How to Choose a Freight Forwarder When Sourcing Products Internationally
A freight forwarder coordinates the movement of your goods from the factory to the warehouse, handling carrier booking, documentation, customs clearance, and last-mile delivery. If you are sourcing products from Vietnam, Mexico, or other parts of Asia, choosing the right forwarder directly affects your landed cost, delivery timeline, and whether your shipment clears customs without delay. We help thousands of clients navigate this decision every year, and the mistakes we see most often happen before a single container is booked.
What a Freight Forwarder Actually Does (and Does Not Do)
Freight forwarder vs. customs broker vs. shipping line
A freight forwarder is your logistics coordinator. They do not own ships or planes. They book space with ocean carriers and airlines on your behalf, arrange pickup from the factory or port, handle export and import documentation, and coordinate delivery to your door, Amazon FBA center, or warehouse. A customs broker handles specifically the import clearance at your destination: classifying your goods, filing entries, and ensuring you pay the correct duties and taxes. Many forwarders offer in-house customs brokerage, but it is a separate function. The shipping line (Maersk, MSC, CMA CGM, etc.) operates the vessel. You can book directly with a shipping line, but most importers use a forwarder because the forwarder handles everything beyond the carrier's ocean transit.
What "door-to-door" actually means in practice
When a forwarder quotes "door to door," they mean factory pickup through final delivery. In practice, that quote rarely includes customs duties and taxes at your destination, and often excludes terminal handling charges, chassis fees, and warehouse delivery appointments. Always ask the forwarder to itemize what is and is not included in a door-to-door quote. The number you see on the first quote is rarely the number you pay at the end.
When you need a forwarder vs. when your factory's shipping terms cover it
This depends entirely on your Incoterms. If you are buying FOB (Free On Board), the factory delivers your goods to the export port, and everything from that point forward is your responsibility. You need your own freight forwarder. If your supplier is shipping DDP (Delivered Duty Paid), the seller handles the entire logistics chain to your door. In that case, you technically do not need a forwarder, but you lose visibility into shipping costs and control over carrier selection, which creates its own set of risks.
Should You Use Your Factory's Forwarder or Find Your Own?
This is one of the most common questions we get from clients after they have found a manufacturer, and the answer is not always obvious.
When using the factory's forwarder makes sense.
If you are shipping a small order (a few cartons by air or a partial container), the factory's forwarder often offers better consolidation rates because they bundle your shipment with other orders leaving the same region. For DDP shipments in which the supplier covers all logistics costs, the factory will use its own forwarder by default. This can work well when the supplier is large and established, and has a legitimate logistics partner.
When you need your own forwarder
Once you are shipping FOB, buying from multiple factories in the same country and consolidating cargo into one container, or shipping full containers regularly, you should have your own forwarder. You will get better rate visibility, direct communication on delays and documentation, and the ability to compare quotes independently if you are importing from multiple suppliers in Vietnam and want to consolidate everything into one shipment out of Cat Lai port. Your own forwarder handles the consolidation warehouse, the container loading plan, and the single bill of lading.
The hidden risk of letting your supplier control the logistics
When the factory controls the forwarder, you have no independent verification of what you are paying for freight versus the actual market rate. We have seen cases where suppliers mark up the shipping quote by 20% to 40% and present it as a pass-through cost. You also lose leverage if something goes wrong. If the shipment is delayed or the goods arrive damaged, your factory and your logistics provider are the same entity (or close business partners), and neither has an incentive to take your side. Having your own forwarder creates an independent set of eyes on the cargo from the moment it leaves the factory.
How Freight Forwarding Pricing Works
Ocean freight pricing: per container (FCL) vs. per cubic meter (LCL)
Full Container Load (FCL) is priced per container. A 20-foot container from Ho Chi Minh City to the US West Coast typically runs $1,500 to $3,500, depending on the carrier and season. A 40-foot container runs roughly 30% to 60% more than a 20-foot container on the same lane. Less than Container Load (LCL) is priced per cubic meter (CBM). Rates from Vietnam to the US typically range from $40 to $100 per CBM, plus handling surcharges. LCL makes sense for shipments under about 15 CBM. Above that threshold, it is usually cheaper to book an FCL even if the container is not full.
