Live animals, animal products, plants and plant products are subject to quarantine regulations. Marking of Goods and Packages All goods should be marked with an indication of origin if they bear any trademarks or words in the English language. Markings indicating quantity, weight, measurements, trade descriptions, component materials or purity of the product must be accurate. All dyes, chemicals and pharmaceuticals products should be marked with a full description of the products, including quality and code numbers. Dangerous or poisonous drugs and medicines must be marked to show the ingredients.
Special regulations govern the marking of patent or proprietary medicines.
Piece goods, sold by the length or by piece, made wholly or partly of cotton or wool, must also be marked with the yardage. Packages should bear the consignee's mark, including the port mark, and they should be numbered unless the shipment is such that the contents of the packages can be readily identified without them.
