Commercial law may also be referred to as business law. It involves a wide body of substantive law governing business transactions. In the United States each state and commonwealth has adopted a form of the Uniform Commercial Code (sometimes called the “UCC”). The UCC has provisions impacting the sale and lease of goods, negotiable instruments, bank deposits, fund transfers, letters of credit, bulk sales, warehouse receipts, bills of lading, investment securities, and secured transactions. Many commercial transactions take place in interstate commerce. As a result statutes adopted by the United States at the national level may be relevant. In addition, business may be international in which case it may be impacted by treaties adopted by the countries where the various businesses involved in a transaction may be located. More than 60 countries have ratified the United Nations Convention on Contracts for the International Sale of Goods.
