The best CBG suppliers for brands in 2026 sell CBG isolate at 98% or higher, ideally with a CBG distillate option too, backed by lot-specific COAs and clear bulk sizes. Based on what each company publishes, the strongest bulk CBG sources are Bulk CBD Distributors, Red Mesa Science and Refining, GVB Biopharma, KND Labs, Mile High Labs, Open Book Extracts, Zero Point Extraction and Extract Labs. CBG costs more per kilo than CBD because hemp makes less of it, so documentation and lot consistency matter even more here. This guide compares all eight and says which buyer each one suits best.

How We Chose These CBG Suppliers
We looked for US companies that sell CBG to businesses in bulk and checked each one for:
- CBG forms: isolate, distillate and any water soluble or crude options.
- Stated purity: 98% or higher for isolate, and a stated range for distillate.
- Documentation: how you get the COA and whether it matches your lot.
- Sizes and price access: smallest and largest sizes shown, and whether pricing is posted or quoted.
- Evidence it is active: a current site and recent updates.
We left out consumer CBG brands that do not sell bulk ingredients, and we did not repeat claims we could not check. If you are new to the ingredient, start with What Is CBG? The Complete Wholesale Guide.
1. Bulk CBD Distributors
Bulk CBD Distributors is a B2B wholesale supplier of hemp cannabinoid ingredients, in the hemp industry since 2020. We are a distributor rather than a manufacturer: we work directly or indirectly with the major hemp ingredient manufacturers, distributors, and brands, which lets us hand-pick the best batches to resell. That lets us carry CBG in more forms than most single producers and offer the strongest lots we can find in each form. Our CBG isolate is 99%+ cannabigerol from USA-grown, CBG-rich hemp.
- CBG isolate: 99%+ purity, sold online in 100g, 500g, 1kg and 5kg sizes, with larger volumes up to 100kg and beyond by quote
- CBG distillate: Broad spectrum CBG distillate at 80 to 95% CBG, and crystal resistant CBG distillate at 40 to 60% for liquid and vape formulas, both in 500g, 1kg and 5kg
- Other forms: Water soluble CBG at about 20%, and CBG crude oil for processors
- COAs: Representative COAs on each product page, and the batch COA for your lot ships with every order, tested by ISO 17025-accredited third-party labs
- Ordering: Every order is an order request: you pick a size, we confirm the lot and availability, then email payment instructions. Most orders ship the same or next day once payment is received, and some take up to 72 business hours.
Why buyers choose BCD:
- No payment until we confirm. Each order starts as a request, and we confirm stock and your total before you pay. We move fast because good service matters to us, but we are not in a hurry for your money; we would rather earn your business for the long term.
- Make an Offer. On ingredient orders of 1kg or more, propose your own price with our Make an Offer tool, and we reply within 1 to 3 business days.
- Public COA library. 300+ third-party ingredient COAs with batch history in our COA library, open to everyone with no form or login, so you can check batch-to-batch consistency before you buy. It is the largest public bulk ingredient COA library of any supplier we reviewed.
Best for: Brands that want CBG isolate, distillate and water soluble CBG from one supplier, starting from 100g.
Worth knowing: We do not do in-house extraction or custom formulation at a plant. If that is what you need, a manufacturer may fit better.

