Animal Quarantine and Certification Service: Border Control Explained

An animal quarantine and certification service is a government border-control system that holds imported livestock for observation and testing, and issues official veterinary health certificates for export. In India, that role is filled by the Animal Quarantine and Certification Services (AQCS) under the Department of Animal Husbandry and Dairying. As of September 2026, similar functions worldwide follow World Organisation for Animal Health (WOAH) standards and national agencies such as the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS).

This article answers the informational search for how quarantine and certification work at borders, who issues clearances, and how private digital livestock identity tools—such as the Animal Passport biometric record—relate to, but do not replace, official schemes.

What is an animal quarantine and certification service?

By definition used by India's AQCS, quarantine is detention and segregation for observation and testing for a prescribed period of livestock and livestock products imported or meant for export. Certification is the official veterinary attestation that animals or products meet the importing country's animal-health requirements.

The Food and Agriculture Organization of the United Nations (FAO) has long framed quarantine as all restrictions on the movement of infected or suspect animals or material to prevent disease spread, and has advised that quarantine establishments sit near ports or airports, be animal-proof, and avoid contact with farms, markets, or abattoirs. Those design principles still underpin modern border stations.

Two jobs sit under one institutional umbrella in many countries:

• Import quarantine and clearance — inspect documents and animals, hold consignments under biosecure conditions, sample and test, then release, hold, deport, or destroy as required by law.
• Export certification — after examination (and pre-export quarantine or testing when required), issue an international veterinary certificate that the destination country will accept.

India's Animal Quarantine and Certification Services (AQCS)

For searchers using the exact phrase animal quarantine and certification service, the primary named entity is often India's AQCS. The Government of India started the Animal Quarantine & Certification Services scheme during the Fourth Five Year Plan (1969–70). AQCS now operates under the Ministry of Fisheries, Animal Husbandry and Dairying, Department of Animal Husbandry and Dairying.

According to AQCS (as published on its About pages), the service's purpose is to prevent ingress of dangerous exotic diseases through imported livestock and livestock products, and to provide internationally acceptable certification for exports that matches importing-country requirements and WOAH procedures.

Where are AQCS stations?

AQCS states there are six stations: New Delhi, Mumbai, Kolkata, Chennai, Bangalore (Bengaluru), and Hyderabad. The Department of Animal Husbandry and Dairying Trade Division confirms that imports of animals and animal products are allowed through the sea ports and air ports of Bangalore, Chennai, Delhi, Hyderabad, Kolkata, and Mumbai where animal quarantine and certification services are available. Separate routes apply for certain fish products (for example, Visakhapatnam, Kochi, and Petrapole for Bangladesh fish trade).

AQCS FAQ answers state that the service works on a Single Day Decision Policy (SDDP) for many clearances and certificates, while noting that testing timelines and post-import quarantine still follow the applicable protocol.

How India regulates import and export

The Department of Animal Husbandry and Dairying regulates imports under the Live-stock Importation Act, 1898 (as amended). As of September 2026, DAHD Trade guidance summarizes the split as follows:

• Live animals are generally on the restricted list under foreign-trade policy. Importers typically need a licence from the Directorate General of Foreign Trade (DGFT) after departmental recommendation and risk analysis, except for limited pet-dog and pet-cat baggage cases described in Customs circulars.
• Livestock products often require a Sanitary Import Permit (SIP) issued by the Department after import risk analysis. DAHD notes that an SIP is not a licence but a certificate of India's sanitary requirements, typically valid from three months to one year depending on the product.

AQCS import procedures describe Customs referral of consignments for animal quarantine clearance, examination of official health certificates, risk analysis, quarantine observation and testing for livestock, and immediate, provisional, or hold clearances. Non-compliant consignments may be deported or destroyed. For livestock under DGFT licence or SIP, AQCS states that an advance NOC may be issued within seven days of arrival based on advance document copies, with final clearance after post-import rules.

On export, AQCS describes an internationally acceptable certification service aligned with WOAH Terrestrial Animal Health Code Chapter 5.2 (Articles 5.2.1 to 5.2.4). AQCS veterinarians act as official veterinarians of India's Veterinary Authority. AQCS notes that livestock meant for export must be microchipped for better identification, and that an export quarantine certificate is issued after physical examination or quarantine observation, typically within two to three days before departure when the animal is fit.

“Except for import of pets under baggage, all animals are quarantined. Pets under baggage can also be quarantined in case of doubt.” — Animal Quarantine and Certification Service FAQ, Government of India

International standard: WOAH Terrestrial Animal Health Code

National services do not invent the grammar of trade alone. The World Organisation for Animal Health (WOAH, formerly OIE) Terrestrial Animal Health Code Section 5 covers trade measures, import/export procedures, and veterinary certification. Chapter 5.1 (most recent update adopted in 2024) states that Veterinary Authorities should base import requirements on WOAH standards, or on import risk analysis when they choose a higher level of protection.

