What small portable storage companies gain October 16, 2026 · 4 min read · National Portable Storage Association A trade association gives small companies shared knowledge, contacts, training and a voice on rules. Whether it pays off depends on how much you use it. Compare the dues with the benefits you will actually use, such as events, training videos, the directory and member-only resources. ![New members at the welcome reception of the NPSA Conference & Trade Show](https://npsa.preview.multisites.ai/_astro/new-members-welcome.t0o0rfSb_1UtMGH.webp) ## What does a trade association do for a small company? A trade association pools the knowledge and voice of many companies in one industry. A small firm can rarely do that alone. Typical benefits include networking, education, advocacy and member discounts. The National Business Association lists networking, educational resources, advocacy, funding help and discounts as the main benefits of joining a small business association. Women In Manufacturing describes shared learning, peer networks and discounted programming as a cost-effective way to build skills without building every program in-house. Those are general benefits. What matters is whether your association serves your industry. For portable storage, that means containers, trailers and mobile offices. ## What is NPSA? The National Portable Storage Association (NPSA) is the trade association for companies that rent, sell or lease portable storage containers, trailers, mobile offices and mobile self-storage units, and for the suppliers who serve them. NPSA does not rent or sell storage itself. Its members do. NPSA states its mission as “To advance the portable storage industry through networking, education, marketing, and advocacy.” It also says it is “dedicated to helping smaller companies grow.” NPSA has “over 700 member companies and counting.” ## What do NPSA members get? NPSA publishes a list of member benefits.

The glossary explains the [mentorship program](https://npsa.preview.multisites.ai/glossary/mentorship-program). ## What are the NPSA membership categories and dues? NPSA has two kinds of members: Regular and Associate. Dues depend on the category. The numbers below are current NPSA dues. **Regular members** are companies “primarily engaged in the renting, leasing or selling of Storage Products” to end users. Storage products are defined as storage containers, semi-trailers, mobile self-storage containers, containerized structures or mobile offices. Regular categories follow the number of staffed locations. Regular category Dues 1: National Company (10 or more staffed locations) $5,000 2: Regular $600 **Associate members** provide product, financial, legal or other services or support to the portable storage industry, and are not eligible to be Regular members. Associate categories follow gross annual revenue. Associate category Dues 1A: Companies with annual revenues of $30M or more $5,000 2A: Companies with annual revenues of $1M to 29M $1,100 3A: Companies with annual revenues less than $1M $700 Wholesale marine container suppliers use a separate scale: Wholesale marine container category Dues 4A: Companies with annual revenues more than $3M $5,000 5A: Companies with annual revenues less than $3M $1,100 Confirm billing terms and how the membership year is counted with NPSA before you apply.

The glossary explains [Regular member](https://npsa.preview.multisites.ai/glossary/regular-member) and [Associate member](https://npsa.preview.multisites.ai/glossary/associate-member). ## How do I decide if it is worth it? Work out what you would use, then compare it to the dues. A short test helps. 1. Pick your category from the tables above. 2. List the benefits you would use in the next 12 months. 3. Estimate what each one is worth to you: a training hour saved, a lead, a supplier introduction, a discount. 4. Compare the total to the dues. This is your own estimate, so be honest about it. 5. Plan how you will take part. Value comes from use. An unread newsletter helps no one. The return is yours to earn. A benefit you never use costs the same as one you use every week. ## What else can a small company do before joining? You can look before you commit. Visit the [events page](https://npsa.preview.multisites.ai/events) and see what the next meeting offers. The 2027 Conference & Trade Show runs April 4-6, 2027 at Paris Las Vegas. Browse the [supplier directory](https://npsa.preview.multisites.ai/sponsors/directory) to see who exhibits. Look at how members get involved on committees. Talk to your insurance agent and a tax professional about how dues and member insurance products fit your business. ## Next step Ready to compare tiers?

[Join NPSA](https://npsa.preview.multisites.ai/join-us) Questions ## Common questions Is a trade association worth the cost? It is worth it if you use what it offers. Add up the benefits you would use, such as events, training, the directory and peer contacts, and compare that to the dues. Attend one event or watch the training videos before you judge. Value grows with participation. What do NPSA members get? NPSA lists these member benefits: networking, discounted event registration, a quarterly newsletter, a printed directory, a website listing with the chance to receive leads, a community forum, member-only resources, a mentorship program, a training video library, member-only insurance products and advocacy. Can suppliers join NPSA? Yes. NPSA has Associate members. Associate membership is for companies that provide product, financial, legal or other services or support to the portable storage industry and are not eligible to be Regular members. Associate dues depend on annual revenue. How do I compare NPSA's membership tiers? Start with the type. Regular members rent, lease or sell storage products to end users. Associate members support the industry. Then find your tier: Regular tiers follow staffed locations, and Associate tiers follow gross annual revenue. Confirm the current dues and billing terms with NPSA before you apply. ## Sources 1. [NPSA: Join Us](https://www.npsa.org/join-us.html) 2.
