What Duty-Free Actually Means on Your Next Production Run (And Why Most Brands Are Still Paying Tariffs They Don't Have To)

If you're importing finished apparel into the United States right now, duty-free garment manufacturing under the Colombia-U.S. trade agreement is probably saving your competitors money while you're still writing cheques to U.S. Customs. That's not a guess. The math is straightforward, and we're going to walk through it category by category, price tier by price tier, so you can see exactly what you're paying and what you don't have to pay.

What the Colombia-U.S. Trade Promotion Agreement actually covers for finished apparel

The Colombia-U.S. Trade Promotion Agreement, known as the CTPA, came into force in May 2012. Under it, most finished apparel categories enter the United States at 0% duty. That covers woven shirts, knit tops, trousers, jackets, dresses, activewear, and a wide range of accessory and outerwear categories. Not everything, but most of what a typical U.S. apparel brand actually produces.

The zero-duty rate isn't automatic, though. It requires that the goods meet the agreement's rules of origin. For apparel, the CTPA uses a yarn-forward standard, which we'll explain in detail in a later section. The short version: the yarn has to come from a qualifying country, meaning Colombia or the United States, and the fabric has to be woven or knit from that yarn in one of those two countries.

The preference is claimed at the U.S. port of entry using a Certificate of Origin. This is a document your factory prepares before the shipment leaves. If you don't have it before the goods ship, you cannot claim the preference after the fact. Customs won't let you amend a cleared entry to recover duties you already paid. This is one of those details that seems administrative until it costs you $3,000 on a single shipment.

What U.S. brands are currently paying in tariffs on garments from Asia in 2026

This is where the conversation gets uncomfortable if you're still sourcing from China. Standard MFN duty rates on apparel from China were already in the 12% to 17% range before any additional measures. Section 301 tariffs, which were introduced in stages starting in 2018 and have been modified and extended since, stack on top of those MFN rates. As of mid-2026, the effective combined tariff on finished garments from China runs approximately 32% to over 50% depending on the HTS category.

A woven cotton shirt under HTS 6205 carries a base MFN rate of roughly 19.7%. Add Section 301 tariffs of 25% to 30% on top, and you're looking at an effective rate of 44% to 50% on the FOB value. For a knit top under HTS 6109, the numbers are similar. Synthetic-heavy categories can run even higher.

Vietnam and Bangladesh carry lower tariff exposure than China, but neither country has a free trade agreement with the United States. Standard MFN rates apply, generally 12% to 17% on woven apparel and 16% to 20% on certain knit categories. Not as punishing as China, but not zero either. Colombia is zero.

The per-unit duty savings at three different wholesale price tiers

Let's put real numbers on this. We'll use a woven shirt as the example because it's a common category and the tariff math is easy to follow. Assume the same garment, same construction, produced in two different origins.

Tier 1: $8 FOB woven shirt

At a 40% effective tariff rate from China, the duty on an $8 FOB shirt is $3.20 per unit. From Colombia with CTPA-qualifying fabric, the duty is $0. That's $3.20 per unit saved. On a 500-unit order, that's $1,600 back in your pocket before you've calculated a single dollar of freight savings.

Tier 2: $12 FOB woven shirt

This is the tier where the numbers start to move the needle for most mid-market brands. At a 40% effective tariff, a $12 FOB shirt from China carries $4.80 in import duty. At 45%, it's $5.40. At 50%, it's $6.00. So you're paying $4.80 to $6.00 per unit before ocean freight, insurance, customs brokerage, or any domestic logistics costs touch the shipment. From Colombia at 0%, you pay none of that. On a 500-unit order at the 40% rate, that's $2,400 saved on duty alone. At 50%, it's $3,000.

Tier 3: $22 FOB outerwear or structured jacket

Move into a more constructed category and the stakes are higher. At a 40% effective rate, a $22 FOB jacket carries $8.80 per unit in duty from China. At 50%, it's $11.00. On a 300-unit order, that's $2,640 to $3,300 in tariff costs, entirely avoidable with a CTPA-qualifying Colombian supplier. And that's a 300-unit order. Scale it to 1,000 units and you're talking about $8,800 to $11,000 per production run, just in duties.

Why the landed cost calculation has to include freight, insurance, and compliance costs, not just tariffs

A lot of brands stop the comparison at the FOB price plus tariff and call it done. That's not landed cost. Landed cost is what the unit actually costs you when it's sitting in your U.S. warehouse, cleared and ready to pick. You have to add ocean freight, marine insurance, the tariff itself, customs brokerage, any port examination fees, domestic trucking from the port to your warehouse, and, increasingly, compliance costs related to documentation and origin verification.

Ocean freight from China to the U.S. West Coast or East Coast on a full container runs roughly $3,000 to $5,500 per 40-foot container in current market conditions, though this has been volatile. On a small order where you're consolidating into an LCL shipment, your per-unit freight cost can run $1.50 to $4.00 depending on how dense your product is and how much cubic volume it takes. Marine insurance adds another 0.3% to 0.5% of the cargo value.

If lead times force you to air freight, the calculus gets painful fast. Air freight from Asia to the U.S. runs $3.50 to $6.00 per kg depending on the carrier and lane. A woven shirt might weigh 0.4 to 0.6 lb per unit. A jacket could run 1.5 to 2.0 lb. Do the maths. Air freight on a jacket from Asia can add $3.00 to $5.50 per unit on top of everything else.

