FDA Structured Product Labeling (SPL) Preparation

FDA requires Structured Product Labeling (SPL) — an XML-based format — for drug listing, establishment registration, and NDC submissions. LMG prepares error-free, submission-ready SPL files powered by our proprietary LMG SPLmatrix™ platform.

About FDA SPL Preparation

Structured Product Labeling (SPL) is the FDA’s mandatory XML-based document standard for submitting drug information to the FDA’s electronic systems under 21 CFR Part 207. All drug companies registering facilities or listing products in the United States must submit SPL files through the FDA Electronic Submissions Gateway (ESG).

Incorrect or malformed SPL files are one of the most common causes of registration rejections and delays. LMG’s proprietary LMG SPLmatrix™ platform eliminates these errors by automating the entire SPL generation process with built-in FDA schema validation — ensuring first-time acceptance.

Our SPL preparation services cover:

  • Drug Establishment Registration (21 CFR 207)
  • Drug Listing & Annual Updates (21 CFR 207.57)
  • NDC Labeler Code Applications
  • OTC Drug Product Listing
  • Prescription Drug Product Listing
  • Active Pharmaceutical Ingredient (API) Listing
  • Structured Dosage Form & Route of Administration Coding
  • FDA ESG Submission, Tracking & Confirmation

At Liberty Management Group, our regulatory team handles the entire SPL workflow — from data collection and XML generation through FDA ESG submission and confirmation — using LMG SPLmatrix™ for zero-error submissions.

How SPL Preparation Works at LMG

Our streamlined 4-step process — powered by LMG SPLmatrix™ — ensures your SPL submission is accurate, validated, and submitted on time.

Step 1 — Data Collection & Review
We provide a structured intake form to collect all required product and facility data: establishment information, product names, dosage forms, routes of administration, active and inactive ingredients, NDC numbers, and labeler code. Our regulatory team reviews your existing labels and prior registrations before proceeding.
Step 2 — SPL Generation via LMG SPLmatrix™
Our regulatory specialists input validated data into LMG SPLmatrix™, which generates FDA-compliant SPL XML files. The platform automatically applies current FDA terminology standards (SNOMED CT, FDA-maintained code systems) and validates output against the current FDA SPL schema — catching errors before submission.
Step 3 — Client Review & Sign-Off
You receive a human-readable summary of the SPL content for your review and approval. Our team addresses any queries before submission. For new clients, we confirm your product and facility data is complete before LMG submits via our registered FDA ESG account.
Step 4 — FDA ESG Submission & Confirmation
LMG submits your SPL file directly to the FDA Electronic Submissions Gateway (ESG). You receive the submission confirmation ID and, upon successful processing, the updated FDA registration record. We handle all error responses and resubmissions at no additional charge.

SPL Preparation — Frequently Asked Questions

Common questions about FDA Structured Product Labeling (SPL) requirements and the LMG SPLmatrix™ process.
Structured Product Labeling (SPL) is the FDA-mandated XML-based document standard for submitting drug product information to FDA’s electronic systems. It is used for drug establishment registration, drug listing, NDC labeler code applications, and related submissions through the FDA Electronic Submissions Gateway (ESG) under 21 CFR Part 207. All SPL files must conform to the current FDA SPL schema.
SPL is required for: (1) Drug establishment registration and renewal under 21 CFR 207; (2) Drug listing — initial listing and annual updates under 21 CFR 207.57; (3) NDC labeler code applications; (4) OTC and prescription drug product listings; (5) Homeopathic drug listings; (6) API (Active Pharmaceutical Ingredient) listings. Both domestic and foreign drug manufacturers must comply. Foreign manufacturers must submit through a U.S. FDA Agent.
LMG SPLmatrix™ is Liberty Management Group’s proprietary software developed in-house for FDA SPL preparation. It automates the generation of valid, schema-compliant SPL XML files from structured product data, runs pre-submission validation checks, and submits directly to the FDA ESG. This eliminates formatting errors, missing mandatory fields, and incorrect code system values — the most common causes of SPL submission rejection. Because it is built and maintained entirely by LMG, the platform is always current with the latest FDA SPL schema updates.
No. Foreign drug manufacturers must designate a U.S. FDA Agent before submitting registration or listing information to FDA. The U.S. Agent is the official point of contact between FDA and the foreign manufacturer. LMG provides both U.S. Agent services and SPL preparation via LMG SPLmatrix™, offering a complete solution for foreign manufacturers entering the U.S. market.
Using LMG SPLmatrix™, our team typically delivers completed, validated SPL files within 3–5 business days from receipt of all required product and facility data. Expedited service is available upon request for urgent registration deadlines. Multi-product portfolios are scoped individually — contact us for a timeline estimate.
LMG monitors all submissions through the FDA ESG and handles all error responses at no additional charge. If FDA returns a technical rejection, our team analyzes the rejection reason, corrects the SPL file in LMG SPLmatrix™, and resubmits promptly — usually within 1 business day of receiving the FDA response.
SPL preparation and drug label review are separate services. SPL preparation creates the XML submission file for the FDA database. Drug label review is a compliance audit of your physical product label against the FD&C Act, OTC monograph requirements, Drug Facts panel rules, and marketing claim standards. LMG offers both — contact us to bundle them at a reduced combined fee.
