Finding the right Benzotriazole supplier shouldn’t feel like guesswork. But for a lot of procurement teams and formulation buyers, that’s exactly what it is. You’re sorting through vague product listings, chasing distributors who take five days to send a safety data sheet, and trying to figure out whether a $2.50/kg quote is genuinely competitive or a warning sign.
Benzotriazole (CAS 95-14-7) powers entire industries quietly. Corrosion inhibitors, antifreeze formulations, metalworking fluids, UV stabilizers, and even certain ingredients for personal care products depend on it. Demand is consistent and global, but sourcing it well is a different skill than knowing you need it.
This guide covers what Benzotriazole actually costs per kg at bulk volumes, what separates reliable manufacturers from the rest, and how platforms like Elchemy are changing the way global buyers handle chemical procurement. If you’re ready to place a bulk order and want straight answers, read on.
What Is Benzotriazole and Why Do Industries Rely on It?
Let’s get the basics out of the way quickly.
Benzotriazole is a heterocyclic organic compound – molecular formula C6H5N3, molecular weight 119.12 g/mol, white to off-white crystalline solid, melting point around 98-100°C. It’s reasonably water-soluble, which matters a lot for corrosion inhibitor applications where it needs to disperse into aqueous systems.
What does it actually do across industries? Quite a lot:
Corrosion inhibitor: The primary use. Benzotriazole forms a protective layer on copper and copper alloys, which is why it’s in virtually every HVAC water treatment and closed-loop cooling system.
UV stabilizer: In plastics, coatings, and polymers where UV degradation is a concern.
Antifreeze additive: Engine coolants and antifreeze formulations use it for metal protection.
Metalworking fluid component: Protects tool and workpiece surfaces during machining operations.
Specialty UV filter: Some high-performance personal care and cosmetic formulations use it in small concentrations.
The purity standard most industrial buyers should specify is 99%+ (by HPLC). Below that, you start seeing variable performance in downstream formulations – which creates quality control headaches that weren’t in anyone’s budget.
One thing worth flagging: Benzotriazole is classified as a persistent environmental concern under certain EU water framework directives. If you’re operating in Europe or shipping into EU markets, make sure your supplier can provide complete regulatory documentation. That’s not a dealbreaker – it’s just due diligence that will save you a customs clearance nightmare later.
How to Evaluate a Benzotriazole Supplier Before You Commit
This is where most buyers make mistakes.
They find a low price, get a fast response, and interpret that as quality. It isn’t. The chemical distribution market is full of suppliers who are excellent at sending quotations and less excellent at delivering consistent purity, accurate batch documentation, or on-time shipments. The two skills are genuinely separate.
Here’s what actually matters when you’re vetting a Benzotriazole manufacturer or distributor:
Certificate of Analysis (COA) – lot-specific, not generic. Ask for a COA from a recent production batch before you agree to anything. A real COA includes the lot number, test date, purity by HPLC or titration, melting point, moisture content, and appearance. If a supplier sends you a template COA with no batch reference, that’s not a test result – it’s a Word document.
ISO 9001 or GMP certification. Not every supplier needs pharmaceutical GMP, but ISO 9001 at minimum confirms some quality management system exists. For buyers in pharma-adjacent or personal care applications, GMP certification should be non-negotiable.
Minimum order quantity matching your volume. Most Benzotriazole bulk order manufacturers work in 25 kg bags, 50 kg drums, or full pallet quantities. Some won’t touch orders under 500 kg. Know your actual volume before you start the conversation – otherwise you’re wasting both parties’ time.
Lead time transparency. If you’re sourcing from China or India (and realistically, most bulk buyers are), you’re looking at 3-6 weeks for sea freight plus customs clearance. Air freight exists but at $8-15/kg freight cost alone, it only makes sense for genuine emergencies, not routine orders.
Complete documentation support. SDS, customs HS code classification, export certificates, commercial invoices with CAS number – can they provide all of this without you chasing them? If they’re slow on documentation before the sale, picture what happens when you have a customs hold and need something in 24 hours.
Honestly? Finding a supplier who ticks all five without follow-up chasing is rarer than it should be. That’s a real frustration in this space, and it’s part of why more procurement teams are moving toward pre-vetted sourcing platforms.
Benzotriazole Price Per Kg: What You’re Actually Looking At
Let’s talk about money.
Benzotriazole price moves with feedstock costs, Chinese export conditions, energy prices, and seasonal demand from the coolant and antifreeze sector. That said, here’s a realistic range for industrial-grade material at 99% purity based on current market conditions:
- Small quantities (1-25 kg): $8-20/kg
- Mid-volume (100-500 kg): $4-8/kg
- Large bulk (1 MT+): $2.50-5/kg
- Container loads (5-20 MT): $2-3.50/kg
Those container-load prices can look very attractive. But add sea freight ($800-2,500 per MT depending on origin and destination), customs duties, and insurance before comparing them to a domestic distributor quoting $5/kg delivered. The math sometimes shifts significantly.
