HS 300630 Opacifying preparations for X-ray examinations; diagnostic reagents designed to be administered to the patient
Quick Answer: Opacifying preparations for X-ray examinations and diagnostic reagents designed to be administered to patients imported under HS 300630 enter the UK at 0.00%, the EU at 0.00%, and the US at Free under the MFN rate. This classification covers substances used to enhance the visibility of internal body structures during medical imaging procedures, as well as ready-to-use diagnostic kits administered to patients for medical testing. Importers should note that while duty rates are currently nil in these major markets, specific import regulations, such as those pertaining to medical device registration or product safety, may still apply. CustomTariffs aggregates this duty information, highlighting the generally favorable trade conditions for these specialized medical products.

How to Classify This HS Code?
What products does HS 300630 cover?
This subheading covers opacifying preparations specifically formulated for X-ray examinations, such as barium sulfate suspensions used in gastrointestinal imaging, and diagnostic reagents designed to be administered to patients for diagnostic purposes. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes and definitions found in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC, these products are intended to aid in medical diagnosis by enhancing visibility during imaging or by reacting to specific physiological conditions, and are not intended for therapeutic use.
What falls outside HS 300630?
The following products are excluded from HS 300630: general laboratory reagents not designed for patient administration, contrast media for external use (e.g., ultrasound gels), therapeutic drugs, and medical devices that do not contain diagnostic reagents. For instance, sterile saline solutions for wound irrigation, disinfectants, or diagnostic test kits intended for in-vitro analysis (which would typically fall under HS 3002 or 3822) are not classified here. The key distinction is the intended administration to a patient for diagnostic purposes.
What are common classification mistakes for HS 300630?
A common error is misclassifying diagnostic reagents intended for in-vitro use under this subheading. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. Reagents for laboratory testing, even if diagnostic, are generally classified elsewhere, such as under HS 3822. Importers may also mistakenly classify therapeutic preparations or general medical supplies that do not fit the specific diagnostic and opacifying criteria of this code.
How should importers classify products under HS 300630?
The correct procedure for classifying products under HS 300630 involves a thorough review of the product's intended use, composition, and administration method. Importers and customs brokers must consult the official nomenclature, including the WCO HS Explanatory Notes, and the specific tariff schedule of the importing country (e.g., USITC HTS, EU TARIC). Verification of whether the preparation is an opacifier for X-ray or a diagnostic reagent administered to the patient is crucial for accurate classification.
How is the duty calculated for products under HS 300630?
A shipment of 100 bottles of Barium Sulfate Oral Suspension, each 500ml, declared at a customs value of $1,500 USD, would attract a US duty. Assuming a Most Favored Nation (MFN) duty rate of 5% ad valorem as per the USITC Harmonized Tariff Schedule, the duty would be $75.00 USD (5% × $1,500). This calculation is based on the declared value of the goods, as the MFN rate for this specific product is typically ad valorem.
Which trade agreements reduce duties for HS 300630?
Several free trade agreements may reduce the applicable duty rate for HS 300630, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for originating goods from Canada and Mexico. Additionally, the Generalized System of Preferences (GSP) may offer duty-free entry for originating goods from certain developing countries, such as India. To claim these preferences, a valid origin declaration or certificate, such as a USMCA Certificate of Origin or a GSP Form A, is typically required by customs authorities.

FAQ
What are the import duty rates for HS code 300630 in the United States?
Under the Harmonized Tariff Schedule of the United States (USHTS), products classified under HS code 300630 are generally subject to a duty rate of Free. This applies to most favored nation (MFN) imports. It is crucial for importers and customs brokers to verify the specific country of origin, as preferential duty rates under Free Trade Agreements (FTAs) may also apply, potentially leading to the same Free status or other benefits. Always consult the latest USITC tariff schedule for definitive rates.
How is the duty calculated for HS code 300630 if it were dutiable?
While HS code 300630 is typically Free in major markets like the US, let's illustrate a hypothetical calculation. If a product under this code had a dutiable value of $10,000 and a hypothetical ad valorem duty rate of 5%, the duty would be calculated as: $10,000 (value) × 0.05 (duty rate) = $500. In practice, for this specific code, the duty amount is usually $0 due to its Free status in many jurisdictions.
What documentation is typically required for importing goods under HS code 300630?
For HS code 300630, importers and customs brokers should be prepared to provide a commercial invoice, a packing list, and a bill of lading or air waybill. Crucially, a certificate of analysis (CoA) or product specification sheet is often required to substantiate the product's identity and intended use as an opacifying preparation for X-ray examinations or a diagnostic reagent. Depending on the importing country's regulations, additional health or sanitary certificates might be necessary. Always check the specific import requirements of the destination country.
Are there specific classification criteria that distinguish HS code 300630 from other diagnostic or medical supplies?
Yes, the key classification criteria for HS code 300630 are its specific function and administration. 'Opacifying preparations for X-ray examinations' must be substances that enhance the visibility of internal body structures in radiographic imaging. 'Diagnostic reagents designed to be administered to the patient' are specifically intended for in-vivo diagnostic use to elicit a physiological response or provide diagnostic information. Products not meeting these criteria, such as laboratory diagnostic reagents not administered to the patient or general medical supplies, would fall under different HS codes.
Do trade agreements significantly impact the import duties for HS code 300630?
For HS code 300630, which often carries a Free duty rate under the Most Favored Nation (MFN) status in many countries, trade agreements may not always result in a further reduction of duty. However, they can still be significant. For instance, agreements like the USMCA (United States-Mexico-Canada Agreement) or EU trade deals can streamline customs procedures, reduce non-tariff barriers, and ensure consistent application of Free trade status. Importers and customs brokers should always confirm the origin of the goods and consult relevant FTAs to ensure full compliance and benefit from any applicable provisions.
