Warehouse & 3PL Setup
How do I choose a 3PL warehouse partner as a foreign e-commerce brand entering the US?
Score candidates on five things: geographic coverage against where your customers actually are, native integration with your storefront and order systems, published accuracy and on-time-shipping SLAs with remedies, transparent per-unit pricing including receiving, storage, pick, pack and returns, and demonstrated experience importing for foreign-owned brands. Ask for references from brands of your size, not their largest logo. The cheapest per-order rate frequently loses money once storage minimums, receiving fees and returns handling are added.
Do I need a US entity before I can sign a warehouse or 3PL contract?
Most reputable 3PLs will contract only with a US entity, because they need a domestic counterparty for liability, insurance and credit purposes. A foreign company can sometimes contract directly or use a partner acting as importer of record, but it complicates insurance, customs and payment terms. In practice, entity formation should be running ahead of 3PL selection so contracting is not the thing that delays your first shipment.
What's the timeline to get US warehousing operational from overseas?
Six to ten weeks is realistic from decision to first inventory receipt, assuming the entity already exists. 3PL selection and contracting takes two to four weeks, systems integration and testing two to three weeks, customs and importer-of-record setup runs in parallel, and ocean freight adds three to six weeks in transit. Compress it only by starting entity, EIN and customs registration before the 3PL search, not by shortening integration testing.
What's the difference between a 3PL and setting up my own warehouse?
A 3PL is a variable-cost service: no lease, no racking, no US warehouse employees, and per-unit pricing that scales with volume, at the cost of control over process and packaging. Your own warehouse is fixed cost — lease, fit-out, equipment, staff and employment compliance — and only makes sense once volume is consistent and your handling requirements exceed what a provider will do. Almost every new entrant should start with a 3PL and revisit the question after a full year of demand data.
Customs & Compliance
What customs documentation do I need before my first US-bound shipment?
At minimum: a commercial invoice with accurate values and HTS classification, a packing list, a bill of lading or air waybill, a customs bond (single-entry or continuous), the importer of record's details and bond, and any agency-specific documentation your product category requires such as FDA prior notice or FCC declarations. Importer Security Filing must also be transmitted before ocean cargo is loaded. Missing or inconsistent paperwork is the most common cause of a first-shipment hold.
Do I need a US customs broker, or can my freight forwarder handle it?
Many freight forwarders are also licensed customs brokers, but not all — confirm the licence rather than assuming. The broker files your entry, classifies goods and calculates duties on your behalf. Even with a broker, legal responsibility for accuracy stays with the importer of record, so review classifications and valuations yourself rather than treating the broker's work as a black box.
What product compliance checks catch foreign brands off guard at US customs?
Category regimes that differ from UK and EU rules: FDA requirements and prior notice for food, supplements, cosmetics and devices; FCC for electronics with radio components; CPSC certificates and tracking labels for children's products; FTC textile and country-of-origin labelling; and California Proposition 65 warnings. EU CE marking carries no weight in the US. Labelling in particular has to be corrected before manufacture, not after arrival.
How do tariffs and duties affect landed cost planning for US fulfillment?
Duty is assessed on the HTS classification and declared customs value, and rates vary widely by category and country of origin, with additional Section 301 or antidumping duties on some goods. Landed cost must include duty, merchandise processing and harbor maintenance fees, brokerage, freight, insurance and drayage — commonly 15% to 30% above ex-works cost. Price the US range from landed cost rather than from your home-market margin, or the first duty invoice will erase the margin.
Logistics Operations
How does inventory need to be structured across US warehouses for fast shipping?
One well-placed facility can reach most of the continental US in two to three days by ground; two nodes, typically one East Coast and one West Coast, get most of the population into a one-to-two-day band. Splitting inventory improves transit time and reduces zone-based shipping cost, but it raises safety stock, adds a second set of state registrations, and needs allocation logic in your order management system. Most brands should start with a single node and split once volume justifies it.
What's the cost difference between US-based 3PL and shipping direct from overseas?
Direct cross-border shipping avoids US storage costs but pays high per-parcel international rates, exposes customers to unpredictable duties, and delivers in one to three weeks. Bulk importing to a US 3PL moves freight at container economics and delivers domestically in two to three days. Domestic fulfillment usually wins on total cost once volume passes a few hundred orders a month, and it wins on conversion and returns experience well before that.
Do I need separate compliance steps for different US states' product regulations?
Yes for some categories. California's Proposition 65 warnings, state-level requirements for supplements, cosmetics and cleaning products, packaging and extended producer responsibility laws in several states, and state restrictions on specific ingredients or materials all apply on top of federal rules. Separately, holding inventory in a state creates sales tax nexus and often a foreign qualification obligation, so each new warehouse location is a compliance event as well as a logistics one.
Getting Started
What should a foreign brand do first: entity setup or warehouse setup?
Entity setup, in almost every case. The entity is a prerequisite for the EIN, the bank account, the customs bond and importer-of-record registration, and the 3PL contract itself. Warehouse selection can be researched in parallel, but signing and onboarding will stall without the entity. The one exception is a partner-as-importer-of-record arrangement for a small pilot shipment, which is a test, not an operating model.
Can Seal Global coordinate 3PL, customs, and compliance as one workstream?
Yes. Seal Global runs logistics as part of US market entry operations enablement, so entity, EIN, customs and importer-of-record setup, 3PL selection and contracting, product compliance review, state tax registrations and back-office support are sequenced by one team against one launch date. That avoids the usual failure mode where a freight forwarder, an accountant and a lawyer each complete their piece correctly and nobody owns the dependencies between them.
What happens if products fail a customs compliance check after arrival?
Customs can detain the shipment while you provide documentation, require relabelling or reconditioning under supervision, refuse entry and require export, or in serious cases seize the goods — with demurrage and storage accruing daily throughout. Penalties can apply for misdeclaration. Most detentions are resolved with corrected paperwork or labelling, but the cost is measured in weeks of delay, so pre-clearing category requirements before manufacturing is far cheaper than fixing it at the port.
