Customs Clearance of Lysine and Its Esters

For an estimate of the time and cost to clear lysine and its esters, contact the Saba Tarkhis experts.

Animal Feed
Lysine is one of the most important essential amino acids in livestock and poultry nutrition and is widely used as a growth-promoting supplement. Adding lysine to rations improves muscle growth, increases feed conversion ratio (FCR), strengthens the immune system, and reduces mortality.
It also plays an effective role in optimizing ration formulation and prevents waste of protein resources. In broilers, layers, and fattening livestock, adjusting the lysine-to-methionine ratio is a key factor for achieving high performance.

Nutritional & Pharmaceutical Supplements
Beyond veterinary use, lysine is used in the production of human dietary supplements. It helps tissue repair, improves calcium absorption, boosts the immune system, and supports nitrogen balance in the body.
In veterinary applications, lysine-containing supplements are used to increase appetite, improve growth, and enhance the general condition of young or convalescent animals. Combining it with vitamin C or zinc can further improve absorption and efficacy.

Food Industry
In food processing, lysine is used as a protein-enrichment factor in various products such as energy drinks, flour products, infant formula, and baby food.
Adding lysine increases nutritional value, improves protein quality, and supplies essential amino acids.
Lysine is also used in producing certain amino-based additives and flavorings.

Lysine Esters in Pharmaceuticals
In the pharmaceutical industry, lysine derivatives and esters play a major role in enhancing absorption, stability, and efficacy of active ingredients. For example, lysine esters are used in the formulation of anti-inflammatory drugs, antivirals, and tissue-regeneration supplements.
These compounds help control drug release and improve bioavailability, and they are gaining attention in next-generation medicines.

Health/Veterinary/Standards Permits: Depending on end use, permits are required from the Veterinary Organization, Food and Drug Organization (Ministry of Health), and the National Standards Organization.

Labeling & Quality Documents: SDS, Certificate of Analysis (COA), and batch/lot information must fully match transport/commercial documents.

Common Countries of Origin: China, Germany, the Netherlands, and the United States are major global suppliers.

Exports from Iran: Currently limited; domestic demand (especially feed for livestock/poultry) is primarily met through imports.

 Commercial Invoice (CI)

The commercial invoice is one of the basic documents in the import process and includes a full description of the goods, tariff code (HS Code), FOB or CIF value, payment terms, and buyer/seller details. It is the primary basis for calculating customs duties and must fully match the order registration and the customs declaration.

 Bill of Lading (B/L) or Air Waybill (AWB)

The bill of lading is the title document for international carriage and includes the shipper, consignee, vessel/flight, number of packages, gross weight, ports of loading and discharge, and carriage terms.
For clearance, the B/L contents must be reconciled with the Packing List and the Commercial Invoice this is a core requirement for customs examiners.

 Certificate of Origin (CO)

The CO is issued by the chamber of commerce in the exporting country and shows in which country the goods were actually produced or assembled.
It is decisive for preferential tariffs, use of trade agreements, and verifying origin.

 Packing List

This lists the exact number of cartons or pallets, each package’s net and gross weight, dimensions, packaging type, and shipping marks.
During physical inspection, customs officers reconcile the packing list with the actual shipment.

 Certificate of Analysis (COA)

Usually issued by the manufacturer or an accredited laboratory, the COA states technical specifications such as purity percentage, moisture, heavy metals, microbiological attributes, and chemical parameters.
It is mandatory for chemical, food, pharmaceutical, and cosmetic raw materials.

 Health or Veterinary Certificate

For items related to animal feed, foodstuffs, dairy, meat, and other animal/plant products, a health or veterinary certificate from the country of origin is required. This certifies compliance with international sanitary standards.

 Food and Drug Organization (FDA/IFDA) Permit

For items used in pharmaceuticals, dietary supplements, essences, and specific chemical esters, an authorization from the food and drug authority is required.
This shows official approval for human/pharmaceutical use in the destination country.

 Customs Declaration

The customs declaration is an official document submitted by the importer or broker and includes full details of value, quantity, tariff (HS Code), country of origin, transport details, and commercial documents.
It forms the basis for assessing import duties, VAT, and legal permits.

Order Registration in the National Trade Single Window (NTSW)

The final—and one of the most important—steps is registering the order in Iran’s NTSW. Without a valid registration code, official clearance is not possible.
At this stage, all product details (HS Code, weight, value, country of origin, payment and shipment terms) must be entered precisely so that the import permit is issued.
