What Are the US Import Requirements for Linen Clothing?

The Three Requirement Layers

US import requirements are easier to handle when they are split into the three layers above, because each one is owned by a different authority and each fails for a different reason. Customs rules decide whether and how the goods enter. Labelling rules decide whether the goods may be sold once they are inside. Product safety rules decide whether the goods are legal for their intended market. The wider process is covered in our guide to importing linen apparel into the US.

The reason the layers should be treated as separate workstreams is that passing one does not satisfy the others. Customs can release a shipment that still fails a labelling or safety check, and a perfectly labelled garment can still be held for a classification query. Building the file layer by layer, and reconciling it before departure, is what removes avoidable delay.

Classification and Duty: What the Code Decides

Classification starts with construction, not the style name. Knitted linen garments sit in Chapter 61 of the Harmonized Tariff Schedule and woven garments in Chapter 62, so two garments that look similar on a rail can sit in different chapters. Within the chapter the heading is set by garment type and gender, and only then does fibre decide the subheading, where flax has dedicated lines. On blends, the fibre that predominates by weight generally decides the classification, which means the composition in the specification is also the composition that drives duty.

The headline number is the duty rate, but the rates themselves are product and origin specific, so this answer deliberately describes how each charge is built rather than quoting a figure that may be out of date. A ruling from CBP gives a written classification decision for a specific article and removes the argument for a repeat programme, which is often the cheapest certainty available. If you also import into Europe, the counterpart file is our guide to importing linen clothing into the EU, where the classification logic is similar but the labelling and chemicals rules differ.

Labelling: Fibre Content, Care and Origin

US labelling is enforced primarily by the Federal Trade Commission, and it is more prescriptive in one respect than many buyers expect: country of origin marking is compulsory for imported articles. Fibre content must be disclosed with recognised generic fibre names, with percentages shown in descending order by weight. A linen and cotton blend must name both fibres and their percentages, and any trade name for a fibre must be qualified so it does not mislead about the actual content.

Care labelling is also mandatory. Garments must carry care instructions covering the regular care needed for the useful life of the product, and those instructions must be accurate for the finished fabric. Woven linen typically shows a first-wash shrinkage of 3 to 7 percent, and a care label that invites a treatment the fabric cannot withstand creates returns. What to print, and why the wording has to match the finished garment rather than the greige fabric, is covered in our article on care labels and branding for linen garments and in the specific answer on what care instructions to put on linen clothing labels.

Country of origin marking is where the United States differs most sharply from the European Union. Imported goods must be marked with the English name of the country of origin in a conspicuous, legible and permanent way, normally on the garment itself. If the marking is missing or not permanent, CBP can require it to be marked, or a marking duty of up to ten percent of the value can apply unless the goods are exported, destroyed or marked under supervision. A compliant US label set should confirm the following before production, not after.

• Fibre composition disclosed with percentages, using recognised generic fibre names and descending order by weight.
• Care instructions that cover the regular care of the garment and match the finished fabric.
• Country of origin marked in English, conspicuously, legibly and permanently on the article.
• An identifier allowing the garment to be traced back to a responsible business.
• No claim the supply chain cannot substantiate, whether about fibre, certification or sustainability.

Children's Linen: CPSC and CPSIA

Children's apparel is regulated far more heavily than adult apparel in the United States, so a linen children's range cannot be treated as a smaller adult range. Applicable Consumer Product Safety Commission rules must be met, and where a mandatory standard applies the product needs a Children's Product Certificate based on testing by a CPSC-accepted laboratory. Children's sleepwear is subject to flammability standards, and the rules distinguish sleepwear from daywear, so the intended use of a garment changes its obligations.

Two further requirements apply across children's goods. Total lead content in children's products is restricted, and surface coatings on accessible parts are also restricted, which is where metal buttons, zips and trims become a risk. Children's products additionally require a permanent tracking label carrying information such as the manufacturer or private labeler, the production location and date, and a batch or run identifier, so the item can be traced in a recall. None of these is optional, and none can be retrofitted cheaply. The material, trim and construction questions specific to children's linen are covered in our article on linen clothing for kids and baby; the practical rule is to decide at the tech pack stage whether a style is children's wear and to budget the testing and tracking label from the start.

Restricted Substances and Proposition 65

The United States has no single federal chemicals framework equivalent to the EU's REACH, which is the key structural difference for a brand selling in both markets. Federal law does restrict certain substances, and specific product rules apply, but much of the commercial pressure on apparel comes from state law. California's Proposition 65 is the most influential, because it requires a clear and reasonable warning before exposing consumers to listed chemicals above stated thresholds, and the list is long and regularly updated.

The substances that matter in practice are a familiar set: certain azo dyes, formaldehyde residues, heavy metals in dyes and trims, and in some cases phthalates. The evidence route is a restricted substance test on the actual material and trims used in production, not a generic certificate for a fibre family. OEKO-TEX Standard 100 is widely recognised as a practical screening framework, and a written restricted substance statement from the supply chain supports it. Measured certification is the difference between a claim you can defend and one you have to withdraw, and quality systems underpin it. How certification is verified is covered in our overview of linen manufacturer certifications, and how inspection confirms what was shipped is set out in our guide to linen garment quality inspection.

Entry Documents and Data

Entry is data driven: the description, the weights, the consignee and the value must agree across every document, because inconsistency is what triggers queries. The factory controls the invoice and packing list, the forwarder controls the transport document, and the importer of record controls the entry, which is why the file should be reviewed as a whole before the shipment departs.

The timing of this review depends on the production calendar. Sampling, bulk production and shipping each have their own windows, and documentation should be prepared in parallel rather than after the goods are finished. The sequence is set out in our overview of linen clothing lead times.

Most US entry problems come from a short list of routine omissions rather than exotic requirements. Checking for these before the shipment departs is one of the highest-value habits an importer can build.

1. A commodity code missing from the commercial invoice, forcing classification from a marketing description.
2. A consignee name that does not match the importer of record on the entry.
3. Label artwork that omits the permanent country-of-origin marking, or shows the wrong English origin text.
4. Care instructions that do not match the finished, pre-shrunk fabric.
5. A test report that covers a different material or colourway from the one shipped.
6. Weights that disagree between the invoice, the packing list and the carrier records.
7. An Incoterm that is not stated on the invoice, leaving clearance responsibility ambiguous.
8. A children's style without the required testing, certificate or tracking label.

Getting a Linen Order Through US Customs Step by Step

The sequence below is the practical path from a finished order to a released shipment. Each step has an owner, and most delays come from a step being skipped and discovered late.

Two points sit outside this line. The first is compliance evidence, which is collected during production rather than at entry. The second is the delivery term, which decides who performs steps two, four and six. The practical comparison of delivery terms is set out in our answer on Incoterms when importing linen clothing.

A Pre-Shipment US Compliance Checklist

Before a US-bound linen shipment leaves the factory, confirm each of the following. No single item is difficult, and together they remove almost every avoidable border delay.

How a Factory Supports Your US Import

Understanding what a factory can prepare and what stays with you or your agent prevents most document delays. A good factory produces clean commercial documents and compliance evidence; the transport and entry documents sit with the forwarder and the importer.

If you want to see how these requirements sit within the wider import process, the guide linked above covers classification, duty, Section 301, labelling and the DDP versus DAP decision end to end.