The frustrating reality with Benzotriazole price per kg is that most suppliers won’t post real-time pricing publicly. You end up spending a week on back-and-forth emails just to get three comparable quotes – and then one of them never confirms their price in writing. That’s time your procurement team doesn’t have.
A few things that genuinely affect what you’ll pay:
Origin: Chinese manufacturers have the lowest base prices by a meaningful margin. Indian manufacturers are competitive and often have stronger English-language communication. European producers cost more but come with easier regulatory documentation for EU compliance.
Purity grade: The difference between 98% and 99%+ can run $0.50-1.50/kg.
Packaging format: 25 kg multi-wall bags versus fiber drums versus IBC containers have different unit costs.
Payment terms: Advance payment versus net 30 affects the effective price.
If you’re seeing quotes under $2/kg for 99% purity from an unknown supplier, treat that with healthy skepticism. It’s not impossible – but it warrants verification before you commit volume.
Comparing Your Benzotriazole Sourcing Options
Different supplier types serve genuinely different buyer needs. Here’s a practical breakdown:
| Supplier Type | Best For | Typical MOQ | Price Range (per kg) | Lead Time |
| Chinese Manufacturer (direct) | High volume, lowest unit cost | 500 kg – 1 MT | $2-3.50 | 4-7 weeks |
| Indian Manufacturer | Mid-volume, strong documentation | 100-500 kg | $3-5 | 3-6 weeks |
| European Manufacturer | High purity, pharma/EU compliance | 25-100 kg | $6-12 | 1-3 weeks |
| Global Sourcing Platform | Flexible volume, pre-vetted suppliers | 25 kg+ | $3.50-7 | Varies |
| US/EU Regional Distributor | Domestic delivery, fast turnaround | 1-25 kg | $8-20 | 1-2 weeks |
The right choice depends on your volume, application, and how much regulatory burden you want to manage yourself. For a 200 kg order of Benzotriazole for a metalworking formulation with no EU regulatory complexity, a direct Asian manufacturer works fine. For 50 kg of high-purity material for a UV stabilizer application where documentation chain matters, you probably want a vetted distributor or sourcing platform.
What the table doesn’t capture: supplier reliability over time. A manufacturer who delivers perfectly on your first order might miss spec on your third. This is why long-term relationships with verified sources matter more than chasing the cheapest quote every procurement cycle. It’s a lesson most buyers learn once, the hard way.
How Elchemy Helps With Benzotriazole Sourcing
If you’ve ever sourced specialty chemicals internationally, you know the cycle. You find a supplier, request a COA, get a PDF that looks like it was scanned in 2009, ask for a cleaner version, wait four business days, receive the same document again, and start the whole process over with a different supplier.
Elchemy cuts that cycle out.
Elchemy is a chemical distribution and custom manufacturing platform serving buyers across 25+ countries. They work with verified manufacturers across Asia, Europe, and beyond – and they handle supplier qualification, documentation, and logistics coordination on your behalf. For a buyer who wants to buy Benzotriazole at bulk quantities without building an entire supplier evaluation process from scratch, that’s genuinely useful.
Here’s what specifically matters for Benzotriazole buyers:
Pre-vetted supplier network: You’re not cold-calling manufacturers from a directory. Elchemy’s suppliers have been assessed for quality documentation, regulatory compliance, and delivery reliability.
Flexible MOQs: Whether you’re ordering 50 kg for a pilot batch or 5 MT for a production run, they can match you to the appropriate supplier tier.
Full documentation support: COA, SDS, customs documentation, HS code classification – handled. This is worth more than most buyers realize until they’ve missed a customs clearance deadline.
Competitive pricing: Aggregating volume across multiple buyers gives Elchemy negotiating leverage that individual buyers typically can’t access independently.
Global shipping coordination: Sea freight, customs brokerage, insurance – managed. Especially valuable for cross-border orders where logistics complexity is real.
Custom manufacturing: Need a specific purity grade, specialized packaging, or a Benzotriazole-based formulation rather than raw material? Custom manufacturing solutions are available.
For procurement teams sourcing multiple chemicals simultaneously – especially when Benzotriazole is one of several components in a broader formulation supply chain – centralizing through Elchemy reduces operational overhead considerably compared to maintaining separate supplier relationships for each ingredient.

Where to Buy Benzotriazole in Bulk: Your Practical Options
A few routes buyers actually use.
