Zentria Flow vs LandedCost.co
Both calculate landed costs — but at different moments and with different depth. Zentria Flow stacks every US tariff layer before you order. LandedCost.co tracks what shipments actually cost after you've placed them.
LandedCost.co
Best for importers who need to track per-SKU margins, shipment lifecycles, and Amazon FBA profitability across an ongoing product catalog. Strong post-order tracking. Does not model Section 301 or forced-labor tariff stacking — critical gap for China-origin imports in 2026.
Zentria Flow
Best for importers making pre-order sourcing decisions. Stacks MFN + Section 301 + forced-labor tariffs, AI HS classification, FTA eligibility scoring, compliance auditing, and streaming AI insights. Free tier, $49/month, no contract.

The Critical Difference
The tariff stack that changes everything
On a $5,000 China-origin shipment in 2026, the true duty exposure is not the MFN rate. It's MFN (12%) + Section 301 (25%) + the forced-labor tariff (12.5%) = 49.5% effective rate. That turns a $5,000 product into $14,852 landed. LandedCost.co does not calculate this stack.
Zentria Flow was built for exactly this environment. Every calculation shows all three layers, quantifies the hidden cost gap, and suggests optimisation paths — FTA eligibility, HS code refinement, Incoterm changes — that can reduce exposure before the order is placed.
Frequently asked questions
What does Zentria Flow do that LandedCost.co doesn't?
Zentria Flow stacks all three US tariff layers in a single calculation — MFN base duty, the Section 301 list rate (for Chinese goods), and the forced-labor Section 301 tariff (10–12.5% for 60 economies since 24 July 2026). LandedCost.co calculates basic duty rates but does not model Section 301 or forced-labor tariff stacking. Zentria Flow also provides AI-powered HS code classification, FTA eligibility scoring across 55+ agreements, anti-dumping order monitoring, compliance document auditing, and streaming AI narrative analysis. None of these exist in LandedCost.co.
What does LandedCost.co do that Zentria Flow doesn't?
LandedCost.co is a post-order shipment management platform. It tracks your shipments from purchase order to delivery, maintains a product catalog, calculates per-SKU margins over time, and models Amazon FBA profitability including referral fees, fulfillment costs, and TACOS. These are operational management features for importers who have already placed orders and need to track profitability across a catalog of products. Zentria Flow focuses on the pre-order decision — what will this shipment truly cost before I commit?
Is LandedCost.co cheaper than Zentria Flow?
LandedCost.co Starter is $39/month vs Zentria Flow Growth at $49/month. However LandedCost.co does not include Section 301 or forced-labor tariff stacking — for importers sourcing from China in 2026, missing those two layers understates duty by 37.5% of the goods value on a typical List 3 product. The $10/month difference is irrelevant if the underlying calculation misses 37.5 points of tariff on a Chinese List 3 product.
Can I use both tools together?
Yes — they're genuinely complementary. Use Zentria Flow to make sourcing decisions (should I source from China or Vietnam given today's tariff environment?). Use LandedCost.co to track the actual cost and margins of shipments you've already placed. Many serious importers benefit from both workflows.
