Container Economics Calculator for Material Imports
Compare 20ft FCL, 40HQ FCL, and LCL for imported construction materials. Pre-loaded with real material density so you don’t guess CBM.
Estimates based on USITC and CBP data. Verify duty classification before commit. Methodology →
Use sqft for tile, slabs for quartz, units for cabinets/vanities/doors, boxes for hardwood.

40HQ is ~44% cheaper per sqft than 20ft. If you have storage and capital, going bigger saves money.
For Atlanta destinations, routing through Savannah typically saves $400–800 vs Miami port + Atlanta drayage.
- Standard ocean freight. AD/CVD and Section 301 not included here (this calc covers transit only).

Methodology and data sources
Container costs use Freightos benchmark indices Q2 2026 for major lanes. 20ft FCL is computed as ~60% of 40HQ FCL (industry standard ratio). LCL is priced per CBM using a blended $90–$180/CBM range for major Asia-US lanes; the calculator uses the midpoint $135/CBM.
Material density values (sqft per 40HQ, slabs per container, etc.) are industry-standard pallet/crate capacities verified with Nexo's supplier network in Q2 2026. Actual yield varies ±10% by supplier crating quality and palletization standards.
This calculator covers FREIGHT ONLY. For total landed cost including customs duties, Section 301, AD/CVD, MPF, HMF, broker fees, ISF, bond, and drayage, use the Landed Cost Calculator — and read the landed cost explainer for how each line item rolls into the per-unit number. Estimates here are not legal or customs advice.

Frequently asked questions
What's cheaper: a 20ft container or a 40ft container?
A 40HQ costs $1,500–$2,500 more than a 20ft but holds 2.4x more volume. Per-unit, 40HQ is typically 20–40% cheaper if you can fill at least 70% of it. For smaller volumes, 20ft FCL or LCL is more cost-effective.
How much porcelain tile fits in a 40ft container?
A 40HQ holds approximately 22,000 sqft of standard porcelain floor tile (8mm thickness, palletized). Large-format tile (10–12mm) reduces capacity to ~18,000 sqft. Pool/decorative tile fits less due to crating overhead.
When should I use LCL instead of FCL?
Use LCL (Less than Container Load) when your shipment is under 15 CBM. Above that, 20ft FCL is usually cheaper because LCL adds consolidation and de-consolidation fees ($150–$400). LCL also has longer transit times.
How long does a 40ft container take from China to Miami?
Standard transit is 28–35 days port-to-port (Shanghai → Miami via Panama). Add 5–7 days for production cutoff and 3–10 days for US customs clearance + drayage. Total order-to-warehouse is typically 6–9 weeks.
What's the difference between 20ft, 40ft, and 40HQ container?
20ft holds ~33 CBM. 40ft standard holds ~67 CBM. 40HQ (High Cube) holds ~76 CBM at the same length but is 1 foot taller. For volume-sensitive cargo like tile and cabinets, 40HQ is the industry standard.
Can I split a container between multiple suppliers?
Yes — this is called consolidation. Your freight forwarder coordinates pickup from multiple factories and combines into one container. Adds $200–$500 in handling but can dramatically reduce per-unit cost for smaller orders.
How do I calculate cost per sqft for imported tile in a 40ft container?
Divide total container freight cost ($3,000–$5,000 China→Miami in 2026) by 22,000 sqft (typical 40HQ porcelain capacity). That gives $0.14–$0.23/sqft freight alone. Add duties, broker fees, and insurance for full landed cost.
Is shipping from Vietnam cheaper than China?
Slightly. Vietnam (HCMC → Miami) is typically $200–$400 cheaper per 40HQ than China (Shanghai → Miami). More importantly, Vietnam avoids the Section 301 25% tariff on most building materials, which is a much bigger saving.
What is CBM and how does it affect my shipping cost?
CBM (cubic meter) is the volume measurement for ocean freight. LCL is priced per CBM (~$90–$180/CBM blended on major lanes). For dense palletized cargo (like tile), the CBM you occupy is much less than the container capacity, which is why LCL can be surprisingly cost-effective for small dense loads.
Are container rates seasonal?
Yes. Q4 (Sep–Nov) sees peak rates due to holiday import surge — rates can be 30–60% higher than Q1. Chinese New Year (late Jan/Feb) creates a pre-CNY rush followed by a 4–6 week production freeze. Plan around it.
