Custom Chemical Sourcing.
Built for Buyers Who Need More.
Not every chemical is a commodity. When you need something specific
— a rare intermediate, a custom blend, or just a product that isn’t listed on any website
— we find it, verify it, and deliver it.
How We Source for You
01
Share Requirement
Tell us what you need. Product name, CAS number, purity, quantity, target price. Even a rough description works. The more detail you give, the faster we match.
02
We Search Network
We query our network of audited manufacturers across China. If it’s a custom synthesis, we reach out to specialist labs. We typically come back to you with options within 2-3 business days.
03
Review Samples & Documentation
We arrange samples (free or paid, depending on the product) along with available COA and MSDS. Third-party testing via SGS, BV, or Intertek can be arranged before you commit to an order.
04
Order & Production
Once you approve, we place the order with the selected manufacturer. A dedicated project manager tracks production and gives you weekly updates with photos.
05
Final QC & Global Delivery
Pre-shipment inspection, loading supervision, full export documentation, and door-to-door delivery options. You get everything you need to clear customs without hassle.
What We Source
Surfactants & Blends
Custom HLB blends, specialty ethoxylates, APG, amine-based surfactants. If you need a specific cloud point or foaming profile, tell us.
Amines & Derivatives
Ethanolamines, ethyleneamines, polyamines, specialty amine derivatives. Including products with limited public listings.
Oleochemicals
Fatty acids, fatty alcohols, natural oils, specialty esters. We source both standard grades and custom specifications.
Custom Synthesis
R&D-scale quantities, kg-level specialty intermediates, molecules not in standard catalogs. We connect you with specialist labs.
Why Source Through Tianao
More Options
Most suppliers only offer what they make or stock. We search a network. That means multiple options for the same requirement — different manufacturers, different specs, different price points. You choose what fits.
Independent QC
A manufacturer's QC team works for the manufacturer. Ours works for you. We verify quality before you pay for a full shipment. If a sample doesn't meet spec, we find an alternative — not excuses
One Point of Accountability
Sourcing from multiple factories usually means managing multiple relationships. Not with us. One contact handles your entire sourcing project, from initial search to final delivery.
Frequently Asked Questions
Q: What if the chemical I need is not listed on your website?
That’s exactly what this service is for. Share the CAS number, product name, or technical specification. We’ll search our network and get back to you with options.
Q: Do you charge a sourcing fee?
For standard bulk orders, our service cost is included in the product price you pay. For highly specialized custom synthesis or R&D-scale projects, a small development fee may apply — always discussed and agreed upfront.
Q: What's the minimum order quantity for custom sourcing?
It depends on the product. For off-the-shelf chemicals from our network, MOQs are typically flexible. For custom synthesis, small kg-level quantities are usually possible. Tell us your target quantity and we’ll find a match.
Q: How long does custom sourcing take?
Stock items: 3-7 days to arrange samples and documentation. Custom synthesis: typically 2-6 weeks depending on complexity. We give you a realistic timeline upfront.
Q: Can you handle REACH registration or other compliance requirements?
We can coordinate with our partners to support REACH, TSCA, and other destination-country requirements. Let us know your compliance needs when you inquire.
Q: What if the product doesn't meet my specifications?
We verify quality at multiple stages before shipment. If, despite this, the product doesn’t meet agreed specs, we work with you on a solution — replacement, alternative source, or refund based on documented evidence.
