How the Iran War and Hormuz Blockade Are Reshaping Packaging Costs

Where we stand today

The US–Israel war against Iran began on 28 February 2026, and within days Iran had effectively closed the Strait of Hormuz — the narrow waterway through which roughly a fifth of the world's seaborne oil and LNG normally flows. Brent crude surged past USD 120/barrel after the closure on 4 March, and Gulf production from Kuwait, Iraq, Saudi Arabia, and the UAE collectively fell by more than 10 million barrels per day by mid-March. Brent is currently trading around USD 101, roughly 40% above pre-war levels, with an estimated daily production shortfall of 14.5 million barrels.

A fragile ceasefire was announced in early April, but ship traffic through the Strait remains well below pre-war norms and tensions flare regularly. The International Energy Agency has called this the "largest supply disruption in the history of the global oil market".

These cost increases affect every buyer of polymers and shipping containers, regardless of volume or relationship. Corpack is absorbing where it can, but the increases are structural and unavoidable. This is no longer a situation where waiting for markets to normalise is a viable strategy — the cost shock has arrived, and pricing must reflect that reality.

Why oil moves plastic — the basic mechanism

Roughly 4–6% of every barrel of oil ends up as petrochemical feedstock, but for plastics buyers the more relevant figure is this: feedstock (naphtha, ethane, propylene) typically represents 60–70% of resin production cost. When crude spikes, polymer producers face higher input costs almost immediately; when Middle East exports of finished resin disappear, the supply side tightens in parallel. You get a cost-push and a supply-pull shock at the same time.

The Middle East matters disproportionately here. The region hosts some of the world's largest petrochemical complexes (SABIC, Borouge, QatarChem). Asia imports around 70% of its naphtha — the feedstock for PE, PP, and PET — from the Middle East, and when that flow stops, Asian crackers either cut rates or shut down. By 13 March there were 31 force majeure or sales-allocation announcements for chemicals in Asia and the Middle East.

The transmission is mechanical, not psychological: crude up → feedstock up → resin up → packaging up.

Not all plastics are equal — where the pain hits hardest

The price response varies sharply by polymer. Here's what the data shows since the war started:

Polypropylene (PP) — the worst hit. Spot PP prices rose 33.5¢/lb since the beginning of the year, with another double-digit increase expected and prices unlikely to return to pre-war levels through 2026. PP suppliers issued non-monomer hikes of 4–10¢/lb for April, with some scenarios projecting increases approaching 20¢/lb. PP is the workhorse for caps, closures, fliptops, lipstick mechanisms, and rigid jars — everything that touches our standard portfolio.

Polyethylene (PE/HDPE) — supply scarcity dominates. Iran alone was the world's fourth-largest PE exporter at about 2.2 billion lb/year; that volume has effectively vanished. All HDPE has become super scarce, including injection and high molecular weight grades for film, with blow-mold material under particular pressure. PE contract prices could rise USD 0.15–0.20/lb across the first four months of 2026 if both March and April increases land. This is the resin behind our Twin Pack bottles, lotion bottles, shower gel bottles — most of the "everyday" cosmetic blow-mold formats.

PET — moderate but accelerating. PET prices in Europe rose roughly 15% year-over-year in March 2026. Recycled PET is in a more complex spot — virgin scarcity is finally giving rPET a real cost advantage after years of being uncompetitive.

ABS and Polycarbonate — supply risk, not just price. Imported resin availability, especially ABS and PC from South Korea and Taiwan, is under pressure as multiple producers consider force majeure declarations. These are critical for caps, compacts, lipstick cases, and any high-gloss decorative components. Engineering resins (PA, POM) are also up sharply.

Bio-based and alternative materials (BioD, Sughera, PCR) — these are partially insulated from the oil shock but exposed to the same logistics and energy inflation, and PCR demand is now structurally tighter because everyone is suddenly reconsidering virgin plastic exposure. Recycled plastic prices in Asia have jumped from roughly USD 400/ton pre-crisis to USD 1,600/ton, while virgin moved from USD 950 to over USD 1,800 — the gap has narrowed dramatically.

A rough hierarchy of pain, worst to least: PP > HDPE > ABS/PC > PET > rPET/bio-based.

Transport — oil hits packaging twice

Plastic resin is one cost line; getting it (and the finished packaging) from Asia to Europe is another, and both are exposed to the same crude oil price.

Container shipping. Container rates from Shanghai to Jebel Ali jumped from USD 1,800/FEU on 1 March to over USD 4,000/FEU within two days, reflecting carrier emergency surcharges. CMA CGM introduced a USD 3,000/FEU emergency surcharge for Gulf-bound containers, and other carriers have layered on similar fees. For our Asian production partners, this is a direct landed-cost hit.

