PMSIs in Today’s Market: What They Are and Why They Matter for Buyers, Suppliers, and Their Lender

In today’s market, with increasing needs for financing, companies are looking for ways to fund equipment purchases and manage supply‑chain costs without over burdening their balance sheets. At the same time, suppliers are increasingly offering credit terms to help customers acquire the very goods the suppliers are selling—chips, servers, machinery, components, raw materials, you name it.

This is where the purchase money security interest, or PMSI, comes in. A PMSI is a special type of protection (a targeted lien) that sits on the specific goods a supplier (or lender) helps you buy. The Uniform Commercial Code (UCC) defines when a PMSI exists and the conditions that must be met to qualify. A properly structured PMSI can “jump the line” on those specific goods, even if your bank already has a blanket lien on “all assets.” In practical terms, that priority lets suppliers extend credit with more confidence, and it lets customers access better commercial terms without upsetting their senior facility. It’s also why you’ll see PMSIs sitting inside cross‑collateral or vendor‑financing arrangements: the PMSI protects the financed item itself, while the broader collateral package remains with the main lender. The catch is that credit agreements nearly always restrict new liens—they typically include a PMSI exception, but its scope (the “basket”) varies by agreement. The negative covenants in your credit agreement dictate the scope of PMSI (the types and amount of goods) permitted.

This post kicks off a short Freshfields PMSI series designed for those who make financing and procurement decisions. Today, we explain what a PMSI is, inventory vs. equipment PMSIs (and why the inventory version has extra timing and notice hurdles), and the core rules everyone should know. Next up, we’ll dive into how PMSIs interact with lien and debt baskets in real‑world credit agreements, and finally unpack edge cases, like components built into larger assets, proceeds, and coordination with senior lenders, so you can spot opportunities (and pitfalls) before papering the deal.

1. What is a PMSI in simple terms?

A PMSI exists when a supplier or lender enables a customer to buy goods (equipment or inventory) and takes a lien on that same item to secure repayment. Under the UCC, the financing must truly facilitate the purchase of that item, meaning the money or credit extended must be used to buy the goods themselves.¹ To create a purchase money obligation, there needs to be some sort of purchase or supplier agreement. 

This is common in:

• Supplier arrangements for servers, chips, or other components
• Equipment purchases (manufacturing machinery, robotics, IT hardware)
• Vendor financing or cross‑collateral deals tied to a specific product line

If the deal fits the definition and the lien is properly perfected, the supplier or lender gets priority in those financed goods, even ahead of a bank that already has a blanket lien.

The UCC treats PMSIs differently depending on what kind of goods are being financed. The rules are similar, but the steps to get priority are stricter for inventory.

A. Inventory PMSIs (goods held for sale or consumption in production)

Inventory includes raw materials, components awaiting assembly, and finished goods held for resale.

For inventory:

• The PMSI must be perfected before the customer receives the inventory; and
• The PMSI holder must send advance written notice to all lenders with existing filings covering inventory; and
• Those lenders must receive the notice before the inventory is delivered.²

These extra steps exist because inventory turns over quickly, and lenders financing working capital need predictability.

B. Non‑Inventory PMSIs (Equipment, machinery, servers, tools)

When a business buys long‑lived assets used in operations and are not for sale, these are generally equipment.

For equipment:

• The PMSI will have priority if the supplier/lender files its UCC financing statement no later than 20 days after the customer receives the equipment.
• No special notice to the customer’s other lenders is required.
• This simpler process reflects the fact that equipment is not constantly turning over like inventory.³

2. How to tell if your supplier arrangement creates a PMSI

A supplier arrangement likely contains a PMSI if:

A. The supplier financed the purchase.

Extended terms, installment pricing, or supplier‑funded acquisition = potential PMSI.⁴

B. The lien is limited to the specific goods financed.

If the supplier has a lien on “all assets,” that’s not a PMSI.

C. The supplier filed (or intends to file) a UCC‑1 listing those goods.

Perfection is essential, especially within the 20‑day window for equipment PMSIs⁵

D. Inventory PMSI? Then notice must be sent.

If the goods are inventory, check whether notice went to existing lenders before delivery.⁶