Chapter 5.6 (border posts and quarantine stations; most recent update adopted in 2024) recommends that border posts and quarantine stations have adequate organisation and equipment, including facilities for feeding and watering animals. Where trade volume and epidemiology justify it, stations should support clinical examination, diagnostic sampling, isolation of diseased or suspect animals, and vehicle disinfection. Critically, WOAH states that the presence of disease or infection in imported animals in a quarantine station does not affect the animal health status of the country or zone.

Chapter 5.7 (animal health measures on arrival) sets the default rule: an importing country should only accept animals that have been examined by an Official Veterinarian of the exporting country and that are accompanied by an international veterinary certificate from that country's Veterinary Authority. Animals without a conforming certificate, or animals found diseased or suspect at the border, may be refused entry, placed in quarantine for diagnosis, returned, or—when return is unsafe or impractical—slaughtered and destroyed.

United States comparison: USDA APHIS Veterinary Services

In the United States, the parallel functions sit with USDA APHIS Veterinary Services. APHIS regulates import of specific live animals and germplasm to prevent foreign animal disease spread. As of September 2026, APHIS live-animal import guidance emphasises species-specific permits, veterinary export health certificates, port inspection, and—when required—import quarantine.

APHIS Animal Import Centers exist to keep imported birds, poultry, equines, ruminants, swine, and certain zoo animals separate while monitoring for disease and performing import testing. The Miami Animal Import Center (opened September 2004) focuses on avian imports adjacent to Miami International Airport. The New York Animal Import Center in Rock Tavern, New York (opened 1980; 53 acres), receives birds, poultry, equines, ruminants, swine, and certain zoo animals near major New York-area airports.

Concrete U.S. examples illustrate how quarantine length is not one-size-fits-all:

• Live poultry — USDA requires a USDA import permit, veterinary export health certificate, port inspection, and a minimum of 30 days quarantine at a USDA Animal Import Center or USDA-approved private facility (with specified Canada exceptions). Importers must reserve space before shipment; USDA confirms the reservation before issuing the import permit (APHIS live-poultry guidance, last modified June 2026).
• Live equines — USDA generally requires permit, certificate, port inspection, and import quarantine for live equines, except horses from Canada. Quarantine may be 3, 7, or 60 days based on residency and transit health status and purpose of entry. Importers must reserve APHIS-approved quarantine space at least three business days before arrival (APHIS equine import guidance).

For exports from the United States, APHIS states that exporters should contact a USDA-accredited veterinarian early, confirm destination requirements (which can change without notice), and obtain USDA-endorsed health certificates. The Veterinary Export Health Certification System (VEHCS) is APHIS's secure online system for creating, issuing, submitting, and endorsing health certificates for international export of live animals and germplasm. The National Veterinary Accreditation Program (NVAP) reference guide notes that most importing countries require APHIS Veterinary Services endorsement of international health certificates.

Import vs export: what each side usually requires

APHIS FAQ guidance (May 2026) warns that the full process can take from a few weeks to many months, and that some animals need pre-export isolation lasting weeks to months before they may present for U.S. entry. Importers who cannot meet certificate or permit conditions face refusal of entry and possible financial loss.

How digital livestock identity fits—without replacing official papers

Border quarantine and certification depend on trustworthy animal identity: which animal was tested, vaccinated, isolated, and listed on the certificate. Official systems use microchips, brands, tattoos, and paper or electronic government certificates. AQCS, for example, requires microchipping of livestock meant for export for better identification.

Animal Passport is a digital animal and livestock passport that uses muzzle biometrics (a nose print unique like a fingerprint). Capture is phone-based. The record binds owner, breed, estimated age, body condition, and vaccination history. Age can be estimated from a dental photograph with a confidence score, and body condition can be scored 1–5 from a side-profile photo. In livestock flood rescue in Pakistan in August 2025, the tool helped farmers reclaim animals when paper tags washed away.

That field experience shows why durable identity matters when paper fails. It does not mean Animal Passport is a government-issued travel document, an AQCS clearance, a USDA import permit, an EU pet passport, or a substitute for WOAH-aligned international veterinary certificates. EU pet passports, the UK PETS-related pet travel framework, and airline pet carriage rules are separate official or carrier regimes. For more context on farm identity workflows, see the Animal Passport blog.

Practical checklist before you move animals across a border

1. Identify the Competent Authority or Veterinary Authority in both countries (WOAH member listings help).
2. Confirm whether the commodity needs a licence, SIP, or import permit, and whether the species is even eligible.
3. Obtain the current health protocol: tests, vaccines, isolation periods, certificate wording, and language requirements.
4. Book quarantine space early when post-arrival hold is required; APHIS and AQCS both emphasise advance coordination.
5. Ensure animal identification on the certificate matches the animal presented (microchip numbers, markings, and ownership details).
6. Budget for user fees: inspection, quarantine stay, and laboratory testing are typically charged to the importer.
7. Do not confuse private digital IDs, airline forms, or pet travel documents with livestock quarantine clearance.

As of September 2026, rules change by disease status and trade notices. Always re-check primary government pages—AQCS, DAHD Trade, USDA APHIS species pages, and WOAH Code chapters—before shipping.