Wider lane effects. Asia–Europe rates have moved up too, both from bunker fuel costs and from carriers extending the Cape of Good Hope routing they adopted during the Red Sea/Houthi crisis. Major liner operators have diverted from the Suez route around the tip of Africa since late 2023, and the Iran situation pushes a full Red Sea return further out. Effective capacity has tightened not because there are fewer ships, but because vessels are taking longer routes, spending more time at anchor, or exiting the trade lane entirely.

Air freight and parcel. Jet fuel prices pushed Northeast and Southeast Asia to North America rates up by mid-to-high double digits, and FedEx and UPS have implemented higher fuel surcharges. Relevant for samples, urgent customer shipments, and any air-shipped components.

Insurance. War-risk premiums for vessels transiting near the Gulf have risen sharply and are now a more permanent cost layer in any quote that touches Middle East routing.

Container ships specifically — yes, they are directly affected. Bunker fuel costs are linked to crude, so even ships that never go near Hormuz pay more per voyage. Hapag-Lloyd and MSC suspended bookings out of Persian Gulf ports; CMA-CGM stopped accepting all bookings to and from Persian Gulf ports; Maersk suspended new reefer bookings to the region. The diversions ripple through the network even on lanes that don't touch the Gulf, because capacity is finite and rerouted vessels are pulled from elsewhere.

What price increase range is defensible?

This is the question customers and suppliers will both be asking. Based on the data, here is a reasonable framework for early conversations:

• PP-based items (caps, closures, rigid jars) — +18–25%. Aligns with USD 0.20+/lb resin moves; suppliers will push for more.
• HDPE blow-mold (lotion and shampoo bottles, Twin Pack) — +15–22%. Scarcity-driven; expect availability issues as well as price increases.
• PET bottles — +10–18%. Lower than PP and PE, but accelerating.
• ABS and PC components (compacts, decorative caps) — +12–20% plus force majeure risk. Watch for delivery delays, not just price.
• Bio-based and alternative materials (BioD, Sughera) — +5–12%. Mostly logistics and energy pass-through.
• PCR-based — +10–18%. Demand surge as brands flee virgin exposure.
• Ocean freight (Asia → Europe) — +15–30%. Highly route-dependent; surcharges layer on top.
• Total landed cost for Asia-sourced standard packaging — +15–25%. Blended estimate; varies by mix.

Anything materially below these ranges suggests a supplier is absorbing margin — worth understanding why before celebrating. Anything materially above warrants a line-by-line breakdown; some suppliers will use the headlines to push through more than the underlying cost moves justify. Buyers in this volatile market are well-advised to separate the producer narrative driven by geopolitical headlines from actual data.

What this means for cosmetic brands

For brand owners and packaging buyers, the takeaways are practical:

Polypropylene and HDPE exposure is where you'll feel it most. Standard cosmetic packaging — caps, closures, fliptops, lotion and shampoo bottles, lipstick mechanisms, rigid jars — relies heavily on these two polymers. Any project specced primarily in PP or HDPE should be re-quoted with current figures rather than relying on numbers from late 2025.

Made-in-Europe production has become more competitive on a relative basis. European resin is exposed to the same crude oil dynamics, but European-manufactured packaging avoids the ocean freight surcharges, war-risk insurance premiums, and longer lead times that now sit on top of Asian-sourced components. The traditional cost gap between EU and Asian production has narrowed meaningfully — for some formats it has closed entirely once landed cost and risk-adjusted lead time are accounted for.

Alternative and sustainable materials are more competitive than they were six months ago. Materials like BioD (cellulose-based biodegradable plastic), Sughera (cork-based), and PCR were typically premium-priced against virgin plastic. With virgin polymers up 15–25% and alternative materials up only 5–12%, the "green premium" has shrunk considerably. Brands that had paused sustainable packaging projects on cost grounds may find the math has changed.

Plan around availability, not just price. Force majeure declarations on ABS and polycarbonate are the operational risk over the next quarter. Price you can negotiate; missing a launch window because a decorative cap component didn't arrive is harder to recover from. Confirm allocation and lead times early, and consider designing in flexibility — secondary specifications, alternate decoration methods — for any project launching in Q3 or Q4.

Expect the new normal to persist. Most industry forecasts assume prices stay elevated through the remainder of 2026 even if the conflict eases, simply because inventory pipelines have to refill and shipping schedules have to normalize. The reset to pre-war pricing — if it happens at all — is a 2027 question, not a 2026 one.