Where the duty-free benefit breaks down: yarn-forward rules and fabric origin requirements

Here's the honest part. The 0% duty rate under the CTPA is not available for every garment made in Colombia. It's only available for garments that meet the yarn-forward rule of origin. That means the yarn used to make the fabric must have been produced in Colombia or the United States, the fabric must have been woven or knit from that yarn in Colombia or the United States, and the garment must then be cut and sewn in Colombia.

If your design calls for a specific fabric that's only available from a Chinese or Taiwanese mill and you want that exact fabric used as-is, the finished garment will not qualify for duty-free treatment. The garment is sewn in Colombia, yes, but the yarn-forward chain is broken. Your broker will have to enter the goods at the applicable MFN rate, which for most categories is 12% to 17%.

This matters more in some categories than others. Basic jersey knits, many wovens, fleece, French terry, canvas, twill, and poplin are all widely produced in Colombia using domestic or U.S.-origin yarn, and qualifying fabric is generally available. Technical fabrics, specialty prints, and highly processed synthetics are where you're more likely to run into an origin problem.

There is also a tariff preference level, or TPL, provision in the CTPA that allows a certain quantity of apparel made from non-qualifying fabric to still enter at preferential rates. But TPL allocations are finite, quota-limited, and require coordination between your customs broker and the relevant U.S. government authority. It's not something you can rely on as a default. Sort out the fabric origin before the order is placed, not after.

How 4-6 week lead times change the cash flow equation compared to 16-week ocean shipments from Asia

Tariffs get the headline, but lead time is where the cash flow story lives. From Barranquilla, it's roughly four sailing days to the Port of Miami. Factor in production time of four to six weeks and you're looking at a six to seven week total cycle from order confirmation to goods cleared at a U.S. port. From China or Vietnam, a 16 to 20 week total cycle is common, sometimes longer when you factor in pre-production, production, and 18 to 25 sailing days on the water.

What that means in working capital terms: when you're shipping from Asia, you're paying for your inventory roughly 14 to 16 weeks before you can sell it. From Colombia, it's six to seven weeks. The difference is tied-up cash that you can't spend on marketing, reorders, or the next development round.

On a 300-unit order at a $35 retail price, the wholesale value of the inventory in transit might be $5,000 to $7,500. If that inventory is sitting on a boat for 25 days rather than four, you're effectively carrying an extra three weeks of inventory finance cost. For most small to mid-sized brands, that's $1,800 to $2,500 in opportunity cost per order cycle, and it compounds across multiple orders per year. It's not a line item on an invoice, so brands tend to ignore it. They shouldn't.

What a realistic side-by-side landed cost looks like for a 300-unit order in September 2026

Let's build a real comparison. Woven shirt, $12 FOB equivalent from both origins, 300 units. We'll use a 40% effective tariff on the China origin and 0% on the Colombia CTPA-qualifying origin. Freight and logistics estimates are based on current LCL rates and typical broker fees.

• FOB unit cost, both origins: $12.00
• Tariff, China (40% effective rate): $4.80 per unit / $1,440 total for 300 units
• Tariff, Colombia (CTPA, qualifying fabric): $0.00
• Ocean freight per unit, China LCL to East Coast: approx. $2.20
• Ocean freight per unit, Colombia to Miami: approx. $1.40
• Marine insurance per unit (both origins): approx. $0.10 to $0.15
• Customs brokerage, ISF, port fees, shared across 300 units: approx. $0.80 to $1.20 per unit both origins
• Landed cost per unit, China: approx. $19.90 to $20.40
• Landed cost per unit, Colombia: approx. $14.30 to $14.75

That's a difference of roughly $5.50 to $6.00 per unit at this price tier. On 300 units, the total landed cost difference is approximately $1,650 to $1,800 in favour of Colombia. And that's before accounting for air freight risk if the Asia order runs late, before accounting for the carrying cost of the extra weeks of inventory in transit, and before accounting for any reorder agility you gain from shorter lead times.

If the CMT price in Colombia is $1.00 to $1.50 per unit higher than an equivalent Asian supplier, which is sometimes the case and sometimes not, the tariff saving alone more than covers it. The landed cost is still lower from Colombia, and you get six weeks instead of eighteen.

When the tariff savings alone are not enough to justify the switch, and what else has to be true

We'll be straight with you: there are situations where the numbers don't add up for a Colombia switch, and it's worth knowing what those are before you commit to anything.

If your order volume is very large, say 10,000 to 50,000 units per style per season, and you've built deep relationships with an Asian factory that has proprietary equipment, specialised finishing lines, or fabric exclusivity agreements that you'd lose by switching, the transition cost can outweigh the per-unit savings. Colombian factories, including ours, scale well up to certain volumes, but if you need a single factory to produce 30,000 units of a single SKU in six weeks, have that conversation directly and get capacity confirmed in writing.

If the fabric your design genuinely requires doesn't exist in a CTPA-qualifying origin and the TPL provision isn't available or practical, you'll enter at MFN rates, not zero. That changes the calculation. Run the landed cost with MFN rates applied before you assume the tariff benefit applies.

And if your business runs on 90-day payment terms with an Asian factory you've been using for years, switching to a new supplier in any country requires rebuilding that relationship and those terms from scratch. That's a real friction cost even if the landed economics look better on paper.

What has to be true for Colombia to make sense? The fabric can be sourced or substituted to meet yarn-forward compliance. Your order sizes fit within the 50-to-10,000-unit production range. The shorter lead time is something your business can actually use, whether that means fewer stockouts, less air freight, or more frequent reorders. And your landed cost calculation, done honestly with all line items included, shows a net benefit. If all four of those things are true, the switch isn't a leap of faith. It's just maths.