Direct from Chinese manufacturers – Jiangsu, Shandong, and Hebei provinces have active Benzotriazole production. Alibaba and Made-in-China list dozens of producers. The catch: due diligence is entirely your responsibility, and quality consistency without ongoing supplier management is genuinely a gamble.
Indian chemical manufacturers – Gujarat and Maharashtra have a growing base of Benzotriazole bulk order manufacturers. Generally stronger English-language communication than Chinese counterparts, good regulatory familiarity with export documentation for Western markets.
Specialty chemical distributors – Brenntag, Univar, and IMCD carry Benzotriazole in some regional markets. Higher per-kg prices, but domestic stock, faster delivery, and easier credit terms make sense for buyers with time constraints.
Global sourcing platforms – This is where Elchemy and similar platforms sit. They operate between you and the manufacturer, managing supplier risk so you don’t have to build that capability in-house.
The “industrial Benzotriazole suppliers near me” search is understandable but often leads nowhere useful. Unless you’re located near a major chemical distribution hub, bulk availability locally is limited. Most serious industrial buyers end up sourcing internationally regardless, which makes a platform with international logistics expertise worth considering from the start.
Red Flags When Working With a Benzotriazole Distributor Worldwide
Some red flags are obvious. Others are subtle. Here are the ones that actually matter:
Vague purity claims. “High purity Benzotriazole” tells you nothing. What’s the actual specification – 98%, 99%, 99.5%? Push for a number, every time.
Generic COA with no lot reference. A COA that doesn’t tie to a specific production lot is a template. It’s not proof that any particular batch was tested. This is a basic one, but suppliers try to get away with it constantly.
Pressure to increase your order volume for pricing you didn’t ask about. Some distributors do this as a tactic to offload inventory. Legitimate suppliers quote your requested quantity without repeatedly pushing for more.
Inconsistent pricing between inquiries. If the same supplier quotes you $3.50/kg in week one and $5/kg three weeks later with no explanation, that’s an administrative disorder that will follow you into every order you place with them.
Slow response on safety documentation. If a supplier takes five days to send you a standard SDS for a regulated chemical, that’s a preview of how they’ll respond when you have an urgent customs hold on an inbound shipment. Not a situation you want to be in.
And one more: suppliers who can’t clearly explain their production capacity or clarify whether they’re a manufacturer or a trader acting as one. The distinction matters for supply chain resilience, and some distributors are deliberately vague about it. Ask directly.
Frequently Asked Questions
What is Benzotriazole used for in industrial applications?
Benzotriazole is primarily used as a corrosion inhibitor for copper and copper alloys in water treatment, HVAC systems, and coolant formulations. It also functions as a UV stabilizer in plastics and coatings, a metalworking fluid additive, and a component in antifreeze products. Some specialty formulations in personal care and photography also use it at specific concentrations.
What’s a realistic Benzotriazole price per kg for bulk orders?
For 99% purity industrial-grade material, expect $2.50-3.50/kg for container-load quantities from Asian manufacturers, $4-8/kg for mid-volume orders (100-500 kg), and $8-20/kg for small quantities from domestic distributors. Treat any quote older than 60 days as potentially outdated – prices move with feedstock and energy costs.
How do I find a reliable Benzotriazole supplier for international orders?
Look for suppliers who can provide lot-specific COAs, clear SDS documentation, and export paperwork for your destination country. Third-party verified platforms like Elchemy reduce the due-diligence burden significantly by working with pre-audited manufacturers. For direct manufacturer sourcing, request a verified sample batch before committing to large volume orders.
What purity grade should I specify when ordering Benzotriazole?
For most industrial applications – corrosion inhibitors, metalworking fluids, antifreeze – 99% purity (by HPLC) is the industry standard. Some UV stabilizer applications in high-performance coatings specify 99.5% minimum. Anything below 98% is generally unsuitable for performance-critical formulations, and the cost savings rarely justify the downstream quality risk.
What’s the typical minimum order quantity for bulk Benzotriazole?
Most manufacturers set MOQs at 500 kg to 1 MT for direct orders. Distributors and sourcing platforms typically accommodate smaller quantities – sometimes as low as 25-50 kg – at a higher per-kg price. If you’re in product development or pilot batch stage, a flexible distributor is worth the price premium over chasing manufacturer pricing that you can’t access at small volumes anyway.
Is Benzotriazole subject to any special import or export regulations?
Benzotriazole itself isn’t a controlled substance, but it’s classified as an environmental concern under certain EU water framework directives – particularly relevant for buyers in European markets. When importing, standard chemical documentation applies: SDS, COA, HS code (typically under 2933 – verify the specific subheading for your country’s tariff schedule), and a commercial invoice with the CAS number listed. Always confirm requirements with your freight forwarder or customs broker before the shipment moves.