Should You Buy CBG From a Manufacturer or a Distributor?
A manufacturer makes its own product, which helps when you want to work directly with the plant on custom specs. The trade-off is that one manufacturer rarely makes the best version of everything: a producer with an excellent CBG isolate may not have the strongest CBG distillate or water soluble CBG. A distributor that works with many manufacturers can choose the best lots across the market and change sources when quality shifts, while you keep one account, one set of terms and one contact.
That is how BCD works. We source directly or indirectly from the major hemp ingredient manufacturers, distributors, and brands, hand-select the batches we resell, and ship every order with the batch COA for your lot.
How to Pick the Best CBG Isolate or Distillate Supplier
Start with the form your product needs. CBG isolate suits exact-dose capsules, gummies and tinctures. CBG distillate suits products where you want CBG with other hemp compounds, and crystal resistant grades suit vape and liquid formulas. Our CBG isolate guide and CBG distillate guide cover each form in detail.
| If you need... | Shortlist |
|---|---|
| CBG isolate, distillate and water soluble from one source | BCD, Red Mesa |
| Posted pricing to compare quickly | BCD, Red Mesa, Open Book Extracts |
| Certified organic CBG | KND Labs, Open Book Extracts |
| CBG for UK, EU or Japan products | Mile High Labs |
| Large recurring volume | BCD, GVB, Red Mesa |
Pro Tip: Check the Whole Cannabinoid Panel
CBG is refined from CBG-rich hemp, so a CBG lot can carry small amounts of CBD, CBN or THC. Ask for the full cannabinoid panel, not just the CBG number, and check the THC and THCA lines on every lot.
What Should You Ask a CBG Supplier Before You Order?
- What is the CBG percentage on the COA for my lot, and what else is in the panel?
- Which ISO 17025-accredited lab tested it, and is it independent of you?
- Are Delta-9 THC and THCA reported, and what are the results?
- Is the CBG plant derived, and will you confirm that in writing?
- How consistent is CBG content from lot to lot?
- What are the minimums, volume tiers and lead times?
Section 781 of P.L. 119-37 excludes cannabinoids made outside the plant, so ask every CBG supplier about origin. For the full checklist, see How to Choose a Bulk CBD Supplier, and compare CBG with CBD in CBG vs. CBD: The B2B Formulator's Comparison Guide.
What This Means for Your Business
Many brands are adding CBG to their non-intoxicating product lines, and it costs more than CBD, so the wrong supplier is an expensive mistake. Pick two or three suppliers that sell the CBG form you need, ask each for recent lot COAs and a quote at your real volume, and choose on documentation and consistency before price.

BCD supplies 99%+ CBG isolate, broad spectrum and crystal resistant CBG distillate, and water soluble CBG, tested by ISO 17025-accredited third-party labs with the batch COA on every order. Sizes start at 100g for CBG isolate.
Frequently Asked Questions
What is the best CBG isolate supplier?
The best CBG isolate supplier for most brands sells 98% to 99%+ isolate with lot-specific COAs from an independent ISO 17025-accredited lab, clear sizes and transparent pricing. Match the supplier to the CBG forms, volume and paperwork you need.
What purity should bulk CBG isolate be?
Look for 98% or higher on the COA. BCD lists its CBG isolate at 99%+.
What is the difference between CBG isolate and CBG distillate?
CBG isolate is a crystalline powder of nearly pure CBG. CBG distillate is a refined oil, typically 80 to 95% CBG in broad spectrum grades, that keeps some other hemp compounds.
Why does CBG cost more than CBD?
Most hemp makes much more CBD than CBG, so it takes more plant material and refining to produce a kilo of CBG. That raises the price per kilo.
Is CBG legal under the 2026 hemp law?
CBG is non-intoxicating and generally expected to remain within the hemp definition, but Section 781 of P.L. 119-37 tightens total THC limits and excludes cannabinoids made outside the plant. Confirm plant origin and full THC reporting with your supplier.
What is the minimum order for bulk CBG?
It varies by supplier, from a few grams at some companies to 1kg at others. BCD sells CBG isolate from 100g and CBG distillate from 500g online.
Can I get water soluble CBG in bulk?
Yes. Several suppliers on this list sell it, including BCD, which lists water soluble CBG at about 20%.
Who should use crystal resistant CBG distillate?
Brands making vape cartridges or liquid products where crystals would cause problems. It is typically 40 to 60% CBG and stays flowable.
How do I check a CBG COA?
Match the lot number to the container, check the CBG percentage and the full cannabinoid panel, confirm the THC and THCA lines, and make sure the lab is named, ISO 17025-accredited and independent.
How do I order CBG from BCD?
Choose a size on the CBG product page and submit an order request, or call (303) 339-0343. We confirm the lot, email payment instructions, and most orders ship the same or next day once paid.
How We Made This List
Bulk CBD Distributors (BCD) wrote this guide, and we are one of the suppliers on it. We also work, directly or indirectly, with many of the companies on this list, as a supplier of their inputs, a buyer of their products, or both. We list ourselves first because it is our guide, not because we scored ourselves; the other companies are in no particular order. Everything we say about another company comes from that company's own website or press releases, checked in October 2026, and claims such as certifications are what each company states about itself. Specs, sizes and policies change, so confirm the details with any supplier before you order.
