How to Register a Manufacturing Company in California (Step-by-Step)

A California manufacturing registration is the process of establishing legal authority to produce, process, or assemble goods within the state. It combines a base business entity filing with sector-specific licensing from state agencies.

Step 1: File with the California Secretary of State

Choose your business structure and file the appropriate formation document with the California Secretary of State via the online portal at bizfileonline.sos.ca.gov:

• LLC: File Articles of Organization. Fee: $70. Processing: 3 to 5 business days online.
• Corporation: File Articles of Incorporation. Fee: $100. Processing: 3 to 5 business days online.
• Sole Proprietor: No state filing required, but a local fictitious business name (DBA) registration may be needed.

Both LLCs and corporations must designate a registered agent for service of process and file a Statement of Information annually.

Step 2: Obtain a Federal EIN

Apply for an Employer Identification Number (EIN) from the IRS at irs.gov/ein. The application is free and issues your EIN the same day online. You need an EIN before opening a business bank account, hiring employees, or applying for most state licenses.

Step 3: Register for a California Seller's Permit

Any manufacturer that sells tangible goods in California must register for a seller's permit with the California Department of Tax and Fee Administration (CDTFA) at cdtfa.ca.gov. Registration is free and can be completed online. This permit authorizes you to collect California sales tax from buyers and is a prerequisite for claiming the manufacturing equipment use tax exemption covered below.

Step 4: Obtain Industry-Specific State Licenses

Base registration covers your legal existence. Industry licenses authorize your specific manufacturing activities:

• Food and drug manufacturers: Apply to the California Department of Public Health.
• Cannabis manufacturers: Apply for a California cannabis manufacturing license (DCC).
• Hazardous materials handlers (electronics, chemicals): Register with DTSC.
• Medical device manufacturers: Obtain FDA 510(k) clearance or PMA approval plus CDPH Medical Device Registration.
• Apparel and garment manufacturers: Register with the California Labor Commissioner's Garment Program under AB 633.

Step 5: Secure Local Business Licenses via CalGold

Use the CalGold permit lookup tool operated by the California Governor's Office of Business and Economic Development (GO-Biz). Enter your business type and ZIP code to receive a customized list of required city and county permits. Local license fees range from $50 to $500 or more depending on jurisdiction.

Step 6: Register with Cal/OSHA and Establish an IIPP

All California employers must have a written Injury and Illness Prevention Program (IIPP). Register and access compliance requirements at dir.ca.gov. Cal/OSHA inspections can occur at any time; having your IIPP documented before you begin operations protects you from penalties.

California Manufacturing License Types by Industry

A California manufacturing license is a state-issued authorization, issued by the California Secretary of State, CDPH, DCC, or another relevant agency, that permits a business to legally produce, process, or assemble goods within the state.

Food and Beverage Manufacturing

Companies in the food and beverage sector must maintain licensing for California manufacturers to operate and adhere to guidelines for safe food production, packaging, and labeling.

These businesses must comply with the California Health and Safety Code regarding food safety standards. The California Department of Public Health issues licenses for food-related manufacturers, including frozen food lockers, pet food processors, and shellfish handlers. Additionally, businesses must meet the standards set by the Industrial Welfare Commission, which addresses meal breaks and the Garment Rules and Regulations.

Drug and Medical Device Manufacturing

Drug manufacturers must comply with rigorous federal and state regulations to ensure products are both safe and effective.

This includes obtaining a CDPH Drug and Device Manufacturing License and adhering to FDA standards for controlled substances and non-controlled prescription drugs under Health and Safety Code Section 111635 and federal Good Manufacturing Practice (GMP) standards. For detailed compliance standards, review the How to Navigate Cal/OSHA Regulations guide from CMTC.

Medical device manufacturers must also obtain FDA 510(k) clearance or PMA approval before California sales.

Cannabis Product Manufacturing

Cannabis product manufacturers must obtain a California cannabis manufacturing license (DCC) corresponding to their specific activities, extraction methods, and chemical use.

Cannabis license types:

• Type 6: For manufacturers using non-volatile solvents.
• Type 7: Allows the use of volatile solvents.
• Shared-use Facilities: Manufacturers using shared spaces require a distinct license type.

California does not require cannabis manufacturers to hold a cultivation license, but a manufacturer may hold licenses in multiple categories simultaneously.

Aerospace, Defense, and Electronics

California is the largest defense manufacturing state by output. Manufacturers of defense articles must register with the Directorate of Defense Trade Controls (DDTC) under ITAR (22 CFR Parts 120 to 130).

Electronics manufacturers handling hazardous electronic waste streams must register with the California Department of Toxic Substances Control (DTSC). This registration is separate from your base Secretary of State filing and applies to any manufacturer generating, storing, or transporting hazardous materials.

Apparel and Garment

Garment manufacturers must register with the California Labor Commissioner's Garment Program under AB 633. California garment manufacturer registration is mandatory before beginning production. Failure to register can result in joint liability for wage violations across the supply chain.

California Manufacturing Registration Costs and Timelines

Verify current fee schedules against official agency websites before filing. Fees are subject to change.

Financing Options for Manufacturers

Manufacturing companies in California can explore various financing avenues including traditional bank loans, venture capital, and government grants. Small business loans are often facilitated through SBA programs, which provide lenders with a government-backed guarantee. Review the manufacturing industry financing guide for a full breakdown of options available to California manufacturers.

Understanding Business Taxes

Manufacturers in California are subject to corporate income tax (corporations) and franchise taxes (LLCs). Tax compliance is critical, and companies should consult with a tax professional to confirm adherence to all current regulations.

Best Practices for Manufacturers In California

Maintaining Consistent Quality

Maintaining ISO certifications and documented quality control systems supports compliance with Cal/OSHA and CDPH inspection requirements. Credit risk management practices also support financial compliance and reduce exposure to buyer default.

Manufacturers must keep meticulous records of quality checks and address any discrepancies immediately.

Compliance with Local Regulations In California

Manufacturers must secure appropriate local business licenses alongside their state manufacturer license. Requirements vary by city and county based on the type of manufacturing, products involved, and location of operations.

Local environmental regulations are particularly strict in California, and many counties require additional permits for waste disposal and emissions. Manufacturers should contact their local city or county business licensing department directly.

Review the Compliance: Regulation, Permits, and Licenses resources from CalOSBA and use CalGold (calgold.ca.gov) to identify requirements by ZIP code. Non-compliance with local ordinances can result in fines or a halt in operations.

Financing Your California Manufacturing Operations

Clearing California's licensing requirements is the first hurdle. Cash flow is often the next.

California manufacturers regularly extend Net 30, Net 60, or Net 90 terms to distributors and wholesale buyers. Waiting 30 to 90 days on invoices while managing licensing costs, equipment purchases, and payroll creates a real cash flow gap, especially in the first years of operation.

Resolve advances up to 90% of approved invoices within 24 hours, on a non-recourse basis. That means no credit risk to you if an approved buyer doesn't pay. Collections are handled automatically, so your team stays focused on production, not AR follow-up. Review the full financing for manufacturers guide to see how manufacturers use net terms to grow revenue without straining cash flow. You can also explore accounts receivable automation and B2B payment processing to build a complete AR stack. To reduce DSO without adding headcount, Resolve handles the follow-up automatically.
