A Global Practice with Real FDA Experience
I3CGlobal serves manufacturers across India, Germany, the UK, the USA, South Korea, Vietnam, Malaysia, the Middle East, and Europe. Our global reach means we understand the specific challenges that international manufacturers face when targeting the US market — language barriers, facility design gaps, documentation practices, and cultural differences in how quality systems are built and run.
We bridge that gap. Not by pointing to regulations, but by working alongside your team to build the systems, documentation, and readiness that the FDA actually expects to see.

What Our FDA Consultants Do
Manufacturers come to our FDA consultants for different reasons. Some are entering the US market for the first time. Others are two weeks out from an FDA inspection. A few have already received a warning letter. The starting point changes — the goal is always the same.
GMP Implementation & Certification: Getting your quality system right is the foundation of everything else. We work with manufacturers on MDSAP, 21 CFR 820, 21 CFR 111, and 21 CFR 211 — setting up systems that hold up during an actual FDA audit, not just on paper.
FDA Pre-Inspection & Mock Inspections: An FDA investigator walking through your facility will find things. The question is whether you find them first. Our mock inspections put your site through the same scrutiny — giving you time to fix issues before they become official observations.
Product Labeling — GAP Assessment & Guidance: FDA labeling requirements are specific. A gap assessment tells you exactly where your current labels fall short — product by product, claim by claim — before your product enters the US market.
FDA Form 483 Responses: Fifteen working days. That’s how long you have to respond to a 483. A weak response increases the chance of a warning letter. We write responses that are technically accurate, well-evidenced, and built around a CAPA plan the FDA will find credible.
Warning Letter Remediation: A warning letter signals the FDA has lost confidence in your operation. Rebuilding that trust takes more than a written response. We help manufacturers put together a remediation plan that addresses root causes — and follow through until FDA closes the matter.
FDA DMF Preparation & Submission: Drug Master Files require precise documentation and careful formatting. We handle preparation, submission, and any follow-up correspondence with FDA across all DMF types.
FDA 510(k) Preparation & Submission: A cleared 510(k) starts with the right predicate device. From there, the substantial equivalence argument, performance data, and submission package all have to hold together. We manage that process start to finish — and know where most submissions run into trouble.
Product Classification: Before any regulatory pathway can be planned, the product has to be correctly classified. Device, drug, biologic, combination product — each carries different requirements. We work through the classification with you and lay out what it means for your path to market.
Pre FDA Inspection Support Service
An FDA inspection is one of the most high-stakes events a manufacturer will face. One unresolved gap, one poorly answered question, one missing SOP and you’re looking at a Form 483, a warning letter, or worse, an import alert. The FDA doesn’t grade on effort. They inspect what’s actually in place. That’s why preparation isn’t optional. It’s the difference between a clean inspection and a compliance crisis.
I3CGlobal’s Pre-FDA Inspection Support Service is designed to get your facility, your team, and your quality system genuinely ready not just rehearsed. We work with manufacturers of all sizes, from first-time FDA registrants to established exporters who’ve had previous observations and need to come back stronger.
Types of FDA Inspections we prepare you for..
FDA inspections are not all the same. Each type carries different expectations, different levels of scrutiny, and different consequences if you’re not ready. Our Pre-FDA Inspection Support Service covers all four categories:
Pre-Approval Inspections (PAI) — Triggered by a pending 510(k), PMA, or NDA/ANDA submission. The FDA wants to verify that your facility and quality system can actually produce what you’re claiming in your application. Gaps between your submission and your actual operations are a common failure point. We close those gaps before the investigator arrives.
Routine Surveillance Inspections — These happen on a scheduled cycle for registered facilities. They may feel routine, but they carry real enforcement risk. Our team conducts a comprehensive pre-inspection readiness review to ensure your quality system, records, and facility are audit-ready at all times — not just the week before.
Compliance Follow-Up Inspections — If your facility has previously received a Form 483 or warning letter, the FDA will return to verify that your corrective actions are real and sustained. These inspections are higher stakes. We help manufactures implement a strong compliance and demonstrates genuine systemic change not just surface-level fixes.
“For Cause” Inspections – These can be triggered by scheduled or short notice complaints, adverse event reports, whistleblowers, or intelligence received by the FDA. may be given little or no warning in advance. That’s where our rapid-response preparation service comes in, helping you mobilise swiftly, get your documents in order, and prepare your team to respond with confidence.
US FDA Audit & FDA 483 response
The Notice of Inspectional Observations, officially known as FDA Form 483, is typically issued by an FDA officer in response to a violation of Good Manufacturing Practices (GMP) in the food, drug, medical device, or cosmetic manufacturing or supply chain after the scheduled onsite audit.
Recipients of a US FDA 483 warning letter, whether by post or email, are required to respond to the FDA within 15 working days. Manufacturers must understand that a non-technical or poorly constructed response may result in a permanent warning and increased chances of further enforcement action by the FDA, including repeated inspections at short notice.
In any case, a Corrective and Preventive Action (CAPA) plan with a detailed schedule and timeline must be submitted. This is where the expertise of US FDA Consultants becomes invaluable. They can help ensure that the response is comprehensive, technically sound, and meets the FDA’s expectations.
This can greatly reduce the risk of further enforcement actions and help manufacturers maintain compliance with FDA regulations. I3CGlobal team of experts help manufacturers respond to FDA.
