Screen product economics
Start with landed cost and break-even. If the model depends on an aggressive selling price, uncertain freight, or a narrow margin, identify that before samples and deposits consume more cash.

What are LIFA sourcing tools?
LIFA sourcing tools are browser-based planning calculators for buyers importing products from China. They turn commercial assumptions into auditable scenarios, show the calculation result, and identify the evidence still needed before supplier selection, deposit, production, inspection, or shipment.

Recommended Workflow
Use the tools in the order decisions happen
A calculator is most valuable when it changes the next question or prevents an unsupported commitment.
Compare supplier evidence
Normalize quotations, then compare price with sample quality, production timing, verification evidence, MOQ, and payment exposure. The cheapest quote is only one part of the decision.
Plan quality and inspection
Model the cost of poor quality, define defects, and prepare an AQL sample discussion. Product severity and compliance may require controls beyond the calculator result.
Build the delivery schedule
Turn supplier promises into dated milestones for samples, approvals, production, inspection, freight, customs, and buffer. Reforecast when a critical input changes.
Trust by Design
Why these calculators show their boundaries
Useful sourcing analysis distinguishes a confirmed fact from a placeholder, estimate, supplier statement, or professional decision.
The formula is visible
Each tool names its inputs and explains the output. Results can be copied, downloaded as CSV, or printed so assumptions can be reviewed with the buying team and service providers.
The buyer controls assumptions
Dedicated tools avoid presenting changing tariffs, freight rates, or supplier claims as settled facts. Replace defaults with current project evidence and preserve the source date.
Boundaries are part of the answer
Every calculator explains what it does not decide. This matters for customs treatment, supplier verification, inspection acceptance, compliance, demand, and cash flow.
Planning Scenarios
Connect several tools without mixing their jobs
The tools are separate because cost, supplier, quality, inspection, and schedule questions use different evidence and should not collapse into one unexplained score.
New product launch
Use break-even and timeline planning before approving MOQ. Add the quality-cost model after sample findings, then update landed cost with confirmed packaging and freight data.
Supplier replacement
Compare candidates under the same specification and quote basis. Weight verification and quality evidence, then model the cost and schedule effect of a pilot or first inspection.
Import cost change
Use the duty tool to isolate classification, valuation, tariff, and tax assumptions. Carry the updated border charges into landed cost and break-even before renegotiating quantity or selling price.

Frequently Asked Questions
China sourcing calculator questions
What buyers should understand before using a planning output in a purchase decision.
China sourcing tools organize cost, supplier, quality, inspection, and timeline assumptions before a buyer commits to a purchase order. They help compare scenarios and reveal which inputs still need supplier, broker, forwarder, or inspection evidence.
Start with the landed cost calculator when comparing product economics. Use the duty calculator for a transparent import-charge scenario, supplier comparison for candidate selection, break-even for channel economics, quality cost for defect exposure, AQL for sample planning, and timeline for delivery scheduling.
No. The tools use buyer-entered values or clearly labeled planning assumptions. Freight, duty, tax, and trade-measure inputs should be replaced with current quotations and destination-market guidance before a decision.
No. The tools do not replace customs, tax, legal, compliance, financial, laboratory, freight, or inspection advice. Their purpose is to make assumptions visible and prepare better questions.
The dedicated tools calculate in the browser and save form state only in that browser for convenience. Inputs are not sent to LIFA unless the user deliberately submits details through a contact or request form.
LIFA can help organize China-side quotation comparison, supplier communication, verification, samples, order follow-up, inspection coordination, and shipping preparation. Final import and destination-market decisions remain with the buyer and qualified local providers.
From Model to Evidence
Use the result to request better documents and confirmations
When a number remains uncertain, convert it into a named evidence request for the party best placed to answer it.
Supplier and quotation evidence
Ask for a comparable quotation, specification acknowledgement, MOQ, packaging details, gross weight, production trigger, payment beneficiary, and dated validity.
Freight and import evidence
Ask a forwarder or broker for the route, charge basis, validity, customs-value treatment, classification, duty, tax, exclusions, and destination fees.
Quality and schedule evidence
Ask for the approved sample, inspection checklist, defect definitions, booking dates, production milestones, corrective-action path, and shipment release rule.
