HS Code for T-Shirts: Complete Guide to 610910 for Cotton Apparel

Imagine your shipment of thousands of cotton T-shirts held at a major US port like Long Beach, all because of a misclassified HS code. Customs agents scrutinize the fiber content, labels, and construction, leading to delays that cost importers thousands in demurrage fees and missed sales opportunities. At FreightAmigo Services Limited, we've seen this scenario play out too many times in our Hong Kong hub, where Asia's apparel exports converge. But it doesn't have to be this way. This comprehensive guide to the HS code for T-shirts—specifically 610910 for knitted or crocheted cotton varieties—equips you with the knowledge to classify correctly, optimize duties, and streamline your supply chain.

Whether you're sourcing from Bangladesh or India for the US or EU markets, understanding the t-shirts HS code, t-shirt harmonized code, and nuances of cotton shirt HS code ensures compliance and cost savings. We'll break down the official nomenclature, global trade dynamics, logistics challenges, and strategic tips drawn from our hands-on experience handling high-volume apparel shipments.

This table highlights the dominant players in HS 610910 trade, based on OEC.world data updated March 2026. Bangladesh leads due to competitive manufacturing, but geopolitical shifts are rerouting flows.

Understanding HS Code 610910: Official Breakdown

The HS code for T-shirts, singlets, and other vests of cotton falls under Chapter 61 of the Harmonized System, which covers knitted or crocheted apparel. Specifically, heading 6109 addresses T-shirts, singlets, and vests, with subheading 10 designating those made of cotton. The full code—610910—is precise: it applies to items knitted or crocheted primarily from cotton yarns.

In the US Harmonized Tariff Schedule (HTS) for 2025-2026, this extends to 10-digit codes like 6109.10.00 for general cotton T-shirts, with further breakdowns such as 6109.10.00.04 for all-white T-shirts featuring short hemmed sleeves, hemmed bottoms, crew/round/V-necks, and no pockets, trim, or embroidery. Other subcodes cover singlets (6109.10.00.07) and thermal undershirts or underwear (6109.10.00.11 and beyond). These distinctions are critical, as USITC revisions from November 2025 emphasize them for enforcement.

Key classification rules include:

• Fiber Content: Over 50% cotton by weight qualifies under 610910; blends with polyester shift to 610990.
• Construction: Must be knitted or crocheted—woven cotton shirts fall under 6205.20.
• Design: Basic T-shirts, singlets, tank tops, and vests; excludes hoodies (6110) or dress shirts.

From our experience processing shipments from Chittagong to Rotterdam, misclassifying a cotton blend as pure cotton can trigger audits, holding cargo for weeks. We recommend always verifying via official binding rulings from customs authorities like US CBP.

Global Trade Landscape for Cotton T-Shirts

HS 610910 represents a massive segment of apparel trade, valued at $25-30 billion annually. With 4-5 billion items traded yearly—often at $2-5 per unit—it's high-volume, low-margin logistics at its core. Exports grew 5-7% year-over-year pre-2025 but flattened in 2024 amid tariffs and Red Sea disruptions.

Top importers mirror consumer markets:

Source: World Bank WITS (2023 data, stable into 2024). US imports alone require 500,000-1 million TEUs yearly, packed densely in 20-40ft containers holding 10,000-50,000 units.

Exporters are shifting: Nicaragua and Honduras gained 20-30% US share in 2024-2025 via CAFTA-DR for duty-free entry, bypassing China tariffs. We at FreightAmigo have rerouted many such shipments, leveraging our Sea Freight options from Central America to optimize costs.

Logistics Challenges in Shipping HS 610910 Goods

Apparel like cotton T-shirts demands efficient, compliant logistics. Primary routes include Asia to US (Bangladesh/India to LA/Long Beach/Savannah) and Asia to EU (to Rotterdam/Antwerp). Peak seasons—Q2/Q3 for back-to-school—overload ports like Mumbai and Chittagong, exacerbated by 2024-2025 Red Sea issues adding 10-20% to transit times and costs.

Customs holds are rampant due to textile enforcement: US CBP frequently audits fiber content, labels, and origin rules (yarn-forward for preferences). We've assisted clients where a 2% polyester blend shifted classification, inflating duties unexpectedly.

Sustainability adds layers—EU and US buyers demand traceability for recycled cotton, requiring detailed documentation. In our operations, we've integrated tools to handle this seamlessly.

Tariffs and Duties: Navigating 2024-2026 Changes

Tariffs significantly impact HS 610910:

• US: 16.5% MFN base; +15-25% on China (Section 301); 10% global baseline (IEEPA, Feb 2026).
• EU: 12% average; GSP+ preferences for Bangladesh.

Strategic rerouting to Nicaragua avoids duties. To estimate precisely, our Duties & Taxes Calculator provides instant insights based on origin, HS code, and value—vital for budgeting $4-5K/TEU shipments.

Our Customs Clearance service uses AI-driven HS code validation to prevent errors, optimizing duties and ensuring compliance across 250+ countries.

Classification Best Practices and Common Pitfalls

Accurate HS classification starts with product specs:

1. Lab Testing: Verify cotton content via certified labs for blends.
2. Documentation: Include invoices, packing lists, and mill certificates stating 'knitted cotton T-shirts, HS 610910'.
3. 10-Digit Precision: For US, use subcodes; request advance rulings.

Pitfalls include confusing knitted (6109) with woven (6205), or ignoring neckline/sleeve specifics for white T-shirts. In one case we handled, a client faced 16.5% extra duties on $500K shipment due to unlisted trim—resolved via reclassification but at high cost.

Country-of-origin matters: Bangladesh qualifies for preferences if yarn-forward rules met. Tools like our Customs Clearance platform automate this verification.

Optimizing Supply Chains for T-Shirt Imports

Streamline with consolidated hubs: Ship FCL from Bangladesh to US West Coast, then truck to distribution. For LCL, our Track & Trace ensures visibility. Finance via Digital Trade Finance bridges cash flow gaps in high-volume trades.

2025-2026 outlook: Tariffs stabilize, but monitor US expansions (10-15% global). Volumes hold at 2B+ US units; sustainability drives recycled cotton under same code.

Real-World Case Studies from Our Experience

A European importer shifted from China to India for HS 610910, cutting duties 8% via GSP and saving 15% on freight using our Sea Freight consolidations. Transit: 35 days Mumbai-Rotterdam.

US retailer from Bangladesh avoided holds with pre-validated HS codes, clearing Savannah in 3 days versus industry 10-day average.

These successes stem from proactive classification and our integrated platform.
