Update, September 27, 2026: This post was written in October 2025 for the Q4 2025 peak season, and the capacity cuts, shutdown status and dates below describe that period. The duty picture for Indian stone has since changed: granite, marble and quartz from India now pay the normal duty plus a 10% Section 301 duty (since July 24, 2026), and quartz surface products also face a Section 201 safeguard since August 15, 2026. See our current granite and quartz slabs guide and US tariffs on India.
Q4 reality check: why granite and quartz imports face extra pressure
Every Q4, Asia–U.S. trade lanes tighten. Carriers skip sailings, ports absorb backlogs, and importers expect delays. In 2025, the pressure was sharper, whether you shipped from India, Vietnam, Bangladesh, Sri Lanka, Singapore, or China.
The Journal of Commerce reported that carriers cut 30–35% of Trans-Pacific Eastbound (TPEB) capacity in weeks 41–42, one of the steepest reductions in years. At the same time, Port of LA data showed West Coast terminals running at 75%+ yard utilization, stretching timelines by 7–10 days.
Meanwhile, the U.S. government shutdown was making headlines, but Customs kept running, and granite and quartz cargo doesn't require FDA or USDA checks.
The takeaway: Stone importers faced fewer vessels, tighter container space, and longer door-to-door times. The usual 3–4 week buffer no longer worked.
Why Q4 capacity is tighter than usual
Carriers always make service adjustments after Asia's autumn holidays and China's Golden Week slowdown. But in 2025, the cuts were deeper and more disruptive, especially for heavy stone shipments.
- Blank sailings: Entire Asia–U.S. sailings were canceled, pulling 30–35% of TPEB capacity in October (JOC). Space was much harder to lock in.
- Port congestion: LA/Long Beach terminals were running at 75–90% yard use (Port of LA), adding extra dwell days to already tight timelines.
- Container shortages: 20-foot containers, critical for granite and quartz, were in short supply. Importers from India, South Asia, and China paid premiums or split orders.
Bottom line: This wasn't just seasonal turbulence. Cuts, congestion, and equipment shortages made granite and quartz imports more vulnerable than most cargo types.
Unique challenges for granite and quartz importers
Granite and quartz don't behave like standard cargo. Three factors make stone imports more vulnerable during Q4:
1. Weight limits push up costs
Granite and quartz are so dense that a 20-foot container hits the US road weight limit long before it's full. The container can hold more, but the truck can't legally carry it: on a standard drayage move, that leaves roughly 42,000 to 44,000 lb of cargo. The result is more containers per order and a higher cost per slab shipped. Our container dimensions guide lists the payload figures for each box.
2. Port handling adds time
Stone cargo needs specialized cranes and equipment. During Q4 congestion, that means 1–2 extra days of dwell time at West Coast terminals.
3. Higher risk of breakage
Longer voyages and more handling points mean more exposure to damage. For quartz and granite slabs, proper crating and the right container choice are non-negotiable.
Granite and quartz import timelines: normal vs. Q4 2025
For stone importers, the Q4 2025 capacity crunch added 7–10 days to the supply chain. Here's how shipping from Shanghai to Los Angeles compared:
Normal timeline (pre-Q4):
- Ocean transit: 18 days
- Port clearance: 2–3 days
- Final delivery: 2–3 days
- Total: 22–24 days
Q4 2025 timeline:
- Ocean transit: 21–23 days (+3–5)
- Port clearance: 4–5 days (+2)
- Final delivery: 3–4 days (+1)
- Total: 28–32 days
Net impact: Granite and quartz imports faced 7–10 days of added delay, requiring earlier booking and tighter project planning. From India, ocean transit is longer; see our Mundra to Savannah route guide for a typical stone lane.
Your Q4 action plan (for granite and quartz importers)
- Book early to secure space for stone shipments. If you usually book 2 weeks ahead, shift to 3–4 weeks during peak season.
- Optimize container loads. Work slab counts carefully to stay within road weight limits and avoid overweight penalties.
- Communicate buyer timelines. Let customers know Q4 stone shipments may take 28–32 days vs. 22–24 days on a lane like Shanghai to Los Angeles.
- Upgrade packaging for quartz and granite slabs. Proper crating reduces breakage risk during longer Q4 transits.
- Split shipments if needed. For time-sensitive stone imports, splitting reduces all-or-nothing risk.
Government shutdown impact on granite and quartz imports
As of October 10, 2025, U.S. Customs and Border Protection (CBP) was fully operational through the shutdown (which ended on November 12, 2025). That meant:
- Stone imports kept clearing U.S. ports without disruption.
- Tariff collection and entry paperwork continued as usual.
- Granite and quartz shipments faced no additional customs delays.
Why it mattered: Most granite and quartz imports don't depend on FDA or USDA reviews. With CBP running during the shutdown, customs clearance for stone cargo continued without disruption.
Bottom line: The shutdown made headlines, but for granite and quartz importers in Q4 2025, the real challenges were blank sailings, port congestion, and limited vessel space, not government red tape.
Note (October 2025): Beyond the October 14, 2025 Section 232 tariffs on timber, lumber and certain wood furniture and cabinets, the administration had also opened a Section 232 investigation into processed critical minerals and derivative products. At the time, no new duties had been implemented from it, and amendments to the reciprocal tariff order exempted many critical mineral items, so granite and quartz were unaffected. (Source: Sandler, Travis & Rosenberg, P.A.) For the duties that apply today, see the update at the top of this post.
Key Q4 2025 dates stone importers planned around
- October 20 – Diwali (India): Manufacturing and logistics slowdowns around the festival affected stone exports.
- November 11 – Singles' Day (China): The e-commerce peak competed for export capacity out of China.
- November 27–28 – Thanksgiving (U.S.): Reduced terminal and trucking activity, so shipments risked sitting idle.
- Late December – Year-end slowdowns (Asia and U.S.): Reduced factory output and a logistics wind-down.
Capacity relief was not expected until January 2026, so the advice was to ship early to avoid Q4 bottlenecks. The same pattern repeats most years.
How Airlift supports granite and quartz importers
At Airlift, we understand granite and quartz aren't just cargo. They're heavy, fragile, and compliance-sensitive. That's why we've built our support around the realities of stone logistics:
- Wood packaging and origin handling support. The stone itself needs no fumigation, but the wooden crates, A-frames and pallets it ships on must meet ISPM 15 (heat-treated or fumigated, and stamped) or the shipment can be refused entry. If shippers already have their own CHA, we coordinate directly; if not, Airlift connects them to trusted CHA partners who manage packaging compliance and documentation.
- Proactive space booking and blank sailing monitoring. When carriers cut capacity, we track blank sailings and secure container space early, which is critical for stone shipments that can't afford delays.
- Real-time visibility and customs clearance coordination. Importers get end-to-end visibility on granite and quartz shipments, and US entries are filed through our licensed customs broker partners.
Don't let peak-season delays derail your granite and quartz imports. At Airlift, we specialize in:
- Optimizing 20-foot container loads for heavy stone shipments
- Coordinating wood-packaging compliance and CHA support at origin
- Proactive space booking and blank sailing monitoring
- Real-time shipment visibility and customs clearance coordination
