Customs and Import Compliance

What is an importer of record and why does a foreign e-commerce brand need one?

The importer of record is legally responsible for customs compliance, duties and product safety documentation when goods enter the US. A foreign company without a US entity typically needs a customs broker or US-based partner to act as importer of record before inventory can legally clear customs.

Do all products need certification before entering the US?

Requirements vary by category — electronics, cosmetics, food and children's products each have their own compliance regimes (FCC, FDA, CPSC, and others). Checking category-specific requirements before the first shipment avoids customs holds or costly recalls later.

What happens if a shipment is held at customs?

Holds usually happen due to missing documentation, incorrect tariff classification, or incomplete importer-of-record paperwork. Resolution can take days to weeks and often requires a licensed customs broker.

Can a 3PL provider also act as an importer of record?

Some offer this as an add-on or partner with a customs broker, but it's not universal — ask this upfront, since assuming it's included when it isn't can delay the first shipment by weeks.

Choosing a 3PL vs. Owned Warehouse

Should a foreign e-commerce brand use a 3PL or lease its own warehouse?

Most start with a 3PL because it requires no long-term lease, no US warehouse staff to hire, and scales with order volume. Owned/leased warehousing usually only makes sense once volume is consistent enough to justify fixed costs.

How many 3PL locations does a new entrant typically need?

Most start with a single location, often near a major port or population center, and add regional locations as order volume and delivery-speed expectations grow.

What should we compare when evaluating 3PL providers?

Pick/pack pricing, storage cost per unit, integration with your order management platform, carrier relationships and shipping rates, returns handling, and support for your specific product category.

How long does it take to get a 3PL relationship live?

Typically two to four weeks from contract signature to first shipment received, assuming systems integration is straightforward; custom integrations can extend this.

Sales Tax and Legal Triggers

Does storing inventory in a US warehouse create a sales tax obligation?

In most states, yes — physically storing inventory, including at a 3PL's warehouse, creates "nexus," generally requiring sales tax registration and collection in that state regardless of where your entity is incorporated.

Which states are most commonly triggered by 3PL warehouse locations?

This depends on where your 3PL operates — popular hubs like California, Texas and New Jersey each have their own registration and filing requirements once nexus is triggered.

Do we need product liability insurance before shipping to US customers?

Most 3PLs and marketplaces require proof of product liability insurance before handling or listing your inventory, and US courts are a materially higher liability environment, so this is generally not optional for physical goods.

What legal registrations come with warehousing that aren't obvious upfront?

Beyond sales tax nexus, some states require a "doing business" foreign qualification once you have a physical presence like a warehouse, separate from your state of incorporation.

Operations and Systems

What systems need to connect to a 3PL for day-to-day operations to work?

At minimum, your e-commerce platform, inventory management, and order routing need to feed the 3PL's warehouse management system in near real time so stock levels and shipping confirmations stay accurate.

How should returns and reverse logistics be handled?

Most 3PLs offer returns processing as an add-on — receiving, inspecting, restocking or disposing of returns — and this should be scoped and priced before go-live, since returns volume for new entrants is often underestimated.

What's a realistic timeline from decision to first US warehouse shipment?

Allowing two to four weeks for 3PL contracting/integration plus customs and importer-of-record setup, most foreign brands can expect six to ten weeks from decision to receiving inventory in a US warehouse.

Who typically manages the relationship between the brand, the 3PL, and customs compliance?

Usually whoever owns operations enablement for the US entry — often a back-office or operations partner — since it touches customs, tax nexus and fulfillment simultaneously; leaving it with marketing or sales alone tends to create gaps.
