Why SINO STARCO CHEMICAL
An Exporter Built Around Urea
Long-term urea export practice — not a generic trading catalogue.
◆
Urea as a core business
Urea — automotive, agricultural and industrial grades — is our primary export line, backed by years of continuous international trade in fertilizer products.
✓
Quality control per lot
Manufacturer COA with every production lot, specification agreed in writing before contract, and pre-shipment inspection arranged when the contract requires it.
▣
Packaging know-how
25/50 kg bags, jumbo bags and bulk — with moisture-control practice (liners, container preparation, bracing) that protects urea through long ocean transits.
⚓
Container & bulk operations
Regular container exports from Qingdao and coordination of bulk vessel shipments for large-volume contracts — including hold inspection and loading sampling.
📄
Complete export documents
Commercial invoice, packing list, bill of lading, certificate of origin and COA as standard — document sets agreed in advance for LC shipments.

Packaging & Loading
Packed for the Ocean, Not Just for the Warehouse
Urea is hygroscopic — packaging and loading practice decide whether cargo arrives free-flowing or caked. These are the standard formats we ship.
1000 kg Jumbo Bags
FIBC for plantations, blenders and industrial buyers. Palletized or loose in containers.
50 kg / 25 kg Bags
PP woven bags for retail distribution chains. Inner PE liners for humid destinations.
Container Loading
Lined floors, even weight distribution and door-end bracing for ocean transit.
Bulk Vessel
For large-volume contracts — hold inspection, loading sampling and port coordination.
Real Export Cases
Documented Urea Shipments
Photos and details from actual exports — loading, packaging and shipping modes. Client identities remain confidential.
Urea Export by Container
Bagged urea shipped in containers for overseas distributors and blenders. Container shipment is the standard mode for bagged cargo in the 100–1000 MT range, giving buyers flexibility on discharge ports and inland distribution.
View Case → Bulk Urea Export by Vessel
Large-volume urea contracts shipped in bulk vessels. Bulk shipment is the standard mode for tonnages where container logistics become impractical, and requires coordination between the producing plant, port and vessel schedule.
View Case → Industrial Grade Urea Shipment
Industrial grade urea supplied to technical buyers — resin and adhesive producers and industrial denitration users — with specification agreed per process and quality verified before shipment.
View Case → Quality & Documentation
Specification in Writing, Quality on Paper
Every shipment is backed by documents the buyer can verify — before loading, not after arrival.

Automotive Grade Urea vs Fertilizer Grade Urea: What Buyers Need to Know
Both look like white urea, but they are not interchangeable. Where the difference lies — biuret, impurities, particle control — and why it matters for DEF/AdBlue production.

Frequently Asked Questions
What is automotive grade urea?
High-purity solid urea used as the raw material for producing AUS 32 / DEF / AdBlue — the 32.5% urea solution injected into the SCR systems of diesel vehicles. Impurity limits (especially biuret) are stricter than fertilizer grade because impurities can damage the SCR catalyst.
What is the difference between automotive grade and agricultural grade urea?
Nitrogen content is similar (~46%), but automotive grade controls biuret, insoluble matter and trace impurities to catalyst-safe levels. Agricultural grade is optimized for crop nutrition and priced as a fertilizer commodity. They are not interchangeable for DEF production.
What packaging is available?
25 kg and 50 kg PP woven bags, 1000 kg jumbo bags (FIBC), palletized or loose in containers, and bulk vessel shipments for large contracts. Inner liners are recommended for humid destinations.
Can you provide COA?
Yes — manufacturer COA per production lot is standard with every shipment. Third-party inspection (SGS, CIQ or buyer-nominated agency) can be arranged before loading.
What information is required for a quotation?
Grade, specification, packaging, quantity, destination port, trade terms, payment terms and target schedule. Quotations are tied to a validity period because urea prices move with the market.
Which loading ports do you use?
Qingdao is our main loading port; other major Chinese ports can be arranged depending on the production source and shipping schedule.
