With the increasing global demand for 1,3-Dimethylurea (DMU, CAS 96-31-1) in textile auxiliaries, pharmaceutical intermediates, organic synthesis, and specialty chemical industries, international buyers are paying more attention to supplier reliability, product compliance, and export documentation.
For chemical products, successful international transactions require more than high-quality materials. Complete and accurate export documents are essential to ensure smooth customs clearance, regulatory compliance, and efficient supply chain management.
From Certificate of Analysis (COA) and Safety Data Sheet (SDS) to commercial invoices and packing lists, each document plays an important role in verifying product quality and supporting international transportation.
As a professional DMU manufacturer in China, Hebei Guangxing Chemical Co., Ltd. provides not only high-quality 1,3-Dimethylurea but also comprehensive documentation support for global customers. With years of export experience, advanced production capabilities, and internationally recognized certifications, we help customers achieve secure and efficient chemical procurement.

The wide application range of DMU makes reliable international supply and professional export management increasingly important.
The Certificate of Analysis (COA) is one of the most important documents for chemical exports.
A professional COA provides detailed information about the quality and specifications of each batch of DMU.
Typical COA information includes:

The Safety Data Sheet (SDS) is another essential document for international chemical transportation.
It provides important safety information, including:
Chemical identification
Hazard classification
Handling instructions
Storage requirements
Emergency measures
Transportation recommendations
Because chemical products may cross multiple countries during transportation, an accurate SDS helps logistics providers and customers properly manage storage and handling procedures.
The commercial invoice is a key document used for customs declaration.
It usually contains:
Seller information
Buyer information
Product description
Quantity
Unit price
Total value
Trade terms
Payment information
Accurate commercial invoices help ensure smooth customs procedures and reduce potential delays.
The packing list provides detailed information about shipment packaging.
For DMU exports, it may include:
Number of packages
Packaging type
Net weight
Gross weight
Package dimensions
