On February 28, 2026, the United States and Israel launched military strikes on Iran. In response, Iran began attacking cargo ships near a narrow stretch of water called the Strait of Hormuz. That waterway sits between Iran and the Arabian Peninsula, and it is one of the most important shipping lanes in the world.

Why does this matter for plastic pellets? Because a large share of the world’s plastic resin is made in countries that border the Persian Gulf. When their ships can’t move, the plastic can’t move either (Esposito, 2026; Hanna, 2026).

If you buy and resell PE or PP pellets, or if you work with a 3PL warehouse to package, store, and ship them, right now is a critical moment. Here is why building up your inventory makes sense:

1. Every day you wait, the price goes up

Pellets you buy today cost less than pellets you’ll buy next week. In a rising market, having extra stock on hand is like locking in a lower price for your future sales. That is a direct profit advantage.

2. Supply is shrinking while demand stays the same
The factories that normally ship PE and PP through the Strait of Hormuz are stuck. Their pellets can’t get out. At the same time, factories around the world still need those pellets to make their products. When supply drops and demand stays steady, shortages happen and distributors with stock on hand are the ones who get to fill orders (Sparrow(b) 2026).

3. U.S. producers are selling to the highest bidder first
Right now, U.S. plastic makers have a big advantage. Their production costs have not gone up as much as overseas competitors. So global buyers are flooding them with orders. U.S. producers are filling international orders first, where the prices are highest. That means domestic distributors may find less material available through normal channels in the short term (Sparrow(a), 2026). Getting your orders in now is important.

4. Your competitors or customers may already be stocking up
Some manufacturers may already be making defensive purchases to protect their own production lines. If your competitors (or customers, if you are a distributor) have stocked up but you have not, you could find yourself short on supply and unable to service demand.

This is the most important question for anyone deciding how much stock to build. Even if a peace deal were announced tomorrow, things would not go back to normal overnight. Here is why:

Step 1: The Strait Has to Reopen

The Strait of Hormuz is not like a regular sea route where ships can just take a different path. It is the only way out for ships coming from the Persian Gulf. Additionally, Iran may have placed naval mines in the water there. If so, those mines would have to be found and safely removed before large tankers can pass. Military experts say that could take anywhere from a few weeks to several months (Christian Science Monitor, 2026).

Step 2: Shipping Companies Have to Feel Safe Enough to Return

Recent experience has shown that re-opening a shipping passage does not immediately alleviate concerns. When Houthi rebels blocked the Red Sea in 2024 and 2025, shipping companies kept avoiding the area even after the danger level dropped. Sailors have the legal right to refuse to work in war zones, and insurance companies have to agree to cover ships before they sail (Miller, 2026).

Step 3: Plastic Factories Have to Restart

Many plastic factories in Asia have already shut down or cut back because their raw materials aren’t arriving. Even after shipments resume, it takes up to two weeks just to restart a plastic production plant. Then the pellets still have to be loaded and shipped, which takes another week or two by sea (Miller, 2026).

Many PE and PP distributors outsource the physical work of receiving, (re)packaging, and storing pellets to a third-party logistics company, or 3PL. If that is you, this situation could be a direct signal to act.

A good 3PL partner can help you:

• Receive and store larger-than-usual shipments right now, while product is still available and prices are lower than they will be
• Repackage bulk resin into the sizes your customers need, so you can serve orders quickly as supply tightens
• Track your inventory in real time so you always know how many weeks of stock you have on hand
• Stage product in a strategic location, reducing delivery time to your customers
• Help you avoid over-buying by giving you a clear picture of what you already have

One important caution: don’t panic-buy. Industry advisors are warning distributors not to over-order. If you buy far more than your customers need and the conflict ends sooner than expected, you could end up holding expensive stock in a falling market  (Hanna, 2026). The smart move might be to buy enough to cover your likely demand for the next three to five months—not to fill every available space.

A military conflict has created a shortage of PE and PP plastic pellet exports from overseas. Prices are rising and overseas supply is tight. Things are unlikely to return to normal for several months—even if a ceasefire happens soon.

For distributors who buy, store, and resell these materials, the advantage right now goes to those with inventory. Plastic pellets sitting in a U.S. warehouse today are worth more tomorrow than they were yesterday.

Whether you manage your own storage or work with a 3PL partner, the time to review your inventory levels and build safety stock is right now.