Air freight pricing
Air freight is priced per kilogram, but carriers use either actual weight or dimensional weight (volume divided by a standard factor), whichever is higher. Rates from Vietnam to the US generally range from $3 to $8 per kilogram, depending on volume, urgency, and whether you are using standard air freight or an express courier. Air freight makes sense for samples, urgent restocks, and high-value, low-weight products like electronics accessories.
The fees that always show up after the quote
This is where most first-time importers get caught. The initial freight quote covers the ocean or air transport. The final invoice includes a list of additional charges that were either buried in the fine print or not mentioned at all. Common ones include: terminal handling charges at the origin and destination port ($150 to $400 per container), documentation fees ($50 to $150 per shipment), customs examination fees if your container is flagged for inspection, demurrage charges if your container sits at the port beyond the free days (typically 3 to 5 free days, then $75 to $250 per day), detention charges if you hold the container beyond the free period after pickup, and delivery surcharges for residential or limited-access locations. A good forwarder discloses all of these upfront. A bad one gives you a low base rate and makes up the difference with destination charges.
Why the cheapest quote is usually not the cheapest shipment
The forwarder with the lowest ocean freight rate often has the highest destination charges, or does not include fuel surcharges and peak season adjustments. Always compare the total landed cost of each quote, not just the line-item freight rate. Ask every forwarder for an all-in estimate that includes origin charges, freight, destination charges, customs brokerage, and delivery.
How to Evaluate a Freight Forwarder
Do they specialize in your trade lane?
A forwarder who ships 500 containers a year from Vietnam to North America has better carrier relationships, faster issue resolution, and more accurate transit time estimates on that lane than a generalist who covers 40 countries. Ask how many shipments they handle per month on your specific route. If you are sourcing from Vietnam, refer to our list of Vietnamese freight forwarders as a starting point.
Origin vs. destination forwarder: which should you hire?
An origin forwarder (based in Vietnam or Mexico, near your factories) handles export-side logistics and has direct relationships with local carriers and ports. A destination forwarder (based in your country) handles the import side and knows your local customs regulations. For most importers, the best setup is a forwarder with offices or agents on both ends. If you have to choose one, start with an origin forwarder for your first few shipments, because the most common problems (factory delays, documentation errors, missed vessel bookings) happen on the export side.
What to ask before signing
Go beyond "how much experience do you have?" and ask questions that reveal how they actually operate: What is your all-in cost estimate from factory door to my warehouse, with every fee itemized? How many shipments do you handle per month on this specific trade lane? What happens if my container misses the vessel or gets held at customs? Who is my day-to-day contact, and what are your response times? Can you provide references from other importers on this lane?
Red flags to watch for
Be cautious if a forwarder offers rates significantly below competitors without explaining why, cannot clearly explain Incoterms or how duties are calculated, quotes vague "destination charges TBD" without itemizing, has no tracking or shipment visibility platform, or requires full payment upfront before booking.
Vietnam and Mexico Shipping Considerations
What to know about shipping from Vietnam
Vietnam's two main export ports are Cat Lai (in the Ho Chi Minh City area, serving the southern manufacturing hub) and Hai Phong (serving the north). Most furniture, garments, and consumer goods ship out of Cat Lai. Transit time from Cat Lai to the US West Coast is typically 14 to 18 days by ocean; to the East Coast, 25 to 30 days. For a deeper look at the full logistics process, see our guide to shipping from Vietnam. For an overview of import duties and customs procedures, see our tariffs and customs guide.
What to know about shipping from Mexico
Mexico-to-US shipments are often faster and cheaper than ocean freight from Asia because of the land border. Many products move by truck through border crossings at Laredo, El Paso, or Nogales. Cross-border trucking from northern Mexico to a US warehouse can take 2 to 5 days. If the product qualifies under USMCA rules of origin, it enters duty-free, which significantly lowers the landed cost. Your forwarder needs to understand USMCA documentation requirements, country-of-origin rules, and the difference between a customs broker at the border and an inland delivery carrier.
When to consider air freight vs. ocean
Use air freight for sample shipments (always), urgent restocks where being out of stock costs more than the shipping premium, and high-value, low-weight products where ocean freight savings are minimal relative to the product cost. For everything else, ocean freight is almost always the better value. A single 40-foot container holds roughly the same volume as 30 to 40 air freight pallets at a fraction of the cost.
