (GRN 791, 2018) for defined foods/supplements | Suppliers should provide GRAS-aligned documentation; USP-style testing common |
| European Union | Novel Food application pending (not yet authorized as food ingredient) | Export to EU food formats is restricted; cosmetic use listed in CosIng |
| China | Cosmetic new-ingredient filing (2023, anti-wrinkle use); not yet approved as food ingredient | Food-grade export mainly targets other markets |
| Japan / South Korea | Cosmetic ingredient listed; not approved as health-functional food | Topical/cosmetic supply only for now |
| Australia / NZ | Permitted as active in listed medicines (TGA NHP) | Adds TGA documentation requirements |
Certification tiers (ISO 9001, cGMP, HACCP, HALAL, KOSHER, FSSC 22000) and third-party lab reports each add handling and audit cost. Ask what is included in the standard COA and which additional tests need separate confirmation before you line up quotes side by side. For detailed COA review points, use HERBSEA’s Urolithin A specification and COA guide alongside this price article.
MOQ, Packaging and Logistics: The Volume Lever
MOQ is another major quote factor. A sample, pilot batch and commercial bulk order may use different packing formats and logistics arrangements. Buyers should state whether they need a small sample for R&D, a kilogram-level pilot order or a recurring supply plan.
| Inquiry Type | What to Confirm | Typical Price Behavior |
|---|---|---|
| Sample request | Sample size, COA, shipping address, test purpose | Fixed sample fee or free with freight collect |
| Pilot order | Quantity, packaging, lead time, document requirements | Higher per-kg; packing set-up costs |
| Bulk supply | Annual demand, batch planning, packing size, export documents | Best per-kg; economies of scale apply |
Packaging can affect both material protection and shipping cost. Buyers should specify whether they prefer small foil bags (light-shielded, moisture-proof, typical 1 kg), larger bags, cartons or standard 25 kg drums. For international shipments, the supplier also needs destination details and any required invoice, packing list, SDS or customs documentation. Temperature-sensitive shipping or cold-chain requirements will add freight cost on top of the material price.
How to Request an Accurate Urolithin A Bulk Quote
A complete RFQ takes about five minutes to write and removes most of the guesswork from supplier pricing:
- State the target product name and purity requirement (e.g. “Urolithin A, CAS 1143-70-0, ≥98% HPLC”).
- Specify production preference if you have one (synthetic vs. fermentation-derived) and application (supplement blend, beverage, cosmetics, clinical).
- Share sample quantity or bulk order volume and expected annual demand.
- List required documents before quotation (COA, residual-solvent GC-MS, heavy metals, allergen statement, export docs).
- Include destination country and target delivery timing.
- Explain finished product format and packaging needs (foil bags, drums, custom labels).
Buyers can send these details through the HERBSEA contact page to request Urolithin A COA, samples and bulk quotation support.
Supplier Evaluation Checklist: 8 Parameters Before You Compare Prices
Before treating two quotes as comparable, check that both suppliers meet these eight sourcing parameters — otherwise you are comparing different products:
| # | Parameter | What to Look For |
|---|---|---|
| 1 | Purity (HPLC ≥98%) | Exact assay value, method reference, batch number on COA |
| 2 | Impurity profile | Total related substances ≤2.0%, unknown impurities controlled |
| 3 | Residual solvents | ICH Q3C compliance; GC-MS report available |
| 4 | Heavy metals | ICP-MS data per destination market |
| 5 | Production method | Synthesis vs. fermentation — verify claim with process docs |
| 6 | Certifications | cGMP, ISO 9001, HACCP, HALAL/KOSHER as required |
| 7 | Batch consistency | Three-batch stability / consistent reproducibility |
| 8 | Documentation depth | HPLC chromatograms, third-party lab reports, traceability |
For compound identity checks, buyers may review PubChem Urolithin A. For U.S. dietary supplement context, the FDA dietary supplements section can support buyer-side regulatory review.
Standard 98% HPLC material is commonly quoted in the US$120 to US$850 per kg range, and 99% grades in the US$500 to US$900 per kg range, depending on production route, quantity and documentation. Pharmaceutical-grade material averages above US$9,000 per kg. Prices move with purity, test scope and volume, so a specified RFQ gets a much tighter quote than an open-ended price question.
The purity gap compounds purification difficulty: kilo-scale synthesis can drop from approximately 92% lab yield to 61–67% production yield because structural analogs are hard to remove. Higher assay means tighter batch selection, extra purification passes and more re-testing, and each step adds cost.
Typically yes, around 30–40% more per kg, because fermentation requires strain development, bioreactor operation and more downstream purification. Buyers pay the premium for natural and clean-label positioning, not for higher purity, since both routes reach 98% or above.
Quotes diverge when the RFQ is vague. Suppliers price against different assumptions about purity, documents, packing and MOQ. A quote for 1 kg with full residual-solvent GC-MS testing is not comparable to one for 500 kg with only a standard COA. Specify every parameter and the spread narrows dramatically.
Very important. In the first half of 2025, at least four batches (approximately 280 kg) of food-grade Urolithin A from Chinese facilities were rejected by U.S. brands for excessive DMF and DMSO residues. A cheap quote without solvent data can cost far more in rejected shipments and rework. Always request the residual-solvent values on the COA.
Purity and assay target, production preference, application, order quantity and annual demand, required documents, destination country, delivery timing and packaging. Buyers who send these six details get comparable quotes that are easier to negotiate.
Summary
Urolithin A bulk pricing is specification-driven: purity and test scope set the grade, production route sets the cost floor, and documents, MOQ, packaging and logistics fine-tune the quote. In 2026, buyers should expect 98% synthetic material in the US$120–850/kg range, 99% grades above US$500/kg, fermentation-derived product at a 30–40% premium, and pharmaceutical grade at a substantial step-change. Send a fully specified RFQ — including residual-solvent requirements — and you will compare comparable offers, avoid rejected batches, and negotiate from facts rather than averages.
