How to Classify This HS Code?

```html

What products does HS 600631 cover?

This subheading covers knitted or crocheted fabrics of synthetic fibres, specifically those that are not pile or terry fabrics. According to the World Customs Organization's Harmonized System Nomenclature, this includes fabrics woven on knitting machines, such as warp knitting and weft knitting. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this category encompasses a wide array of synthetic textiles, excluding those with specific pile or loop constructions, and must be composed predominantly of synthetic fibers by weight.

What falls outside HS 600631?

The following products are excluded from HS 600631: knitted or crocheted fabrics of synthetic fibres that are pile fabrics (HS 600632), terry fabrics (HS 600633), or fabrics of other materials like cotton or artificial fibres. For instance, a knitted fleece fabric made primarily of polyester would fall under this subheading, but a knitted velvet fabric or a knitted towel fabric would be classified elsewhere. Fabrics with significant blends of other fibers, where synthetic fibers are not the predominant component by weight, would also be excluded.

What are common classification mistakes for HS 600631?

A common error is misinterpreting the "synthetic fibres" definition or overlooking the exclusions for pile or terry fabrics. General Rule of Interpretation (GRI) 1 states that classification shall be determined according to the terms of the headings and any relative section or chapter notes. Importers may incorrectly classify fabrics that are predominantly made of artificial fibres (e.g., rayon, viscose) under this subheading, when they should be classified under HS 600641. Additionally, confusing knitted fabrics with woven fabrics can lead to misclassification.

How should importers classify products under HS 600631?

The correct procedure for classifying products under HS 600631 involves a multi-step analysis. First, determine the predominant fibre content by weight; if it is synthetic, proceed. Second, confirm the fabric construction is knitted or crocheted, not woven. Third, verify that the fabric is not a pile or terry fabric. Consulting the official tariff schedule, such as the USITC HTS or the UK Trade Tariff, and reviewing the relevant chapter and heading notes is crucial. For example, a 100% polyester knitted jersey fabric fits this description.

How is the duty calculated for products under HS 600631?

A bolt of 100% polyester knitted interlock fabric weighing 50 kilograms and declared at a customs value of $500 USD would attract a US duty of $25.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value ($500 USD × 0.05 = $25.00). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule (HTS) for subheading 6006310000.

Which trade agreements reduce duties for HS 600631?

Several free trade agreements may reduce the applicable duty rate for HS 600631, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico. The UK's Generalized System of Preferences (GSP) may offer reduced or Free duties for goods from certain developing countries. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and jurisdiction.

Synthetic fibres include materials like polyester, nylon, acrylic, and elastane. The classification is determined by the fibre content, with the chief weight of the fibre dictating the classification if multiple fibre types are present.

Importers and customs brokers must ensure the COO is accurate, complete, and submitted within the required timeframe to avoid duty reassessment and penalties.
