Illustrative rates. Actual rates depend on specific HTS classification and trade program eligibility.
Identify the correct HTS code, look up the base MFN rate, check for additional layers (Section 301, 232, reciprocal, Section 122), then add MPF (0.3464%) and HMF (0.125% for ocean). Our calculator handles all of this automatically.
China imports face the base MFN rate plus Section 301 tariffs (7.5%-100% depending on product list), plus Section 122 (10%). The total varies significantly by product — steel from China could face 100%+ while some consumer goods face 17-30%.

Yes. A steel product from China could face: base MFN + Section 301 + Section 232 + Section 122 + MPF + HMF. Our calculator automatically identifies and stacks all applicable layers for any HTS code and country combination.
