Global Chemical Co., Ltd, the Thailand-based manufacturer trading as Glochem, has supplied zinc chemicals since 1974. But most of the world’s zinc chloride is actually produced in China, and if you’re comparing options for a bulk order, it’s worth seeing what China’s manufacturer landscape looks like before you commit.
This guide walks through several real, China-based zinc chloride manufacturers, what’s publicly known about each, and what to check before choosing any of them.

China’s Shandong and Hebei provinces are the main production hubs for export-grade zinc chloride.
Quick Comparison: Global Chemical Co., Ltd vs. China-Based Alternatives
| Supplier | Country | Founded | Public Grade Range | Certifications Stated |
|---|---|---|---|---|
| Global Chemical Co., Ltd (Glochem) | Thailand | 1974 | Not published (sold as “Zinc Flux”) | ISO, GMP (company-level) |
| Yanggu Zhongtian Zinc Industry | China (Shandong) | 2001 | 96–98% | ISO 9001 |
| CoastalZinc Group | China | Not published | 96–99% powder, 30–70% liquid | REACH |
| Hebei Jinchangsheng Chemical Technology | China (Hebei) | Not published | 90–99% | ISO 9001 |
| Qingdao Fangjinlong Technology Development | China (Shandong) | 2010 | 95–98% | REACH |
This table reflects what’s publicly stated on each supplier’s own listings or website as of this writing. Gaps in the table are real gaps in public information, not omissions on our part.
Why Look Beyond Global Chemical Co., Ltd?
Glochem is a legitimate, decades-old manufacturer, and its position in the galvanizing flux market is well established. But its zinc chloride product page doesn’t publish a purity percentage, product-specific certifications, or a sample policy, so a buyer sourcing for battery, water treatment, or chemical synthesis use has little to verify against before ordering.
China’s zinc chloride manufacturing cluster, concentrated in Shandong and Hebei provinces, produces the bulk of the world’s supply across both 95% industrial and 98% battery grade. That gives buyers more options to compare on the specific things that matter: documented grade percentages, certifications, and how the product is used across different industries.
China-Based Alternatives to Compare
1. Yanggu Zhongtian Zinc Industry Co., Ltd (Shandong)

Founded in 2001 in Yanggu County, Shandong, this manufacturer’s core products are zinc chloride, zinc ammonium chloride, and basic zinc carbonate. Its listings state ISO 9001 certification and a 96–98% purity range for industrial and battery-grade product, with minimum order quantities commonly listed between 1 and 25 metric tons depending on the listing.
What’s public: ISO 9001, decades of specialization in zinc chemicals, listed MOQs.
What’s not clear from public listings: REACH status, sample policy, and case studies specific to this product.
2. CoastalZinc Group (China)

CoastalZinc manufactures zinc chloride powder (96–99%, pharmacopeia grades including Ph Eur, BP, and USP) and liquid zinc chloride from 30–70% concentration, with a stated annual capacity of 35,000 tons. The company completed EU REACH registration for its zinc chloride line.
What’s public: REACH registration, pharmacopeia-grade options, stated production capacity.
What’s not clear from public listings: ISO certification status and sample policy for industrial buyers specifically.
3. Hebei Jinchangsheng Chemical Technology Co., Ltd (Hebei)

Based in Hebei with a dedicated research center and a separate production base, this manufacturer lists zinc chloride purity ranging from 90% to 99% and holds ISO 9001 certification. It also holds its own import/export permits, which matters for buyers concerned about working with a direct manufacturer rather than a trading intermediary.
What’s public: ISO 9001, direct import/export permits, in-house R&D facility.
What’s not clear from public listings: REACH status and a stated sample policy.
4. Qingdao Fangjinlong Technology Development Co., Ltd (Shandong)

Established in 2010 in Qingdao, this supplier lists REACH certification and a 95–98% purity range for its zinc chloride product, marketed for water treatment, electroplating, and dry-cell battery applications.
What’s public: REACH certification, clearly stated grade range.
What’s not clear from public listings: ISO status and case study material.

