Overview

Mexican entrepreneurs are increasingly purchasing goods from domestic manufacturers and shipping them to Amazon US fulfillment centers. This model lets sellers benefit from lower production costs while tapping into the expansive U.S. marketplace, but it also introduces requirements around customs paperwork, labeling, and tax compliance. Mastering each element can prevent costly delays and protect profit margins.

Key Points

• Cost advantage of local sourcing — Buying finished products in Mexico can shave 15 %–30 % off the unit price versus sourcing from overseas factories, especially for items such as home décor and apparel.
• Mandatory customs paperwork — Every cross‑border shipment must be accompanied by a commercial invoice, a packing list, and a USMCA certificate of origin to qualify for preferential duty treatment.
• Amazon FBA labeling remains unchanged — Products destined for U.S. fulfillment sites must carry Amazon‑generated FNSKU labels and meet the same packaging dimensions as domestic shipments.
• Duty rates vary by product class — The U.S. Harmonized Tariff Schedule assigns tariffs ranging from 0 % to 20 % depending on the HS code, so sellers need to factor duties into their pricing strategy.
• U.S. tax registration is required — Sellers must obtain an Employer Identification Number (EIN) and may need to register for sales‑tax collection in any state where Amazon stores inventory.
• Freight choice influences lead time and cost — Air freight can move a 500‑unit pallet from Guadalajara to California in 3‑5 days, while ocean freight adds 20‑30 days but reduces per‑unit shipping expense.

How Buying in Mexico and Selling on Amazon US Works

1. Product discovery — A seller in Puebla identifies a 12‑oz stainless‑steel water bottle that commands $22 USD on Amazon US and yields a 35 % margin after Amazon fees.
2. Local supplier negotiation — The seller secures a contract with a Monterrey manufacturer for 1,000 units at $8 USD each, a price roughly 25 % lower than comparable Chinese offers.
