Relevant Documents
Washington filers should anchor the contract to Wash. Rev. Code § 62A.2-101 et seq., complete sales-tax registration through Washington State Department of Revenue, and address foreign qualification where the manufacturer is out-of-state. Foreign qualification with the Secretary of State is required if the manufacturer is organized outside the state.
Intellectual Property Assignment Agreement
Ensures that any intellectual property created during the manufacturing process belongs to you rather than the manufacturer. This is particularly important if the manufacturer will be developing custom processes or designs.
Manufacturing Agreement
This is the primary contract that governs the relationship between you and the manufacturer. It outlines the terms of the manufacturing arrangement, including production specifications, quality standards, delivery schedules, pricing, payment terms, and duration of the relationship.
Non-Disclosure Agreement
Protects your confidential information, trade secrets, and intellectual property that you may need to share with the manufacturer during the course of your relationship. This should be signed before detailed discussions begin.
Quality Control Agreement
Specifies the quality standards, testing procedures, and acceptance criteria for the manufactured products. This document helps ensure that the manufacturer meets your quality requirements.
Supply Chain Agreement
Outlines the logistics of the manufacturing relationship, including raw material sourcing, inventory management, shipping arrangements, and delivery schedules.
Termination and Transition Agreement
Outlines the procedures and responsibilities in case the manufacturing relationship ends, including return of materials, transfer of production to another manufacturer, and handling of remaining inventory.
Tooling Agreement
Addresses ownership, maintenance, and usage rights for any specialized tools, molds, or equipment created or purchased specifically for manufacturing your products.
Relevant Laws
Washington Uniform Commercial Code (UCC)
The UCC governs commercial transactions in Washington, including manufacturing agreements. It provides rules for contracts, sales, warranties, and remedies that will apply to your manufacturing relationship. Understanding these provisions is essential when drafting agreements with manufacturers.
Washington Business Corporation Act
If you're establishing a corporate entity to manage your manufacturing relationship, this law governs formation and operation of corporations in Washington. It outlines requirements for corporate structure, liability protection, and compliance obligations.
Washington State Environmental Policy Act (SEPA)
Manufacturing operations often have environmental implications. SEPA requires state and local agencies to consider environmental impacts before approving projects. Your manufacturing facility may need to undergo environmental review depending on its potential impacts.
Washington Industrial Safety and Health Act (WISHA)
This state-level workplace safety law works alongside federal OSHA regulations. It establishes safety standards for manufacturing facilities and imposes obligations on employers to maintain safe working environments. Compliance is mandatory for manufacturing operations.
Washington State Tax Laws
Manufacturing businesses in Washington are subject to specific tax considerations, including Business & Occupation (B&O) tax, which is calculated on gross receipts rather than net income. There may be tax incentives available for certain types of manufacturing activities.
Washington Limited Liability Company Act
If structuring your manufacturing business as an LLC, this law governs formation and operation requirements. It provides flexibility in management structure while offering liability protection that can be valuable in manufacturing relationships.
Washington State Clean Air Act
Manufacturing processes that emit air pollutants are regulated under this law. You may need permits for certain operations, and there are ongoing compliance requirements to monitor and control emissions from your manufacturing facility.
Regional Variances
Western Washington
Seattle has additional business licensing requirements for manufacturers, including potential environmental impact assessments specific to the city code. Manufacturers must comply with Seattle's Fair Employment Practices Ordinance, which has broader protections than state law. The city also imposes a higher minimum wage than the rest of the state, which affects manufacturing labor costs.
Tacoma's industrial zones have specific requirements for manufacturing operations, particularly around the Port of Tacoma. The city offers certain tax incentives for manufacturers in designated revitalization areas. Manufacturers must also comply with Tacoma's specific environmental regulations regarding stormwater management and air quality that may be more stringent than state requirements.
Eastern Washington
Spokane offers specific tax incentives for manufacturers in certain industries, particularly aerospace and advanced manufacturing. The city has different zoning requirements for manufacturing facilities and may offer expedited permitting processes. Spokane County also has unique water usage regulations that affect manufacturing operations due to different water availability concerns than western Washington.
The Tri-Cities area has specialized regulations related to manufacturing that interfaces with the Hanford Site and other federal facilities. Local economic development councils offer specific incentives for manufacturers in targeted industries. These jurisdictions may have different labor availability and cost structures compared to the western part of the state.
Border Regions
Vancouver's proximity to Portland, Oregon creates unique cross-state manufacturing considerations. Manufacturers may need to navigate both Washington and Oregon regulations if their supply chain crosses state lines. The city offers specific incentives for manufacturers who establish operations in designated enterprise zones, with different requirements than other Washington cities.
As a border city with Canada, Bellingham has unique considerations for manufacturers engaged in international trade. The city has specific regulations regarding manufacturing near sensitive waterfront areas and wetlands.