Ask every supplier on your shortlist for product-specific certifications, not just company-level badges.
Decision-Maker Insight: A longer supplier list isn’t automatically safer. What actually reduces your risk is a consistent set of documents from whichever supplier you pick: a stated grade percentage, a certificate you can verify, and a sample you can test before the container ships. Compare suppliers on that basis, not just on years in business.

Grade Range: What the Comparison Table Actually Means
The 95% vs. 98% distinction is the first thing to check on any of the suppliers above, because it decides whether a batch fits your application at all.
| Parameter | 95% Industrial Grade | 98% Battery/High Purity |
|---|---|---|
| Zinc Chloride (ZnCl₂) | Min 95.0% | Min 98.0% |
| Iron (Fe) | Max 0.05% | Max 0.001% |
| Sulfate (SO₄²⁻) | Max 0.05% | Max 0.01% |
| Water Insolubles | Max 0.1% | Max 0.05% |
| Heavy Metals (as Pb) | Max 0.05% | Max 0.002% |
Our 95% vs 98% comparison guide covers which applications need which grade in more depth.

98% high-purity zinc chloride is required for battery electrolyte and fine chemical synthesis applications.
Technical Note: Galvanizing flux and general water treatment typically run fine on 95% grade. Battery electrolyte, pharmaceutical intermediates, and fine chemical synthesis need the tighter iron and heavy-metal limits of 98% grade, since trace contamination affects reaction yield and product performance.
What to Check Before Choosing Any Supplier on This List
- Ask for a Certificate of Analysis (COA) matched to the specific batch you’d receive, not a generic product spec sheet
- Confirm certifications for the product, not just the company overall — ISO, SGS, and REACH should apply to the zinc chloride line specifically
- Request a sample sized for real pre-bulk testing (500g–1kg is standard) before committing to container volume
- Ask about factory visits or third-party inspection if the manufacturer’s production line isn’t independently verifiable online
- Clarify MOQ tiers against your actual monthly volume, since listed minimums vary widely between manufacturers and trading companies

From Sample to Bulk Order
Whichever manufacturer you shortlist, a responsible sourcing process runs the same way:
- Consultation — share your industry, required grade, and monthly volume
- Sample — request 500g to 1kg to test against your process
- Trial order — place a smaller first shipment to confirm consistency
- Partnership — scale to full monthly volume once quality is confirmed
A steel galvanizing plant in Poland followed exactly this path as a first-time importer, starting with a documented 95% industrial-grade sample before moving into an ongoing 50-ton shipment partnership.

Frequently Asked Questions
Is Global Chemical Co., Ltd a legitimate zinc chloride supplier?
Yes. It’s a real, established manufacturer operating since 1974 in Thailand. The comparison here is about what each supplier publishes for zinc chloride specifically, not whether any of them exist.
Why does China dominate the zinc chloride manufacturer list?
China’s Shandong and Hebei provinces host dense chemical manufacturing clusters with direct access to raw zinc and hydrochloric acid, which is why most of the manufacturers worth comparing for bulk orders are based there.
What grade of zinc chloride do I need?
Galvanizing and general industrial use typically run on 95% industrial grade. Battery manufacturing and fine chemical synthesis usually require 98% high purity.
Can I get a sample before placing a bulk order?
A responsible supplier should offer this. Ask specifically for a 500g to 1kg sample sized for pre-bulk testing, not just a product brochure.
What certifications should I ask for?
At minimum: ISO 9001, an SGS test report, a Certificate of Analysis (COA), and a Material Safety Data Sheet (MSDS). If you’re importing to the EU, confirm REACH compliance as well. The ECHA REACH regulation page explains what REACH compliance actually requires.
Conclusion
Global Chemical Co., Ltd is one legitimate option among several. China’s manufacturer cluster in Shandong and Hebei gives bulk buyers a wider set of suppliers to compare on grade documentation, certifications, and sample policy. Whichever name you shortlist, from this list or elsewhere, the same checklist applies: a published purity percentage, product-specific certification, and a sample you can test before you commit to a container.
